World trends

War & Conflict

The biggest variable between 30 August and 1 September is the reignition of the US-Iran front. After about a month of calm, US forces destroyed two IRGC rocket launchers on Larak island in Hormuz, and Iran carried out its promised retaliation. It fired ballistic missiles at Jordan's King Hussein and Al-Azraq air bases and claimed to have struck the UAE's Al Minhad base. This is a qualitative shift as the front spreads beyond Iran's mainland to countries hosting US forces in the region, and together with the de facto closure of Hormuz since 28 February it is squeezing energy logistics. In Yemen too, the Houthis have repeatedly attacked the Saudi Jazan refinery and Red Sea tankers since declaring a blockade on 20 July, destabilising Gulf-Red Sea routes. The second axis is the durability of regimes in Africa. In Niger, a mutiny of several hundred soldiers at Niamey's Air Base 101 on 29-30 August attacked the airport and the presidential palace and was put down with direct intervention by Russia's Africa Corps. It is unprecedented for a junta to use a foreign paramilitary force on an internal matter, and doubts about cohesion have grown as Tchiani has not appeared in public for a third day. In Sudan, after the RSF offensive in Blue Nile state captured Geissan and Kurmuk, a counterattack on 27 August displaced 13,970 people, and in Ethiopia a renewal of fighting in western Tigray coincided with signs of mutual understanding between Amhara and Tigray, putting the Red Sea-Nile corridor into a structure of linked instability. Some fronts, by contrast, have a living negotiating track. The Democratic Republic of the Congo and M23 agreed a Doha roadmap on 23 August and a ceasefire verification mission deployed to Minembwe in South Kivu on 24 August, the clearest sign of easing in this phase. However, claims of a drone strike on Minembwe came the same day, so confidence in implementation remains fragile. In Gaza, envoy Mladenov warned that the ceasefire is nearing a "point of no return," and deployment of the advance team of the International Stabilization Force and disbursement of $7 billion in reconstruction funds are delayed. In Lebanon, Qassem again rejected the June framework agreement on 29 August, dimming prospects for a resumption of talks in early September. In Russia-Ukraine, the death toll from the explosion at the Bucha Mila ammunition depot was confirmed at 38 and Russia has flagged a major strike on the power grid, so a winter energy war is imminent. The Kenscoff massacre in Haiti (47 dead, about 50 kidnapped) and air strikes in Myanmar's Rakhine and Chin states (civilian casualties in August exceeding 100) show the persistence of state-collapse-type violence. Venezuela and Taiwan have shifted to non-military competition, resource and economic restructuring and grey-zone pressure respectively.

Geopolitics & Diplomacy

The 26th Shanghai Cooperation Organisation (SCO) summit, held in Bishkek on 31 August-1 September, was staged as a showcase of a 'non-Western multipolar order', with the added symbolism of the bloc's 25th anniversary. Xi Jinping, Putin, Modi, Pezeshkian, Shehbaz Sharif and Erdogan were all present, and Kyrgyz President Sadyr Japarov chaired the meeting as host. Substantive results, however, remained declaratory. The Power of Siberia 2 gas pipeline, the most closely watched item, was not settled at the Xi-Putin talks on 31 August and, as Kremlin aide Yuri Ushakov had signalled, discussion moved to the Eastern Economic Forum in Vladivostok. Spokesman Peskov said the talks were focused on the economy and that Ukraine was touched on only 'in passing'. Xi spoke of 'even brighter prospects' and Putin of 'successful cooperation in all areas', but the deadlock over pricing remains. The bilateral track, by contrast, was busy. Modi pressed Putin to end the war, saying 'every day spent in war pushes humanity backwards', and Putin showed off the relationship by citing a 2.6% rise in first-half trade and 40,000 Indian students in Russia (a sevenfold increase). Shehbaz Sharif agreed with Uzbek President Mirziyoyev on $2 billion in trade by 2029 and progress on the Uzbekistan-Afghanistan-Pakistan railway. The chairmanship passes to Pakistan and runs until 2027. Separately from the SCO, Xi made a state visit to Kyrgyzstan, declaring a 'golden age', which reveals a trend of eroding Russia's sphere of influence in Central Asia.

In the Middle East, the US-Israeli war on Iran, which began on 28 February 2026, flared up again at its largest scale on 30-31 August, just past the six-month mark. After US forces struck two Iranian rocket launchers on Larak Island in the Strait of Hormuz on 30 August (citing preparations to launch mine-carrying missiles), Iran's Revolutionary Guards retaliated with missiles and drones against Jordan's King Hussein and Al-Azraq bases and the UAE's Al Minhad base. Jordan intercepted eight missiles and there were no hits. On 31 August President Trump posted an AI-generated video depicting a strike on the Kharg Island refinery, and Vice President Vance warned Iran 'not to act like a terrorist state'. At the same time, Washington's centre of gravity shifted to economic warfare. After the 'Economic Outcast' operation against about 60 targets on 24 August, the UAE branch of Egypt's Banque Misr was sanctioned on 30 August over alleged links to an Iranian shadow financial network (103 companies, $1.8 billion, from January 2024 to June 2026), and Treasury Secretary Bessent promised weekly secondary sanctions. Iran's inflation is 66%, its exports and imports are down 35%, and about 400 ships and 6,000 seafarers are stranded by the Hormuz blockade. Supreme Leader Mojtaba Khamenei sent a letter to Gulf leaders on 30 August urging them to confront the 'real enemy', but the Gulf is responding instead with overlapping security networks, including the 7 August Saudi-Turkey-Pakistan 'Mecca joint defence pact', a reaffirmed GCC joint defence agreement and joint UK-Qatar Typhoon squadrons. In Gaza, Nickolay Mladenov, head of the Board of Peace, warned on 26 August that the collapse of the ceasefire could become a 'point of no return', and seven countries issued a joint statement condemning the West Bank E1 settlement tender (1,200 homes to start, 3,400 in total).

On the Western Hemisphere and Atlantic axis, US unilateralism shook allies and neighbours alike. On 29 August President Trump declared the 'largest oil deal in world history', saying the US had secured control over Venezuelan reserves of more than 65 billion barrels and 17 oil fields, but the US account (100 years) and that of interim President Delcy Rodriguez (25 years) clash head-on over the contract term, and the contract and participating companies have not been disclosed. Harvard's Ricardo Hausmann called it a 'shameful deal', protests were held in Caracas, and opposition leader Machado voiced caution that it was 'a deal with Maduro's associates'. To the north, after the 22 August collapse of trade talks, the US imposed 50% tariffs on $20 billion of Canadian goods, and Prime Minister Carney responded with retaliatory tariffs taking effect on 8 September (more than 700 items, $19.9 billion, 15-50%) and allocated $5.42 billion in support for small businesses. The Kiel Institute estimated that the US side absorbs 96% of the tariff burden. Mexico's Sheinbaum government is avoiding a direct clash and cushioning it with security cooperation, including a declaration of access to drone technology and the handover of nine wanted individuals. In Europe, a Pentagon force-posture review is on a schedule to send at least four options to Secretary Hegseth before 6 November, with a demand spelled out that 'at least some options' must envisage cutting 80,000 troops stationed in Europe. In a referendum on 29 August, Iceland rejected resuming EU accession talks by 52.5% to 47.5%, with Trump's remarks about Greenland and Iceland having, if anything, brought the vote forward.

In Africa and the Balkans, state legitimacy and the politics of memory were shaken at the same time. In Niger, hundreds of soldiers mutinied at Base 101 on the grounds of Niamey international airport shortly after midnight on 29 August, and government forces retook it on 30 August. Dozens of the mutineers were killed or arrested; they are reported to be from Ouallam, Tera and Dosso, areas that suffered heavy losses fighting jihadist militants. It is the third attack on a base this year alone. Critically, junta leader Abdourahamane Tiani had not appeared in public as of the morning of 30 August, leaving questions about his control. Algeria sent four fighter jets and transport and refuelling aircraft, and Russia's Africa Corps was also asked to help put down the revolt, highlighting a pattern of military competition between Russia and Algeria in the Sahel. In the Balkans, the controversy grew after the Serbian government promised on 28 August 'all military and state honours' for Ratko Mladic, who died in The Hague on 27 August. As of 31 August, no funeral date had been fixed and procedures with the IRMCT for the release of the body remain. President Vucic criticised the UN tribunal without saying whether there would be a state funeral; memorial gatherings were held across Republika Srpska, while Sarajevo marked the anniversary of the Markale massacre. Srebrenica survivors said 'his ideas have not died' and criticised state honours as turning private mourning into national glorification of a war criminal. The issue bears directly on Serbia's status as an EU candidate. Meanwhile, in the Indo-Pacific, South Korea, the US and Japan will hold the fourth 'Freedom Edge' exercise southeast of Jeju on 7-11 September, drawing North Korean threats of retaliation, and a glacier collapse on the Nepal-Tibet border has caused a disaster with more than 900 dead and more than 3,000 missing, with damage estimated at $4-5 billion.

Finance & Economy

The single variable that dominated global financial markets on 31 August was oil. After US forces struck two Iranian rocket launchers on Larak Island in the Strait of Hormuz on 30 August - the first publicly confirmed direct clash between the two countries since late July - Brent jumped to $91.09 intraday before closing at $90.49 (+2.71%), and WTI settled at $85.76 (+2.83%). That is a rise of about $2.5 each from the previous close of $83.3 and $88.6. Notably, the market translated the event not as "geopolitical risk" but as "inflation risk". The safe-haven rally usually seen in a military clash did not appear. Gold actually fell 0.64% to $4,466, the VIX stayed near 15 at 14.92, and the US 10-year yield rose to 4.76%, its highest since January 2025. The causal chain of higher oil, higher inflation expectations, stronger bets on a Fed hike, higher real yields and weaker non-yielding assets (gold) played out exactly as described. This implies the market is ruling out extreme supply-disruption scenarios such as a Hormuz closure and pricing the oil upside only through the inflation channel. In other words, an asymmetric vulnerability is building: if an actual closure of the strait or a large-scale Iranian retaliation materialised, the market would be wholly unprepared.

The second axis is that the internal US policy clash between the Warsh Fed and the Bessent Treasury has come into full view. After Fed Chair Kevin Warsh signalled a hawkish stance at Jackson Hole on 28 August, saying "inflation is running too hot", the probability of a rate hike at the September FOMC, per CME FedWatch, nearly doubled in just three days: 35-40% just before the speech, 57% on 30 August, and 65.9-66% at the 31 August close. The surge in oil on 31 August was the final push. The Treasury, meanwhile, is moving in the opposite direction. Treasury Secretary Bessent announced a surprise expansion of liquidity-support buybacks of long-dated nominal Treasuries on 19 August, and has now formally said the size per operation will rise to around $4 billion from 9 September. This is a response to the 30-year yield hitting 5.33% in mid-August, a 19-year high. Analysts read it as a policy mismatch in which the Fed tightens while the Treasury loosens, and even as de facto yield-curve intervention by the fiscal authority, raising debate over damage to Fed independence. The 10-year's renewed rise to 4.76% on 31 August shows the buyback effect has already been exhausted. Until the 15-16 September FOMC, this clash is expected to be the main source of bond-market volatility over the next two weeks.

The third axis is South Korea's lone strength. On 31 August the KOSPI plunged more than 3% early in the session to the 6,600 level on the Warsh shock and Middle East risk, then staged a dramatic reversal in the afternoon on dip-buying in chips to close up 0.46% at 6,820.02. Individual investors net bought ₩310.3 billion to support the index, and Samsung Electronics surged on reports of HBM4 mass-production momentum and yield improvements, leading the gain. Meanwhile, the USD/KRW close in Seoul daytime trading on 31 August was confirmed at ₩1,368.6 (-₩3.9). That is the first close in the ₩1,360s in 13 months, and the won gained about ₩50 (3.5%) from ₩1,418 over August, making it the strongest major Asian currency. The reason the won alone ran against the Warsh-driven global dollar rally is clear: the HBM supercycle, in which exports for 1-20 August jumped 56% year on year with chips accounting for nearly half. The August trade data due on 1 September is likely to set an all-time record. The risks are also clear. First, export growth is extremely skewed towards semiconductors, an illusion that masks weakness in other industries. Second, the oil surge that began on 31 August will, with a lag, push up import bills, eroding the trade surplus and weakening the driver of won strength. Third, if a September FOMC hike materialises, a wider Korea-US rate gap would be a headwind for the won. Elsewhere, in Europe, German August CPI of +2.9% and French HICP of +2.7% confirmed a re-acceleration in prices, raising wariness ahead of the eurozone flash HICP on 1 September and the ECB meeting on 9-10 September; China's August manufacturing PMI rebounded to 49.8 but stayed in contraction for a fifth straight month; and India kept the fastest growth among major economies with first-quarter GDP growth of 7.8%.

Tech & Energy

US Section 232 semiconductor tariffs stalled at the threshold of ‘phase two’ in late August. Phase one, signed on 14 January 2026, imposes 25% only on certain advanced AI accelerators and carves out six exemptions: data centres, R&D, start-ups, repairs, consumer/industrial use and the public sector. Phase two would widen the scope to finished products such as laptops, game consoles and data-centre servers and strip away existing exemptions, including the exemption code for data centres of 100MW or more (9903.79.03). But as of 1 September neither the rate nor the start date has been set, and the Commerce Department market investigation report that triggers phase two, although completed by its 1 July deadline, had not been released as of 30 August. This ‘completed but unpublished report’ is in effect holding the entire global chip supply chain hostage. The alternative being pushed by Commerce Secretary Lutnick is a formula that allocates tariff-free import quotas in proportion to the size of US chip production investment. It is already reflected in the US-Taiwan trade agreement, under which TSMC can import tariff-free up to 2.5 times its current US production capacity during construction and 1.5 times after operations begin. The problem is that this quota covers only about 45% of TSMC's current total output. In addition, to receive the AMIC 35% tax credit, construction must start by 31 December 2026, but legislation to extend the deadline has not passed, so US chip investment announced at $640 billion is frozen under the double uncertainty of an unset tariff rate and the construction deadline. This design, which uses tariffs as a weapon to draw out investment while exempting firms that invest, effectively marks a shift to a structure in which the US signs industrial-policy contracts with individual companies one by one.

The Power of Siberia 2 gas pipeline was ultimately not concluded. President Putin arrived in Bishkek, Kyrgyzstan, on 31 August and held bilateral talks with President Xi Jinping as the first item on his SCO summit schedule, discussing the pipeline, but as of the morning of 1 September Korea time, no signing or announcement of a deal had been confirmed. Asked whether the agreement would be finalised, Kremlin aide Yuri Ushakov said it ‘will be discussed at the bilateral level’ and also mentioned the Eastern Economic Forum in Vladivostok on 1-4 September, so the Russian side itself did not signal a conclusion at these talks. It is the second miss, after the 20 May Beijing summit. The core obstacle is still price. Russia demands a profitable unit price to make up for lost European markets, while China insists on a low price close to its domestic sales price. China holds alternatives in Central Asian pipeline gas, Qatari and US LNG and expanded domestic renewables, so it has no reason to hurry, and this asymmetry reveals the real power structure of the relationship, despite the rhetoric of ‘limitless cooperation’. However, the prolonged blockade of the Strait of Hormuz has raised the risk of procuring Middle Eastern oil and LNG, the only variable that could change China's calculations. The next turning point is Putin's speech at the Eastern Economic Forum in Vladivostok on 1-3 September.

Egypt has become a new proving ground in the US-China contest for AI technology supremacy. Huawei has submitted a proposal, in a consortium with voice-recognition and surveillance firm iFlytek, to build 2,008 Ascend processors (1,408 of the 950 series for training and 600 of the 950DT/910B for inference) within 12 months. The 102-page proposal includes vehicle and personal recognition, linkage to population databases and city-wide situational-awareness surveillance, making it more a governance-technology package than simple AI infrastructure. In raw compute it equals only a few hundred of Nvidia's top processors, small next to large Western deployments, but if it goes ahead it would be the first official export of Ascend chips and Huawei's first breakthrough in overseas sales after years of failures in the Gulf and Southeast Asia. Around 26 August the US State Department sounded out Nvidia, AMD and Microsoft about forming a rival consortium, but none of the three confirmed participation, and Microsoft declined to comment. After finishing the SCO schedule in Bishkek, President Xi began a state visit to Egypt on 30 August-3 September, the first in ten years since January 2016 and coinciding with the 70th anniversary of diplomatic ties. But as of the morning of 1 September, no contract award had been announced and Egypt has not stated a preference. Egypt is using the project as negotiating leverage between US security and financial support and Chinese infrastructure funding, and an announcement during the visit remains possible, so a conclusion could come within days.

Far from progressing, talks on reopening the Strait of Hormuz have slid back into military confrontation. On 30 August, US forces detected signs that Iran was trying to re-lay mines in the shipping lane and struck IRGC rocket launchers on Larak Island. Within hours Iran retaliated under an ‘Operation to Punish the Aggressor’, hitting Jordan's King Hussein and Al-Azraq bases and UAE military facilities with ballistic missiles and drones. Jordan intercepted eight missiles and the UAE intercepted drones. A framework for a temporary joint navigation corridor 7 miles wide, announced by Iran and Oman five days before the strike, has effectively been frozen after Iran tied it to full US acceptance of its conditions. The six conditions announced by Iran's Supreme National Security Council in August are an end to threats against Iran, a permanent halt to attacks on Iran and its allies, lifting of the naval blockade and withdrawal of US forces, compensation for damage from the war that began on 28 February 2026 and from Israel's 2025 war, a full lifting of sanctions, and return of frozen assets, none of which Washington is likely to accept. The 17 June memorandum of understanding expired on 17 August, and on 27 August the White House confirmed there were no talks under way. The market impact is real. Brent has topped $90 a barrel, the US national average gasoline price is $4.08 a gallon, Gulf exports have fallen from 22-24 million barrels a day before the war to 15-16 million, and Iranian oil exports have been effectively zero since mid-July. The Larak strike put added pressure on an already strained war-risk insurance market. The OPEC+ meeting on 6 September is the next turning point.

Nvidia’s suspension on 27-28 August of the $36 billion ‘AI Compute Partnership’ it launched in July exposed structural limits in the financing model for AI infrastructure. Under a six-year contract structure, Nvidia would supply GPUs and funding while cloud providers shared revenue, but the problem was not money but control. Partners objected to clauses under which Nvidia would vet partners’ end customers in advance and require them to spread capacity across many small and mid-sized AI firms rather than concentrate it on one large buyer, and concerns about antitrust exposure were also raised internally. The confirmed initial partners are Sharon AI and Firmus Technologies. Nvidia said ‘the new business model remains valid’, leaving open the possibility of a redesign. By contrast, Anthropic signed a $45 billion compute capacity deal with UK-based Nscale on 26-27 August, and India's Yotta ordered 50,000 Nvidia Vera Rubin chips for $7.5 billion plus an additional 45,000 GB300s, and is preparing an IPO at a $6 billion valuation raising $900 million. It is a sign that a structure in which AI developers sign long-term capacity deals directly with infrastructure operators, who in turn raise funds directly in capital markets, is gaining the upper hand over chip-supplier-led financing. The lesson of this episode is that a chip supplier that tries to control demand, funding and even customer selection runs into the antitrust threshold.

Local and political backlash against data centres is erupting in several countries at once, but governments’ responses are diverging sharply. In the UK, 14 campaign groups will hold a solidarity rally outside the Scottish Parliament on 3 September. According to APRS figures, 20 data centres with combined power demand of 7GW are going through the planning process in Scotland, with at least three more proposals not yet submitted. Their demands are an immediate halt to approvals, mandatory environmental impact assessments for hyperscale facilities, independent assessment of need and local impact, and full planning applications rather than approval in principle. The Scottish government has introduced monitoring that requires local authorities to notify it within seven days of applications above 50MW. In England, Green Party leader Zack Polanski called on 28 August for a halt to new approvals nationwide. His argument was that a single large data centre uses about 1.5 million litres a day (the demand of a town of 10,000 people) while more than 27 million people face drought restrictions, but the UK government and Labour dismissed it on 31 August, saying it would ‘send investment and jobs overseas’. On 28 August, New Jersey in the US signed a law requiring disclosure of power and water use. Australia went the other way. After Queensland and the Northern Territory pushed back at a national cabinet in Sydney on 26 August, Energy Minister Chris Bowen on 28 August changed ‘100% renewables backed by pumping’ to count gas-fired generation as part of the pumping, effectively watering down the renewables mandate, and legislation was pushed to early 2027. In Italy, grid connection applications exceeded 95GW (342 requests), up sharply from 1GW in 2021, and the grid queue itself has become the biggest constraint. In Germany, the Schwarz Group will invest €5.6 billion in a facility near Rostock, 240MW in 2033 and up to 1GW by 2045, run entirely on renewable energy, offering a ‘backlash-avoidance model’.

Equipment and materials export controls have moved into a stage where the US directly pressures allies’ sovereignty. The MATCH Act (S.4281) is on track to be folded into the National Defense Authorization Act (NDAA), and if passed, ASML would be barred not only from selling the older DUV tools now permitted to China but also from maintaining and supplying parts for equipment already delivered. Maintenance is a higher-margin and steadier revenue source than equipment sales, so the blow would be large, and Chinese fabs are rushing to stockpile parts and build their own servicing capability. The Dutch government is lobbying hard in Washington and holds that export controls are a matter of its sovereignty, but with the bill enjoying bipartisan support, its chances of stopping it are rated low. At the same time, the Nexperia dispute has run on into 2026, with China countering an investigation order from a Dutch court with a warning, and Nexperia’s China unit switching its wafer suppliers to local firms. Qualifying a new supplier takes up to six months, and in the meantime legacy chip supply for cars has been disrupted and some production lines halted. It confirms that supply-chain fragmentation hits the real economy immediately not only in advanced nodes but also in legacy chips. Meanwhile, countries are leaning towards state-capitalist responses. Japan put ¥150 billion into Rapidus on 5 June, bringing government and private funding to ¥267.6 billion, switched its support from subsidies to direct government equity holdings, and is reported to be considering a further ¥1 trillion in aid and targets of profitability in FY2030 and a listing in FY2031. In South Korea, SK Hynix broke ground on 28 August on a $4 billion (about ₩5.5 trillion) HBM packaging plant in Indiana, targeting mass production in the third quarter of 2029, but on 31 August Samsung Electronics (-3.40%, ₩248,250) and SK Hynix (-3.21%) fell together on hawkish remarks from Fed Chair Warsh and a 3.47% plunge in the Philadelphia Semiconductor Index.

Active conflicts

Key indicators

US Fed Funds Rate3.50~3.75% ―The policy rate itself remains on hold at 3.50–3.75%, but bets on a hike have hardened sharply ahead of the 15-16 September FOMC. After Chair Kevin Warsh's hawkish Jackson Hole speech on 28 August, the CME FedWatch probability of a September hike rose from about 50% on 28 August and 57% on 30 August to 65.9-66% at the 31 August close. The oil surge on 31 August stoked renewed inflation worries and pushed the probability higher still. Sources differ slightly, with 62% (vistapglobal intraday tally), 65.9% (Edaily, CME FedWatch) and 66% (Forbes), but converge in the mid-to-high 60s. A 25bp hike is the base case, which would take the rate to 3.75–4.00%. A Treasury-versus-Fed standoff, with Treasury Secretary Bessent's expanded long-dated buyback (larger per-operation size from 9 September) colliding head-on with Warsh's hawkish Fed, has emerged as the market's biggest variable.
S&P 5007,686.14 ▼The Monday 31 August regular-session close was 7,686.14, down 25.62 points (-0.33%). The Dow fell 374.09 points (-0.70%) to 53,185.90, the biggest drop of the three major indices, and the Russell 2000 closed at 2,956.45 (-0.54%). The decline was driven by renewed inflation and rate-hike worries as oil jumped after a US strike on Iran's Larak Island. For the month, however, the S&P 500 finished August up 2.6%, and the Dow logged a fifth straight monthly gain. By sector, energy (Chevron, Halliburton, Exxon Mobil) and defensive stocks held up best, while materials and industrials lagged most. Among individual stocks, Edison International plunged more than 22% after wildfire-liability legislation failed, Tesla rose about 5% and Ulta Beauty about 4%. Apple CEO Tim Cook's resignation announcement was also a talking point during the session. Four sources, AP, Motley Fool, Edaily and vistapglobal, reported the same figures.
Nasdaq Composite26,370.89 ▼The index closed at 26,370.89 on 31 August (Mon), down 31.53 points (-0.12%), the smallest loss of the three major indexes. Despite the bad news of surging oil prices and rising yields, tech stocks held up relatively well and showed resilience against the old economy (Dow -0.70%), and the index finished August higher for the month on strong tech earnings. AP, Motley Fool, Edaily and vistapglobal all reported 26,370.89, so it is judged final. However, versus the previous close (28 August, 26,450.59) it is down 79.7 points, which does not match the 31.53 loss in the articles. This appears to stem from some outlets using a different prior-day close, though the four sources agree on the closing figure itself. Meanwhile, 24/7 Wall St. gave the Nasdaq Composite as 10,029.48, which is clearly a typo and was excluded.
US 10-Year Yield4.76% ▲As of the 31 August close, the 10-year Treasury yield rose about 4bp to 4.76%, the highest since January 2025. Higher inflation expectations from the oil surge and stronger bets on a September FOMC hike both played a part. The 30-year hit 5.31-5.33% in mid-August, a 19-year high, then fell briefly after Treasury Secretary Bessent announced an expanded buyback to support long-dated liquidity (19 August), and has since retraced. The Treasury formally announced that from 9 September it would raise the long-dated nominal Treasury buyback to about $4 billion per operation; the market reads this as a de facto attempt at yield-curve control by the fiscal authority and is wary of a clash with a hawkish Fed. Motley Fool and Edaily both report 4.76%.
VIX Volatility Index14.92 ▲Sources conflict. vistapglobal's 31 August daily market summary reported a close of 14.92 (+3.39%), while the Yahoo Finance live blog showed an intraday 15.28 (+5.89%). The Yahoo figure appears to be an intraday value from around the open, and 14.92 is more reliable as a closing figure. Either way it is up from the previous close (14.55 on 28 August), and despite the resumption of US-Iran armed clashes and bets on a September rate hike, the absolute level remains in a low zone of around 15. In other words, the stock market is digesting geopolitical risk only through the oil-price and interest-rate channels and is not pricing it as a systemic risk. Oil volatility (OVX) and cross-asset commodity volatility are reported to have spiked separately, however, so this is an asymmetric phase in which only equity volatility is low.
Crude Oil (WTI / Brent)~$85.8/$90.5 ▲The confirmed 31 August close, the main item to watch this week, was $85.76 a barrel for WTI (+2.83%) and $90.49 for Brent (+2.71%). Each is up about $2.5 from the previous close (28 August) of $83.3 / $88.6. The trigger was the 30 August US strike on two Iranian rocket launchers on Larak Island in the Strait of Hormuz, which the US said was an operation to stop Iran from laying mines in the strait. It is the first publicly confirmed direct engagement between the two countries since late July. Intraday, WTI rose as high as $86.22 and Brent $91.09 (each +3.4%), with Brent breaking above $90 before easing slightly at the close. So ‘Brent above $90’ is true but on an intraday-high basis; the close of $90.49 only just held the $90 level. Motley Fool’s statement that ‘WTI topped $90’ is judged to be a mix-up with Brent.
Gold~$4,466/oz ▼On 31 August, gold fell 0.64% to about $4,466 an ounce. Rio Times cited $4,461 and Motley Fool $4,466 on December futures, so the two sources are close; intraday it slid to $4,445.6 (-1.86%) by TASS's tally, falling below $4,450 for the first time since 19 August before recovering. Geopolitical conflict is normally bullish for gold, but this time it moved the opposite way, because the chain of surging oil prices, inflation worries, stronger Fed hike bets and higher real yields raised the opportunity cost of holding the non-yielding asset. Silver also fell, to around $65.6 an ounce. That is about $60 below the previous value of $4,527 and almost 5% off the mid-August peak of $4,690. Even so, gold is still up 9.3% on a month earlier and 30.6% on a year earlier, so the medium-term uptrend remains intact.
Bitcoin~$78,600 ―Bitcoin finished 31 August moving sideways in a $78,500-78,700 range. News.bitcoin.com reported about $78,600 and Nexo about $78,700 (+0.31%), so the two sources are close. It plunged to $77,024 intraday on news of US-Iran clashes but recovered the loss within 30 minutes on strong dip-buying. It gained about 24-25% in August, its best month since 2017, and its year-to-date loss narrowed from -30% at the end of July to the -10% range. Market capitalisation is $1.57 trillion. However, US spot Bitcoin ETFs saw net outflows of $201.8 million on 28 August, ending a nine-session streak of inflows, and total assets under management fell back below $100 billion, a drag. Ether is at about $2,448 (+1.74%), up 30% in August. Market attention appears to be shifting from geopolitics to the September FOMC and global liquidity.
KRW/USD₩1,368.6 ▼The Seoul FX market's daytime close (3:30pm) on 31 August (Mon) was ₩1,368.6 per dollar, down ₩3.9 from the previous session (a stronger won). More than four Korean outlets, including Money Today, Asia Economy, Seoul Economic Daily and Business Korea, reported the same figure, so it is confirmed. It is the first close in the ₩1,360s in 13 months. The distinctive feature is that the won strengthened on its own even as the dollar was broadly stronger after hawkish remarks from Fed Chair Warsh; a cumulative trade surplus from strong chip exports and foreign investors turning net buyers of Korean stocks (late in the session) tilted the balance towards dollar selling. Over August the won rose from ₩1,418 to ₩1,368.6, a fall of about ₩50 (3.5%) in the dollar rate, the strongest performance among Asian currencies.
JPY/USD¥159.6 ▼At the New York FX market close on 31 August, the dollar was at 159.60 yen, ending at the bottom of an intraday range of 159.60-159.90 (slightly stronger yen). That is about 0.6 yen stronger than the previous value of 160.2. Early on, higher oil prices from the escalating US-Iran clashes supported dollar buying, but after Treasury Secretary Bessent's remarks, expectations of further rate hikes came to the fore and yen buying instead prevailed, according to Fisco. The euro rose against the yen to close in a 185.20-185.64 range. The Japanese 10-year yield rose to around 2.95%, near the psychological 3% resistance, and the possibility of another hike at the BOJ meeting on 17-18 September limits the yen's downside. Wariness of verbal intervention by the Ministry of Finance near 160 yen also remains. The US Dallas Fed manufacturing index for August came in at 11.6, well above the 1.6 expected.
EUR/USD1.1621 ▲At the New York close on 31 August, EUR/USD ended at $1.1621, at the top of its 1.1591–1.1621 intraday range. That is little changed from the previous 1.164, a sideways range. Germany's August consumer prices, released on 31 August, rose 2.9% year on year (also 2.9% on the HICP measure), slightly below the market forecast of 3.0%, while France's preliminary August CPI rose 2.4% (HICP +2.7%), in line with expectations. Euro selling dominated early because German inflation did not accelerate as much as expected, but the move was ultimately reversed as upward pressure on eurozone prices from the surge in oil and expectations of an ECB hike revived. The ECB held rates at its July meeting, and its next meeting is on 9–10 September. The biggest event is the preliminary eurozone August HICP due on 1 September, which, given the German and French results, is expected to stay within the low-to-mid 2% range.
KOSPI6,820.02 ▲The KOSPI closed Monday 31 August at 6,820.02, up 31.14 points (+0.46%), in a dramatic reversal. Hawkish comments from Fed Chair Warsh and the resumption of US-Iran clashes sent it down more than 3% early in the session, to around 6,600, but it erased all of the losses in the afternoon and turned higher. Individuals net bought ₩310.3 billion to hold up the index; foreigners started as net sellers of ₩233.6 billion but eased their selling later, and institutions swung from net selling of ₩136.4 billion to net buying. Samsung Electronics jumped on HBM4 mass-production momentum and reports of better yields, pulling the index higher (LS Securities raised its target price to ₩450,000), while SK Hynix slid as low as ₩1,626,000 (-1.63%) intraday before narrowing its loss. LG Energy Solution rose 1.49%, Samsung Biologics 1.82% and Hyundai Motor 1.0%. The KOSDAQ fell 4.12 points (-0.49%) to 834.29. With provisional 1-20 August exports, due out on the morning of 1 September, up 56% year on year and semiconductors making up nearly half, a record month is likely.
