World trends

War & Conflict

The global conflict landscape in late August 2026 can be summed up as one in which fronts have multiplied but no war has ended. In the Middle East, the war between the US and Israel on one side and Iran on the other has shifted its axis from military strikes to economic pressure: on 20 August the US announced ultra-tough sanctions on Iran and a re-designation of Hezbollah and deployed a new carrier strike group, while the Strait of Hormuz entered a phase of partial management under an Iran-Oman shipping coordination plan. Gaza is nominally under a ceasefire, but killing continues, including 15 deaths in strikes on a cafe and a police station on 18-19 August, and Israel's effective control has grown from 53% to 70% since the Yellow Line, cementing the deadlock over whether disarmament or withdrawal comes first. In Lebanon, the two truces of June have effectively collapsed and deaths since March have passed 4,300, and in Yemen the 2022 truce framework has been fully broken by the government's 133 operations a day and Houthi attacks on the Red Sea and Saudi Arabia. The Ukraine front is deadlocked on the ground but at a record scale in the air, hardening into a war of attrition in which Russia fires 376 missiles and 5,000 drones a month while Ukraine strikes the Ufa refinery more than 1,000 km away and the two sides trade more than 400 drones in a single night. In Africa, Sudan's RSF is tightening its siege of El Obeid and has struck as far as Khartoum and Atbara with drones, while in the Sahel the JNIM fuel blockade has pressed Bamako for nearly a year, holding the very functioning of the state hostage. In eastern Congo, a pattern of "peace on paper" repeats, with diplomatic processes such as the Doha framework and the Geneva JSCM meeting piling up while real fighting continues in North and South Kivu. In Ethiopia, Sudan's RSF joined the fighting at Sherarina in western Tigray on 1 August and Eritrean heavy weapons moved to the Raya front, raising the risk that Sudan's civil war and the Horn of Africa fronts fuse into a single battlefield. In Haiti, UN figures show 613 people were killed in four and a half months as gang violence approaches state collapse, while the Gang Suppression Force is ineffective for lack of funds and troops. The relatively stable axes, the Afghanistan-Pakistan ceasefire and the Taiwan Strait, remain frozen, each under structural pressure: the TTP problem and the largest defence budget ever (NT$1.1225 trillion), respectively. Overall, no conflict changed intensity rating compared with 21 August; the change is showing up not in intensity but in the form of the pressure tools (sanctions, blockades, deep drone strikes).

Geopolitics & Diplomacy

The biggest shift on 21 August was the changing character of the Iran war. After the 60-day memorandum of understanding expired without extension on 17-18 August, Washington shifted its weight from a military ultimatum to an economic blockade. Vice President Vance declared that the war had entered a "new phase of economic pressure", and Treasury Secretary Bessent previewed the "largest coordinated economic isolation in history", demanding that allies choose sides. This means extending the front from the Middle East to the entire global network of finance, shipping and energy, and countries that have kept trading with Iran, such as India, China and Turkey, become immediate targets of pressure. The UAE's complete halt to trade on 19 August shows that this setup has already begun to operate inside the Gulf.

US tariff diplomacy still runs on deadline politics. Even though a "deal announcement" was made with Canada on 19 August, it had not been put in writing by 21 August, and the reprieve deadline was set for 12:01 a.m. Eastern Time on 23 August. Figures such as 15% on autos and 25% on steel and aluminium go up and down, but none has been signed, and Canadian domestic political issues such as bans on alcohol sales and exclusion from government procurement are the last bottleneck. A structural constraint on the talks is that 56% of Canadians oppose further concessions in polls, narrowing Prime Minister Carney's room to manoeuvre. The key to watching this case is not to mistake the lag between announcement and finalisation for the result.

In East Asia, an asymmetric phase is clear in which deterrence and conciliation are both strengthening. On Trump's orders, Ulchi Freedom Shield was cut from 11 days to five and ended on 21 August, with the counter-offensive phase dropped, but North Korea responded on 20 August with about 10 short-range ballistic missiles and Kim Yo Jong denied talk of contact between the leaders. On the other side, Taiwan on 20 August sent the legislature its 2027 defence budget, which for the first time exceeds 3% of GDP, moving to expand deterrence. A setup in which the US reduces allied exercises while demanding allies arm themselves is applying simultaneously to South Korea, Taiwan and Japan. President Xi Jinping's state visit to the White House on 24 September is the variable that could shake this balance again.

China is widening its axis towards ASEAN, pairing military pressure with diplomatic co-optation. On 21 August Foreign Minister Wang Yi and Defence Minister Dong Jun held the first "comprehensive strategic dialogue" with Indonesia in Jakarta, discussing defence cooperation and the South China Sea, shortly after the two navies conducted joint drills in waters east of Taiwan. The Philippines, too, amid friction in the South China Sea, has publicly mentioned the possibility of joint oil and gas development with China as it seeks a balance. ASEAN countries are increasingly trying to keep equidistance between US demands to join sanctions on Iran and China's economic and security inducements. The Taiwan Strait and the South China Sea are being reshaped into one connected space of pressure.

In Europe, the military, diplomatic and domestic dimensions of the Ukraine war are all stalled at once. US-mediated talks have not resumed since the collapse in Geneva in February, and Russia maintains its maximalist demands of ceding all of Donbas and a permanent bar on NATO membership. On top of the physical limit of a Patriot interceptor shortage, Ukraine faces domestic cracks in the form of fallout from the dismissal of Defence Minister Fedorov and a vacancy in the foreign ministry's leadership. Germany sticks to a security-guarantee framework that excludes Russia, while Poland and the three Baltic states are preparing for hybrid provocations and false-flag scenarios. With the negotiating table empty and pressure growing only at the front and in the rear, the asymmetry is likely to continue into winter.

In the Middle East and Africa, a new security bloc and a Western rift with Israel are both advancing. The Mecca joint defence pact of 7 August bound Saudi Arabia, Turkey and Pakistan, with Egypt's accession being weighed, while the Houthi drone attacks on Najran and Aramco show that this bloc is immediately being tested in practice. Meanwhile, the UK, France, Germany, Italy, the Netherlands, Canada and Norway have called Israel's E1 settlement expansion "unacceptable" and the EU is preparing a sanctions package. The Gaza roadmap has begun to be implemented with Hamas's acceptance and Israel's tightened rules of engagement, but it is fragile because Prime Minister Netanyahu denies agreeing to the disarmament plan. With Israel's 27 October general election and the UN General Assembly schedule overlapping, the next two months are expected to be a watershed for the roadmap.

Finance & Economy

The focus of the market this week was bonds, not stocks. Even though the US Treasury doubled its long-dated buybacks from $2 billion per operation to at least $4 billion, the 10-year yield was pushed back up to 4.737% and the 30-year to 5.276% on 21 August, and the 30-year hit 5.31% during the week, the highest since 2007. It was confirmed within a day that supply-side measures cannot offset the root cause, the fiscal deficit. With total federal debt above $40 trillion, long-dated yields are moving as a function of "fiscal credibility" rather than "policy tools". This is not just a US problem, and is spreading as a synchronised rise in global long-term yields, including Japan's 30-year at 4.115% and French OATs.

Signals from stocks and bonds are directly at odds. The BofA August fund manager survey showed the most aggressive positioning since November 2021, with cash at 3.5% and a net 56% overweight in global equities, and "no landing" expectations are at a record high. By contrast, a 30-year yield at 5.3% is the bond market's blatant distrust of confidence in controlling inflation. The S&P 500 rebounded 0.43% on 21 August but fell 1.4% for the week, its first weekly loss since the end of July, and that is where this rift surfaced. With positioning extremely one-sided, even a small catalyst can trigger a sharp reversal.

The fact that new Fed Chair Kevin Warsh gives his debut speech at Jackson Hole on 27-29 August is pinning down the short-term direction of every asset class. Because Chair Warsh has adopted a communication style that minimises forward guidance, the market bears the burden of interpreting the message itself rather than receiving a clear signal. The probability of a September hike has now fallen to about 34%, a December hike is priced in, and 72% of fund managers see no hike before the November midterm elections. The problem is the risk of long-dated yields being pushed up again if Chair Warsh fails to present a credible framework for dealing with prices. It is a rare phase in which monetary policy uncertainty overlaps with fiscal uncertainty.

The simultaneous surge in alternative assets reads as an indirect market vote on confidence in fiat currencies. On 21 August Bitcoin jumped 6.06% to $77,064, its biggest weekly gain in two years, and gold rose 2.38% to $4,680 an ounce, a three-month high. The regulatory catalyst of the Trump administration's push for the Clarity Act acted directly on Bitcoin, but the common logic that pushed both assets up was demand for a hedge against a widening fiscal deficit and currency debasement. Broad dollar weakness amplified it. The most unusual feature of this phase is that the status of Treasuries as a safe haven is being shaken even as Treasury yields are near record highs.

In Asia, South Korea and Japan are under currency pressure in opposite directions. The won stood at ₩1,386.5 per dollar on 21 August, down for six straight sessions and at its lowest in 11 months, the result of global dollar weakness combined with corporate dollar sales on strong chip exports and won demand tied to interim corporate tax payments. By contrast, the yen has struggled to move below the high-¥158 range and is testing the ¥160 intervention line, and Japan's 10-year yield hit 2.94%, a 30-year high. It is an asymmetry within the same dollar-weakness phase, in which fundamentals are lifting the won while the rate gap holds the yen down. The Bank of Korea's meeting on 27 August is likely to produce a hawkish hold amid this easing in the exchange-rate backdrop.

The channel by which geopolitics constrains monetary policy through prices is becoming entrenched. With the deadlock over the blockade of the Strait of Hormuz, Brent stays at $93-95 and WTI at $86-88, making the risk premium permanent, and the small decline on 21 August was closer to a temporary pullback on Iran hinting at an end to hostilities. Additional sanctions on Iran flagged by Treasury Secretary Bessent could reignite the premium at any time. India (repo rate 5.25%) and Turkey (37%), as net energy importers, absorb this burden directly in prices and the current account, and China held its August LPR for a 15th straight month, narrowing its own room for easing. Conversely, Saudi Arabia and Russia benefit on the revenue side, but logistics disruption from the blockade partly offsets this.

Tech & Energy

In late August the focus of tech supremacy converges on Nvidia's earnings. The midpoint of the quarterly guidance due on 26 August is $91 billion, up about 95% from a year earlier, but it crucially assumes zero data-centre compute revenue from China. Policy allows roughly 1 million H200 chips to be imported, but actual deliveries on 19 August amounted to only about 10,000 chips each for ByteDance and Tencent. The US-China chip relationship is thus structurally marked by a gap between legal permission and physical flows, and whether that gap narrows is the biggest upside variable for coming quarters. The market is already pricing in zero China, creating an asymmetry in which a policy change would itself be the surprise.

The front line of equipment controls has moved down from cutting-edge EUV to older DUV tools and maintenance. The US MATCH Act would ban sales of the older DUV machines now permitted and end servicing of existing equipment in China, and it is on track to be folded into the defence budget bill. The Netherlands has protested the extraterritorial reach and is lobbying in Washington, but its chances of success against bipartisan support are rated low. With the possibility of sanctions on the Netherlands for non-compliance even being raised, allied autonomy itself is now on the negotiating table. ASML's China share of revenue is expected to shrink from 33% in 2025 to around 20% in 2026, and the drop would be larger still if service revenue were cut off.

Memory is in an unusual phase in which a supercycle and a new entrant are unfolding at the same time. In the second quarter, DRAM shares were Samsung 39%, SK Hynix 26% and Micron 25%, leaving the existing big three intact, but CXMT grew 716% year on year to 7%, becoming the first meaningful fourth pole. CXMT secured funds for expansion with its 31 July listing on Shanghai's STAR Market at a market value of $544.9 billion and has pledged a 30% share by 2030. However, the bottleneck of blocked access to EUV and advanced DUV tools remains, making equipment controls the test of what actually caps Chinese DRAM. For South Korea, the dual challenge has become clear: defending margins at the top end in HBM while the bottom of the commodity DRAM market is eroded.

The downside of the HBM first-mover strategy is also emerging. SK Hynix locked in volumes by signing HBM4 long-term supply contracts early with about 10 big tech customers, but its annual fixed-price structure is said to make it hard to pass on the recent surge in memory prices. The result is a reversal in which rivals with a larger share of commodity DRAM, repriced quarterly, benefit more from the upswing. A mismatch between HBM3E price adjustments and the timing of the HBM4 transition also weighed on near-term earnings. The question to watch is whether the lesson that being first does not mean being profitable is reflected in the terms of 2027 LTA negotiations.

It has been confirmed in policy that the real constraint on AI infrastructure is not chips but power and the grid. The 60-day deadline on the large-load interconnection order that FERC passed unanimously on 18 June fell around 17 August, and tariff revisions by six grid operators including PJM have got under way. On 21 August, a proposal by PJM to designate new loads of 50MW or more as the first to be curtailed in emergencies drew attention. US data-centre power demand is expected to rise from 75.8GW in 2026 to 134.4GW in 2030, and one analysis found AI load has pushed up power costs by 60%. On the other side, France used its EDF nuclear fleet to attract €75 billion and 5GW of investment from SoftBank, while the Gulf is building a third compute pole with the 200MW first phase of Stargate UAE and Saudi HUMAIN's $9.1 billion strategy. Competition over compute locations has become competition over power mix.

On the energy side, two supply shocks of different natures coexist: the Hormuz deadlock and Russia's fuel crisis. At Hormuz, hopes of reopening were repeatedly dashed, by a draft of limited passage from Iran on 6 August, a deadlock in talks on 10-11 August and a renewed attack on 12 August, leaving Brent stuck in the $100s and Gulf-Asia VLCC freight rates at record highs of $470,000-500,000 a day. In Russia, 54% of refining capacity has been hit and 72% of petrol stations have run out of gasoline; the government has taken emergency measures, including temporarily reviving low-grade Euro-2 to Euro-4 fuel and raising imports from Belarus 25-fold. The former blocks export routes while the latter destroys refining capacity, so the responses differ, and Russia is in the paradoxical position of being an oil producer and a refined-products importer at once. The channel through which these two shocks feed back into AI data-centre costs via electricity prices is the key risk path for the second half of 2026.

Active conflicts

Key indicators

US Fed Funds Rate3.50~3.75% ―As of 21 August (local time) the federal funds target range is maintained at 3.50–3.75%. New Fed Chair Kevin Warsh makes his debut speech at the Jackson Hole symposium on 27-29 August. With July payrolls down 23,000 and consumer price inflation easing to 3.4% year on year, the probability of a September hike has fallen to about 34%, and the market is pricing a December hike. In a BofA fund manager survey, 72% said there would be no hike before the November midterms.
S&P 5007,674.37 ▲The S&P 500 closed at 7,674.37 on 21 August (local time), up 0.43% from the previous day. Since the prior session on 20 August closed at 7,641.16 (-0.9%), this was a clear rebound. For the week, however, it fell 1.4%, its first weekly decline since late July. A surge in Treasury yields and US-Iran tensions weighed on the index all week.
Nasdaq Composite26,180.46 ▲The index closed at 26,180.46 on 21 August (local time), up 0.43%. The rebound followed a 1.0% fall from 26,067.17 on 20 August and partly reversed the early-week selloff in chip stocks and the shock from bond volatility. The Dow also rose 518 points (+0.98%) to close at 53,276.81. However, all three major indexes fell at least 0.8% on the week.
US 10-Year Yield~4.74% ▲On 21 August (local time) the 10-year yield was 4.737%, still near a multi-year high. The 30-year was 5.276%, as the rally fizzled and reversed within a day even though Treasury Secretary Bessent had doubled the long-dated buyback size from $2 billion to at least $4 billion per operation. With total federal debt above $40 trillion, fiscal-deficit worries keep exerting upward pressure on long-dated yields. The 30-year also hit 5.31% during the week, the highest since 2007.
VIX Volatility Index15.08 ▼On 21 August (local time) the VIX fell 5.81% to 15.08. The previous day, 20 August, it had jumped 7.5% to 16.01 on rising US-Iran tensions. Short-term hedging demand unwound as stocks rebounded and Iran signalled willingness to end hostilities. Bond-market volatility, however, is still seen as a bigger core risk for markets than equity volatility.
Crude Oil (WTI / Brent)~$86.7/$93.6 ▼On 21 August (local time), September WTI closed slightly lower at $86.72 a barrel (-0.13%) and Brent at $93.64 (-0.15%). The supply risk premium persists as the closure of the Strait of Hormuz drags on, but the rise paused after Iran signalled willingness to end hostilities. Treasury Secretary Bessent's warning of further sanctions on Iran remains a potential risk to energy supply and inflation.
Gold~$4,680/oz ▲On 21 August (local time), spot gold jumped 2.38% to about $4,680 an ounce. Futures rose 1.44% to $4,637, the highest in three months. Hedging demand against widening fiscal deficits and currency debasement, a weaker dollar and policy uncertainty ahead of Jackson Hole all stoked buying. Silver futures, by contrast, fell 1.92% to $69.42 an ounce, showing divergence within precious metals.
Bitcoin~$77,100 ▲On 21 August (local time), Bitcoin jumped 6.06% to $77,064, breaking above $77,000. The weekly gain was the biggest since 2024, driven by expectations of pro-crypto regulation, including the Trump administration's push for the Clarity Act, and a weaker dollar. With Treasury yields elevated, the narrative of a decentralised asset outside the traditional banking and Treasury system became a buying argument.
KRW/USD~₩1,386.5 ▼At the daytime close (3:30pm) on 21 August, the won stood at ₩1,386.5 per dollar, down ₩6.1 from the previous session. It was the sixth straight daily decline and the lowest in a little over 11 months, since 17 September last year (₩1,380.1). Broad global dollar weakness was compounded by corporate dollar sales from strong chip exports and demand for won to pay interim corporate taxes. The market consensus is that the won will keep a gradual strengthening trend through year-end.
JPY/USD~¥158.9 ―In Tokyo trading on 21 August the dollar traded at 158.97 yen, then stayed in the high 158s as the dollar weakened broadly. Expectations of a further BOJ hike remain firm, supporting the yen's floor, and the Japanese 10-year yield reached 2.94%, the highest in 30 years since September 1996. The 30-year yield is 4.115% and the 2-year 1.7%, the highest since May 1995. The possibility of Japanese authorities intervening as the dollar nears 160 yen is cited as a risk factor.
EUR/USD~1.170 ▲On 21 August EUR/USD traded around 1.1696, then edged up to the 1.17 level as dollar weakness resumed. Eurozone data that came in firmer than expected fuelled euro buying and dollar selling. Uncertainty over the Fed's rate-cut path also weighed on the dollar. French fiscal and political risk, however, remains a structural cap on the euro.
KOSPI6,912.95 ▲The KOSPI closed at 6,912.95 on 21 August, up 60.37 points (+0.88%), regaining 6,900. Large-cap chipmakers such as Samsung Electronics and SK Hynix pulled the index higher, but across the market decliners outnumbered advancers three to one. The KOSDAQ, by contrast, tumbled 38.95 points (-4.63%) to 801.94, a wide gap between the two indices. The volatile phase that followed the 5.80% crash on 19 August and the sidecar-driven rebound on 20 August continues.
