World trends

War & Conflict

Between 20 and 23 August, the global conflict landscape is marked by simultaneously intensifying military and economic pressure centred on the Middle East. The US imposed its largest sanctions ever on Iran and re-designated Hezbollah as linked to the Iranian government, and in the Strait of Hormuz, CENTCOM claims "complete control" while running undisclosed night-time tanker escorts, which suggests a war of attrition built around blockades and sanctions rather than a head-on clash between major powers. In Gaza and Lebanon, "ceasefire" survives in name only, with sporadic strikes and casualties continuing, and in Lebanon the June agreement has all but collapsed. In Yemen, a rising frequency of Houthi attacks on mainland Saudi Arabia and the Red Sea is shaking the approach of avoiding full-scale war that has held since 2022. In Africa, fighting widened or at least showed signs of intensifying over August in all four of Sudan, the Sahel, the Democratic Republic of the Congo and Ethiopia, confirming the continent as the region with the most active wars in the world. In particular, El Obeid in Sudan and eastern Congo present a paradox: despite international mediation efforts (the Geneva JSCM meeting, MONUSCO reconnaissance), fighting on the ground is actually increasing. In Asia, Myanmar's resistance forces have shifted from defence to offence and are widening local advantages, while Afghanistan-Pakistan remains in a fragile ceasefire. Haiti remains in a chronic crisis with state functions effectively paralysed and the gang coalition's control hardening. Venezuela has moved past the large-scale military operations that followed Maduro's arrest into political transition and reconstruction, but recovery is slow, compounded by earthquake damage. The Taiwan Strait remains frozen with no actual military clash, but Taiwan's largest-ever defence budget shows that cross-strait tension keeps accumulating at the budgetary and political level. Overall, this period is characterised not by "the outbreak of new wars" but by "fine readjustment of the intensity of each of the existing 14 conflicts," with few cases that would justify reclassifying a conflict as a clear ceasefire or an escalation.

Geopolitics & Diplomacy

The biggest upset of the last week of August is the actual outbreak of the US-Canada tariff war. Despite Trump's announcement of a "deal" on 19 August and a three-day reprieve, differences over steel, aluminium, autos and lumber were never narrowed; the midnight Eastern Time deadline on 21 August passed, and 50% tariffs on Canada actually took effect in the early hours of 22 August. Canadian Prime Minister Carney immediately promised "dollar for dollar" retaliatory tariffs, and with no further talks scheduled, North American free-trade relations have entered a cooling-off period. This goes beyond simple bilateral friction, casting doubt on the credibility and predictability of Trump's second-term tariff policy itself, and sends other trading partners a warning that a tariff reprieve does not mean a deal is done. Indeed, the breakdown came just three days after the reprieve was announced, suggesting that Trump's pattern of last-minute, deadline-driven bargaining is likely to be repeated.

In the Middle East, the maximum-pressure campaign against Iran has entered a new stage. After the 60-day MOU expired (17-18 August), Vice President Vance's declaration of a "new phase of economic pressure" and Treasury Secretary Bessent's preview of "the largest sanctions and blockade in history" followed, but the details were postponed to Monday 24 August, so only rhetorical pressure rose over the weekend. With the UAE having already halted all trade with Iran on 19 August, the US asked China to cooperate as well, but Beijing is reluctant, saying sanctions alone are not a solution. Bessent is paradoxically arguing that maximum economic pressure lowers the chance of a return to military conflict, so the real front appears to be shifting from military action to financial and energy sanctions. Saudi Arabia, meanwhile, is urging dialogue first in an attempt to keep a balance, and Egypt is acting as a regional buffer, calling for the normalisation of the Strait of Hormuz and a resumption of US-Iran talks.

Northeast Asia again showed the paradox that scaling back drills invites provocation. After Trump's conciliatory gesture towards North Korea, the joint US-South Korea Ulchi Freedom Shield (UFS) exercise was cut from 11 days to 5 and ended on 21 August, yet North Korea fired about 10 short-range ballistic missiles right afterwards (20 August). Kim Yo Jong denounced the decision to scale back the drills itself as a 'disaster of an unrealistic view of security' and reaffirmed Pyongyang's distrust of Washington. Meanwhile, South Korea's discussion of wartime operational control (OPCON) transfer continues, aiming to set a timeline at the US-South Korea security consultations in October, putting the balance between shifting the security posture and deterring North Korea to the test. At the same time, China's rare-earth (dysprosium and terbium) exports to Japan have effectively fallen to 'zero', deepening a supply-chain crisis for Japan's defence and semiconductor industries, while a dispute between Russia and Japan over the Kuril Islands escalated to the summoning of an ambassador after hawkish remarks by Prime Minister Takaichi. US-China relations show a dual pattern: Xi Jinping's White House visit on 24 September is confirmed, so the summit channel stays open despite the tensions.

Western backlash over Israel's E1 settlement expansion is escalating into discussion of concrete sanctions. After the UK, France, Germany, Italy and others warned their companies against bidding, the EU is reportedly weighing a package covering labelling of all Israeli products, reduced academic exchanges and scaled-back security and diplomatic ties (20 August). The measures would go beyond the EU's long-held principle of distinguishing between Israel and the settlements and, if adopted, would mark a qualitative change in European-Israeli relations. Israeli Foreign Minister Saar and the far right rejected the move head-on and made clear they have no intention of backing down; the issue is likely to become a domestic political flashpoint ahead of the general election scheduled for 27 October. In the Arab world, meanwhile, Egypt, Qatar, Kuwait and others continue to weigh whether to join the Mecca joint defence pact among Saudi Arabia, Turkey and Pakistan, while Turkey, with the integration of Syria's Kurdish forces into Damascus complete (21 August), has shed one border-security burden and is seeking to widen its regional influence.

In Europe, the lull in the Russia-Ukraine war continued, but subtle signs of a possible restart emerged. Russian Deputy Foreign Minister Ryabkov said on 21 August that Moscow is open to 'reasonable proposals that match Putin's goals', leaving room for a renewed Trump administration mediation effort, but Russia's existing demands remain unchanged: cession of the Donbas, demilitarisation and renunciation of NATO membership. Germany continues to study a NATO-style security guarantee for the post-war period, while Poland, scrambling fighter jets almost constantly in response to Russian air-raid alerts over Ukraine, is bearing a mounting burden as a frontline state. With Washington putting its policy priorities on the tariff war with Canada and sanctions on Iran rather than European defence, anxiety in Europe about US security commitments could potentially grow.

Significant changes were also seen elsewhere. In Venezuela, former President Maduro was taken into US custody in January and brought to trial, and the acting administration of Delcy Rodriguez has won formal US recognition, so normalisation, including reopening embassies, resuming direct flights and restarting oil sales, is now well advanced. Nigeria is managing its relationship with the US, despite being redesignated a 'country of particular concern', through a security cooperation meeting (12-13 August) and eased shipping restrictions (18 August). In Brazil, six weeks before the 4 October election, a close race between Lula and Flavio Bolsonaro has emerged as a variable that could shape South America's political landscape. Denmark, as Trump repeatedly says he will 'secure Greenland before 2029', has won the involvement of European allies through Dutch and NATO troops joining exercises, and India continues its balancing diplomacy between the US and China ahead of the BRICS summit in September.

Finance & Economy

The biggest event for global financial markets is the Jackson Hole symposium on 27-29 August and new Fed Chair Kevin Warsh's debut speech. With the probability of a September hike having plunged from 60% to 33% after the July jobs shock, whether Warsh leans hawkish or dovish is the focus of intense interest. With inflation at 3.4%, above target, the policy dilemma between slowing employment and prices is deepening. August jobs and CPI data will be released between Jackson Hole and the 16 September FOMC and are expected to influence the final judgment. The market is likely to take this speech as the first signal of a change in the monetary policy framework.

The surge in long-dated US Treasury yields has emerged as a key variable across the market. The 30-year yield jumped to 5.276% (5.31% intraday), the highest since 2007, and total federal debt topped $40 trillion. Even though Treasury Secretary Bessent doubled the size of long-dated buybacks, yields were pushed back up within a day, exposing the limits of the policy's effect. This led to a weekly decline in the S&P 500 (the first weekly fall since the end of July) and is adding to the market's structural worries about fiscal soundness. Remarks at Jackson Hole and future Treasury issuance plans could be catalysts for further volatility.

Geopolitical risk is shaking commodity markets. US-Iran military tension and the diplomatic deadlock in the Gulf lifted Brent to the $93s a barrel, up for a second straight week. With Treasury Secretary Bessent's "maximum intensity" sanctions on Iran due to be announced on 24 August, and pressure on allies and China running in parallel, market tension is high. Gold also hit a three-month high of $4,600-4,680 an ounce, showing clear safe-haven demand. Oil price swings have a direct fiscal and current-account impact on both producers and importers such as India and Saudi Arabia.

Bitcoin posted its biggest weekly gain in two years and settled in the $77,000s, touching $79,500 intraday. Even in a risk-off environment of surging Treasury yields and fiscal worries, an unusual decoupling appeared in which risk appetite revived. Spot Bitcoin ETFs took in more than $600 million in a day and Ethereum ETFs more than $200 million, backing institutional inflows. However, the altcoin season index remains at 33 out of 100, so it is assessed that a full-scale rotation phase has not yet arrived. Because it trades around the clock, volatility tied to Jackson Hole expectations and Iran risk is expected to continue over the weekend.

Asian currency and rate markets are showing mixed signals. Japan's 10-year government bond yield hit 2.945%, a 30-year high, reflecting expectations of a further BOJ hike in September, while the won fell to an 11-month low against the dollar (a stronger won), pricing in advance the expected hawkish hold at the Bank of Korea meeting on 27 August. China held its LPR for a 15th month, showing a contrasting continuation of a cautious easing stance. The decoupling of the KOSPI and KOSDAQ (+0.88% vs -4.63%) shows concentration in large-cap and export stocks. The decoupling of monetary policy across the region could be a main background to currency volatility next week.

Emerging markets are pursuing monetary policy at different speeds. Brazil cut its Selic rate for a fourth straight time on slowing inflation, and Turkey cut to 37% by a smaller-than-expected margin, taking a cautious approach to pacing. Argentina has sharply lowered inflation through Milei-style austerity, but signs of cracks in its recent economic model have also been raised. Russia-Ukraine peace talks remain deadlocked, with Western sanctions and strong oil prices both having an effect. In Europe, Germany's stalled growth and France's fiscal and political instability are cited as factors raising the risk premium across the eurozone.

Tech & Energy

Market attention is focused as Nvidia's 26 August earnings are three days away. The gap between the company's guidance ($91 billion, ±2%) and the consensus ($91.9 billion) has narrowed to only about $1 billion, and the mood is largely optimistic, with EPS estimates revised up for four straight quarters. However, the guidance still assumes zero China data-centre revenue, and the company's official denial, six days before the report, of reports of low-end chip shipments to China show that uncertainty over China sales has not been resolved. The market's focus is less on total revenue than on whether the non-GAAP gross margin holds at 75% and how much sequential growth in the data-centre segment slows. It is also worth noting that PJM put forward a draft rule on 17 August to curtail new large loads of 50MW or more first, making power interconnection itself the next bottleneck for AI data centres.

Two opposing trends are under way at once in the memory chip market. On one hand, Samsung Electronics (39%), SK Hynix (26%) and Micron (25%) still hold 90% of the DRAM market and are enjoying the supercycle, with first-half memory revenue up 305% from a year earlier. On the other, China's CXMT is catching up fast, growing 716% year on year, and completed a Shanghai listing at the end of July. Importantly, the two trends are not mutually exclusive: with the whole pie expanding rapidly on AI demand, Chinese domestic substitution has not directly translated into lost sales for South Korean and US makers. Still, criticism continues that SK Hynix's fixed-price HBM4 long-term contracts may limit its gains in an upswing, so it bears watching whether a gap opens up in future pricing power.

US semiconductor controls on China are moving on a ‘dual track’. One track is an easing one, in which items already permitted, such as the H200, are imported in small amounts (13% of the quota) through case-by-case approval by China's National Development and Reform Commission (NDRC). The other is a hardline track, in which the MATCH Act, which seeks to ban sales and maintenance of ASML's older DUV equipment outright, is being folded into the defence budget bill. Given that the bipartisan-backed defence budget is likely to pass despite lobbying by the Dutch government, the cut in ASML's China revenue share from 33% in 2025 to the 20% range in 2026 is increasingly seen as a foregone conclusion. In effect, opposing policies are running in parallel: tightly controlled small-scale opening for advanced logic (Nvidia GPUs) and a tighter blockade on core equipment technology (ASML).

In the Middle East, the US-Iran standoff over the Strait of Hormuz entered a prolonged phase after the negotiating deadline passed on 16 August. Physical clashes continue, with UAE ADNOC tankers attacked on 8 and 14 August, but according to Al Jazeera's analysis of ship tracks from 1-19 August, oil is at about $92.9, below the March peak of $119 a barrel, making it hard to say flatly that prices are stuck above $100. Moreover, with about 20% of oil tankers openly using Iran-designated routes, some interpret the market as reflecting Iran's control more than the US in terms of the blockade's effectiveness. Despite these risks, the UAE said on the 6th, through Mubadala, that it is considering a $6.3 billion AI data-centre investment in Akita, Japan, showing Middle Eastern capital continuing to bet on AI infrastructure while spreading regional risk.

Russia's fuel shortage is resurging to the point that on 15 August the government itself acknowledged a ‘supply strain’. Ukrainian strikes on refineries are dragging on, as in the case of the Orsk refinery, now in its sixth month, and rationing-style measures (purchase limits, a ban on filling canisters) have been confirmed in multiple regions. It shows Russia's crude and refined-product supply chain suffering the double blow of sweeping sanctions and physical attacks, and doubts about Russia's reliability as a supplier may keep arising in international energy markets.

Competition between nations over capital and technology for AI infrastructure is diversifying beyond a US-China duopoly. Taiwan continues the ‘de-China, pro-US’ relocation of advanced foundry capacity through TSMC's additional Arizona investment ($100 billion, $265 billion cumulative), while Japan is strengthening its standing as a recipient of investment through the Akita data centre backed by UAE capital, alongside Rapidus's national 2-nanometre project. India is preparing for the opening of Semicon India 2026 on 17 September, but most of the sites approved so far remain at the assembly and packaging (OSAT) stage, prompting a sober assessment that self-reliance spanning design, materials and equipment will take longer. France attracted €75 billion from SoftBank on the strength of surplus nuclear power, but the new EPR2 reactors are not due until 2038, so in the short term it depends on existing nuclear assets. Saudi Arabia is extending beyond data centres through HUMAIN to consumer devices, with an AI laptop teased on 20 August. Countries are plainly entering the AI supremacy race with different comparative advantages: manufacturing, capital, energy and policy drive.

Active conflicts

Key indicators

US Fed Funds Rate3.50~3.75% ―Maintained after the August hold, with new Fed Chair Kevin Warsh set to give his first public speech since taking office at the Jackson Hole symposium on 27-29 August (scheduled for around 10am local time on the 28th). July nonfarm payrolls fell 23,000, and the probability of a September hike plunged from 60% at one point to about 33% (one-third). Inflation at 3.4% is still above the 2% target, so the tension between a weakening labour market and prices persists. August jobs and CPI data will also be released between Jackson Hole and the 16 September FOMC and are expected to influence the final decision. Note: 22-23 August is a weekend closure, so this is the value as of the Friday 21 August close.
S&P 5007,674.37 ―On Friday 21 August the S&P 500 closed up 0.43% (+33.21 points), a figure cross-checked across multiple sources including AP and Yahoo Finance. Markets are closed on the weekend of 22-23 August, so this close stands. For the week, however, it fell 1.4% on the fallout from surging Treasury yields, its first weekly decline since late July. The Jackson Hole symposium and Nvidia's earnings next week are awaiting as sources of volatility.
Nasdaq Composite26,180.46 ―The index closed up 0.43% (+113.29 points) on 21 August, cross-checked against AP and Yahoo. With markets closed for the weekend, this close stands. For the week, tech stocks led the weakness as Treasury volatility weighed. Chair Warsh's remarks and big tech earnings next week will determine direction.
US 10-Year Yield~4.74% ―Based on the 21 August close, the 10-year was 4.737%, and amid this week's Treasury sell-off the 30-year surged to 5.276% (5.31% intraday, the highest since 2007). Treasury Secretary Bessent doubled the long-dated buyback from $2 billion to at least $4 billion per operation, but it was reversed within a day. Total federal debt has topped $40 trillion, and upward pressure on the term premium continues. The weekend closure keeps the 21 August level, with Warsh's Jackson Hole speech the next variable.
VIX Volatility Index15.08 ―The 21 August close differs slightly by source, from 15.08 to 15.13 (Yahoo Finance 15.13, -5.5% on the day), but is cross-checked at just over 15. It jumped to around 16 early in the week on Iran-related tensions before dropping sharply in Friday's relief rally. The weekend market closure keeps this level. A renewed rise in short-term volatility remains possible ahead of the Jackson Hole event.
Crude Oil (WTI / Brent)~$86.8/$93.8 ―Based on the 21 August (Fri) close, WTI is about $86.8 a barrel and Brent about $93.8. Crude futures markets are closed at weekends, so no new prices formed on 22-23 August. The supply risk premium persists as the closure of the Strait of Hormuz drags on, but the rise has paused after Iran hinted at ending hostilities. The further Iran sanctions that Treasury Secretary Bessent said would be announced on 24 August are the biggest variable that could reignite the premium.
Gold~$4,680/oz ―Based on the close on Friday 21 August, spot gold held at about $4,680 an ounce, the highest in three months. Precious-metals spot and futures markets were both closed over the weekend, so there was no new price formation. Hedging demand against widening fiscal deficits and currency debasement, and a weaker dollar, were behind last week's rise. New Fed Chair Kevin Warsh is due to give his debut speech at Jackson Hole on 27-29 August, and whether policy uncertainty clears is the biggest variable for gold next week.
Bitcoin~$77,400 ▲Bitcoin, which trades around the clock including weekends, rose as high as $79,500 intraday on 22-23 August, testing the $80,000 level, before slipping back to the mid-$77,000s. That continues the advance after the 21 August close of $77,064 (+6.06%), and the weekly gain is the largest since 2024. Expectations of pro-crypto regulation, including the Trump administration's push for the Clarity Act, and broad dollar weakness acted as catalysts. Note, however, that weekend liquidity is thin and volatility tends to be exaggerated.
KRW/USD₩1,386.5 ―The won stood at ₩1,386.5 per dollar as of 21 August, its sixth straight daily decline and the lowest in 11 months (a stronger won). With markets closed for the weekend, this level stands. A hawkish hold is the prevailing forecast ahead of the Bank of Korea Monetary Policy Board meeting on 27 August (some brokerages also mention the possibility of a minority dissent in favour of a hike). Uncertainty over Fed policy and the Jackson Hole event are the variables for next week's direction.
JPY/USD~¥158.9 ―As of 20 August, the dollar rebounded from the high 158s on dip-buying (the yen weakened). The Japanese 10-year yield reached 2.945%, the highest in 30 years since September 1996, and the 30-year rose to 4.115%. The market is betting on a further BOJ rate hike in September, leaving the yen's direction mixed. With markets closed for the weekend, the 21 August level stands.
EUR/USD~1.170 ―EUR/USD traded around 1.170 at the 21 August close. Dollar strength from the surge in US Treasury yields and political unrest in Europe (continuing worries about a French fiscal crisis) are capping the upside. With weekend markets closed, the level holds, and next week's remarks at Jackson Hole are expected to raise volatility in the dollar index.
KOSPI6,912.95 ―The KOSPI closed at 6,912.95, up 0.88%, on 21 August, while the KOSDAQ plunged 4.63% to 801.94 the same day, a clear decoupling between large and small caps. The close carries over the weekend market holiday, and the Bank of Korea's rate decision on 27 August is seen as next week's biggest variable. A stronger won and expectations for the chip cycle are influencing the index's direction.
