TOKYO — The fragile pause between the US and Iran has collapsed, and Asia is already feeling the fallout. What had been described as a temporary reprieve around the Strait of Hormuz has given way to renewed instability, exposing the region to a familiar set of economic shocks: rising energy costs, tighter financial conditions and volatile currencies.
Investors had been braced for a possible second wave of disruption. But President Donald Trump’s decision to abandon the ceasefire confirmed what many had long suspected: the “peace deal” was fragile and could unravel quickly. Markets had been conditioned to expect cycles of escalation and de-escalation; this time, the consequences may run deeper.
Oxford Economics’ chief global economist Ryan Sweet warns the break in calm could be more than a roadside bump. If the truce collapses decisively, the effects will reverberate beyond oil: Asian AI supply chains could face fresh pressure, central banks may be forced into hawkish policy, credit conditions could tighten and political dynamics — including US midterms — could shift. In short, the cascade of impacts would be fast and wide.
Asia sits directly in that cascade. China’s demand-driven slowdown and persistent supply-chain strains make it more vulnerable to an external shock. Japan is wrestling with a tricky mix of stagnating growth and inflation far above the Bank of Japan’s forecasts. South Korea, which imports roughly 70% of its oil from the Middle East, is exposed to disruptions in logistics and higher energy bills. India’s rupee has slid to record lows as markets punish persistent twin deficits, while Indonesia is battling a wave of speculative pressure on the rupiah reminiscent of the late 1990s crisis. The Philippines is intervening to support the peso even amid domestic political turmoil tied to an impeachment process involving its vice president.
Control of the Strait of Hormuz remains the thorniest issue. Eurasia Group’s Ian Bremmer notes Washington demands free navigation while Tehran retains the ability to assert influence over the waterway. Neither side appears eager to return to full-scale war, but whether strategic restraint holds is an open question — and one that markets are watching closely.
The IMF has already adjusted its forecast higher. It raised its 2026 headline inflation projection to 4.7%, reflecting energy prices that, as of late February, were roughly 25% above pre-war levels. If the Middle East tilts back toward broader conflict, those numbers could prove conservative.
Complicating matters is the paradox in safe-haven flows. Asian central banks have been accumulating gold — a long-term hedge against geopolitical and currency risks — yet the metal’s price has plunged sharply from January’s record. The People’s Bank of China bought 15 tonnes in June alone, marking its largest monthly addition this year and continuing a long buying streak. Still, spot gold sits near $4,100 an ounce, more than 20% below its January peak. Part of that fall reflects renewed Fed hawkishness.
The World Gold Council’s central bank survey shows a broad institutional intent to keep adding to reserves: roughly nine in ten surveyed monetary authorities expect their gold holdings to rise over the next year, and about 45% plan to expand their own allocations. Commodities analysts point out that as oil producers refill coffers, some of that capital may flow into gold rather than US Treasuries — a pattern that feeds long-term de-dollarization trends.
Yet the dollar itself has been unusually resilient. A hawkish tilt at the Federal Reserve has reinforced greenback strength even as Washington confronts rising debt and geopolitical risk. New Fed chair Kevin Warsh, handpicked by the administration as a rate-cutter alternative, found his room for maneuver constrained after an unexpectedly hot May inflation print of 4.2% year-on-year (up from 3.8% in April). The June FOMC meeting signaled a willingness to consider further tightening rather than cuts, which has kept dollar demand high.
That dynamic has complicated Asian policy choices. A stronger dollar raises the local-currency cost of oil and other commodities, pressures exchange rates, and forces regional central banks to consider rate hikes they can scarcely afford politically or economically. Commonwealth Bank of Australia economist Carol Kong notes that a drawn-out conflict will likely sustain higher oil prices and a stronger dollar, penalizing net energy importers such as Japan and the eurozone.
At the same time, private wealth managers and family offices are increasingly wary of dollar exposure for longer-term reasons: geopolitical friction, global debt levels and interest-rate uncertainty. UBS reports growing interest among family offices in diversification strategies, including multishoring and altered asset allocations designed to build resilience to persistent and interconnected risks.
Market strategists describe the dollar’s re-emergence as brutal for Asian assets. Stephen Innes of SPI Asset Management says the “King Dollar” is back, behaving like a wrecking ball across regional FX, equities and gold. Investors can no longer assume the Fed will act as a steadying force to flood liquidity when risk assets wobble; even modest prospective hikes keep the dollar bid.
The immediate fallout is visible across Asia’s currency and equity markets. The yen, rupee, rupiah, peso and baht have all come under pressure, prompting daily intervention watchlists from Tokyo to Jakarta. Governments have limited fiscal room after the pandemic, and many central banks face the unenviable choice of hiking rates to defend currencies at the expense of fragile domestic demand.
The timing is particularly painful given the AI-driven equity boom in parts of Asia. Valuations have surged: the Kospi is up dramatically year-to-date, Taiwan’s market has rallied strongly, and major chipmakers have raised capital in the U.S. at valuations that amplify exposure to sudden shifts in risk appetite. That same froth leaves markets vulnerable to abrupt reversals when geopolitical and monetary shocks intersect.
Uncertainty is the most destabilizing factor. When asked recently about the conflict’s trajectory, President Trump answered “I don’t know,” a phrase that underscores how little clarity regional policymakers and markets have about what comes next. With limited fiscal buffers and central banks stretched between defending currencies and supporting growth, Asia’s economies face a bumpy second half of 2026.
Asia had hoped for steadier seas. Instead, the collapse of the ceasefire has returned the region to the blast zone — where energy, geopolitics and monetary policy intersect to test the resilience of economies and markets alike.
