Asia FX Pauses After Big Rally as Questions Linger Over U.S.-Iran Truce

Most Asian currencies held largely steady on Thursday following sharp gains a day earlier, as traders weighed whether a recently announced U.S.-Iran ceasefire could hold amid renewed military activity in the region. The dollar eased slightly, oil rebounded, and attention shifted to upcoming U.S. inflation data for signals on Federal Reserve policy.

Key Points

  • Asian currencies held steady after strong gains as traders assessed the durability of a two-week U.S.-Iran ceasefire, affecting FX market sentiment and regional risk appetite.
  • Short-term geopolitical developments - notably Israeli strikes in Lebanon and Tehran's reported closure of the Strait of Hormuz - drove a rebound in oil prices, which can pressure oil-importing Asian economies and their currencies.
  • Investors are awaiting U.S. consumer inflation data for cues on the Federal Reserve’s policy path; central bank guidance and FX interventions (such as RBI measures) remain relevant for currency stability.

Most Asian currencies were little changed on Thursday after a pronounced rally in the previous trading session, as market participants took a more cautious stance on whether a temporary U.S.-Iran ceasefire would prove durable in the face of renewed hostilities in the Middle East.

The US Dollar Index eased about 0.1% after having dropped to a four-week low on Wednesday. US Dollar Index Futures were also down roughly 0.1% as of 00:09 ET (04:09 GMT).


Geopolitical headlines keep markets on edge

Markets were unsettled by a sharp escalation of Israeli strikes on Lebanon on Wednesday, with heavy bombardments reported against Hezbollah positions. Those attacks continued even after President Donald Trump announced a two-week U.S.-Iran ceasefire on Tuesday, producing mixed signals about whether Lebanon fell under the scope of the truce.

In reaction to the continuing violence, Iran signalled a tougher stance, saying that peace talks with the U.S. would be "unreasonable" under current conditions. Reports also indicated that Tehran had again closed the Strait of Hormuz, a critical maritime chokepoint for global oil shipments.

The initial announcement of the ceasefire had lifted risk appetite and weighed on the dollar, supporting higher-yielding Asian currencies. But uncertainty over the ceasefire's scope and ongoing military action has clouded the outlook for risk assets and FX.

As MUFG analysts observed in a note: "We continue to think that given the big gaps in expectation between different parties and not just the US, the chance of a durable ceasefire and agreement remains very narrow, and as such the risk of a flare up and continued volatility is very substantial."


Currency moves across Asia

  • The South Korean won's USD/KRW pair inched up about 0.2% on Thursday after the won had strengthened 1.2% in the prior session.
  • The Japanese yen's USD/JPY pair ticked up roughly 0.1% following a 0.7% decline on Wednesday.
  • The Indian rupee's USDINR rose around 0.3%; the rupee had strengthened 0.5% on Wednesday after the Reserve Bank of India left its key policy rate unchanged.
  • The onshore Chinese yuan's USD/CNY pair moved up about 0.1% after hitting a three-year low in the previous session.
  • The Australian dollar (AUD/USD) and the Singapore dollar (USD/SGD) were largely flat in early trading.

The Reserve Bank of India reiterated its intent to curb excessive volatility in the rupee and described recent foreign exchange measures as temporary.


Oil rebound adds pressure on importers

Oil prices bounced back by more than 2% on Thursday after a sharp decline the day before, as concerns persisted about potential supply disruptions via the Strait of Hormuz. Higher crude prices tend to weigh on oil-importing Asian economies and their currencies, adding another source of downside risk for those markets should prices continue to climb.


What markets are watching next

Investors are turning their focus to U.S. consumer inflation data due on Friday for additional clues about the Federal Reserve's policy path. With geopolitical uncertainty still prominent and energy prices sensitive to developments in the Strait of Hormuz, inflation readings may play an outsized role in guiding FX and interest rate expectations in the near term.

Risks

  • The durability of the U.S.-Iran ceasefire is uncertain amid continued military action in the region, raising the risk of renewed volatility in FX and risk assets - this affects currency markets and regional equity sentiment.
  • Reported closures or disruptions in the Strait of Hormuz threaten oil supply and have already supported a rebound in crude prices, creating downside pressure for oil-importing Asian economies and their currencies.
  • Conflicting signals about the geographic scope of the ceasefire and hardened political stances increase the probability of flare-ups, which could amplify swings in both currency and commodity markets.
