Asian currencies moved in tight ranges on Wednesday, while the US dollar paused its recent decline as traders balanced softer inflation data against rising geopolitical risks from the US–Iran standoff.
The dollar index was little changed in early Asian hours, edging up less than 0.1% after seven straight sessions of losses. The modest rebound followed the loss of some safe-haven demand earlier in the week as markets grew more confident that a fragile ceasefire in the Middle East could hold.
Fresh US producer price data for March showed overall inflation slowing more than expected, tempering concerns over persistent price pressures and easing some of the pressure on the greenback.
Softer producer prices bolster rate-cut hopes
The March US producer price index (PPI) pointed to a mixed but generally softer inflation backdrop:
- Headline PPI rose 0.5% on the month, matching February’s pace.
- Core PPI, which strips out volatile food and energy components, rose just 0.1%, well below forecasts.
- On an annual basis, producer inflation climbed to 4.0%, the highest since February 2023 but still short of market expectations of 4.6%.
The cooling in core wholesale prices has reinforced expectations that the Federal Reserve could still deliver at least one interest rate cut this year. The Fed left its benchmark rate unchanged at 3.5% to 3.75% at its last meeting, and the latest data gives it slightly more room to maneuver.
Consumer price figures have complicated the picture. Annual inflation for the 12 months to March rose to 3.3%, driven largely by a 12.5% surge in energy costs linked to the conflict in the Middle East.
US Treasury Secretary and former Fed Chair Janet Yellen said a rate cut this year “remains possible,” even as she highlighted ongoing inflation risks and uncertainty over the economic fallout from the conflict.
Naval blockade of Iran tightens energy squeeze
Geopolitics remains a key driver for currency and commodity markets.
The US military said its naval blockade of Iran is now fully implemented, effectively shutting down trade to and from the country and removing an estimated 1.5 million to 2 million barrels of oil per day from global supply.
US officials estimate the move is inflicting about $13 billion in monthly economic damage on Iran and adding fresh strain to global energy supply chains. Oil prices have stayed under upward pressure as traders assess the risk of prolonged disruption in a critical shipping corridor.
Despite the escalation, a tentative two-week ceasefire has so far held. US President Donald Trump said further talks between US and Iranian representatives were expected within two days and expressed confidence that the conflict could “soon draw to a close,” supporting a cautious sense of relief in risk assets.
Yuan flat ahead of China GDP, yen near multi-year lows
Across Asia, currency moves were modest and closely tied to domestic data and central bank signals.
- China: The onshore yuan was broadly unchanged as markets waited for first-quarter GDP figures due Thursday. Growth is expected to firm to around 4.8% year-on-year after a sluggish final quarter of 2025, providing some support for the currency if confirmed.
- Japan: The yen weakened slightly, with USD/JPY up about 0.1% and hovering near a one-and-a-half-year low. The currency remains under pressure from wide rate differentials between the Bank of Japan and major peers, keeping the pair near levels that heighten the risk of official commentary or intervention signals.
South Korean won steady on hawkish tone, export strength
The South Korean won traded largely flat after Shin Hyun-song, nominee to head the Bank of Korea, told lawmakers that persistent price pressures and currency weakness could justify a firmer monetary stance in the months ahead.
March trade figures beat expectations, with exports boosted by strong demand for semiconductors tied to artificial intelligence production. The robust tech cycle has provided a buffer for the won, even as external risks and higher energy prices weigh on the broader outlook.
Australian dollar climbs, rupee softens, Singapore dollar firm
Other regional currencies showed a mixed performance:
- Australia: The Australian dollar gained around 0.3%, extending a move that has taken it to a five-week high near US$0.71. The currency has benefited from hopes of a US–Iran de-escalation and relatively resilient commodity demand, even as domestic business confidence has weakened under the weight of higher energy costs.
- India: The Indian rupee slipped about 0.1% after consumer price data indicated inflation slowed in March, easing some pressure on the Reserve Bank of India to tighten further. Softer inflation, combined with global risk jitters, left the rupee marginally weaker on the day.
- Singapore: The Singapore dollar was little changed after the Monetary Authority of Singapore made a modest tightening move on Tuesday, slightly increasing the rate of appreciation of its policy band. The step was aimed at countering rising inflation driven by imported energy costs linked to the Middle East conflict.
Traders weigh easing inflation against conflict risks
The combination of moderating US core inflation and an entrenched geopolitical shock has created a cautious environment across global markets.
Traders are now pricing in a higher probability that the Fed will cut rates only once this year, rather than embark on a deeper easing cycle, as energy-driven price pressures offset some of the disinflation seen in core measures.
In Asia, currencies are tracking a fine balance between domestic fundamentals — such as China’s growth outlook and South Korea’s export cycle — and external shocks, particularly the risk of further disruption to oil supplies.
With the US–Iran ceasefire still fragile and naval operations fully in place, the potential for sudden shifts in risk appetite remains high, keeping traders focused on incoming data and diplomatic signals in the weeks ahead.
