Asian currencies mostly strengthen on risk-on; dollar retreats

Most Asian currencies strengthened in early trading as risk-on sentiment improved on renewed hopes for talks between the U.S. and Iran, lifting risk assets and weighing on the dollar. Investors moved back toward riskier positions amid signs that geopolitical tensions might ease, supporting regional FX.

Market moves were reflected in equity gains across the region: benchmarks such as Japan’s Nikkei and South Korea’s KOSPI rose more than 2% in some sessions and broader Asia-Pacific gauges advanced, while the dollar index slid to levels not seen in several weeks. China’s onshore yuan also firmed, reaching its strongest levels in roughly three years as sentiment improved. Those shifts highlighted a broad re-pricing of risk across asset classes.

On the FX front, USD/JPY eased and Asian local-currency pairs such as USDCNH and USDINR saw narrowing; commodity-linked currencies like AUDUSD benefited from improved risk appetite. Oil prices fell on the prospect of reduced regional supply disruption, which in turn dampened inflation concerns and provided additional support to emerging Asian currencies. These moves favored carry and spread trades while keeping intraday volatility contained in thin holiday liquidity windows.

The broader backdrop remains geopolitical: ongoing U.S.-Iran contacts, intermittent ceasefire reports and naval activity around key choke points keep markets alert to a reversal in risk sentiment. Even as traders buy the narrative of de-escalation, any setback in negotiations or fresh incidents in the Gulf could quickly restore haven demand for the dollar and U.S. Treasuries.

Analysts note the rally is largely driven by event risk fading and should be viewed in the context of policy developments, especially Fed guidance and regional central bank actions. Market participants expect continued sensitivity to headlines in the near term and recommend watching oil, U.S. policy cues and upcoming Asian data releases for clues on whether currency gains can be sustained. Risk management remains a priority amid a still-fragile recovery in risk appetite.
