Asian foreign exchange markets were largely subdued on Tuesday as investors stayed on the sidelines amid renewed U.S.-Iran hostilities in the Strait of Hormuz and ahead of the Reserve Bank of Australia's policy announcement. Thin liquidity from regional holidays compounded muted activity. The RBA delivered a 25 basis-point hike to take the cash rate to 4.35%, while the U.S. dollar saw modest safe-haven demand and oil prices remained elevated after a sharp prior session gain.

Key Points

  • RBA raised its cash rate by 25 basis points to 4.35%, its third consecutive hike, citing persistent inflation and Middle East risks - impacting interest-rate sensitive assets and the Australian dollar.
  • Safe-haven demand and higher Treasury yields supported the U.S. dollar, with the U.S. Dollar Index up roughly 0.1% - affecting FX markets and cross-border capital flows.
  • Escalation in the Strait of Hormuz and elevated oil prices above $100 per barrel kept inflationary concerns front of mind, influencing energy and inflation-sensitive sectors.

Asian currencies showed little movement on Tuesday as market participants largely refrained from taking fresh positions amid renewed U.S.-Iran attacks and the Reserve Bank of Australia (RBA) decision later in the day. Liquidity conditions were also thin because of holidays across Japan, China and South Korea, which kept trading volumes subdued.

Market snapshot

The U.S. Dollar Index edged up about 0.1%, extending recent gains supported by safe-haven flows and higher Treasury yields. Oil, which had jumped nearly 6% in the previous session on fears of supply disruption, pulled back slightly as traders took profits but remained elevated above $100 per barrel, keeping inflation concerns prominent for markets.


RBA decision

The Reserve Bank of Australia raised its cash rate by 25 basis points to 4.35%, marking its third straight increase. The central bank cited persistent inflationary pressures as well as risks arising from the Middle East conflict. It said higher fuel and commodity costs were already feeding into inflation and warned of potential second-round effects if firms pass on their rising input costs. The RBA also indicated that inflation is now expected to peak at a higher level than previously projected and to remain above target for longer, with upside risks.

The Australian dollar's AUD/USD pair traded largely flat following the policy announcement.


Geopolitics and regional moves

Tensions intensified in the Strait of Hormuz, a key shipping lane for global oil flows, heightening concerns about potential supply disruptions and their inflationary consequences. U.S. President Donald Trump announced a plan called "Project Freedom" aimed at escorting stranded vessels and reopening shipping lanes through the strait, though market participants took a cautious stance on the plan's likely effectiveness.

Currency moves across Asia were generally muted: USD/JPY traded flat, USD/KRW edged up about 0.3%, the onshore Chinese yuan was largely unchanged, USD/SGD moved little, and USD/INR ticked up around 0.1%.


Implications and outlook

Analysts surveyed by market participants expect Asian currencies to remain range-bound in the near term as the combination of geopolitical risk, oil price volatility and central bank signals keeps traders reluctant to take large directional bets. With thin liquidity from regional holidays, even modest headline moves can fail to translate into sustained currency trends.

Bond markets and energy markets are central to evolving sentiment: higher Treasury yields and elevated oil prices are supporting the dollar and adding to inflation concerns, while central bank actions such as the RBA's hike reinforce the prospect of tighter policy in response to persistent price pressures.

Risks

  • Geopolitical risk in the Strait of Hormuz could lead to supply disruptions in oil, raising inflation and pressuring energy-dependent sectors and inflation-sensitive assets.
  • Thin liquidity during regional holidays in Japan, China and South Korea may amplify price distortions or produce muted market signals, complicating execution for currency and fixed-income traders.
  • Volatility in oil and ongoing central bank tightening may keep Asian currencies range-bound and deter large directional positions, affecting FX, bond and commodity market activity.
