The U.S. dollar remained close to a one-month high on Wednesday, while most Asian currencies moved within narrow ranges ahead of the Federal Reserve’s upcoming interest rate decision.
The Australian dollar was one of the region’s weakest performers after inflation data came in below market expectations. Meanwhile, renewed tensions between the United States and Iran encouraged cautious trading and increased demand for safe-haven assets.
The U.S. Dollar Index stayed near 101.3, close to its highest level in approximately one month.
Australian Dollar Falls After Soft Inflation Data
The AUD/USD pair declined by around 0.4% after Australia reported weaker-than-expected inflation.
The softer consumer price data reduced expectations that the Reserve Bank of Australia would deliver another interest rate increase. As a result, traders lowered their outlook for further monetary policy tightening.
The New Zealand dollar also weakened slightly, with the NZD/USD pair trading modestly lower.
In contrast, the South Korean won strengthened. The USD/KRW pair fell by approximately 0.6%, pushing the won close to its strongest level since May 6.
Euro Recovers While Pound Remains Under Pressure
The euro edged higher against the U.S. dollar after EUR/USD touched a one-month low during the previous trading session.
However, the British pound remained under pressure. The GBP/USD pair continued to trade near its weakest level since early July as investors avoided taking large positions before key central bank decisions.
U.S.-Iran Tensions Support the Dollar
Geopolitical concerns also influenced currency markets.
Oil prices remained elevated after Iran launched new missile attacks targeting U.S. forces in the Middle East. The attacks ended a period of relative calm that had followed recent ceasefire efforts.
The renewed conflict raised concerns that higher oil prices could create additional inflationary pressure. These worries emerged only hours before the Federal Reserve was due to announce its latest policy decision.
Higher energy prices can make it more difficult for central banks to control inflation. Therefore, investors are watching closely for any indication that the Fed may keep monetary policy restrictive for longer.
Markets Await the Federal Reserve Decision
Financial markets are currently pricing in roughly a 33% probability of a 25-basis-point interest rate increase.
Nevertheless, most investors still expect the Federal Reserve to leave rates unchanged.
DBS senior foreign exchange strategist Philip Wee said traders remain divided over whether Fed Chair Kevin Warsh will support the dollar’s recent strength with a hawkish policy message.
Investors have accumulated long-dollar positions because they expect rising oil prices to keep inflation elevated. However, those positions could quickly unwind if the Federal Reserve fails to signal that another rate increase remains possible in September.
A less hawkish message could weaken the dollar, particularly if policymakers appear more concerned about economic growth than inflation.
Bank of Japan and Bank of England Decisions in Focus
Once the Federal Reserve announces its decision, attention will shift toward other major central banks.
The Bank of Japan and the Bank of England are both expected to release monetary policy decisions later this week.
Traders will monitor the announcements for changes in interest rate expectations, inflation forecasts and guidance about future policy moves.
Chinese Yuan Trades in a Tight Range
The Chinese yuan remained stable as investors waited for clearer signals from the Federal Reserve.
Both the onshore USD/CNY pair and the offshore USD/CNH pair traded within narrow ranges. Market participants appeared reluctant to build large positions in Asian currencies before the Fed’s announcement.
Elsewhere in the region, the Philippine peso strengthened slightly, while the Singapore dollar remained broadly unchanged.
Indonesian Rupiah Faces Policy Uncertainty
Indonesia’s rupiah remained in focus following the unexpected resignation of Bank Indonesia Governor Perry Warjiyo earlier this week.
The departure raised concerns about monetary policy continuity and the future direction of Indonesia’s central bank.
However, Citi strategist Rohit Garg maintained a positive outlook for the rupiah. Citi continues to expect the currency to strengthen and is expressing that view through short USD/IDR positions.
According to Garg, the rupiah’s recent weakness was mainly driven by speculation surrounding the governor’s resignation rather than a meaningful deterioration in Indonesia’s economic fundamentals.
The focus has now shifted toward Indonesian policymakers. They will need to reassure investors that monetary policy will remain stable and consistent despite the leadership change.
Clear communication could help restore market confidence and limit further pressure on the rupiah.
Asian Currencies Remain Cautious Before Fed Guidance
Other Asian currencies recorded limited movement.
The Indian rupee was little changed following its recent gains. The Thai baht and Malaysian ringgit also traded within tight ranges as investors waited for fresh guidance from the Federal Reserve.
Overall, currency markets remain cautious. The Fed’s policy statement, its inflation outlook and any signals about a possible September rate increase could determine the next major move for the U.S. dollar and Asian currencies.
