Asian currencies delivered mixed performances on Tuesday as investors reacted to major central bank decisions, shifting monetary policy expectations, and uncertainty surrounding the US midterm elections.
The Australian dollar weakened despite an interest rate increase by the Reserve Bank of Australia (RBA), while the Chinese yuan declined following a new policy announcement from the People’s Bank of China (PBOC).
Meanwhile, the South Korean won strengthened, supported by robust export figures and improving confidence in the country’s economic outlook.
Asian Currencies Mixed as US Dollar Edges Lower
The US Dollar Index (DXY), which measures the greenback against six major currencies, declined 0.12% to approximately 101.69.
The Australian dollar slipped 0.2% to $0.6988, reflecting a cautious market response to the RBA’s latest interest rate decision.
In contrast, the South Korean won gained 0.5%, strengthening to approximately 1,339.37 against the US dollar.
The Chinese yuan also faced selling pressure. The offshore yuan weakened 0.37% to 6.6710 per dollar, while its onshore counterpart declined 0.38% to 6.6731.
Elsewhere, the Taiwan dollar fell 0.6%, making it one of the weakest regional currencies during the session.
The Philippine peso and Indonesian rupiah declined 0.34% and 0.4%, respectively. The Singapore dollar and Malaysian ringgit also recorded losses.
Meanwhile, the Indian rupee remained relatively stable near 94.918 per dollar.
The Japanese yen edged higher to approximately 157.80 against the dollar amid reduced trading activity during a Japanese market holiday.
Outside Asia, the New Zealand dollar gained 0.1% to $0.5629, while the euro and British pound advanced 0.13% and 0.1%, respectively.
Australian Dollar Falls Despite RBA Interest Rate Hike
The Reserve Bank of Australia increased its benchmark cash rate by 25 basis points to 4.85%, marking its fifth interest rate hike of 2026.
The decision pushed Australian borrowing costs to their highest level in 18 years.
Although financial markets widely anticipated the increase, the central bank’s divided vote attracted considerable attention.
Six members of the nine-person Monetary Policy Board supported raising rates, while three preferred to maintain the previous level.
The Australian dollar briefly declined as much as 0.4% following the announcement.
Investors interpreted the split decision as a possible indication that the RBA is approaching the end of its monetary tightening cycle.
RBA Inflation Outlook Raises Questions About Future Rate Decisions
Despite raising interest rates, the Reserve Bank of Australia acknowledged that existing monetary conditions are already restrictive.
Capital Economics economist Marcel Thieliant suggested that the central bank appeared increasingly confident that borrowing costs were sufficiently high to contain inflation.
The research firm expects the RBA’s next interest rate adjustment to be a reduction, potentially beginning in late 2027.
However, inflation remains a significant concern for Australian policymakers.
The RBA increased its forecast for trimmed mean inflation to 3.5% by mid-2027, compared with its previous projection of 3.0%.
Higher energy and commodity prices, partly associated with the conflict in the Middle East, have contributed to persistent inflationary pressures.
Domestic capacity constraints have also complicated efforts to restore price stability.
Consequently, the timing of any future interest rate cuts will depend heavily on upcoming economic indicators and inflation developments.
Chinese Yuan Weakens Following PBOC Policy Adjustment
The Chinese yuan retreated after the People’s Bank of China announced changes to foreign exchange reserve requirements for financial institutions.
The central bank plans to increase the foreign exchange reserve requirement ratio from 4% to 6%, effective November 15.
The adjustment is expected to absorb approximately $24 billion in dollar liquidity from China’s financial system.
By reducing available foreign currency liquidity, policymakers aim to moderate the yuan’s recent appreciation and discourage excessive one-directional currency speculation.
The Chinese currency has strengthened more than 5% against the US dollar since the beginning of 2026.
Strong exports, substantial trade surpluses, and increased foreign currency conversions by Chinese businesses have supported that advance.
However, authorities appear concerned that an excessively rapid appreciation could create challenges for the country’s export-oriented economy.
The latest policy decision highlights Beijing’s efforts to maintain currency stability while balancing trade competitiveness and financial market conditions.
South Korean Won Gains as Exports Surge to Record Levels
Unlike several regional currencies, the South Korean won advanced against the US dollar.
Strong export performance has helped support confidence in South Korea’s economic outlook.
Official data showed that the country’s exports surged 93.7% year-over-year in October, reaching a record $115.28 billion.
The increase represented the fastest annual export growth since January 1974.
Semiconductor shipments were particularly strong, jumping 259.4% compared with the previous year.
Robust global demand for advanced chips, particularly those used in artificial intelligence infrastructure, contributed significantly to the export expansion.
The won also benefited from its recent upward momentum, having strengthened approximately 13% against the dollar during the third quarter.
That performance marked its strongest quarterly appreciation since late 1998.
Meanwhile, South Korea’s annual inflation eased to 2.8% in October from 2.9% in September.
Although inflation moderated, it remained above the Bank of Korea’s 2% target, leaving monetary policymakers with important decisions ahead.
US Midterm Elections and Federal Reserve Outlook in Focus
Beyond Asian central bank decisions, investors are closely monitoring political and economic developments in the United States.
The November 3 US midterm elections could influence fiscal policy, regulatory priorities, and broader financial market sentiment.
Market participants are also awaiting Friday’s US employment report, which could affect expectations for the Federal Reserve’s next monetary policy decision.
DBS economists forecast that US nonfarm payrolls increased by approximately 100,000 in October, compared with a previously reported gain of 29,000.
A stronger-than-expected employment reading could reinforce expectations that the Federal Reserve will maintain a restrictive policy stance.
Conversely, weaker labor market figures could reduce the likelihood of further interest rate increases.
These developments could significantly influence the US dollar and Asian currency markets in the coming sessions.
Asian Forex Markets Await More Central Bank Decisions
Several additional economic events could influence Asian currencies later this week.
Bank Negara Malaysia is scheduled to announce its latest monetary policy decision on Thursday.
DBS expects the Malaysian central bank to maintain its benchmark interest rate at 2.75%.
Investors will also monitor October inflation reports from Taiwan, Thailand, and the Philippines for further evidence of regional price pressures.
For now, Asian currencies remain sensitive to changes in global interest rate expectations, economic growth forecasts, and geopolitical developments.
The Australian dollar’s weakness following the RBA rate hike and the Chinese yuan’s decline after the PBOC announcement demonstrate how central bank communication can influence currency markets beyond the immediate policy decision.
With US election developments and employment figures approaching, volatility across Asian forex markets could increase as traders reassess the outlook for monetary policy and international capital flows.
