Asian Currencies Steady as Dollar Hits 3-Month Low on US Treasury Action

Most Asian currencies steadied on Thursday, holding onto recent gains as the U.S. dollar remained near a three-month low. The dollar's weakness was triggered by a U.S. Treasury Department announcement aimed at calming a volatile bond market, which in turn caused a significant retreat in long-term borrowing costs.

Treasury Move Halts Bond Selloff

The U.S. Treasury stated it would double the size of some buyback operations for longer-dated bonds, increasing them to $4 billion from a previous $2 billion per operation. The move, which targets securities with maturities of 10 years or more, successfully eased intense selling pressure in the bond market.

In response, the U.S. 30-year Treasury yield pulled back from a 19-year high of 5.337% to around 5.18%. The decline in U.S. yields reduced the relative attractiveness of holding dollar-denominated assets, causing the dollar index to fall 0.8% on Wednesday and trade near 98.80, its lowest point since late May.

Regional Currency Roundup

The shift in U.S. yields provided breathing room for several regional currencies that had been under pressure. Key movements included:

• The Japanese yen (USD/JPY) saw the dollar edge up 0.2% to 158.43, following a nearly 1% slide in the previous session. The yen remains supported by market expectations of further monetary tightening by the Bank of Japan.
• The South Korean won (USD/KRW) gained 0.4%, recovering from a 1.8% tumble overnight that had pushed it near a one-year low.
• The Indian rupee (USD/INR) strengthened against the dollar after five straight sessions of losses, finding relief from the twin pressures of high U.S. yields and rising oil prices.
• The Australian dollar (AUD/USD) held steady after a 0.5% gain, while the onshore Chinese yuan (USD/CNY) edged slightly higher.

Fed Minutes and Oil Prices in Focus

Despite the dollar's immediate weakness, investors are weighing other factors that could influence currency markets. Minutes from the Federal Reserve's July meeting showed that officials remained concerned about persistent inflation, with some policymakers indicating a willingness to raise interest rates further if necessary.

Additionally, rising energy costs serve as a source of caution. Global crude oil prices climbed back toward $92 a barrel, posing a headwind for oil-importing economies in the region and potentially complicating the inflation outlook for central banks.
