Asian Currencies Gain Slightly as Dollar Weakens Amid U.S. Debt Worries

Asian currencies edged higher on Thursday, supported by a weaker U.S. dollar as investor concerns grew over mounting U.S. debt and fiscal instability. The U.S. Dollar Index slipped 0.1%, marking its fourth consecutive day of losses, as markets turned cautious ahead of a crucial House vote on President Donald Trump’s new tax cut proposal.

The proposed legislation aims to extend the 2017 tax cuts and introduce additional tax breaks. However, critics warn that it could add between $3 trillion and $5 trillion to the national debt over the next decade, potentially deepening the U.S. fiscal deficit. Moody’s recently downgraded the U.S. credit rating from "Aaa" to "Aa1", citing rising debt levels, which added pressure on the greenback.

Investors are also watching the G7 finance ministers’ meeting in Canada, where discussions on global economic stability and potential currency agreements are expected. Analysts at ING noted that U.S. Treasury Secretary Scott Bessent’s upcoming bilateral meetings could provide clues on international currency policy coordination.

Despite broader gains in Asia, the South Korean won weakened, with the USD/KRW pair climbing 0.5%, reversing sharp gains from the previous session amid U.S. pressure on Seoul to support the won. The Japanese yen also dipped, with USD/JPY up 0.4%, even after officials from both countries stated that current exchange rates reflect market fundamentals.

Other regional currencies remained stable. The offshore and onshore Chinese yuan pairs were largely flat, while the Australian dollar held steady. The Singapore dollar and Indian rupee saw modest strength, with USD/SGD and USD/INR both slipping 0.1%.

As debt concerns weigh on the dollar, currency markets remain sensitive to U.S. fiscal developments and global economic policy signals.
