Asian currency markets opened the week on a cautious note as the US dollar softened, while most regional currencies showed little movement. The subdued trading came after reports that the US government has launched a criminal investigation involving Federal Reserve Chair Jerome Powell, raising concerns about the independence of the US central bank—a cornerstone of global financial stability.
At the same time, recent US economic data released late last week pointed to a sharper-than-expected slowdown in job growth, reinforcing expectations that the Federal Reserve may shift toward a more accommodative monetary policy stance. The combination of political uncertainty and weaker macroeconomic signals has prompted global foreign exchange markets to adopt a more defensive posture.

In early-week trading, the US Dollar Index (DXY)—which measures the greenback’s strength against a basket of major currencies—fell by around 0.2%, retreating from its highest level in a month. Futures tied to the index also traded lower by a similar margin, underscoring investor caution.
The decline followed remarks by Jerome Powell, who revealed that the administration had threatened the Federal Reserve with potential criminal prosecution. The issue stems from Powell’s testimony before the Senate regarding cost overruns in the renovation of the Fed’s headquarters. While no official conclusions have been reached, the disclosure was enough to unsettle markets.
Analysts warn that any indication of political interference in the Federal Reserve could significantly undermine global investor confidence. For decades, the Fed’s independence has been viewed as fundamental to ensuring credible and stable US monetary policy.
Across Asia, reactions in currency markets remained muted. Most regional currencies traded sideways or posted only marginal movements, reflecting a wait-and-see approach as investors reassess risk.
The Japanese yen (USD/JPY) edged up about 0.2%, signaling modest demand for safe-haven assets, though not at levels suggesting heightened risk aversion.
The Singapore dollar (USD/SGD) was largely unchanged, supported by Singapore’s stable economic outlook and cautious monetary policy framework.
The South Korean won (USD/KRW) stood out as a notable exception, weakening by approximately 0.7%, pressured by domestic factors and reduced risk appetite among international investors.
In China, the onshore yuan (USD/CNY) remained virtually flat, while the offshore yuan (USD/CNH) strengthened slightly, gaining around 0.1%.
The Indian rupee (USD/INR) also saw little change.
Meanwhile, the Australian dollar (AUD/USD) rose modestly by 0.2%, partly supported by expectations of future Fed rate cuts.
Overall, Asian currency markets appear to be in a holding pattern, prioritizing capital preservation amid growing uncertainty emanating from the United States.
Market unease has been driven less by the investigation itself than by the potential erosion of the Fed’s independence. For decades, the Federal Reserve has been regarded as one of the world’s most credible and autonomous central banks, playing a pivotal role in shaping global monetary conditions.
Should confidence in that independence weaken, the consequences could be far-reaching:
Increased volatility across financial markets, particularly in foreign exchange and bond markets.
Sustained pressure on the US dollar, as its status as a global safe-haven currency comes under scrutiny.
More cautious global capital flows, especially toward emerging markets and Asia.
Some analysts note that while the likelihood of actual prosecution remains remote, the politicization of monetary policy is itself sufficient to prompt investors to reassess short-term strategies.
Beyond political developments, US economic data released on Friday also weighed on the dollar. The report showed that nonfarm payroll growth slowed more sharply than expected in December, pointing to a cooling labor market.
The data is significant, as the Fed has repeatedly emphasized that its interest rate decisions depend heavily on labor market conditions and inflation trends. Softer hiring figures increase the probability that the central bank may pivot toward a more dovish stance to support economic growth.
Markets are currently pricing in at least one additional Fed rate cut in 2026, with some traders anticipating two cuts should economic data continue to weaken.
In the near term, investor attention will focus on the US Consumer Price Index (CPI) for December, scheduled for release on Tuesday. The data is widely viewed as one of the most critical indicators ahead of the Fed’s next policy meeting later this month.
If inflation continues to ease, expectations for rate cuts are likely to strengthen, potentially placing further pressure on the US dollar while offering support to Asian currencies. Conversely, a stronger-than-expected CPI reading could trigger short-term market corrections.
Analysts broadly agree that caution will continue to dominate Asian currency markets in the current environment. Uncertainty surrounding the Federal Reserve, combined with mixed US economic data and persistent geopolitical risks, has left investors reluctant to take aggressive positions.
Over the medium term, the trajectory of Asian currencies will largely depend on:
The extent to which the Fed can maintain its institutional independence
The future path of US monetary policy
Global growth and inflation dynamics
The weakening of the US dollar alongside largely unchanged Asian currencies reflects a sensitive phase for global financial markets. Questions surrounding the independence of the Federal Reserve, coupled with softer US economic signals, have prompted investors to prioritize defensive positioning over risk-taking.
Looking ahead, US inflation data and guidance from the Fed will be critical in shaping the outlook for the dollar and Asian currency markets. Until policy clarity improves, caution is likely to remain the prevailing strategy among global investors.
