The US dollar stumbled at the start of the week, and the reason goes well beyond routine market jitters. A rare and politically sensitive move by the US Department of Justice (DOJ)—issuing subpoenas to Federal Reserve Chair Jerome Powell—has unsettled investors and reignited concerns about the independence of the US central bank.
Let’s break down what happened, why markets reacted so sharply, and what it could mean for the dollar going forward.
Why Did the Dollar Fall?
Quick answer for featured snippets:
The dollar fell because investors fear political pressure on the Federal Reserve after the DOJ subpoenaed Fed Chair Jerome Powell, raising doubts about central bank independence and future interest rate decisions.
On Monday, the US dollar index fell about 0.37%, slipping to 98.87, as traders reassessed the risks facing US monetary policy. The trigger was Powell’s confirmation that the Fed received DOJ subpoenas related to his congressional testimony on cost overruns tied to a $2.5 billion renovation project at the Fed’s Washington headquarters.
Powell described the legal action as a “pretext” to influence interest rate policy, a statement that immediately alarmed currency markets.
Why Fed Independence Matters to Investors
The Federal Reserve’s credibility rests heavily on its independence from political pressure. When that independence appears threatened, investors tend to react swiftly—and cautiously.
According to Marc Chandler of Bannockburn Global Forex, the subpoenas effectively ended the dollar’s early-year rally, overwhelming even geopolitical developments that usually support the greenback.
Although the White House has denied that President Donald Trump directed the investigation, markets remain uneasy—especially since Trump has repeatedly called for deep interest rate cuts.
Powell’s Exit and the Political Clock
Adding to the uncertainty is the fact that Jerome Powell’s term as Fed Chair ends in May. While he could remain on the Fed’s Board of Governors, Trump is widely expected to nominate a more dovish successor.
Reports suggest that Rick Rieder of BlackRock, among others, is being considered. Meanwhile, US Senator Lisa Murkowski has backed efforts to block new Fed nominees until the DOJ matter is resolved, further muddying the outlook.
For currency traders, this political backdrop makes it harder to price the future path of US interest rates—usually a key support for the dollar.
Other Forces Moving the Dollar
Despite Monday’s drop, the dollar is not without support:
- A strong US jobs report reinforced expectations that the Fed will hold rates steady at its January policy meeting.
- Fed funds futures now suggest the next rate cut may not arrive until June.
- Ongoing geopolitical tensions, including developments involving Iran, Venezuela, and US trade policy, continue to fuel safe-haven demand.
However, analysts at Nomura point out that near-term pressure remains, citing Fed independence risks and the possibility of a US Supreme Court ruling against Trump-era tariffs under the International Emergency Economic Powers Act (IEEPA).
Currency Highlights: Euro, Swiss Franc, and Yen
- Euro: Rose 0.29% to $1.1671, benefiting from the dollar’s weakness.
- Swiss franc: One of the top performers, with the dollar down 0.54% against it—classic risk-off behavior.
- Japanese yen: Bucked the trend, weakening to a one-year low, as soft wage data and expectations of delayed Bank of Japan rate hikes weighed heavily.
What Should Investors Watch Next?
Featured snippet takeaway:
Markets are watching US inflation data, Fed leadership changes, and Supreme Court rulings on tariffs to assess the dollar’s next move.
Key events to monitor include:
- US consumer inflation data for December
- Developments around Powell’s replacement
- The Supreme Court’s decision on US tariff legality
- Any further signs of political pressure on the Fed
Bottom Line
The dollar’s decline isn’t just about numbers—it’s about trust. When questions arise over the independence of the Federal Reserve, markets react fast and decisively. While strong economic data still provides a cushion, political uncertainty has introduced new risks that could keep the dollar under pressure in the near term.
For now, investors are bracing for volatility—and listening closely to every signal coming out of Washington.
