The US Dollar Index (DXY) has experienced a notable boost, surpassing the 99.00 mark for the first time in four weeks, marking its fourth consecutive day of gains this Friday. The greenback's resilience is bolstered by a cautious market sentiment, which has heightened due to ongoing political and economic uncertainties, notably US President Donald Trump's tariffs and upcoming employment data for December.
For the week, the dollar is on track to rally approximately 0.60%, and over the past two weeks, it has appreciated by more than 1%. This performance makes the US dollar one of the top-performing major currencies so far in 2026. Much of this strength is attributed to a mild risk-off environment, where investors tend to prefer safe-haven assets amid escalating geopolitical tensions across various regions worldwide. Such tensions tend to support the US dollar, as it is often seen as a global reserve currency during uncertain times.
Trump’s Tariffs and the Supreme Court’s Decision
A significant point of focus Friday is the US Supreme Court’s deliberation on whether President Trump can invoke the International Emergency Economic Powers Act of 1977 to impose trade sanctions on numerous trading partners. This decision could have profound implications for international trade and the dollar’s strength.
According to reports from Reuters, US corporate legal teams have already prepared claims seeking around $150 billion in reimbursement for import levies paid by companies, should the court rule against the administration. These claims highlight the financial impact tariffs can have on businesses.
Adding to the political tension, the Labor Department is set to release December’s Nonfarm Payrolls report at 13:30 GMT. Market analysts expect a moderate increase of around 60,000 jobs for December, slightly down from November’s 64,000. The unemployment rate is forecasted to decline marginally from 4.6% to 4.5%.
Unless the data deviate significantly from these forecasts, they are unlikely to influence the ongoing divergence among Federal Reserve policymakers regarding the pace of future monetary easing. Current futures markets suggest there is about a 13% chance of a rate cut following the Fed’s January 27-28 meeting, with market expectations for a potential cut in March decreasing from 44% to approximately 36.5% over the past week.
