The U.S. dollar reached its highest level in over a year last week, driven by investor enthusiasm for the country’s artificial intelligence (AI) sector and expectations of higher interest rates, despite ongoing concerns about the unpredictability of President Donald Trump’s policies. Since the end of January, the dollar has gained more than 5 percent, reversing some of the decline experienced following Trump’s announcement of steep global tariffs in April 2025.

Trump’s tariff plans, the most extensive import taxes proposed since the 1930s, initially unsettled markets, causing declines across U.S. stocks, bonds, and currency. Still, foreign investors, attracted by the robust growth in AI and technology sectors, have increased their holdings in the dollar and U.S. tech stocks. For example, ASML Holding, a semiconductor equipment manufacturer, has seen shares rise nearly 125 percent over the past year. Despite wariness about the president’s erratic approach, investors have prioritized opportunities in the U.S. economy.

The Federal Reserve’s recent policy stance has been central to the dollar’s resurgence. New Fed Chairman Kevin Warsh reassured markets of a firm commitment to reducing inflation, rejecting Trump’s calls for lower interest rates. With inflation remaining above target, the Fed indicated that rate increases are likely, which has attracted additional foreign capital. Of the Federal Open Market Committee’s 18 members, half expect at least one rate hike this year, while only one anticipates a cut.

Economic indicators reinforce this outlook. The Commerce Department reported that U.S. economic growth in the first quarter rose to an annual rate of 2.1 percent, up from an earlier estimate of 1.6 percent. Job creation has also strengthened, with an average of 114,000 new jobs per month through May, a significant improvement over last year’s pace.

The stronger dollar benefits American tourists traveling abroad, making destinations like Europe and Japan more affordable. However, the appreciation also poses challenges for U.S. multinational companies such as Intel, Microsoft, and Qualcomm, as profits earned overseas translate into fewer dollars. Similarly, exports, which have increased for four consecutive months, could face headwinds if the dollar remains elevated.

While the U.S. dollar has consolidated its position, some global central banks are cautiously reducing their dollar reserves in favor of gold, which has gained ground as a safe-haven asset amid geopolitical uncertainties and unpredictable U.S. policies. Gold now comprises 27 percent of global central bank reserves, surpassing holdings in U.S. Treasury securities, according to the European Central Bank. Countries with higher geopolitical risks, including China, Poland, Turkey, and India, have been among the largest purchasers.

Despite the dollar’s recent strength, concerns persist about the long-term fiscal health of the United States. The federal budget deficit for the current fiscal year is projected to exceed $1.8 trillion, or nearly 6 percent of gross domestic product, levels typically associated with wartime or financial crisis conditions. The national debt has reached $31.6 trillion, surpassing the size of the economy, with annual interest payments approaching $1 trillion. Some foreign investors have already reduced their exposure to U.S. Treasury securities, citing worries over fiscal sustainability.

In addition, recent U.S. export controls, financial sanctions, and restrictions on advanced AI technologies have raised apprehensions among global governments about increasing dependency on the United States. Analysts caution that the dollar’s appreciation reflects current economic fundamentals rather than a full restoration of international trust in U.S. leadership.
