The Federal Reserve unanimously raised its benchmark overnight interest rate by a quarter of a percentage point, moving it to a range of 3.75%-4.00%. This marks the first rate hike since 2023 and is intended to combat inflation, which has been elevated for the past five years due to factors like global import tariffs, an energy shock from the U.S.-Israeli war with Iran, and capital spending from the AI boom. New Fed Chairman Kevin Warsh joined the unanimous decision, despite President Donald Trump's stated preference for lower rates, underscoring concerns about persistent price pressures and a resilient labor market.

New projections from Fed officials show the policy rate reaching a 4.00%-4.25% range by the end of 2026, remaining unchanged at the end of 2027. This hawkish signal suggests openness to further tightening, which is expected to support the dollar. Bond traders had largely anticipated this move, with interest-rate swaps indicating about a 94% chance of a quarter-point hike from the previous 3.5%-3.75% range. Markets are also pricing in additional hikes, with 52 basis points by year-end and 89 basis points by June.

The decision to raise rates carries risks, as higher borrowing costs could weaken an economy already showing signs of strain. Americans are struggling to afford homes, cars, and other big-ticket purchases, and the Fed's move could increase the risk of its inflation fight coming at the expense of economic growth. However, the external picture, including Brent crude aiming for $110/barrel due to delayed Iran-Gulf negotiations and softness in tech stocks, suggests that markets are more likely to fade any negative dollar reaction, unless a significant dovish surprise occurs. The dollar's strength is further supported by the current energy price backdrop and relative political stability compared to potential US midterm risks.
