US stocks and Treasuries experienced a rally as oil prices retreated, fueling optimism that inflation could be controlled following the Federal Reserve's decision to raise interest rates for the first time in over three years. Futures for the S&P 500 rose 0.7%, while Nasdaq 100 futures climbed 0.8%. Brent crude, trading below $105 a barrel, headed for its first back-to-back losses this month, falling 1%. The yield on the 10-year US Treasury note decreased by four basis points to 4.99%, while gold gained 1.3% to $4,320.74 an ounce.

The unanimous decision by the Fed, led by Chairman Kevin Warsh, to raise rates was viewed by traders as a positive step, bolstering his credibility in the fight against inflation. This move calmed market pressures, which had built up around price increases. Despite the immediate relief, some investors remain cautious about the extent of future rate hikes.

The Fed's dot plot suggests one more rate hike this year, though money markets are pricing in a total of three hikes over the next 12 months. Joachim Klement, a strategist at Panmure Liberum, believes that market expectations for additional rate hikes in 2027 are likely overdone, predicting that bond yields will move lower, which in turn should support stock markets.

While the market response was largely positive, with global bonds recovering and yields on 10-year Treasuries falling three basis points, the hawkish stance of the Fed has left some investors feeling edgy. The uncertainty regarding how aggressively the Fed will continue to raise rates to manage prices is expected to cause volatility in both stock and bond markets in the coming weeks. The hike was the first since 2023, and analysts note the unanimous vote could signal a more hawkish path ahead.
