US Markets Slide as Fed Signals Potential Rate Hikes Amid Inflation Fears

Wall Street faced a sharp sell-off on Wednesday as the Federal Reserve’s latest policy stance shifted toward a more hawkish tone. Major indices, including the S&P 500 and Nasdaq, tumbled by over 1% as investors adjusted their expectations for interest rate trajectories later this year.

Fed Holds Rates Steady but Signals Hawkish Shift

While the Federal Reserve maintained interest rates within the 3.50%-3.75% range as anticipated, the underlying sentiment has turned decidedly aggressive. The central bank's policy statement notably removed previous language that hinted at the possibility of rate cuts within this year. Instead, new quarterly projections revealed that nine central bank officials now expect at least one rate hike before the end of 2026.

A significant departure from tradition occurred as new Fed Chair Kevin Warsh chose not to submit an interest-rate-path projection as part of the quarterly forecasts. In his communications, Warsh emphasized a rigorous commitment to price stability, highlighting the urgent need to tame inflation pressures exacerbated by oil-price spikes linked to the Iran war.

Market Reaction and Trading Probability Shifts

The shift in sentiment was immediately reflected in the equity markets. The S&P 500 dropped 89.59 points, or 1.19%, to close at 7,421.76. The Nasdaq Composite saw a steeper decline, falling 349.14 points (1.32%) to end at 26,027.21, while the Dow Jones Industrial Average slid 499.18 points, or 0.96%, to finish at 51,494.99.

Investor sentiment regarding interest rates has undergone a massive realignment. According to the CME Group's FedWatch tool, the probability of rates holding steady by year-end crashed from 40% on Tuesday to just 15.7% following the Fed's announcement. Currently, traders are pricing in a nearly 38% chance of a 25-basis-point hike by December, with a 33% probability of a more aggressive 50-basis-point hike.

Volatility Driven by Geopolitics and Economic Data

La volatilité des marchés a été accentuée par l'incertitude géopolitique et des signaux économiques mitigés. Bien que les ventes au détail aux États-Unis aient affiché une vigueur inattendue en mai — portées par les achats de véhicules malgré la hausse des prix de l'essence — les prix du pétrole ont remonté mercredi. Cela fait suite aux commentaires du président Donald Trump suggérant que l'accord de paix préliminaire entre les États-Unis et l'Iran n'était pas définitif, faisant planer le spectre d'un nouveau conflit.

Sur le front des entreprises, les actions de CME Group ont subi des pressions après l'annonce du départ du PDG Terry Duffy le 1er mars pour assurer la transition vers le rôle de président exécutif. À l'inverse, l'action Allbirds a bondi après que l'entreprise a changé de nom pour devenir « Smartbird », suite à son pivot vers l'IA et à la nomination de l'ancienne cadre d'Amazon Nadia Carlsten au poste de PDG.
