US Markets Slump as Fed Signals Potential Rate Hikes to Combat Inflation

Wall Street witnessed a sharp sell-off on Wednesday as major indices tumbled following the Federal Reserve's decision to maintain current interest rates. While the pause was anticipated, the central bank's hawkish tone and revised economic projections have led traders to recalibrate their expectations toward future rate hikes.

Fed Maintains Rates but Shifts to a Hawkish Stance

The Federal Reserve opted to keep interest rates unchanged within the 3.50%-3.75% range, a move widely expected by market participants. However, the underlying sentiment from the central bank was decidedly more aggressive than many had hoped. In a departure from previous policy language, the Fed’s official statement removed references to the likelihood of interest rate cuts within this year.

New quarterly projections revealed that nine central bank officials now anticipate at least one rate hike by the end of 2026. Adding to the market's uncertainty, incoming Fed Chair Kevin Warsh broke with traditional practice by not submitting a formal interest-rate-path projection. Warsh emphasized that the central bank's primary mission remains price stability, specifically aiming to tame inflation pressures exacerbated by recent oil-price spikes linked to the Iran war.

Market Reaction: Nasdaq and S&P 500 Take the Hit

The shift in sentiment immediately impacted equity markets, erasing recent gains. The S&P 500 dropped 89.59 points, or 1.19%, to close at 7,421.76. The tech-heavy Nasdaq Composite saw a steeper decline, losing 349.14 points (1.32%) to end at 26,027.21. Even the Dow Jones Industrial Average was not immune, falling 499.18 points, or 0.96%, to close at 51,494.99.

The volatility was further fueled by shifting geopolitical dynamics. While stocks had previously rallied on news of a preliminary U.S.-Iran peace deal, President Donald Trump’s subsequent comment that the agreement was not final caused oil prices to edge back up, adding more inflationary concern to the investor psyche.

Traders Pivot Toward Higher Interest Rate Bets

The Fed's commentary has caused a massive shift in market pricing. According to CME Group's FedWatch tool, the probability of rates holding steady through the end of the year plummeted from 40% on Tuesday to just 15.7% following the meeting.

投資家は現在、今年第4四半期における大幅な動きを織り込み始めています。市場の予測では、12月までに25ベーシスポイントの利上げが行われる確率が約38%である一方、より積極的な50ベーシスポイントの利上げが行われる確率は約33%となっています。この変化は、根強いインフレに対する市場の懸念の高まりと、物価を安定させるためのFRBの「タカ派的な姿勢（hawkish tilt）」へのコミットメントを浮き彫りにしています。
