NEW YORK, New York - Wall Street suffered a sharp sell-off on Wednesday after the Federal Reserve announced it would hold interest rates steady, citing heightened uncertainty following the continuing military strikes by the U.S. and Israel against targets in Iran.

The central bank's decision to pause its easing cycle, combined with escalating geopolitical tensions in the Middle East, rattled investor confidence and triggered a broad-based retreat across North American exchanges.

The Dow Jones Industrial Average bore the brunt of the selling pressure, tumbling 768.45 points to close at 46,224.81. The loss of 1.64 percent marked one of the worst sessions for the blue-chip index in recent months.

The broader Standard and Poor's 500 also saw significant declines, falling 91.35 points to finish at 6,624.74. The benchmark index, which had been hovering near record highs, recorded a drop of 1.36 percent as traders fled to safety.

Technology stocks fared little better, dragging the NASDAQ Composite down by 327.11 points. The tech-heavy index settled at 22,152.42, a decrease of 1.46 percent, as concerns over future rate policy weighed heavily on growth-oriented sectors.

Fed Chair Jerome Powell noted in a post-meeting press conference that while inflation showed signs of moderating, the "geopolitical landscape, particularly the recent actions in Iran, introduces a significant risk to the economic outlook that requires a cautious approach."

Analysts suggest that until the ramifications of the Middle East conflict become clearer, volatility is likely to persist across global equity markets.

U.S. Dollar Displays Strength Across the Board in Wednesday Trading

The U.S. dollar put in a solid performance against major peers on Wednesday, gaining ground against all the majors.

The most notable move of the session was the dollar's sharp advance against the Swiss franc. The USD/CHF pair surged to 0.7925, representing a gain of 1.09 percent for the greenback. This suggests a shift in investor sentiment away from the traditional safe-haven currency.

The dollar also strengthened modestly against the Japanese yen, with USD/JPY climbing 0.51 percent to trade at 159.78. Meanwhile, the US dollar / Canadian dollar rate edged up 0.23 percent to 1.3721, indicating slight weakness in the loonie.

The euro and pound, both slid against the dollar. The EUR/USD pair dipped to 1.1472, a loss of 0.58 percent for the common currency, while the GBP/USD pair retreated 0.55 percent to 1.3280. These moves point to ongoing pressure on UK and European currencies despite the broader dollar strength seen elsewhere.

Commodity-linked currencies from the Pacific region were the session's biggest laggards. The Australian dollar / US dollar pair fell sharply by 0.90 percent to 0.7040. The New Zealand dollar / US dollar followed a similar trajectory, dropping 0.83 percent to trade at 0.58087, as risk sentiment appeared to cool in the Asia-Pacific session.

In Canada, the S&P/TSX Composite Index posted the steepest decline among major North American indices, plunging 616.42 points to close at 32,312.67. The drop of 1.87 percent reflected broad-based weakness in both energy and financial stocks amid the uncertain outlook.
