• S&P 500: +0.25% | NASDAQ 100: +0.51% | Dow Jones: +0.10%
• Iran attacks added pressure on oil prices, capping broader market gains
• Haven dollar made a comeback as a hedge to equities per Bloomberg
• Gold and silver surged on geopolitical safe-haven flows
• Fed two-day meeting opened, with a rate decision and Micron (MU) earnings looming on Wednesday

U.S. equity markets posted modest gains on March 17, 2026, with the S&P 500 rising 0.25%, the NASDAQ 100 advancing 0.51%, and the Dow Jones Industrial Average edging up 0.10%. The session was marked by cross-currents: optimism around the opening of the Federal Reserve's policy meeting was tempered by escalating Iran tensions that sent oil prices higher and pressured energy-sensitive sectors of the economy. The Dow briefly fell as much as 471 points intraday before recovering, illustrating the tug-of-war between risk appetite and geopolitical anxiety.

The dollar staged a comeback as a haven asset, with Bloomberg reporting the greenback reasserting itself as a hedge against equity volatility. Gold and silver surged on safe-haven demand, while Bitcoin surprised observers by remaining relatively calm near $74K–$75K, prompting debate about whether crypto is genuinely decoupling from traditional risk assets.

Bitcoin held near $74K–$75K, described by Bloomberg as an 'oasis of calm' while Iran-related war fears jolted traditional markets. The resilience fueled renewed debate about crypto's decoupling from equities, though Citigroup cut its 12-month bitcoin and ether price targets as U.S. crypto legislation stalled. Ethereum staking reached 30% of total supply, tightening the available market float and potentially supporting prices. XRP reclaimed its position as the 4th-largest cryptocurrency by market cap.

On the regulatory front, the SEC issued its first-ever formal definitions for which crypto assets qualify as securities, a landmark development. However, a senator proposed banning crypto holdings in Social Security accounts, and TD Cowen warned that the crypto bill window may extend to August recess with potential delays to 2027. Chicago crypto broker BlockFills filed for bankruptcy following a selloff, highlighting ongoing stress in crypto intermediaries.
