Wall Street slipped to the downside on Tuesday as fears over a stalled U.S.–Iran cease‑fire conversation intensified. After a brief morning rally, the S&P 500 shed 0.5%, while the Nasdaq fell 0.8%. Oil prices surged to $89 a barrel, reflecting heightened geopolitical risk in the Middle East and 28‑year‑old investors who had been watching the diplomatic corridor closely for a potential deal extension.

The market reaction mirrored last week's surge in Treasury yields, which rose 10 basis points after the Federal Reserve’s Kevin Warsh testified. However, the testimony itself failed to sway investors, who instead focused on the looming deadline for the cease‑fire extension set for Wednesday. Volatility spiked to its highest level since the cease‑fire began, sparking a sell‑off in risk assets.

Vice President JD Vance’s decision to postpone a planned trip to Pakistan further dented sentiment, as market watchers linked the move to a potential diplomatic pullback. Oil traders seized the uncertainty, driving prices higher, while equity investors re‑evaluated exposure to Middle East‑linked sectors. The day closed with a broader retreat, signaling that investors will wait for clearer signals before committing to new positions.
