Stock futures fell on Sunday night as renewed tensions over stalled U.S.–Iran peace talks and unrest in the Strait of Hormuz pushed oil prices higher.

Major indexes including the Dow, S&P 500, and Nasdaq futures all dipped slightly ahead of a busy week for markets.

President Donald Trump cancelled planned envoy talks, saying negotiations could proceed by phone, while Iran said no meeting is scheduled.

At the same time, Iranian forces reportedly seized vessels near the key shipping route, adding to global supply concerns and driving oil prices above $107 for Brent crude, CNBC has reported.

Despite the geopolitical pressure, analysts said markets still expect longer-term de-escalation as attention now turns to major corporate earnings and a Federal Reserve policy decision.
