Lead Story#
U.S. stock futures fell and oil prices jumped nearly 3% on Sunday evening after Iran claimed it had once again shut down the Strait of Hormuz amid stalled peace talks. The geopolitical escalation, coupled with President Donald Trump’s threats of fresh strikes on Iranian proxies, is casting a shadow over early-week trading.
Markets & Economics#
Energy markets are bracing for turbulence as West Texas Intermediate crude surged to roughly $78.70 a barrel and Brent topped $81 following Iran’s claim of a Strait of Hormuz blockade. These rising energy costs arrive at a critical moment for the Federal Reserve, with the crucial May PCE inflation gauge—the central bank’s preferred metric—due Thursday. Under its new chairman, Kevin Warsh, the Fed is launching five task forces to fundamentally overhaul its communications, data usage, and balance sheet strategies, marking a “quiet revolution” in modern monetary policy. Meanwhile, Wall Street equity futures slipped, with the S&P 500 and Nasdaq-100 indicating a lower open after a strong, tech-led finish to last week.
