U.S. stock futures were broadly flat early Tuesday after Wall Street declined in the previous session, with higher Treasury yields and oil prices weighing on risk-sensitive assets. Brent crude rose 1.1% to $91.51 a barrel and WTI gained 1.4% to $86.99 by 01:02 ET, extending gains after both contracts jumped nearly 3% on Monday. The rise followed President Donald Trump’s threat of further military action against Iran after U.S. strikes on Iranian military targets on Larak Island and Iran’s missile attacks on U.S. military facilities in Jordan. Concerns about shipping through the Strait of Hormuz intensified after a tanker was struck by three unidentified projectiles while leaving the waterway, according to the United Kingdom Maritime Trade Operations agency. Japan’s benchmark 10-year government bond yield rose above 3% for the first time since September 1996, reflecting concerns about inflation, government spending and further Bank of Japan rate increases. The yield has more than tripled since 2024 as the BOJ moved away from its ultra-loose monetary policy. Markets are also focused on Tuesday’s JOLTS job openings report, ISM manufacturing index and a speech by Fed Governor Michael Barr, followed by Friday’s nonfarm payrolls report. The data will be assessed alongside Fed Chair Kevin Warsh’s recently hawkish tone, which has led markets to price greater odds of a September rate hike.
