Oil is stuck near $100 a barrel, and the weekend made the picture murkier. Brent crude traded around $101.31 on Monday, down 0.92% on the day, even after Yemen's Iran-backed Houthis claimed new missile and drone strikes on Saudi Aramco sites. With US futures slightly lower ahead of the open, investors are asking whether the Red Sea has become the next oil choke point, and what that means for inflation, bond yields and stocks.

What Happened Over the Weekend
On Saturday, the Houthis claimed missile and drone strikes on Saudi Aramco sites in Riyadh and Khurais, while the Saudi-led coalition called the claims misleading. On Sunday, Iran's parliament speaker, Mohammad Bagher Ghalibaf, said the Strait of Hormuz will stay closed until Washington meets seven conditions, according to Modern Diplomacy. CBS News reported conflicting accounts of oil flow through Saudi Arabia's East-West pipeline after a new strike. Actual damage is unconfirmed, so these remain claims, not verified facts.
Why the Red Sea Route Matters
With Hormuz largely shut, Saudi Arabia has been sending crude through its 1,200-kilometer East-West pipeline to Yanbu on the Red Sea. Exports through the Bab el-Mandeb strait rose from about 4.2 million barrels per day in 2025 to 7.4 million in June, according to Kpler data cited by FDD. Every barrel leaving Yanbu must pass through that strait, which carries roughly 7% of global oil output, per Tech Times.
The pipeline has already been tested. It went offline after a drone attack on September 11 and restarted on September 22, when Brent briefly slipped below $100, according to Modern Diplomacy. Al Jazeera reported the outage removed 4 to 5 million barrels per day, though Gavekal estimates the net loss at 1.5 to 2 million after other routes filled part of the gap.

From Oil to Stocks
Oil feeds inflation, inflation feeds yields, and yields drive stocks. The 10-year Treasury yield is at 5.18%, near multi-decade highs. Bloomberg data cited by Schwab show the odds of an October Fed hike falling from 47% on Tuesday to 20% by Friday after the weak jobs report. Even so, the S&P 500 lost 0.3% last week and the Dow 1.3%. On Monday, Dow and S&P futures were fractionally lower, Nasdaq-100 futures were down 0.1%, and France's CAC fell 0.6%, according to Yahoo Finance.
What to Watch Today
Watch whether tankers keep leaving Yanbu, whether any confirmed damage emerges, and whether Brent holds above $100. On the calendar, the ISM Services PMI is due today, a $39 billion 10-year Treasury auction on Tuesday, and Fed minutes on Wednesday.
What This Means for You
Oil headlines can move markets quickly, but unverified claims often fade. Long-term investors are better served watching confirmed supply data, such as tanker traffic and pipeline flows, than reacting to each report. If the Red Sea route is disrupted for real, expect energy costs, inflation expectations and bond yields to react together.
