Oct WTI crude oil prices (CLV26) are up more than +3% today on concern that global oil supplies will get even tighter after Saudi Arabia closed a major pipeline following attacks, disrupting a key route that bypasses the Strait of Hormuz. Saudi Arabia closed the East-West pipeline late last week, which carries 7 million bpd of crude, as a precaution following attacks by Houthi rebels and gave no indication of when it will reopen. The pipeline moves oil away from the Persian Gulf toward the Red Sea, where it can be loaded on tankers. Saudi Arabia told OPEC last Thursday that its crude production in August fell to 6.238 million bpd, the lowest since 1990.
