Brent crude rose to $117.42 a barrel on Friday, Oct. 23, its highest level since April. Renewed tensions in the Middle East have raised concerns about energy supplies and shipping security, while U.S. stocks and Bitcoin had already come under pressure. The oil rally has also put inflation risks back in focus.
Houthi attack raises shipping concerns
The latest leg higher in oil prices followed an attack on Saudi Arabia by Iran-backed Houthi forces. As the conflict intensified, Saudi Aramco evacuated its headquarters. An oil spill near the United Arab Emirates added to concerns about shipping security in the region.
Markets are watching for signs that a prolonged or wider conflict could disrupt crude shipments or supply. Available information has not established the spill’s impact on actual supply, leaving the outlook for prices dependent on how the situation develops and whether transport routes are affected.
Possible U.S. action against Iran remains uncertain
A broader source of uncertainty is the possibility that the United States could resume military action against Iran. Reports have described plans by the U.S. and Israel for potential strikes after the U.S. midterm elections, with energy infrastructure among the possible targets. The White House has said there will be no attack before the vote. Planning does not mean an operation is certain to take place.
For now, markets are weighing heightened geopolitical risk rather than a confirmed military operation. Any escalation could put energy facilities or transport routes at greater risk, but whether the reported plans are carried out remains unclear.
Nasdaq falls 2.6%; Bitcoin nears $81,400
Oil’s advance came as risk assets were already weakening. On Thursday, the Nasdaq fell 2.6% and the S&P 500 lost 1.2%. Concerns about heavy spending on artificial intelligence were a key factor behind the tech sell-off, while higher energy costs added another pressure point.
Bitcoin briefly fell toward $81,400, with liquidations approaching $441 million. Rising oil prices may sharpen concerns about inflation, but they do not by themselves explain losses in stocks and crypto. Worries about technology companies’ spending, position adjustments and Middle East tensions all weighed on risk appetite.
Brent now stands at $117.42 a barrel, near its high for the year. Investors are focused on whether the conflict widens, whether shipping is disrupted and whether the United States takes action after the election. The reported military planning remains distinct from a confirmed strike.
