Oil climbs nearly 5% and chip stocks fall as US-Iran conflict widens on July 13

Summary

Brent crude climbed as much as nearly 5% in early trading on July 13 as Iran and the US exchanged strikes and Iran again claimed control of the Strait of Hormuz. WTI crude was trading around US$74.51/bbl, held below US$75 despite the geopolitical spike by OPEC+ supply increases and softer structural demand. US stock markets fell: chip companies and AI-sector stocks led losses, with SK Hynix among the heaviest decliners. Trump's announcement that he was reinstating what he called an Iranian blockade on Iranian shipping through the Strait of Hormuz amplified both oil moves and equity pressure. Oil prices pulled back from their early session highs before the close, suggesting markets were pricing ongoing conflict rather than immediate supply interruption.

The split

CNBC led with the equity angle: chip stocks and AI-sector declines were the dominant Wall Street story, with the oil spike treated as the catalyst. FX Leaders offered the tightest price analysis, flagging that WTI's failure to break US$75 despite the conflict was itself a signal that supply-side factors were limiting the war premium. Canadian broadcasters CP24 and BNN Bloomberg carried the same AP/wire summary, reflecting North American energy-market interest in Hormuz disruption risk.

By the numbers

• 5%, maximum intraday rise for Brent crude on July 13 before paring gains.
• US$74.51/bbl, WTI crude price on July 13 per FX Leaders.
• US$75/bbl, the resistance level WTI failed to break despite Hormuz tensions.

Why it matters

The Strait of Hormuz carries roughly a fifth of global oil supply. Even partial disruption, or credible threat of one, moves energy prices worldwide and feeds into headline inflation. The chip stock sell-off alongside the oil move shows markets are reading the conflict through two lenses at once: supply-shock risk for energy, and continued technology-sector weakness amplified by SK Hynix as a proxy for AI-memory demand. The divergence between a modest oil rally and a larger equity sell-off suggests financial markets see geopolitical risk as manageable for now, but demand-side headwinds as more structural.

What to watch

• Whether Brent crude breaks above US$80/bbl if the Strait of Hormuz disruption becomes physical rather than rhetorical.
• SK Hynix's share price as a leading indicator for global AI-chip demand sentiment.
• OPEC+ response: whether members accelerate or pause planned production increases given the Iran conflict premium.
