Brent's $100 Reset Hands China the Asymmetric Bill for a Half-Closed Hormuz

Brent crude jumped 3% to settle at $104.21/bbl on May 11 as the US-Iran ceasefire frayed and the Strait of Hormuz entered its eleventh week of partial closure. The IEA estimates 14 million barrels per day are still impaired - and China, which routes 47% of its crude imports through the chokepoint, is now absorbing the steepest second-order cost of any major economy.

What Happened

WTI closed at $98.07/bbl (+3%) on fresh strikes between US and Iranian forces near the Strait, even as both sides claim the ceasefire holds. US equities shrugged off the move - the S&P 500 ticked up to 7,412.84 (+0.19%) and the Dow added 0.19% to 49,704 - while the DXY slipped below 99 and the offshore yuan strengthened to 6.79/USD ahead of the Trump-Xi summit scheduled for May 14-15 in Beijing. Gold consolidated at $4,699/oz; the 10-year UST yields near 4.35%.

Why It Matters

This is a textbook asymmetric shock. The US imports 7% of its crude through Hormuz; China imports 47%, India 42%, and the Northeast Asian refining triangle (Japan/Korea/Taiwan) above 60%. Sovereign credit implications are diverging: oil-importer EM spreads have widened 15bps on 5Y CDS while US IG remains anchored. For Beijing, every $10 sustained rise in Brent translates into roughly $40 billion in incremental annual import cost - a meaningful drag on the current account at a moment when the PBoC is trying to anchor RMB expectations into the summit.

China & Global Angle

Chinese oil majors have already redirected VLCC flows toward Russian ESPO and West African grades, lifting freight rates 22% YoY. State-owned refiners are drawing down SPR at the fastest pace since 2022. For outbound Chinese firms - particularly in petrochemicals, shipping, and Belt-and-Road infrastructure exposed to Gulf logistics - this is the moment to revisit pricing pass-through assumptions and FX hedge ratios on USD-denominated input costs.

Forward Look (48-72 Hours)

Watch: (i) Trump-Xi communique language on energy cooperation and tariff truce extension (May 14-15); (ii) IEA monthly oil market report (May 14); (iii) any Iranian announcement on tanker traffic protocols. Base case (55%): Brent ranges $95-110 as Hormuz remains in "managed disruption" mode. Tail risk (20%): Full closure pushes Brent above $130 within 30 days. Action: Corporate treasurers should lock 6-month USD oil hedges and stress-test inventory financing at $120 Brent.
