Standard Risk Global

The two-week US-Iran ceasefire announced Tuesday night triggered the sharpest single-day oil decline since 2020, with WTI crude plunging 14.9% to $96.14/bbl and Brent falling 13.8% to $94.16/bbl. Global equities surged in response — the S&P 500 rose 2.51% to 6,782.81, the Dow gained 2.85% (+1,325 points to 47,909.92), and KOSPI leapt 6.87% — as markets priced in the reopening of the Strait of Hormuz. For Chinese firms sourcing ~40% of seaborne crude through Hormuz, this is a consequential but precarious reprieve.

Iran's agreement to allow safe passage through the Strait came less than two hours before Trump's deadline threatening strikes on Iranian civilian infrastructure. While the headline relief is real, the operational reality is sobering: ship traffic through the Strait has not recovered above the handful of daily transits maintained during the five-week conflict, and tanker insurers have yet to lift war-risk surcharges. Oil at $96/bbl remains ~37% above pre-war levels of ~$70, meaning the ceasefire has repriced the tail risk but not the structural supply disruption.

For Chinese corporates, the calculus is nuanced. Beijing's strategic petroleum reserves and pipeline diversification (via Russia's ESPO and Central Asian routes) provided a partial buffer during the crisis. But ~40–50% of China's seaborne crude imports transit Hormuz, representing approximately $180 billion in annual energy trade. Any breakdown in the ceasefire would instantly re-expose this vulnerability. Gold surged 3.2% to ~$4,800/oz, signaling that safe-haven demand persists despite the risk-on rally — markets are hedging the fragility of the deal.

Watch in 48–72 hours: Iran's draft protocol with Oman on Strait traffic monitoring is the key verification mechanism — failure to implement would unwind the rally. Base case (60% probability): ceasefire holds, oil settles in the $90–100 range as supply chains gradually normalize. Risk scenario (30%): Israel's continued Lebanon operations complicate Hormuz transit, sending Brent back above $110. Action for corporate treasury: Lock in fuel hedges at current levels; the ceasefire window is optimal for extending crude purchase agreements at sub-$100 pricing before the deal's durability is tested.
