Middle East Escalation Reprices Oil as Korea Export Boom Sharpens Divergence

Oil climbed over 2% Sunday and into Monday trade as Israeli forces advanced into southern Lebanon and Iran asserted sovereignty over the Strait of Hormuz after a U.S. naval presence redirected more than 100 vessels. According to multiple reports, the IRGC claims control over the waterway even as Trump administration officials say interim peace talks "will work out well." The Financial Post and Economic Times both note that hope for a permanent U.S.-Iran ceasefire remains elusive, and analysts warn that any prolonged closure of Hormuz would tighten global crude supply materially.

The geopolitical repricing coincides with a sharp divergence in Asian manufacturing. South Korea reported export growth hit a four-decade high in May, driven by an AI semiconductor boom that continues to run well ahead of consensus. Reuters highlights that chip shipments remain the primary driver, reinforcing the thesis that AI capex has not yet rolled over despite broader macro softness.

China, meanwhile, saw its official manufacturing PMI slip to 50.0 in May from 50.3 in April, matching the threshold between expansion and contraction. The Economic Times attributes the slowdown to a five-day holiday disruption, weaker global demand, and rising input costs. The reading met economist expectations but underscores the uneven recovery across the region.

Elsewhere in the South China Sea, Beijing conducted what it called combat readiness patrols near Scarborough Shoal, though Philippine authorities dismissed the drill assertions as unfounded. The activity followed joint U.S.-Philippine maritime exercises in the same waters. In Eastern Europe, Ukrainian President Zelensky warned that intelligence suggests Russia is preparing a major assault imminently, adding another vector of geopolitical risk to a tape already weighing energy supply and semiconductor demand.

The pattern is familiar: energy reprices on supply risk, semiconductors reprice on AI demand, and China sits at the expansion line while Korea runs. The divergence is the read.
