Iran War Closes Hormuz: Oil Rally Fuels Inflation Bets, Pressures Bonds

The Iran war has created a de facto supply shock that is no longer priced as temporary. The Strait of Hormuz, which handles roughly one-third of global seaborne oil trade, is effectively closed to normal shipping. Traders report that Vitol is now offering Iraqi crude outside the Hormuz corridor, a sign that some shipments are attempting alternative routes, but volume losses are substantial. Oil headed for a weekly gain near $75-80/bbl, with Brent holding elevated and WTI consolidating.

Dow CEO Jim Fitterling noted the company is "hardly moving anything" through Hormuz and estimated 275 days for supply normalization if the war persists. US inflation data is already hot (retail sales beat masked underlying pressure), and energy prices staying elevated mean that core inflation metrics will stick higher for longer, complicating the Fed's policy path.

If the Fed signals it will hold policy firm (Warsh's confirmation hints at this), mortgage rates should rise to reflect higher real yields. This mismatch creates risk: either rates gap higher suddenly (negative duration shock) or growth disappoints and we fall into a stagflationary trap (high inflation, low growth).

Energy exporters (Saudi Arabia, Brazil, Canada) are benefiting; energy importers (Japan, Europe, much of Asia) are facing margin pressure. Currency strength correlates with oil prices, so the dollar continues to rally on the war premium. Renewable energy investments face temporary headwinds (fossil fuels are more competitive at $75-80/bbl) but long-term energy security concerns could accelerate capex shifts.
