US-Iran ceasefire extended as oil whipsaws on Hormuz uncertainty
Hormuz infrastructure damage is structural — oil inflation persists for months regardless of diplomatic outcome, and rate policy cannot fix a supply shock.
Signal read
- Global oil supply fell 10.1 mb/d in March — largest single-month loss on record
- Hormuz throughput cut from 20+ mb/d to 3.8 mb/d by Iran war attacks
- WTI near $95 — down from $130+ peak, up 51% year-on-year
- Global oil inventories fell 85 mb in March alone
- Lloyd's war-risk premiums: 0.5-1.5% hull value per voyage — adding $2-4/barrel to landed crude costs independent of spot price
The ceasefire paused the escalation but cannot reverse the physical damage to Hormuz shipping infrastructure.
The oil inflation overhang is structural — it persists for months even after diplomatic resolution, constraining the Fed regardless of outcome.
Tanker insurers have repriced Hormuz route risk to levels not seen since the 1980s tanker wars. War-risk premiums of 0.5-1.5% of hull value per voyage have been reported in Lloyd's market, adding $2-4 per barrel to landed crude costs independent of spot price. Shipping operators rerouting via Cape of Good Hope add 10-14 days per voyage and $300-500k in incremental fuel and time costs — costs that flow directly into consumer prices through transport and manufacturing inputs.
Airlines and chemical producers face the sharpest margin compression. Jet fuel contracts renewing now are settling 40-50% above 2024 equivalents with limited hedging availability at current forward prices. The unambiguous beneficiary is the US domestic energy producer: shale is structurally profitable at $60 WTI, making every barrel above that a windfall attracting reinvestment and production growth that partially offsets the global supply gap.
Rate policy cannot fix a supply shock — Hormuz throughput doesn't increase when the Fed tightens.
