Brent Crude Spikes as Iran Ceasefire Delay Rattles Global Shipping Insurers

LONDON — Brent crude jumped more than four percent in early Asian trading on Sunday after Iran missed an unofficial deadline to respond to the U.S. ceasefire proposal, while Lloyd's of London quietly raised war-risk premiums on every tanker transiting the Strait of Hormuz to multi-decade highs. Analysts now warn that a sustained move above $95 per barrel would re-ignite the global inflation fight central banks thought they had won.

The Price Action

Front-month Brent settled the previous session at $87.40 and gapped to $91.20 on the Singapore open before easing to $90.55. WTI tracked in lockstep, and the Brent–Dubai EFS widened sharply, signalling acute concern about Middle Eastern barrels specifically rather than a broad demand shock.

Insurance Repricing

Lloyd's syndicates lifted hull-war additional premiums to 0.75–0.85% of vessel value for Hormuz transits, up from 0.25% a week ago. For a fully laden VLCC, that is an extra $1.6 million per voyage — a cost that flows almost entirely into the landed price of crude in Rotterdam, Singapore, and the U.S. Gulf.

The Inflation Channel

Goldman Sachs commodities desk now models that every $10 sustained increase in Brent adds roughly 35 basis points to U.S. headline CPI over six months and 50 bps in the euro area, where pass-through to pump prices is faster. That would force the Fed and ECB to delay the rate cuts both have signalled for the back half of 2026.

What to Watch

Three signals next week: SPR drawdown announcements from Washington, OPEC+ communication on spare capacity, and whether China — which has been quietly building strategic stocks at sub-$80 — steps in as a marginal buyer or a marginal seller.
