Iran-US ceasefire proposal reopens Strait of Hormuz to commercial shipping

WHAT HAPPENED Iran and the United States have received a proposal for a 45-day ceasefire that would include reopening the Strait of Hormuz to commercial shipping. The proposal represents the first credible diplomatic channel for reducing tensions around the world's most critical energy chokepoint, through which approximately 21% of global petroleum liquids transit daily.

CHOKE-SHIPPING-001 reversal activates: credible ceasefire proposal reduces tail-risk premium embedded in energy prices and shipping costs. The mechanism transmits through war risk insurance repricing (current premiums estimated 0.5-1% of hull value for Hormuz transit) → tanker charter rates normalise as rerouting via Cape of Good Hope becomes unnecessary → energy spot prices decline as 17-million-barrel-per-day flow capacity reopens → broader risk-off positioning unwinds across commodities and defensive assets.

Brent crude: vulnerable to 8-15% decline as geopolitical premium compresses from current $107.41 levels. WTI: sympathy move lower from $99.94, though US domestic exposure limited. TLT: risk-off unwinding pressures duration assets at current $85.43. Tanker equities (DHT, FRO, EURN): charter rates normalisation headwind. GLD: geopolitical hedge demand retreats from elevated $418.27. Long Asian refiners (Chinese independents) benefiting from cheaper crude imports.

MEDIUM. Proposal stage suggests serious diplomatic engagement, but implementation timeline and verification mechanisms remain undefined. Market repricing ahead of confirmed agreement carries reversal risk if negotiations collapse.
