US-Iran Tensions Disrupt Strait of Hormuz Shipping

The escalation of US‑Iran tensions in the Strait of Hormuz has instantly pressured global maritime transport and energy prices.

Sharp Decline in Strait Traffic

According to Kpler data, vessel transits fell from a pre‑conflict 130 daily average to 15, a drop of over 90%. A brief recovery after the June 14 agreement saw traffic rise to 70 vessels daily, but renewed attacks have reversed that gain.

■130 vessels daily (pre‑conflict) → > 90% decline

■70 vessels daily (post‑agreement) → short‑term rebound

■9 commercial vessels on July 15, versus 13 the day before

US Economic Levers and Reactions

President Donald Trump announced a 20% transit fee on all ships passing the strait. The move drew sharp criticism from Hapag‑Lloyd and UTİKAD chairman Bilgehan Engin, who warned that the fee undermines predictability across global supply chains.

■Hapag‑Lloyd: “Charging for passage through international waters is fundamentally wrong.”

■UTİKAD Chairman Bilgehan Engin: “Risk analyses must be updated; insurance premiums will rise.”

Market Implications and Risk Premiums

Heightened geopolitical risk is pushing freight rates upward, especially for energy and raw‑material shipments. Insurance and war‑risk premiums are climbing, feeding broader inflationary pressures worldwide.

■Increase in war‑risk and insurance premiums

■Upward pressure on freight rates

■Global inflationary pressures intensify

Markets view the 20% transit fee as a potential new cost floor for maritime shipping, likely inflating risk premiums and driving volatility in WTI and Brent futures. Investors should reassess short‑term exposures, as heightened risk premia could spill over into broader commodity and equity markets, amplifying inflationary dynamics globally.
