War risk pricing is moving in bursts this year. After fresh attacks and electronic interference warnings, additional premiums on key lanes have surged, softened, and surged again, turning a seven-day cover into a six-figure swing on larger ships. This report pulls the corridors together, shows the current pressure points, and gives fast tools to sanity-check voyage exposure.

War Risk Surcharge Heatmap 2025

Live corridors ranked by premium jumps after new advisories

Lower

Higher

Market signals (recent)

Red Sea often trades around the upper end of AP ranges during incident clusters; seven-day covers can reprice within days.
Strait of Hormuz lifted toward mid-range AP in June, eased later, remains headline-sensitive.
Israeli ports show sharp week-over-week step-ups when alerts increase.
GNSS/AIS interference advisories continue to feature in routing briefs.

Heads up

AP is negotiated per risk, ship and day. Ranges here are directional for planning; confirm voyage terms with your broker and underwriters before routing.

Corridor pressure board

*AP = Additional Premium for hull war per seven-day period. Ranges vary by hull value, flag, cargo, management, wording and voyage date.

Quick tools and timeline

AP cost snapshot

Hull value ($m) AP rate (% / 7 days)

Seven-day AP

$400,000

Per-day equivalent

$57,143

Formula: Hull × (AP% ÷ 100). Per-day = Seven-day ÷ 7.

Cape vs Suez quick check

Extra days via Cape TCE / Opex ($/day) AP on Suez lane ($) Fuel delta ($ via Cape)

Cape cost add-on

$800,000

Decision (lower is better)

Suez cheaper by $150,000

Rule of thumb: Cape add-on = Extra days × TCE + fuel delta. Compare with AP on Suez.

2025 flashpoints (selected)

June: Hormuz tensions lift AP toward mid-range; softening later with de-escalation headlines.
July: Red Sea casualties and sinkings; AP revisits upper band.
Early October: GNSS/AIS interference reported from Port Sudan to the Gulf; market remains headline-driven.

Sequence shows why quotes can whipsaw within a seven-day AP window.
