Hürmüz Strait Remains Closed Until Sanctions and Blockade Are Lifted

The reopening of the Hürmüz Strait, a pivotal conduit for regional trade and energy flows, remains uncertain as existing sanctions and the blockade continue to impede its operational status.

Economic Cost of Sanctions and Blockade

■$30 billion in annual oil transits rely on the Hürmüz Strait; restrictions could cut this flow by 15%.

■About 20% of regional export volume has been rerouted to alternative corridors, raising transport costs by 8‑10%.

■International banks are forced to allocate roughly $1.2 billion for additional compliance budgets.

Strategic Significance for Regional Trade

■The Strait serves as a critical maritime corridor for 45% of the Middle East‑North Africa (MENA) region.

■Its closure could delay 30% of LNG shipments, creating 2‑3% volatility in global energy prices.

■Rerouting via the Gulf and Bab‑el‑Mandeb adds an average 7‑10 days to vessel transit times.

Market Participants' Expectations and Risk Perception

■Banks are considering a 0.5‑basis‑point risk premium when repricing credit exposure linked to the Strait.

■Insurers forecast premium hikes of 12‑15% for maritime coverage in the region.

■Investment funds anticipate a $5 billion capital inflow delay of 3‑6 months before committing to the area.

Policy Makers' Possible Scenarios

■Full Sanctions Relief: A softening of EU and US sanctions on Iran could enable the Strait to operate at full capacity, boosting trade volumes by 25%.

■Partial Opening: A limited schedule allowing only humanitarian aid and low‑risk cargo would deliver a modest 5‑7% economic benefit.

■Continued Blockade: Maintaining the status quo would deepen regional liquidity strain and could trigger a 3‑4% decline in the BIST‑100 index.

Kerem Tufan – Director of Commercial Loans and Central Bank Policies: The delayed reopening of the Hürmüz Strait tightens external trade financing for SMEs and raises risk weights in banks' loan books. The Central Bank must embed a flexible liquidity buffer to absorb regional trade shocks; otherwise, the commercial credit growth rate could fall from the current 3.2% to 1.5%. Strategically, policymakers should craft short‑term measures that balance immediate trade relief with long‑term energy security and financial stability.
