Hormuz closure triples German factory shortages

The Strait of Hormuz has been closed to commercial shipping for three months. What started as a geopolitical crisis has become an industrial one. German chemical firms reporting material shortages jumped from 7% in April to 31.1% in May (Wiwo/ifo, 28 May). ifo economist Anna Wolf called the uptick in orders "temporary." Companies are bracing for prolonged disruption, and even a diplomatic breakthrough this week cannot quickly undo damage already done.

Insurance is what keeps the strait closed

On 5 March, the major P&I clubs (the mutual insurers covering crew, cargo, and environmental liability for nearly every commercial vessel) cancelled war-risk coverage for Hormuz (Property Casualty 360, March 2026). Without that cover, a ship cannot dock at any port. For vessels still attempting the crossing, hull war-risk premiums sit at 5.5% of vessel value. A single voyage on a large tanker now costs upward of $6 million in insurance alone (The Flow Weekly, 26 May).

So tankers and LNG carriers have shifted to the Cape of Good Hope, adding weeks to every journey. LNG transits through the Suez Canal have dropped by roughly 90%, according to shipping tracking data (Schiffsradar24.de). That rerouting ties up capacity worldwide and pushes freight costs higher even for cargo that never went near the Gulf.

Diplomacy has not caught up. Trump's Situation Room meeting on 29 May ended without a deal, and Tehran disputes his characterisation of the terms (PBS News, Al Jazeera). But signing something would only start the clock. Mine-clearance takes four to six months. Lloyd's would then need to reclassify the zone before insurers restore normal coverage. Full throughput before January 2027 is unlikely (LMA Lloyd's).

The €15 billion storage gap

Europe fills gas reserves during summer to prepare for winter heating. That process is badly behind. Germany's reserves sit at 30.6%, roughly half the 67% that is normal for late May (BDEW). The EU's energy regulator ACER estimates that closing this gap across Europe will cost an extra €10–15 billion (EMA Energiewelt). That money flows through utilities to households and industry as higher bills.

German factories are already cutting hours to ride out the supply shock. The ECB (the European Central Bank, which sets interest rates for the 20 eurozone countries) is expected to raise rates by 0.25 percentage points on 11 June. Markets price a hike at 91% probability (ECB Watch, Euronews). Borrowing costs are rising at exactly the moment when factories and households are losing money to energy bills.

The global buffer is thinning too. The IEA's 400-million-barrel strategic release is roughly 55% consumed, and the cumulative supply deficit could reach 900 million barrels by September (Brookings), just as summer driving and cooling demand peaks. Bypass pipelines through Saudi Arabia and the UAE carry only a fraction of what Hormuz handled before the crisis.

Rainer Seele, chairman of ADNOC XRG and a veteran of Gulf and European energy markets, put it plainly: "The recovery of supply chains will not come overnight. It will take months" (Tagesspiegel, 27 May). By autumn, every week of delay will show up in Europe's gas reserves.
