Middle East conflict tightens oil markets and disrupts global supply chains

Oil inventories globally are falling at a record pace, with IEA data confirming months of continued decline as the Iran conflict keeps vital supply routes disrupted. Satellite imagery shows Iran's main export terminal (Kharg Island) at a standstill over recent days, marking the first prolonged halt since the war began. Indian refiners are grappling with a potential forced scale-back of Russian crude imports if a US sanctions waiver lapses. Turkey's foreign reserves depleted at record pace in March, and Indonesia's rupiah hit record lows as hard-rate-hike expectations pile up. Meanwhile, energy importers globally are facing margin pressure; Europe is becoming increasingly reliant on US LNG, and Japan is shifting back to coal as LNG prices spike.

Copper, aluminum, and other industrial metals are tightening as supply chains stall. India has hiked gold and silver import tariffs to defend its currency. Fertilizer costs have surged; India booked diammonium phosphate at 40% above pre-war prices. The World Food Programme is warning of food-security risks, with Malawi cited as an extreme example of the impact on farmers dependent on stable fertilizer costs. Global shipping routes are congested; an Iran-linked LPG tanker sailed past the US Navy's announced blockade line, signalling the conflict's complexity and unpredictability.

Regionally, the Middle East premium is reshaping how global investors view the region. Geopolitical resilience now outweighs economic growth as a draw for capital; Mideast markets are diverging, with resilient economies attracting selective inflows while vulnerable ones bleed assets. The ECB is warning of stagflation, and commodity-heavy regions like the Gulf are seeing record resource depletion and currency pressures. US Treasury yields have risen, corporate credit spreads are widening, and junk-rated borrowers are rushing to refinance while demand is still strong.

Sceptics argue that the blockade will not persist indefinitely and that alternatives (Saudi output, US LNG, strategic reserves releases) can mitigate supply shocks over time. However, the multi-month outlook for continued disruption is now the base case, and geopolitical risk premiums are sticky. If the conflict broadens or spreads to new flashpoints, the energy shock could deepen significantly.
