Goldman: Iran-related oil shock could shave 0.3% off global GDP and lift inflation

Goldman Sachs analysts say a spike in oil tied to the Iran conflict and interruptions in tanker traffic through the Strait of Hormuz could subtract about 0.3% from global growth over the next year and raise headline inflation by roughly 0.5-0.6 percentage points, with a smaller impact on core inflation of 0.1-0.2 percentage points. The bank views the shock as concentrated in energy markets but cautions that a prolonged or intensified disruption would worsen the economic hit.

Key Points

  • Estimated global growth impact: roughly -0.3% to global GDP over the next year - sectors affected include broad economic activity and GDP-sensitive industries.
  • Inflation effects: headline inflation up about 0.5 to 0.6 percentage points, core inflation up about 0.1 to 0.2 percentage points - consumer prices and sectors sensitive to input energy costs are impacted.
  • Supply-chain concentration: shock concentrated in energy markets rather than broad non-energy supply chains; non-energy exports from Gulf countries make up about 1% of global trade.

Goldman Sachs analysts estimate that a recent surge in oil prices associated with the Iran conflict could cut global economic output by about 0.3% over the coming year while exerting upward pressure on consumer prices.

According to the bank's updated outlook, higher energy costs would raise global headline inflation by approximately 0.5 to 0.6 percentage points. Core inflation, which strips out volatile energy prices, is expected to receive a smaller boost of roughly 0.1 to 0.2 percentage points. Those estimates reflect revisions to Goldman Sachs' oil and gas forecasts after supply disruptions tied to the conflict and interruptions to shipping through the Strait of Hormuz.

Goldman characterizes the current economic shock as largely concentrated in energy markets rather than spread across many supply chains. That distinction reduces the prospect of broad-based shortages like those that accompanied the pandemic-era inflation spike of 2021-2022, the bank said. In the present episode, the inflationary effects are projected to be mostly confined to energy-related sectors.

Energy prices have risen sharply as tanker movements through the Strait of Hormuz - a major artery for global crude shipments - have been disrupted during the conflict. The resulting jump in oil and gas prices is expected to weigh on economic activity worldwide while increasing consumer price pressures.

Goldman also points to limited trade exposure for most large economies to non-energy goods originating in the Middle East. Non-energy exports from Gulf countries represent about 1% of global trade, the bank notes, implying that broader supply chain disruptions beyond energy are likely to remain restrained.

Nonetheless, Goldman warns that the situation could deteriorate if the conflict intensifies or if the Strait of Hormuz stays closed for a prolonged period. Should supply interruptions become extended, oil prices could rise further, deepening the drag on global growth and keeping inflation higher for longer.


Summary

A Goldman Sachs analysis finds that an oil price spike tied to the Iran conflict and disruptions in the Strait of Hormuz could trim global GDP by around 0.3% and add roughly 0.5-0.6 percentage points to headline inflation, with a smaller 0.1-0.2 percentage point uplift to core inflation. The bank views the shock as concentrated in energy markets, though it warns of larger risks if disruptions persist or worsen.

Risks

  • Conflict escalation: a more intense Iran conflict could deepen energy-market disruptions and further raise oil prices, increasing stress on growth and inflation - risks concentrated in energy and consumer price-sensitive sectors.
  • Extended Strait of Hormuz closure: prolonged closure would amplify supply interruptions, potentially pushing oil prices higher and increasing the economic drag across global markets.
