Iran war could push inflation higher this year, Goldman Sachs says

Goldman Sachs projects Brent averaging $105/bbl in March and $115/bbl in April under a 6-week Strait of Hormuz disruption, with adverse peaks of $140/bbl (10-week disruption) and $160/bbl (10-week plus infrastructure damage). The firm raised its 12-month recession probability to 30%, trimmed 2026 GDP growth to ~2.1% Q4-on-Q4 (2.4% full-year baseline), and lifted December 2026 PCE inflation by 0.2pp to 3.1% (core PCE to 2.5% baseline). Goldman still models two 25bp Fed cuts in Sept and Dec but increased the chance the Fed stays on hold this year (20%→25%), reflecting upside inflation and risk to policy ease.

Analysis

A Gulf-centered disruption morphs the oil market from a demand story into a genuine supply shock, steepening near-term risk premia and increasing realized volatility across energy, freight and fertilizer markets. That combination both lifts marginal producer cashflows and simultaneously raises input costs for energy-intensive manufacturers and trade-exposed service sectors, creating diverging corporate winners and losers within a 3–12 month window.

Second-order transmission will be non-linear: shipping insurance and rerouting raise effective delivered fuel costs for Asia-Europe and intra-Asia trades, while fertilizer price pressure amplifies food-price pass-through into core services via higher agricultural input bills. EM importers with limited FX reserves and heavy food/fertilizer import dependence will see sharper real activity hits, pressuring sovereign spreads and creating idiosyncratic default/roll risk in the 6–18 month horizon.

Market microstructure will matter more than headline levels — backwardation will reward producers and short-tenor hedges, while curve steepening/flattening dynamics will hinge on whether the shock is transitory or permanent. Options vol and cross-asset correlations will increase, so pure directional positions carry asymmetric risks unless paired with calendar or FX hedges.

Key catalysts to watch: tactical disruption events and insurance/shipping-cost signals in the next 0–3 months, OPEC+ and US shale production responses over 3–6 months, and inflation-expectation metrics plus Fed communication over 6–12 months; diplomatic de-escalation or rapid SPR coordination are the highest-probability reversals within weeks to months.

Key Decisions for Investors

• Long US small-cap E&P basket (PXD, FANG, DVN) — 6–12 month horizon. Buy equal-weighted positions, size to 2–3% NAV. Hedge tail risk by purchasing 6-month 20–30% OTM puts on the basket or buying WTI puts; expected asymmetric payoff if supply disruption persists, downside limited by hedges.
• Pair trade: long refiners (VLO, MPC) / short major airlines (DAL, AAL) — 3–6 months. Refiners benefit from product-crack expansion while airlines suffer fuel cost pass-through; target 20–40% gross return if cracks widen, stop-loss pair if Brent futures drop back and cracks compress by 30%.
• Options calendar spread on WTI (buy near-month call, sell 6–12 month call) via USO or futures — tactical 0–3 month trade. Captures front-month risk premium under disruption (limited premium outlay) while monetizing mean reversion risk in longer months; max loss = net premium, tail upside if disruption extends.
• Inflation hedge: overweight 5–10y TIPS (TIP) vs underweight nominal 5–10y Treasury (IEF/TLT) — 6–12 months. Protects portfolio purchasing power if energy-driven headline inflation persists and Fed delays easing; watch real yield moves and cap duration exposure to limit nominal rate risk.
