Goldman Sachs says oil flows through Strait of Hormuz down sharply

Oil flows through the Strait of Hormuz have plunged to ~0.5 mbpd from 19.5 mbpd (an estimated reduction of ~17.2 mbpd after pipeline redirection), triggering a sharp oil-price shock and contributing to a three-week market losing streak. Oil-linked securities rallied (BNO +12% over the past week to $49.04; YTD +73%), while Goldman cut its 2026 Q4/Q4 GDP growth forecast by 0.3ppt to 2.2% and now sees Brent averaging $98 in Mar–Apr with a $110 upside if disruptions persist; BofA advises selling above $100. Morgan Stanley now estimates 0–2 vessel transits/day (vs prior 2–6) amid AIS spoofing, leaving recovery timelines skewed toward delays and sustaining volatile, risk-off market conditions.

Analysis

The market is treating this as a supply shock priced into crude and maritime risk premia, but the true transmission to global demand and bank P&L will be non-linear and concentrated. Expect shipping / freight rate dislocations to persist for weeks even if crude flows resume: rerouting adds voyage days, insurance premiums and layup cycles create a multi-week lag between tanker earnings reversion and physical flow normalization.

Banks and trading desks face two offsetting channels over the next 1–3 months — higher realized oil drives trading volumes and commodity revenues, while inflationary impulse and growth drag compress credit fundamentals later. For large universal banks, mark-to-market trading gains can be front-loaded into quarterly P&L, but underwriting and merchant banking exposure to energy and EM clients create 2–6 month tail risk to loan-loss provisioning.

The option market is signaling asymmetric outcomes: a sustained disruption (>30 days) rapidly elevates crude to the regime where demand elasticity bites and policy responses become likely, compressing upside; a short, forceful naval/escort-led reopening would produce a violent mean reversion. Because AIS data integrity is compromised, on-chain signals (charter fixtures, insurance notices, bunker liftings) will matter more than vessel counts for front-running flow recovery.

Near-term technicals favor volatility trades and directional crude exposure sized to event risk rather than capital deployment into cyclicals; medium-term, watch consumer gasoline elasticity and central bank messaging — if CPI momentum reaccelerates, defensive duration and credit hedges should be reallocated into the trade plan within 2–3 months.

Key Decisions for Investors

• Tactical long crude-vol: Buy a 1–2 month Brent/WTI straddle (e.g., Jul WTI options) sized for a 5–8% move in spot; set a 40–50% profit target and 50% trailing stop. Rationale: event uncertainty and AIS spoofing create asymmetric upside in realized vol over weeks.
• Directional oil exposure with capped downside: Long BNO sized as 2–4% portfolio exposure with a protective call sell (covered call) at a strike ~10–15% above current—time horizon 1–3 months. R/R: captures price upside from flow disruption while monetizing carry to reduce theta decay risk.
• Shipping freight capture: Long selective tanker owners (e.g., STNG or FRO) for 3–6 months to capture elevated rates from rerouting; size modestly (1–2% portfolio) and hedge with a 3-month put to limit drawdown if flows normalize quickly. R/R: upside from spot TC rates, downside cushioned by hedged premium.
• Relative bank pair: Long BAC, short GS for a 3-month horizon (equal notional) — BAC benefits from higher-rate NII and more retail diversification while GS is more exposed to trading gyrations and downward GDP revisions. Use 3-month OTM puts on GS to cap left-tail risk; target relative outperformance of 300–500bps.
• Policy/hard-landing hedge: Buy 2–3 year TIPS or a steepening swap receiver for 3–6 months if oil-driven CPI re-accelerates; alternatively, allocate 1–2% to CDS protection on high-exposure oil & gas loan portfolios if evidence of worsening corporate cash flow emerges. R/R: small insurance cost for asymmetric protection against stagflation.
