What to know about the Jones Act as Trump considers a waiver during the Iran war

The administration is considering a temporary waiver of the 1920 Jones Act to ease domestic shipping disruptions amid the U.S.-Israel war with Iran; crude is trading around $100/bbl (vs. roughly $70 pre-war) and the U.S. national average for regular gasoline is about $3.63/gal, up $0.69 from a month ago. Analysts estimate a Jones Act waiver would only modestly lower East Coast pump prices (≈$0.03/gal) while potentially increasing costs elsewhere and harming U.S. shipbuilders and crews. Broader supply actions include the IEA's 400 million-barrel release and the U.S. plan to draw 172 million barrels from the Strategic Petroleum Reserve over 120 days, measures likely to provide short-term relief if the conflict continues.

Analysis

A temporary easing of U.S. cabotage constraints will primarily act as a liquidity shock to domestic freight markets: expect spot voyage rates for coastwise product moves to compress first, with rate discovery occurring in the 2–6 week window as foreign tonnage redeploys. That transmission will not materially shave national pump prices — the near-term effect is concentrated on transport margins and refinery feed flexibility, where I estimate a 30–150 cent/bbl swing in delivered feedstock cost for specific coastal refinery-to-market pairs, not the nationwide retail price.

Second-order winners are owners of international product tankers and VLCCs that can reallocate tonnage without long lead times; they capture incremental utilization and freight revenue while U.S.-built tonnage and crewing providers see utilization and pricing pressure. Conversely, firms exposed to long-term government-backed shipbuilding and crewing (both public and private) face multi-year demand loss risk, which amplifies political and legislative tail risk that could force a reversal within months.

Operationally the window to capture value is short and event-driven: key catalysts include the formal waiver notice, scope/route language, start-dates for voyages, and any Congressional/union countermeasures; each can swing outcomes sharply inside 30–120 days. Market-makers should treat positions as binary with skewed asymmetry — upside from enacted, sustained loosening; downside if reversal occurs quickly because protected incumbents lobby successfully — making option structures and tight hedge ratios the preferred implementation choice.

Key Decisions for Investors

• Pair trade (30–90 day): Long EURN 3-month OTM calls (buy 1.5x notional) vs short MATX (MATX) 10% notional. Rationale: capture foreign tanker utilization upside while hedging systemic shipping risk. Risk/Reward: ~1:4 asymmetric if waiver enacted; stop-loss on MATX at 8% and cut calls if waiver not issued within 45 days.
• Directional long (60–180 day): Buy PBF Energy (PBF) equity 3–5% weight. Rationale: East Coast refiners can flexibly improve feedstock logistics and capture margin uplift; expected upside ~20–40% if coastal differentials normalize. Risk/Reward: target +30% with 15% stop; downside if global crude collapses or SPR release widens heavy crude availability.
• Short structural (3–12 month): Reduce exposure to US-focused shipbuilders/crewing plays (PHLY or small US maritime caps) by 5–7% of portfolio or hedge with long-dated put protection. Rationale: durable demand destruction for protected domestic freight flows; Political reversal is likely but takes months. Risk/Reward: protect market value while collecting carry on hedge.
• Tactical derivatives (0–60 day): Buy front-month RBOB gasoline call spread (60-day expiry) to hedge a short-dated supply disruption continuation scenario. Rationale: if logistical flexibility is slower than markets expect, refined product tightness can spike retail prices. Risk/Reward: limited premium outlay with >3:1 payoff-to-cost if a supply shock re-intensifies.
