Most of Wall Street points to high oil prices as the driver of inflation. A maverick Johns Hopkins economist says they’re chasing the wrong culprit

March CPI rose 3.3% year over year, with the article arguing that elevated oil prices from the Iran/Strait of Hormuz conflict are contributing to the hot reading. Steve Hanke counters that the real driver is excessive money supply growth, citing bank credit growth of 6.6% in February and warning inflation was already accelerating before the war. The piece frames inflation as likely to remain above the Fed’s 2% target even if oil prices later fall.

Analysis

The key market implication is that the inflation impulse may be more persistent than a geopolitical shock typically implies, because the relevant driver is credit creation with a lag rather than the commodity spike itself. That makes the right trading horizon months, not days: energy can mean-revert quickly if the conflict de-escalates, but the inflation-sensitive parts of the curve and rates vol can keep repricing if bank lending stays firm. In other words, the market may be overestimating how fast CPI can roll over even if headline gasoline prices soften.

The second-order winner is not just energy producers, but any asset whose cash flows improve when nominal growth stays elevated and real rates remain sticky: banks with net interest margin support from higher nominal activity, short-duration credit, and certain commodity-linked equities. The more vulnerable cohort is duration-sensitive growth, housing-adjacent names, and rate-dependent leverage in smaller caps, because a persistent inflation print forces a higher-for-longer policy regime even without fresh oil shocks. If the consensus is treating this as a one-off supply event, it is underpricing the risk that services inflation and wage pass-through remain sticky into summer.

The contrarian edge is that the market may be misallocating the cause of inflation, but not necessarily the near-term direction of the rate move: if the public narrative remains war-driven, any de-escalation could trigger a relief rally in energy and a temporary dip in breakevens while policy expectations stay tight. That creates a window to fade the most obvious oil hedge and express the view through instruments tied to persistent monetary conditions rather than spot commodities. The main reversal risk is a rapid tightening in bank credit, which would hit the inflation thesis with a 2-4 quarter lag and could flatten the trade quickly.

Key Decisions for Investors

• Short XLY vs long XLF for the next 2-3 months: persistent inflation keeps nominal rates elevated, supporting banks more than consumer discretionary; risk/reward improves if credit growth remains positive and energy retreats.
• Buy 3-6 month payer swaptions or use TLT puts as a hedge against sticky inflation: this is a cleaner expression than outright oil longs if the market is underpricing the lagged monetary effect.
• Short IWM against long SPY over 1-2 quarters: smaller caps are more rate-sensitive and less able to pass through input costs if inflation stays above target, while large caps have better pricing power.
• Fade the most crowded energy beta with a tactical short in XLE or USO on any war-de-escalation headline, but keep the position time-limited to days/weeks because the structural inflation backdrop can keep oil support bid.
• Prefer long-duration value over rate-sensitive growth: initiate a pair long JPM / short ARKK for 1-2 quarters; if lending stays firm, the market will reward financials' nominal exposure and punish high-multiple duration assets.
