The May Consumer Price Index came in at 4.2% year-over-year — the highest reading since April 2023. The number dominated financial headlines. Markets immediately priced in a higher probability of Federal Reserve rate hikes.
But buried beneath the headline number is a distinction that changes the entire analysis — and that most mainstream coverage is failing to make clearly.
This inflation is not driven by consumer demand. It is driven by a supply shock.
Energy costs surged 23.5% year-over-year in May, accounting for over 60% of the monthly CPI gain. Core CPI — which strips out food and energy — came in at only 2.9%, well below the headline and very close to the Fed’s target. The inflation problem in America right now is not broadly embedded in the economy. It is concentrated in energy — and energy is spiking because of the Iran conflict and the disruption to global oil flows through the Strait of Hormuz.
The International Energy Agency has characterized the 2026 Iran conflict as the largest oil supply disruption in the history of the global oil market.
Interest rate hikes do not open the Strait of Hormuz. They do not increase global oil supply. They do not resolve a geopolitical conflict. What they do — and this is the critical distinction — is address demand-driven inflation. Not supply-driven inflation.
To understand why this matters so deeply, it helps to understand how monetary policy works — and where its limits are.
The Federal Reserve’s primary inflation-fighting tool is the interest rate. When inflation is demand-driven — when consumers are spending too much, bidding up prices across the economy — raising rates makes borrowing more expensive, slows spending, reduces demand, and eventually brings prices down. The mechanism works because the inflation is being caused by something rates can influence: the cost of credit.
Supply-driven inflation is different. When prices rise because a critical commodity is not available — because a shipping lane is blocked, because a war has disrupted production, because a natural disaster has constrained output — raising rates does not increase supply. It simply makes everything else more expensive as well. Businesses face higher borrowing costs at precisely the moment their input costs are already elevated. Consumers face higher mortgage rates and credit costs on top of higher energy bills. The economy slows.
Meanwhile, the supply shock continues. The inflation driven by the supply shortage does not respond to higher rates because higher rates do not produce more oil.
This is the mechanism by which supply-side inflation combined with monetary tightening has historically produced stagflation: an economy experiencing simultaneously rising prices and slowing growth, with a central bank unable to address either problem effectively without making the other worse.
The most instructive historical parallel for the current situation is the 1970s oil shocks — and it is one that the market appears to be underweighting significantly.
The 1973 OPEC embargo removed approximately 7% of global oil supply in a matter of weeks. Prices quadrupled. The Fed, facing an inflation problem it could not address with monetary tools alone, raised rates — slowing the economy without meaningfully reducing the supply-driven price pressure. Stagflation followed.
The 1979 Iranian Revolution sent oil prices from roughly $15 to over $35 per barrel. Again, the Fed raised rates — famously, under Paul Volcker, to levels that produced the worst recession since the Great Depression — in an attempt to break inflation that had become entrenched through years of supply shocks and monetary accommodation.
During both episodes, gold historically performed as a dual-purpose asset: an inflation hedge when currencies lose purchasing power, and a safe-haven asset as confidence in the monetary system’s ability to address the crisis declined. From 1971 to 1980, gold rose from $35 to over $800 per ounce — a gain of 2,300%. That reflected both currency debasement and the tendency for gold’s value to rise when paper currencies lose real purchasing power.
The IEA has characterized the 2026 Iran conflict as the largest oil supply disruption in the history of the global oil market. The scale of the current disruption exceeds, by the IEA’s assessment, even the 1973 embargo. The monetary policy response — rate hikes into a supply-driven inflation environment — is structurally identical to what occurred in the 1970s.
Past performance is not indicative of future results. The 1970s gold performance does not guarantee similar outcomes today. Economic conditions, monetary frameworks, and market structures differ in important ways. What history does provide is a framework for understanding the relationship between supply-driven inflationary shocks, trapped central bank policy, and gold’s historically demonstrated role as a store of value in those environments, with stagflation historically favorable for gold because it combines inflation pressure with economic stress.
The data from May 2026 paints an increasingly clear picture of early-stage stagflationary conditions.
Headline CPI at 4.2% — nearly double the Fed’s 2% target. Core CPI at 2.9% — close to target, revealing the headline as supply-driven. PCE inflation at 4.1% — the highest since April 2023. Core PCE at 3.4% — well above target. Consumer spending: +0.7% in May — consumers still spending. Personal income: +0.7% — incomes rising, but not keeping pace with energy costs in real terms. National debt: $39 trillion and growing. Annualized interest costs: $1.2 trillion.
The consumer is still spending, supported by income growth. But the energy cost surge is an external tax on every American household and business — one that neither the Fed nor Congress can eliminate with monetary or fiscal tools. That kind of shock also increases economic uncertainty and high inflation uncertainty, which can support gold demand as a hedge against purchasing power loss. It can only be addressed by resolving the underlying energy supply disruption.
Meanwhile, the Fed is signaling rate hikes. Higher rates on a $39 trillion debt increase the fiscal burden further. Higher mortgage rates and business borrowing costs add to the pressure on consumers already facing elevated energy costs. At the same time, market participants also reprice gold as inflation expectations shift, and gold’s price tends to rise during periods of broader macro stress because it reflects macroeconomic expectations related to inflation.
This is the stagflation setup. Not yet stagflation in its full historical expression — but the early indicators are present and the trajectory is concerning.
The current environment presents what may be an unusual dynamic for gold: it stands to potentially benefit from both possible outcomes.
If the supply-driven inflation persists and the Fed raises rates into a slowing economy — the stagflationary scenario — gold’s historical role as a dual inflation hedge and safe-haven asset may reassert itself, as it did in the 1970s. If economic growth slows, gold could rise 5% to 15% in 2026. In a severe downturn, gold may surge 15% to 30%.
If the Iran conflict resolves, energy prices fall, and inflation moderates — the rate hike narrative fades. Rate cut expectations return. The dollar softens. A weaker dollar and easing interest rates can support gold. Still, gold prices could drop 5% to 20% if economic growth accelerates materially. Historically, precious metals have performed well in easing monetary cycles, as the opportunity cost of holding non-yielding assets declines.
In either scenario, the structural backdrop — $39 trillion in debt, zero AAA ratings, central banks still accumulating bullion, and the long-term de-dollarization trend — remains fully intact. Demand from central banks significantly influences gold prices, and emerging markets remain key buyers through ongoing central bank buying that is expected to keep central bank demand above pre-2022 levels, with 2026 purchases projected at roughly 756t to 1,100t. Geopolitical risk and other frictions are expected to persist into 2026, which may keep official purchases firm amid supply shocks. Investor demand could also get added support from gold ETF inflows in 2026. More broadly, gold markets continue to reflect both geopolitical and economic uncertainty. As of mid-2026, high price levels have not changed the supply picture: mine output is expected to rise only modestly, declining ore grades and exhausted easy high-grade deposits are limiting new volume, inflation is lifting operating costs, and large projects still take 10 to 20 years to move from discovery to production. Gold is a finite asset, recycled supply has not surged as expected, and instability can disrupt mining supply chains and tighten physical availability.
The inflation the Fed cannot fix has created a unique setup. Gold’s potential role in navigating that setup is worth serious consideration.
