Tariffs and energy shocks are raising prices. That is not the same as a wage-price spiral

THE COMPETITION for alarmist inflation headlines has produced the "quadruple whammy" — a phrase borrowed from pandemic-era public health and repurposed to suggest that tariffs, Middle East oil shocks, broad-based inflation and artificial-intelligence-driven cost pressures are converging to destroy America's stock market. The stock market, for its part, is not paying much attention. The S&P 500 and the Dow Jones closed at record highs on August 4th, with the Dow pushing past 54,000 points for the first time. Since the 2024 election, the stock market has advanced more than 30%, driven by corporate earnings growth rather than rising valuations, according to U.S. Bank. Something about the alarm is not tracking.

The real question is not whether inflation pressures exist. They do. It is whether they have the structure of a wage-price spiral — the kind that forces central banks into painful tightening and sends equities into damage control. The evidence does not support that diagnosis. It supports something messier, more political and less dramatic: supply shocks that raise prices while a weakening labour market removes the feedback loop that would make them stick.

Tariffs are the most obvious pressure. After the Supreme Court declared the International Emergency Economic Powers Act an unlawful basis for tariffs in February 2026, the average applied tariff rate dropped from 15.2% to 8.2%. The administration rebuilt its wall using different legal foundations. A temporary 10% tariff under Section 122 of the Trade Act covered nearly all imports from February until its expiry in July. In its place came new Section 301 duties on more than 60 countries, sector-specific Section 232 tariffs on metals, autos and pharmaceuticals, and a Section 338 tariff on selected Canadian goods announced in August. The Tax Foundation estimates the average effective tariff rate for calendar year 2026 at 6.6%, the highest level since 1969.

These are not cosmetic. Tariffs are largely passed through to import prices and then to consumers; they act as a regressive tax. The Senate Joint Economic Committee estimates that the tariffs will increase building costs by $10,900 per home initially, rising to more than $17,000 in subsequent years. And the tariff trajectory is not settling: the Tax Foundation projects the weighted average applied tariff reaching 11.8% once the new measures take full effect.

The second pressure is energy. The war with Iran shut down the Strait of Hormuz, through which roughly a fifth of the world's petroleum passes. Between February and May, American fuel prices rose at the fastest pace in more than three decades. That shock briefly pushed headline CPI to 4.2% in May, the highest annual reading in three years. Then a ceasefire held in June, gasoline prices collapsed and the headline CPI fell 0.4% in a single month — the biggest monthly decline since April 2020. The annual headline rate dropped to 3.5% and core CPI, which strips out food and energy, eased to 2.6% from 2.9%, according to the Bureau of Labour Statistics.

But the ceasefire collapsed. The US reimposed a naval blockade of Iran in July and gasoline prices ticked back up. The energy component is a reminder that the underlying tension is unresolved, not that energy inflation is structural. The mechanism is clear: energy inflation in this episode is geopolitical. It can reverse just as sharply.

That brings us to the two supposed drivers the "quadruple whammy" needs in order to be dangerous: wages and housing. Neither is doing what alarmists expect.

Wage growth is below headline inflation. Average hourly earnings rose 3.5% over the year through June — equal to the latest headline CPI and well below the 4.2% peak. Real wages have been eroded at the margin, and the labour market is weakening, not heating up. June added just 57,000 jobs, with prior months revised down by 74,000. The unemployment rate held at 4.2%. Job losses in manufacturing, transport and mining — higher-wage sectors that had driven wage growth in the previous expansion — have accumulated since mid-2025. Wages are not about to feed a wage-price spiral. They are the part of the system that is losing.

Housing costs are rising only gradually. The personal consumption expenditures price index — the Federal Reserve's preferred gauge — showed disinflationary pressure through the summer, with the headline rate down from its May peak. The trend shows easing, not acceleration.

So the structure of the inflation problem is narrower than the "quadruple whammy" suggests. Tariffs and energy shocks are genuine supply-side pressures. They raise prices without increasing output or wages. That is an important distinction: it means the Federal Reserve faces a problem it cannot solve by raising interest rates alone. Higher rates would slow demand and hurt the already-wobbly labour market, but they would not remove tariffs or reopen the Strait of Hormuz. The Fed's chairman, Kevin Warsh, who was sworn in on May 22nd, has staked his reputation on price stability. But supply shocks are not demand problems.

The market seems to understand this. Corporate earnings are growing fast enough to carry valuations even as consumer prices rise. The inflation that matters most to equity valuations is the kind that triggers sustained rate hikes and compresses discount rates. The Fed left rates at 3.50-3.75% in June with a unanimous 12-0 vote. Whether the balance shifts toward tightening is the open question. The consensus, for now, is that the Fed will not embark on a new tightening cycle.

To be sure, the tariff-and-energy combination is not costless. Tariffs reduce economic efficiency by design: they redirect spending toward more expensive domestic alternatives while inviting retaliation. Real purchasing power is being squeezed. The personal savings rate has fallen toward a four-year low, suggesting households are absorbing the hit from higher prices. The burden falls disproportionately on lower-income families, who spend a larger share of their income on goods that are most likely to be tariffed.

The deeper problem is political. Mr Trump campaigned on lowering costs and "ending inflation". Instead, his tariffs and his war in Iran are making American life more expensive. The tariff policy was designed to extract concessions from trading partners and protect domestic industries. What it has done instead is create a constituency for permanent subsidy, raise input costs for manufacturers and widen the gap between rhetoric and lived experience. The Supreme Court's ruling showed that the legal foundations were thin; the administration's pivot to Section 301 and Section 222 authority shows the political incentive to maintain tariff levels is thick.

The "quadruple whammy" narrative is wrong about the diagnosis, even if it is right to be uneasy. The danger is not a wage-price spiral. It is a supply-side squeeze on an economy whose labour market is already softening, whose central bank cannot fix the problem with interest rates, and whose politics make it difficult to reverse the policies that caused it. Stocks may keep climbing on earnings. But the economy underneath them is being reshaped by tariffs and geopolitical risk into something more expensive and less efficient.

That bargain is not sustainable. Consumers pay first. The question is how long they can keep doing so before something gives.
