Why the Fed's Rate Hikes Are the Wrong Medicine for Corporate-Driven Inflation

The traditional medicine for inflation is a bitter pill. When prices rise too quickly, central banks like the Federal Reserve reach for their primary weapon: interest rate hikes. By making it more expensive to borrow money, the Fed intentionally slows down economic growth. Businesses invest less, hiring cools, and consumer demand drops. In the orthodox macroeconomic playbook, this induced slowdown breaks the "wage-price spiral," forcing prices back down to earth. It is a blunt instrument that relies on inflicting economic pain—specifically on workers—to stabilize the currency.[7]

But what if the diagnosis is wrong? Over the past few years, a growing chorus of heterodox economists and policy institutes has argued that the inflation of the 2020s was not driven by an overheated labor market or excessive wage demands. Instead, they point to a phenomenon known as "seller's inflation"—a structural shift where corporations used overlapping global emergencies as a shield to aggressively expand their profit margins.[1][3]

If this alternative diagnosis is correct, it exposes a fundamental mismatch in global economic policy. Treating corporate-driven inflation with interest rate hikes is akin to treating a bacterial infection with painkillers. It may mask some of the symptoms by crushing consumer demand, but it leaves the underlying pathology—corporate pricing power and market consolidation—completely untouched.[7]

The data supporting the "greedflation" narrative is compelling. According to analysis by the Economic Policy Institute (EPI), corporate profits accounted for well over 40% of the rise in prices during the initial post-pandemic recovery. To put that in perspective, over the four decades prior to the pandemic, corporate profits historically contributed just 11.5% to price growth.[1]

This was not merely a passive result of market forces. A report by the Groundwork Collaborative, which analyzed hundreds of corporate earnings calls, found executives openly boasting to shareholders about their ability to maintain high prices and widen profit margins even as their supply-chain costs plummeted. The report concluded that corporate profits were still driving more than half of inflation as late as mid-2023.[4]

The theoretical framework for this phenomenon was pioneered by Isabella Weber, an economist at the University of Massachusetts Amherst. Weber argues that the global economy experienced a series of unprecedented, overlapping shocks—from pandemic lockdowns to the war in Ukraine—that disrupted essential sectors like energy, shipping, and raw materials.[3]

In a highly consolidated economy, Weber explains, these sector-wide cost shocks act as a "coordinating mechanism." When every firm in an industry faces the same supply-chain crisis, it sends a clear signal that it is safe to hike prices. Because companies know their competitors are doing the same, they can raise prices without the traditional fear of losing market share.[3]

This dynamic fundamentally breaks the traditional macroeconomic model. If inflation is being driven by the pricing power of oligopolies rather than a tight labor market, the Federal Reserve's interest rate hikes are targeting the wrong culprit.[1][7]

Rate hikes work by suppressing wages and increasing unemployment. But suppressing wages does nothing to dismantle the pricing power of a consolidated shipping cartel or a dominant food conglomerate. In fact, it punishes the very workers who are already losing purchasing power to inflated grocery and energy bills.[1][5]

Furthermore, aggressive monetary tightening can actually entrench corporate power. Higher interest rates make capital prohibitively expensive for smaller startups and challengers, while cash-rich mega-corporations can self-fund their operations. By bankrupting smaller competitors, rate hikes can inadvertently increase the market concentration that allows for price gouging in the first place.[7]

Unsurprisingly, the Federal Reserve and mainstream economists have pushed back heavily against the seller's inflation narrative. They argue that corporations have always been greedy; what changed in the 2020s was a massive injection of government stimulus that gave consumers the excess savings required to absorb higher prices.[2][6]

A 2023 paper published by the Federal Reserve offered a direct rebuttal to the EPI data. The Fed researchers argued that the spike in aggregate corporate profit margins was largely a mirage created by unprecedented government subsidies, such as the Paycheck Protection Program, and the temporary reduction in net interest expenses due to rock-bottom rates.[2]

According to the Fed's analysis, once you strip out these direct fiscal interventions, corporate profit margins during the pandemic recovery look much closer to their historical averages. From this orthodox perspective, inflation was a classic case of too much money chasing too few goods, and rate hikes were the necessary, if painful, solution.[2]

Yet, the persistence of high prices even as supply chains normalized and stimulus checks dried up has kept the heterodox critique alive. If the seller's inflation theory holds true, the policy prescription for future economic shocks must shift dramatically away from central banks.[3][5]

Instead of relying on the Federal Reserve to induce a recession, proponents of the greedflation theory advocate for a fundamentally different toolkit. This includes targeted price controls on essential goods, aggressive antitrust enforcement to break up sectoral monopolies, and the implementation of temporary excess profits taxes.[1][3]

An excess profits tax, for instance, would directly disincentivize price gouging. If a corporation knows that any windfall margins generated by a global crisis will be taxed away, the incentive to aggressively hike prices evaporates. Similarly, robust antitrust action would ensure that markets remain competitive enough that a single supply shock cannot be used as a coordinating mechanism for industry-wide price hikes.[1]

Ultimately, the debate over corporate-driven inflation is not just a technical dispute over macroeconomic modeling. It is a profound political question about who should bear the cost of economic stabilization.[5][7]

For decades, the consensus has been that workers must absorb the pain of inflation fighting through higher unemployment and suppressed wages. But as the mechanics of seller's inflation become clearer, policymakers are being forced to ask whether it is time to target the boardrooms that set the prices, rather than the workers who pay them.[4][7]
