The Federal Reserve’s usual playbook for taming inflation may not work this time around, according to a former top central banker. In a blunt Substack post last week, Patrick Harker, who ran the Philadelphia Fed from 2015 to 2022, argued that calling events like Russia’s 2022 cutoff of natural gas to Europe a “supply shock” is a dangerous oversimplification. “A shock is a surprise. A shock is the kind of thing you absorb, smooth out, and move past,” Harker wrote. “What Russia did to Europe’s gas supply was none of those things. It was a deliberate act, executed for political reasons—and that changes everything.”

Harker’s argument cuts to the heart of the Fed’s dilemma as it tries to bring inflation down without crushing the economy. The central bank has spent the last two years raising interest rates to cool demand, but inflation in early 2024 is still running above its 2% target. The problem, Harker says, is that the spike in energy prices after Russia’s invasion wasn’t caused by market forces or supply chain snarls—it was the result of a government weaponizing trade. Traditional monetary policy tools, like higher interest rates, don’t address that kind of disruption.

Why Russia’s gas cutoff broke the old rules

When Russia first invaded Ukraine in February 2022, Europe imported about 40% of its natural gas from Russia. By June of that year, Moscow had slashed those shipments to a trickle, leaving countries like Germany scrambling. Prices for natural gas futures in Europe jumped from around €55 per megawatt hour in January 2022 to over €300 by August. Factories slowed production. Governments spent billions subsidizing households and businesses. The inflation that followed wasn’t just a side effect of war—it was a direct result of a calculated economic attack.

Harker isn’t the first to call out Russia’s tactics. In 2022, the European Union labeled the gas cutoff a form of “economic coercion,” and the U.S. Treasury later sanctioned Russian gas giant Gazprom for its role in weaponizing energy. What’s new is Harker’s push to reframe these events not as random disruptions but as deliberate tools of statecraft—and to argue that central banks need to adjust their strategies accordingly.

The Fed’s blind spot

Monetary policy works best when inflation stems from too much demand or broken supply chains. Raise interest rates, and consumers spend less. Fix the supply chain, and prices stabilize. But when a foreign government intentionally tightens supply for political gain, higher interest rates can’t fix the problem—they just make the recession worse. Harker’s point is that the Fed needs to recognize this distinction if it wants to avoid overcorrecting, as it did in 2022 when it raised rates too aggressively and tipped the economy into a sharp slowdown.

The Fed’s own economic models aren’t built to handle this kind of shock. Standard models assume supply disruptions are temporary and random, not sustained and intentional. That’s why Harker’s critique resonates with economists who’ve been warning that the Fed’s tools are ill-equipped for today’s geopolitical risks. As Larry Summers, former Treasury secretary, put it in a recent interview, “The Fed is still using a 1990s playbook in a 2020s world where supply chains can be turned off with a switch.”

What happens next?

Harker doesn’t offer a clear solution, but he implies the Fed needs to think differently about inflation. One approach could be for the central bank to factor geopolitical risks into its rate decisions—something it’s never done before. Another is for governments to diversify energy supplies faster, reducing their vulnerability to political manipulation. Either way, the message is clear: if supply disruptions are strategic, not accidental, the response can’t just be higher interest rates. The Fed’s next move will show whether it’s paying attention.

🇧🇷 Resumo em Português

A crise energética na Europa não foi um acidente, mas uma jogada política russa. Segundo o ex-diretor do Federal Reserve (Fed) Patrick Harker, o corte no fornecimento de gás por Moscou não foi um choque aleatório, mas uma estratégia deliberada para pressionar o continente — um fenômeno que ele classifica como “coerção de oferta”. O episódio, que levou a preços recordes de energia em 2022, expôs como dependências comerciais podem se tornar armas geopolíticas, redefinindo a relação entre economia e segurança global.

No Brasil, o alerta ressoa especialmente após os recentes embates envolvendo acordos comerciais e sanções internacionais. O país, embora autossuficiente em energia, tem visto seus setores industriais e de transportes sofrerem com a volatilidade dos preços globais, como no caso do diesel e dos fertilizantes. A lição europeia reforça a necessidade de diversificar parceiros e investir em fontes alternativas, como o pré-sal e a transição energética, para evitar que crises externas afetem a estabilidade econômica nacional. Além disso, o episódio reforça a importância de acordos regionais que garantam segurança energética, como o Mercosul, como escudo contra pressões geopolíticas.

A discussão sobre “coerção de oferta” deve ganhar força nos próximos anos, especialmente com a crescente rivalidade entre potências como China, Rússia e Estados Unidos, que já mostram sinais de usar recursos naturais como moeda de barganha.

🇪🇸 Resumen en Español

Las crisis energéticas en Europa no fueron fruto del azar, sino un movimiento calculado por Moscú. Así lo advierte el exfuncionario de la Reserva Federal Patrick Harker, quien redefine lo que tradicionalmente se llamó “shocks de oferta” como “coerción por suministro”, una estrategia deliberada para ejercer presión geopolítica.

Esta nueva perspectiva revela cómo la dependencia energética puede convertirse en un arma política, con consecuencias directas para hogares y empresas. Para el público hispanohablante, especialmente en regiones con fuerte lazos comerciales con Rusia o dependientes de sus exportaciones, este análisis subraya la urgencia de diversificar fuentes de energía y reforzar la seguridad en las cadenas de suministro. Además, plantea un debate sobre hasta qué punto los países deben blindarse ante prácticas que trascienden lo económico para adentrarse en lo estratégico.
