It is now widely accepted that deglobalization—the retrenchment of global trade, unwinding of capital flows, new barriers to migration, and declining influence of multilateral institutions—is well underway. But policy makers have yet to acknowledge its contribution to global inflation. To rein in surging price growth, the Federal Reserve and other central banks must adjust to the challenges of a rapidly deglobalizing world.

Globalization acted as a deflationary force by reducing labor and production costs. Likewise, the main features of deglobalization—higher tariffs and other trade barriers, together with a shift from global to regional trade flows—are known drivers of inflation. It is no surprise, then, that core goods inflation in the United States has increased sharply, from less than 2% at the start of 2021 to 6% in mid-2022.

I recently argued that U.S. inflation is headed for a decline because the American economy is uniquely equipped to mitigate the impact of surging prices. But deglobalization will likely contribute to inflationary pressures by increasing companies’ operating costs, thereby keeping U.S. inflation higher than the 1%-2% range recorded over most of the past decade and hovering near the Fed’s 2% target rate.

For decades, U.S. corporations have benefited tremendously from globalization’s deflationary effects. Now, however, ongoing supply-chain constraints related to China’s strict zero-Covid policy and Russia’s war in Ukraine are expected to continue to raise the prices of food, fuel and manufactured goods over the short and medium term.

More broadly, heightened geopolitical tensions threaten to make higher input costs a fixture of a deglobalizing world. While the cross-border movement of goods, capital and people characterized the globalized economy of the past three decades, the growing Sino-American rivalry could be a harbinger of an era marked by a widening ideological divide and a balkanized global economy. Barriers to migration would make it harder for U.S. companies to attract top global talent and drive up labor costs.

As interest rates rise and supply chains remain vulnerable, U.S. companies are favoring resilience over low production costs, leading to massive capital repatriation. According to the Yale School of Management’s tracker, more than 1,000 companies—many of them American—have voluntarily curtailed their Russian operations beyond what international sanctions require. In a deglobalizing economy, more investment capital would flow back to the U.S., leading to a higher volume of dollars chasing U.S. assets and putting more upward pressure on prices.

Finally, the notable absence of monetary-policy coordination—particularly among developed economies—may exacerbate global price increases. Unlike the coordinated monetary response to the 2008 global financial crisis, policy makers in the world’s major economies seem to believe that every country must fend for itself in the fight against today’s inflationary surge. While G7 leaders have pledged to monitor global inflation, they have not announced measures to combat soaring prices in a coordinated manner. On the contrary, the one recent coordinated policy action G7 countries undertook—sanctions against Russia—has arguably worsened inflationary pressures, by increasing supply-chain interruptions and spurring a spike in fuel prices.

The absence of global cooperation hurts many of the world’s most vulnerable countries the most. When major central banks hike interest rates, they export inflation to smaller countries. Aggressive monetary tightening in the U.S. has already led the dollar to rise against the pound, breach parity with the euro, and reach a 20-year high against the yen, propelling higher import-led inflation in countries whose currencies have weakened.

Tackling inflation in the U.S. and globally requires a coordinated multilateral response. At a minimum, such a response would benefit the U.S. by reducing its long-term exposure to rising import costs. Conversely, diplomatic fragmentation—a defining characteristic of our current age of deglobalization—increases the likelihood of tit-for-tat measures, which have led to the erection of multiple trade barriers in recent years, most notably between the U.S. and China and between the United Kingdom and Europe.

Taken together, these trends herald a global environment that will continue to fuel higher U.S. inflation, even if America is less vulnerable than other advanced economies. The Fed’s current efforts to stamp out inflation by hiking interest rates and shrinking its balance sheet will reduce demand and thus help curb price growth. But policy makers must also devise measures that mitigate the impact of today’s deglobalizing world.
