Resilience, inflation and debt: Three calls for the global economy

The global economy has shown remarkable resilience to various unprecedented shocks, but inflation never truly goes away. And might 2026 be the year radical measures need to be taken on debt sustainability?

Our risky call: Shorter inflation cycles

Since the pandemic, inflation is back. Its surge triggered aggressive monetary policy tightening, which was quickly reversed as inflation then slowed. Even though inflation has remained slightly too high to give central banks full comfort, it does seem to have become less of a concern. After the long inflation cycle, our risky call is that many economies could see shorter inflation cycles this year and beyond as both inflationary and disinflationary forces are strengthening.

In the short run, cyclical disinflation on the back of weaker labour markets and slowing wage growth could still prevail. However, the delayed impact of tariffs and fiscal stimulus could still easily reignite things later in the year. Consequently, 2026 could mark the beginning of a stop-and-go inflation pattern, with shorter but more frequent cycles.

Our bold call: The return of QE

Most governments of industrialised countries are currently facing the same dilemma: how to pay for things they can’t afford. This holds true for the US, where tariff revenues have risen but remain far too small to fund any additional stimulus – stimulus that could be needed to support the economy or make living costs more affordable. But in Europe, too, where investment needs are high, demographic change is adding to fiscal pressures, and there seems to be little appetite for structural reforms or austerity.

In this world, government debt will continue to increase. While our base case foresees no significant implications from higher debt in 2026, a bold call is clearly the return of asset purchases. As the industrial world increasingly enters an era of fiscal dominance and central banks would rather avoid returning to the zero-interest rate bound, a return to asset purchases, voluntarily or gently forced by governments, could easily be on central banks’ policy menu again.
