Does inflation reduce the global debt burden?
Core argument: IIF data show the global debt-to-output ratio reached a post-Covid peak of 337% in early 2021 before falling by 27 percentage points by the end of 2023, with inflation identified as the force that eroded it.
The IIF shows that between 2018 and June 2026, the rise in the ratio of global debt to output was less than 10 percentage points. The story is striking: the ratio reached a post-Covid peak of 337% in early 2021, before falling by 27 percentage points by the end of 2023. What was this magical “debt-buster”? Good old-fashioned (and supposedly “unexpected”) inflation. This is — to put it mildly — not the first time inflation has wiped out debt. It was, to take one of countless examples, an important part of the UK’s elimination of its post-second-world-war debt. For countries able to print the money in which their debt is denominated, that is often what happens.
