ECB Research Bulletin examining whether high public debt undermines central banks' ability to control inflation. It concludes that they retain control, but higher debt raises the natural rate of interest, so they should raise rates in response to debt increases rather than wait for the resulting inflation.
Key points
- With non-Ricardian households, higher public debt creates inflationary pressure
- The debt limit beyond which control would be lost is estimated at 5.4 times annual GDP
- In the US, one point more of debt to GDP raises long-term rates by about 3 basis points

Plain-language version
An ECB study (the ECB is the euro area's central bank) asks whether high government debt weakens its power to control inflation. The answer is no, but more debt raises the natural interest rate, the level that neither slows nor speeds up the economy, so rates should rise early rather than waiting for prices to climb. Put simply, more indebted governments can mean pricier loans and mortgages.
