Inflation and Floating-Rate Loans: Evidence from the Euro-Area

Abstract

We provide novel evidence on the supply-side transmission of monetary policy through a floating-rate channel. After a rate hike, firms with floating-rate loans may keep prices elevated to offset higher borrowing costs, thereby reducing the effectiveness of monetary policy. Using monthly data on product-level prices, industry-level inflation rates and the euro-area credit register from 2021 to 2023, we find that the short-run impact of monetary tightening on inflation is 50% smaller when firms rely on floating rate loans. This effect is stronger in concentrated, high mark-up markets, where firms can more easily pass on higher prices to their customers, as well as in markets with highly leveraged or illiquid firms. Since firms with floating-rate loans face an increase in their financial burden, their loan terms are more frequently renegotiated, often resulting in reduced spreads and a shift from floating to fixed rates. Overall, if firms across the euro area had a lower reliance on floating-rate loans, inflation would have been 0.8 percentage points lower in 2022-2023.
