We present novel empirical evidence on lending practices across all euro area countries, using AnaCredit data covering nearly seven million new loans issued to non-financial corporations in 2022-23. We document substantial variation in (a) the prevalence of fixed versus floating-rate loans, (b) rate fixation periods, and (c) reference rates. This variation results in lending rates being exposed to different segments of the risk-free rate yield curve which, in turn, influences their sensitivity to monetary policy changes. We show that loans priced using shorter-term relevant risk-free rates experience more pronounced monetary pass-through. Importantly, this effect is not purely mechanical, as part of the effect is offset by adjustments in the premium, revealing previously less explored heterogeneity in the pass-through to lending rates.
