Abstract: Do exchange rate regimes affect the conditions under which developed countries borrow? This paper argues that they do, but their impact on yields depends on the prevailing macroeconomic context. When investors regard inflation as the most relevant risk to bond holdings, monetary union has a distinct advantage over floating and fixed exchange rates because of its credible in-built mechanism to control inflation. However, once default is seen as the most relevant risk, exchange rate rigidity becomes a liability due to its constraining effect on governments' ability to respond to adverse shocks. We test our argument with a moving window panel analysis for twenty-three OECD countries from 1980 to 2017. We find that before the late 2000s, inflation was penalized under floating and (to a lesser extent) fixed exchange rate regimes, but not in countries in monetary union. Since the 2010s, inflation carries no penalty under any exchange rate regime. Variables linked to default risk (debt and entitlement spending) did not affect yields under any exchange rate arrangements until the mid-2000s. Afterwards, countries in monetary union (and to a lesser extent in fixed exchange rate regimes) were significantly penalized for public debt and entitlement spending, whereas countries with floating regimes were not. Our results speak to the literatures on governments' institutional commitments and "room to move.
