Bond Vigilantes and Inflation: Do Domestic Bond Markets Promote Price Stability?

This paper explores the relationship between inflation and the existence of a local, nominal, publicly traded, longmaturity, domestic currency bond market. Domestic bond markets have an unclear effect on inflation; they present issuing governments with the opportunity to inflate away their debt obligations, but they also expose bondholders to capital losses through inflation, creating a potential anti-inflationary force. We ask whether the latter effect is apparent empirically. We use a panel of data, examining inflation before and after the introduction of a domestic bond market. Inflationtargeting countries with a bond market experience inflation at least 3 to 4 percentage points lower than those without one. This effect is economically and statistically significant; it is also insensitive to a variety of estimation strategies. In particular, we use a wide variety of political and fiscal instrumental variables to account for the potential endogeneity of domestic bond issuance. Moreover, we do not find a similar effect for indexed or foreign currency bonds.
