Foreign-currency bonds: currency choice and the role of uncovered and covered interest parity

Using count-data techniques, this article studies the determinants of currency choice in the issuance of foreign-currency-denominated bonds. In particular, we investigate whether bond issuers choose their issuance currency in order to exploit the borrowing-cost savings associated with deviations from uncovered and covered interest parity. Our findings show that the choice of issuance currency is sensitive to deviations from uncovered interest parity but insensitive, in general, to deviations from covered interest parity. Furthermore, the influence of deviations from uncovered interest parity is stronger for financial issuers than for nonfinancial issuers. In as much as the issuance of foreign-currency-denominated bonds affects the relative international standing of world currencies, one implication of these findings is that monetary policy, through its influence on nominal interest rates, has a greater impact on the internationalization of currencies than has been previously accounted for.
