The development of financial markets and banking activity coupled with the strengthening of banking regulations has largely affected the new structure of external financing of emerging countries. Indeed, the financial markets influence the behavior of international banks in a context of regulatory strengthening which implies a contraction of the bank flows volume and a decrease in the maturity of these flows. The empirical results, for 37 emerging countries, confirm that financial markets have influenced differently the volume and the term structure of bank flows from developed to emerging countries according to the regulatory context.
