NEW YORK – The Greek debt crisis has prompted questions about whether the euro can survive without a nearly unimaginable centralization of fiscal policy. There is a simpler way. Irresponsible borrowing by governments in international credit markets requires irresponsible lending. Bank regulators should just say no to such lending by institutions that are already under their purview.
Lending to foreign governments is in many ways inherently riskier than unsecured private debt or junk bonds. Private borrowers often have to offer collateral, such as their houses. The collateral limits the lenders’ downside risk, and the fear of losing the pledged assets encourages borrowers to act prudently.
