“The narrative of overvalued carry trades ending in collapse is one that winds through all of financial history in countries around the globe. Yet the pattern repeats because the allure of ‘reaching for yield’ is so strong. To reach for yield, regardless of price or value, is a form of myopia that not only equates yield with total return, but eventually demands the sudden and magical appearance of a crowd of greater fools in order to exit successfully. The mortgage bubble was fundamentally one enormous carry trade focused on mortgage backed securities. Currency crises around the world generally have a similar origin. At present, the high-yield debt markets and equity markets around the world are no different.”
