How is the US current account deficit financed today?
Core argument: The US current account deficit is the largest of all and is financed mainly through portfolio debt flows.
The US current account deficit, the largest deficit of all, is mainly financed via portfolio debt flows. Geographically, the financing of the US current account deficit has become increasingly mediated by financial centers in recent years. This contrasts with the pre-GFC period, when the US current account deficit was financed largely through reserve accumulation from surplus countries. Balance-of-payments data show a declining role for China.
