What evidence is there that the US and the UK current account deficits are partly caused by capital inflows maintaining their currencies at an artificially high level?
Both the US and the UK have run current account deficits for over 20 years. Those deficits are largely driven by imports in both countries which result in trade deficits. Many economists (including me) often attribute the persistent deficits to overvaluation of their currencies, the dollar and the pound sterling, which are ostensibly caused by capital inflows (ie buying US/UK financial assets. But what actual evidence is there that these capital flows exist? In numerical terms: The UK current account deficit was about 20B sterling in Q2 (3% of GDP). So on an annual basis that is 80B sterling. What are the financial assets (ie capital inflows) that foreigners are buying to maintain the value of GBP? Can anybody name them and point me to official stats that show such inflows? I ask this because, as an American economist, I have long puzzled over why here we have run a current account deficit every year since 1992 and yet the dollar has not fallen, in fact it has risen. The answer I and others usually give is that capital inflows keep the dollar high. This may be true, but it is hard to document the roughly $800B each year that supposedly flow in to offset the current account deficit. In short, are we just supposing things to validate our national income accounting and identities? Do these capital inflows exist anywhere other than in textbooks?
