The goods news: the US trade deficit has shrunk. On a rolling 12m basis the trade deficit is down to around $500 billion, and the data from the last few months suggests that it should fall even further.
The bad news: the US trade deficit hasn’t shrunk by as much as foreign demand for US long-term assets.
My graph only showed inward portfolio flows. That isn’t the entire balance balance of payments. But inward and outward FDI flows tend to offset each other. And in general Americans have been adding to their foreign portfolio, not reducing their foreign holdings. That means the (remaining) deficit is increasingly financed by short-term flows, which isn’t the most comfortable thing in the world.
All this is pretty clear if you look at the details of the last TIC data release (already covered in depth by Rachel). Over the last three months, private investors reduced their US holdings by over $100 billion (line 31). That total was offset by the repayment of the Fed’s swap lines — but the long-term flow picture isn’t great. Net portfolio inflows over the last 12ms totaled $188 billion (line 19). After adjusting for repayment of ABS, that total falls to zero (lines 20 and 21).
As the following graph shows, net private demand for long-term US assets — that is gross long-term private portfolio inflows net of US portfolio outflows — started to disappear in late 2006, and then took another down leg after the subprime crisis broke in August 2007. And over the last 9 months, official demand for US long-term bonds also disappeared — as reserve growth slowed (until recently) and central banks moved in mass toward short-term treasury bills.
The split between official and private flows in the chart reflects my adjustments to the TIC data – but my adjustments basically just make the TIC data match the US survey data and the revised BEA data on official flows.* My adjustments change the official/ private split, but not the total.
