As Dr. Krugman notes, the Fed’s flow of funds data leaves little doubt that — at least during the first quarter — the rise in public borrowing was fully offset by a fall in private borrowing. An updated version of the chart I posted last week comparing government and private borrowing can be found on the website of the Council’s Center for Geoeconomic Studies.
Total US borrowing by the non-financial sector (annualized) was under $1.4 trillion in the first quarter — down from $1.9 trillion in calendar 2008 and $2.5 trillion in calendar 2007. In the first quarter, Americans borrowed less, at an annualized rate than they did in 2003.
The federal government borrowed over $1.4 trillion – -and if throw in state and local governments, total public borrowing topped $1.55 trillion. That isn’t a small sum. But households were borrowing (they actually paid down their outstanding debt in the first quarter). And modest borrowing by corporations was offset by a fall in borrowing by noncorporate business. Firms and households combined to reduce their borrowing by a bit less than $200 billion ($184.1 billion). To put that in perspective, households and firms borrowed over $2 trillion in 2006. That is an epic fall.
Borrowing less in aggregate translated into borrowing less from the rest of the world. If the flow of funds is right, the current account deficit in the first quarter in the first quarter was under $300 billion dollars ($293 billion according to table F107). $300 billion is closer to 2% of US GDP than 3% of US GDP. The result, obviously, is less need to borrow from the rest of the world — or to sell equity to foreign investors — to finance the United States import bill.
Who bought all the Treasuries the US government has issued in the last four quarters of data (q2 2008 to q1 2009)? Foreign demand for Treasuries — as we have discussed extensively — hasn’t disappeared, unlike foreign demand for other kinds of US debt. But foreign demand hasn’t increased at the same pace as the Treasury’s need to place debt. The gap was filled largely by a rise in demand for Treasuries from US households.
