China, being the US’s largest foreign creditor, has much to lose from its unsound fiscal decisions
Yes, the United States dodged another bullet with a last-minute deal on the debt ceiling. But, with 90 days left to bridge the ideological and partisan divide before another crisis erupts, the fuse on America’s debt bomb is getting shorter and shorter. As a dysfunctional US government peers into the abyss, China—America’s largest foreign creditor—has much at stake.
It began so innocently. As recently as 2000, China owned only about $60 billion in US Treasuries, or roughly 2% of the outstanding US debt of $3.3 trillion held by the public. But then both countries upped the ante on America’s fiscal profligacy. US debt exploded to nearly $12 trillion ($16.7 trillion if intra-governmental holdings are included). And China’s share of America’s publicly-held debt overhang increased more than five-fold, to nearly 11% ($1.3 trillion) by July 2013. Along with roughly $700 billion in Chinese holdings of US agency debt (Fannie Mae and Freddie Mac), China’s total $2 trillion exposure to US government and quasi-government securities is massive by any standard.
China’s seemingly open-ended purchases of US government debt are at the heart of a web of codependency that binds the two economies. China does not buy Treasuries out of benevolence, or because it looks to America as a shining example of wealth and prosperity. It certainly is not attracted by the return and seemingly riskless security of US government paper—both of which are much in play in an era of zero interest rates and mounting concerns about default. Nor is sympathy at work; China does not buy Treasuries because it wants to temper the pain of America’s fiscal brinkmanship.
China buys Treasuries because they suit its currency policy and the export-led growth that it has relied on over the past 33 years. As a surplus saver, China has run large current-account surpluses since 1994, accumulating a massive portfolio of foreign-exchange reserves that now stands at almost $3.7 trillion.
China has recycled about 60% of these reserves back into dollar-denominated US government securities, because it wants to limit any appreciation of the
