It’s no secret that the United States government owes a pretty penny to foreigners. Certainly, what America owes to foreigners pales in comparison to what it owes to Ben Bernanke… but still, $4.45 trillion is no small number, even in these crazy times when terms like “kajillion bajillion” are more appropriate to quantify debt and entitlements.
China is the largest foreign buyer of US Treasuries with around $1.15 trillion in holdings… Japan is the second largest at around $886 billion. Curiously, the trend for China has been down– the Middle Kingdom has been steadily reducing its position since peaking in October 2010.
Japan, on the other hand, has been steadily increasing its Treasury holdings over the same period. Its government does have a long pattern of currency intervention, and there has been much grumbling in Tokyo about the effects of the strong yen on their exports.
Fast forward to this past weekend. Earthquake. Tsunami. Volcano. Nuclear radiation. Japan clearly has other things on its mind right now than to continue financing the ongoing largess in Washington DC.
At a minimum, Japan will likely slow (or eliminate) its US Treasury purchases, instead focusing on dumping money into its own economy. At greater risk, Japan may choose to allow much of its Treasury portfolio to simply mature, requiring the US government to repay tens of billions of dollars of principal (which it doesn’t have).
