US Caught China Buying More Treasuries

Reuters reports:

When the Treasury Department revamped its rules for participating in government bond auctions two years ago, officials said they were simply modernizing outdated procedures.

The real reason for the change, a Reuters investigation has found, was more serious: The Treasury had concluded that China was buying much more in U.S. government debt than was being disclosed, potentially in violation of auction rules, and it wanted to bring those purchases into the open - all without ruffling feathers in Beijing.

Treasury officials then worked to keep the reason for the auction-rule change quiet, with the acting assistant Treasury secretary for financial markets instructing subordinates to not mention any specific creditor's role in the matter, according to an email seen by Reuters. Inquiries made at the time by the main trade organization for Treasury dealers elicited the explanation that the change was a "technical modernization," according to a document seen by Reuters. There was no mention of China.

The incident calls into question just how clear a handle the Treasury has had on who is buying U.S. debt. Chinese entities hold at least $1.115 trillion in U.S. government debt, and are thought to account for roughly 26 percent of the paper issued by Washington, according to U.S. government data released on June 15.

China's vast Treasury holdings are both a lifeline and a vulnerability for Washington - if the Chinese sold their Treasuries all at once, it could undermine U.S. markets and the economy by driving interest rates higher very quickly. Scenarios of this sort have been discussed in Washington defense-policy circles for at least a year now. Not knowing the full extent of these holdings would make it even more difficult to assess China's political leverage over U.S. finances.
