Fascinating post from Brad Setser detailing China's holdings of USD holdings.
Therein, he describes the dilemma facing China: On the one hand, it wants the US to demonstrate fiscal restraint to protect the value of its USD holdings. But, China also wants a large and vigorous government stimulus package to keep exports humming along.
One dimension that isn't addressed in Brad's post is how (Chinese) politics affect how this dilemma gets resolved.
In my view, the political calculations made by China's leadership should make export growth the preferred option. Exports will bolster employment both directly and through continued attraction of foreign direct investment. This, of course, promotes social stability and keeping the party in power.
While any losses in Chinese USD holdings will likely provoke a firestorm of criticism, this will likely be contained and less likely to up-end the CCP apple cart than the former outcome. Also, losses due to debt monetization may not be as great as when the value of China's holdings are viewed in term of purchasing power parity.
This suggests that the US will, of course, offer the requisite genuflecting to China's concerns. But, from a practical perspective, it isn't in the political interest of China to take any serious action to deter the US from any fiscal actions that threaten the value of its USD holdings.
