But China could reduce or halt future purchases. A less ravenous appetite for Treasurys is already evident: a
New York Times article in January was titled: "China Losing Taste for Debt From U.S." One reason for fewer purchases would be diversification. Another would be to divert money toward its own 4 trillion yuan ($586 billion) stimulus package.
Reduced demand for Treasurys would drive up U.S. interest rates, probably pushing down home prices even more than they've already fallen, and also could
start a run on the dollar.
This is why Secretary of State Hillary Clinton
pleaded with the Chinese government last month to keep the loans flowing to Washington, D.C. ("So by continuing to support American Treasury instruments, the Chinese are recognizing our interconnection.")
This is also why, at least in part, U.S. taxpayer dollars were used to bail out Fannie Mae and Freddie Mac last year. A
Business Week article says that foreign bankers were worried, especially China, which owned around $376 billion of Fannie and Freddie debt. "Treasury saw foreign governments getting the willies," a Senate aide told the magazine.
to other investors (foreign and domestic), who would presumably require higher
interest rates than those prevailing today to be enticed to buy them. One analyst
estimates that a Chinese move away from long-term U.S. securities could raise
interest rates by as much as 50 basis points.26 Higher interest rates would cause a
decline in investment spending and other interest-sensitive spending. All else equal,
the reduction in Chinese Treasury holdings would cause the overall foreign demand
for U.S. assets to fall, and this would cause the dollar to depreciate. If the value of
the dollar depreciated, the trade deficit would decline, as the price of U.S. exports fell
abroad and the price of imports rose in the United States.27 The magnitude of these
effects would depend on how many U.S. securities China sold; modest reductions
would have negligible effects on the economy given the vastness of U.S. financial
markets. For example, Japan gradually reduced its Treasury holdings from $699.4
billion to $582.2 billion from August 2004 to September 2007, a decline of $117.2
billion. This shift appears to have had little noticeable impact on the U.S. economy. - ignt rn on 2010-01-21
suddenly reduce their liquid U.S. financial assets significantly. The effect could be
compounded if this action triggered a more general financial reaction (or panic), in
which all foreigners responded by reducing their holdings of U.S. assets. The initial
effect could be a sudden and large depreciation in the value of the dollar, as the
supply of dollars on the foreign exchange market increased, and a sudden and large
increase in U.S. interest rates, as an important funding source for investment and the
budget deficit was withdrawn from the financial markets. The dollar depreciation
would not cause a recession since it would ultimately lead to a trade surplus (or
smaller deficit), which expands aggregate demand.28 (Empirical evidence suggests
that the full effects of a change in the exchange rate on traded goods takes time, so
the dollar may have to “overshoot” its eventual depreciation level in order to achieve
a significant adjustment in trade flows in the short run.)29 However, a sudden
increase in interest rates could swamp the trade effects and cause a recession. Large
increases in interest rates could cause problems for the U.S. economy, as these
increases reduce the market value of debt securities, cause prices on the stock market
to fall, undermine efficient financial intermediation, and jeopardize the solvency of
various debtors and creditors. Resources may not be able to shift quickly enough
from interest-sensitive sectors to export sectors to make this transition fluid. The
Federal Reserve could mitigate the interest rate spike by reducing short-term interest
rates, although this reduction would influence long-term rates only indirectly, and
could worsen the dollar depreciation and increase inflation. - ignt rn on 2010-01-21
