In the four months since the unthinkable U.S. downgrade from AAA to AA+, Bloomberg points out, "Dollar-denominated financial assets are doing nothing but appreciating."

Indeed, in that time government bonds have returned 4.4%, the dollar gained 8.6% relative to a basket of currencies, and the S&P 500 index increased 1.7%. Long-term treasuries are the best performing government bonds in the world this year, returning 30%, according to Bloomberg/EFFAS indexes.

"The cost for the nation to borrow has fallen to record lows since S&P said the U.S. was no longer risk-free, with the average monthly yield in November on 10-year notes below 2 percent for the first time since 1950."

Victory against the odds
Sure, Standard and Poor's had some good points when it downgraded the United States, chief of which was Congress' incompetence in the areas of compromise and its inability to lead the country toward a future of fiscal utopia.

What's more, government borrowing recently surpassed $15 trillion for the first time and the budget deficit exceeds $1 trillion for a third year.

But Standard & Poor's misjudged the U.S.' ability to print as much money as it needs to pay its debts. With this power, the United States can pay investors back with ease compared to the EU nations.

The prices of U.S. Treasuries were not much affected either. Michael Cirami, a money manager at Boston-based Eaton Vance Corp. places them "among the safest assets that one can hold" noting a downgrade does not change the liquidity of treasuries.

Apparently foreign investors aren't phased by the downgrade either. According to Bloomberg, foreigners increased holdings of Treasuries by $17.2 billion in August, September and October to $4.66 trillion. Non-U.S. buyers own about 48% of U.S. marketable debt, up from 34% when the nation had a budget surplus in December 2000.
