Since 1975, the nominal annual premium on the 30 year Treasury bill has averaged 2.2 in other words, over its lifespan, the 30 year nominal T bill yields are 2.2 percentage points more than the expected average of future short term nominal T bill rates.

The only slight difference is that the Fed is buying seven year Treasury notes rather than three month Treasury bills.

Whenever a crisis erupts, the value of US Treasury bonds gets a boost.

The long term nominal and real Treasury rates continue to be absurdly low, so much so that I rub my eyes whenever I see them. And the market inflation forecast the spread between Treasury Inflation Protected Securities and normal Treasuries remains extremely tame.

A ten year Treasury has a nominal interest rate of less than 2 .

Curtailing purchases of US Treasuries is a perfectly logical outgrowth of this process.

For example, a German investor would consider United States bonds to have more currency risk than German bonds (since the dollar may go down relative to the euro) similarly, a United States investor would consider German bonds to have more currency risk than United States bonds (since the euro may go down relative to the dollar).

Some critics object that a collapse of US Treasuries and a dollar crash are not the same.

The current 30 year T bill yields 3.2 annually, which means that, unless the marginal bond buyer today is unusually averse to holding 30 year Treasuries, she anticipates that short term nominal T bill rates will average 1 per year over the next generation.

Chinese leaders clearly realize that their hoard of T Bills is a problem.

Frustrated investors would then dump their US Treasury securities. Bond yields would shoot up.

Not surprisingly, the major investors in US Treasuries, China and Japan, have expressed alarm.

The very low interest rate on long term United States Treasury bonds is a clear example of the current mispricing of financial assets.

The market price of Treasuries eventually will fall to levels dictated by US economic fundamentals.

First, there are limits to how many trillions of dollars China can, and should, put into US Treasury bills.

The yield on ten year Treasuries is now 1.6 , down from 3.4 at the start of 2011.

The result is that China and other East Asian countries own a large and growing stock of US Treasury bills.

Yes, there is a minus sign in front of that if you buy the five year TIPS, each year over the next five years the US Treasury will pay you in interest the past year s consumer inflation rate minus 1.02 .

The Commission (or Treasury) would then decide how many additional Eurobonds to issue and on whose behalf.

Indeed, the rate on inflation adjusted US Treasury bills (so called TIPS ) is now negative up to 15 years.

In the short run, then, a US Treasury market crisis might lead to some knee jerk appreciation of the dollar.

That expected inflation rate is consistent with the difference in interest rates between ordinary US government bonds and Treasury Inflation Protected Securities.

Older people, who were prudent and held their money in government bonds, will see lower returns further curtailing their consumption.

It naturally raises the question why aren t people moving their money from TIPS (and US Treasury bonds and other safe assets) to stocks (and other relatively risky assets)?

Moreover, the US government provides a very good inflation hedge in the form of Treasury Inflation Protected Securities (TIPS).

Indeed, US Treasuries were among the few assets that did not decline during the global financial crisis in 2008 2009.

The days of its open ended buying of Treasuries will soon come to an end.

In 1985, the interest rate on ten year Treasury bonds was 10 , even though inflation had declined to less than 4 .

Otherwise, Treasury bond yields would be far higher, thwarting monetary expansion by the Fed.

So we like to see profits, and environmental benefits, when we invest.

China does not buy Treasuries out of benevolence, or because it looks to America as a shining example of wealth and prosperity.

If you invest 10,000 in the five year TIPS, you can confidently expect a five year loss of 510.

European governments debt may all be denominated in euro, but German and Italian debt are hardly the same thing, so the government euro bond market lacks the depth and liquidity of the US Treasury Bill market.

But there is no guarantee that demand for these Treasury notes among foreign investors including foreign governments will be sufficient.

It would finance the purchases by issuing European Treasury bills joint and several obligations of the member countries and pass on the benefit of cheap financing to the countries concerned.

It may be too late to do anything about China s existing stock of US treasuries without causing a serious political and financial backlash. But China should at least stop increasing its holdings.

But these limited kinds of choices for example, a T bill fund with 90 in T bills and 10 in an indexed stock fund could easily be introduced into the public social security system.

The US can finance these deficits in the short term in fact, interest rates on US Treasuries have recently fallen to record low levels.

Financial firms sell assets, like Treasury bonds or real estate securities, for cash, and promise to buy those assets back (i.e., to repurchase them or, for short, to do a repo ), typically the following day.

He parks this 10 million in Treasury bills, too, and sells another 10 million options. This nets him another 1 million, which he uses to cover expenses.

Historically, the real interest rate on ten year Treasuries has been above 2 thus, today s rate is about two percentage points below its historical average.

With Treasury yields spiking and economic activity collapsing, the Fed would want to cut interest rates and flood the markets with liquidity.

China may point to the mountain of US Treasury bonds that it has bought up, thereby helping to sustain America s budget deficit.

Since WWII, the US unemployment rate has averaged 8 when the short term nominal T bill rate is 2 or lower.

But, in July 2011, the ten year US Treasury bond rate crashed to 2 , and it was below 1.5 at the start of June.
