The U.S. Treasury announced plans to discontinue use of the 30-year Treasury Bond in October of 2001. At that time, the move made sense for several reasons (some obvious, some not).
During the low interest rate environment, the government should have been focused on arranging as much long term financing as possible.
However, how many investors would have been willing to lock themselves in for 30 years at those rates? It's hard to tell, but it could have been much more than you might think considering the level of global uncertainty.
What also happened during that time? The housing market helped to keep the economy going when things could have been much worse. Many people refinanced their homes, and these interest savings added extra money to the budgets of American families. Furthermore, new home construction provided many good jobs for American workers.
The thing that people may not realize is that low interest rates and easy credit do not go hand in hand. What is the mortgage market? Essentially it is a 30-year bond. Therefore, the demand for fixed income found its way to the housing market. The government provided the low interest rates, but investors who had no other good alternatives supplied the money.
Therefore, the government was actually able to help stimulate the economy by discontinuing the 30-year Treasury Bond.
Now what has happened?
The Chinese have been pressured to revalue (float) their currency. This means that it no longer makes sense for the Chinese government to buy our treasury securities.
They were able to support our debt even at the lowest of interest rates simply because their currency was pegged to the dollar. Not to mention they had a substantial trade surplus. However, the Chinese will now expose themselves to much more risk if they decide to hold massive dollar reserves. Therefore, the time has come to find an alternative source of financing for our budget deficits.
The "conundrum" is not a problem, but a signal. It signals demand. It signals that investors are not so willing to invest in the mortgage market anymore. It signals that the aging Baby Boom generation is becoming more conservative and is searching for fixed income investments.
The U.S. Treasury is now continuing use of the 30-year Treasury Bond. At this time, the move makes sense for several reasons (some obvious, some not).
