The government stands more to lose by a rate hike than any other individual entity. Ten year notes are traded in an open market, and sold at auction - Treasury can't just set a price and expect people to pay. If the prevailing ten year rate reverted back to the historical average of 4.9%, 30% of the Federal budget would have to be dedicated to just servicing the interest on the debt.

For Uncle Sam, low rates are about survival. We're in deep caca.
