Yes, it is clearly the Fed's self-interest not to raise interest rates because of the associated increase to the debt servicing cost of its liabilities to commercial banks (in the form of bank deposits)...which is why (in spite of their stated inflation target) they are doing their darndest (with the US Treasury's help) to understate inflation and not raise interest rates...but for how long can this deception reign?

Sooner rather than later, inflation will rear its ugly head (real rates of inflation are already growing) and the Fed will have little choice but to raise interest rates (i.e. debt servicing costs) meaning that their balance sheet will begin to look very sick ($trillions of toxic assets costing a pretty penny to own).

Debt doesn't disappear - there's a cost borne by someone, and increasingly that is going to be future generations of US taxpayers. GDP growth is nowhere near high enough to service future payments on that debt. A slippery slope for debt laden governments and global financial markets...and thereby (back to thread) good for gold.
