the basic mechanism of the gold carry trade is as follows afaik:
1. central bank lends physical gold to bullion bank for gold interest rate (historically 1-2%)
2. bullion bank (basically most IB's i believe) sells gold in the spot mkt to raise cash.
3. bullion bank lends cash elsewhere for market interest rate, arbing the difference
so it serves both parties... it creates credit from the central bank's pov, and it's a profitable arb from the bullion bank's pov. the only problem with this form of credit creation is that recovering the physical gold in the spot mkt creates monetary instability as gold shoots vertical. it's a real problem. the credit orgy just went way too far. central banks worldwide have lent out 30-50% of their physical metal
