i hoping we will find that out when a new administration takes over in january. when they start blaming each other for the economic problems, they may shed some truth on this matter. there are tens of billions worth of treasuries being held in caribbean countries without any explanation.
maybe the cayman islands are home to hedge funds, and maybe there is an arm of the federal government there to buy up debt that asian, russian, and arab countries wouldn't. i think we will find out for sure when long term interest rates start moving up.
if there really are hedge funds using 10-1 or 20-1 leverage, they will blow up and go bankrupt. if we don't hear of any major bankruptcies down there, it is a good bet that the government is behind the treasury bond purchases.
