Caribbean Banking Centers aggregate timeseries (offshore HF proxy)
Sum of US Treasury holdings across the 5 Caribbean Banking Centers (Cayman Islands, Bermuda, Bahamas, Curacao, British Virgin Islands) for each month where members are individually disclosed. Useful as a proxy for offshore hedge-fund / SPV capital flow into US Treasuries: rapid CBC growth typically signals leveraged-fund inflows, while stagnation / decline indicates central-bank-reserve dominance (Japan / China). Caveat: smaller members (Bahamas / Curacao / BVI) may fall into the 'All Other' bucket some periods, slightly under-counting true offshore aggregate.
