Exchange-traded funds (ETFs) tracking gold and Bitcoin have collectively attracted $7 billion in the past five trading days, marking a record net inflow, according to data compiled by Bloomberg. Among these, State Street's SPDR Gold Shares (GLD) saw a net inflow of nearly $3.4 billion, and BlackRock's iShares Bitcoin Trust ETF (IBIT) recorded a net inflow of $1.5 billion. Both funds ranked among the top ten U.S. ETFs by inflows this week. This wave of capital was driven by renewed market concerns over the U.S. debt burden, the dollar's trajectory, and efforts to manage long-term yields. The immediate trigger was U.S. Treasury Secretary Scott Bessent's proposal to at least double the size of long-term Treasury buybacks.
