Gold and Bitcoin ETFs drew a combined record of roughly $7 billion over five US trading sessions, with SPDR Gold Shares taking in about $3.4 billion and BlackRock's iShares Bitcoin Trust attracting roughly $1.5 billion; together GLD and IBIT supplied about 70% of the inflow and ranked among the top 10 US ETFs by weekly flows. GLD now manages more than $150 billion and IBIT around $60 billion. The rush accompanied Bitcoin's move above $80,000 and gold's rise above $4,600 an ounce as investors sought protection from US debt above $40 trillion, a softer dollar, and Treasury's Aug. 19 decision to at least double longer-dated liquidity buybacks to $4 billion per operation. Bitwise's Matt Hougan argued a traditional 60/40 portfolio is fully exposed to fiat currency, while Strive's Matt Cole and Bernstein framed Bitcoin's fixed 21 million supply as increasingly suited to capture scarce-asset demand if policymakers favor debasement over fiscal restraint. BlackRock research published this month said a 1% to 2% Bitcoin allocation could have improved 60/40 risk-adjusted returns, though strategists still note Bitcoin's higher volatility and shorter defensive record leave the durability of the co-inflow unproven if the dollar strengthens or real yields rise.
