New Bitcoin ETF outflows are exposing BTC to Wall Street’s most crowded trade

A notable development has hit the crypto markets. Bitcoin ETF outflows are turning rising Treasury yields into a direct test for BTC price after Bank of America’s May Global Fund Manager Survey showed professional investors cut bond allocation to a net 44% underweight, the deepest positioning since June 2022, down from 33% underweight in April. At the same time, managers pushed global equity exposure to a net 50% overweight from 13% in April, while cash fell to 3. Fund managers are rotating into risk while rejecting duration, doing so at the fastest pace in nearly four years.

For Bitcoin, that combination creates a problem the asset cannot ignore, as 40% of surveyed managers named second-wave inflation as the biggest tail risk, and 18% named a disorderly rise in bond yields. The US 10-year yield hit 4. 6653% on May 19, its highest level since January 2025, while the 30-year reached 5.

Market Dynamics

14% and the 10-year real yield climbed to 2. Real-yield repricing raises the hurdle rate for every non-yielding asset, and Bitcoin yields nothing. Global fund managers cut bond allocations to a net 44% underweight in May while lifting equity exposure to a net 50% overweight.

The anti-duration trade is now crowded At net 44% underweight, the anti-bond position has become the dominant consensus trade in BofA's survey over recent history, making the next move in Treasury markets disproportionately important for risk assets. When yields climb, duration gets repriced, borrowing conditions tighten, and capital either seeks safety or exits risk. As a 24/7 liquid asset with no contractual cash flows, Bitcoin tends to absorb that selling before less-liquid positions are cut.
