A single data series is up-ending decades of portfolio theory. On 29 May, André Dragosch, PhD, European head of research at Bitwise, posted a chart showing that the 60-day rolling correlation between Bitcoin and 10-year US Treasury-bond futures has collapsed to its most negative reading on record.
The structural cracks he cites are real. Bitwise’s March “Macro Fault Line” report documented the deepest bear market in long-duration Treasuries in modern history—more than a 40 percent drawdown—alongside yawning deviations in once-stable correlations between bonds, commodities and foreign yields. The research pinned the shift on post-2022 inflation shocks, swelling fiscal deficits and an exodus of foreign reserve managers from US debt.
Bloomberg’s Asia wealth survey last week confirmed the migration: high-net-worth clients, once über-long dollar paper, are rotating into gold, Chinese assets and crypto, while China and other large holders keep trimming Treasury positions in favour of alternative reserves. At the same time, the term premium on the 10-year note—normally a cushion for bond investors—has failed to rise in step with deficits, hinting at latent liquidity risk.
Correlations back up Dragosch’s thesis. Bitwise data show BTC’s link to Treasuries is now far weaker than gold’s, yet the cryptocurrency has historically outperformed bullion on days when bond prices fall sharply, underscoring its appeal as “portfolio insurance” in a sovereign-debt drawdown.
For traditional portfolio managers whose models still anchor on a positive Treasury hedge, the chart Wall Street “doesn’t want you to see” is more than a curiosity—it is a sign that the 60/40 paradigm is splintering. The longer bond markets struggle to fulfil their historic safe-haven role, the louder Bitcoin’s pitch as digital, bearer-asset insurance is likely to become.
At press time, BTC traded at $105,780.
