All three comparisons use daily closing observations for September 25 and October 1, 2026. FRED’s October 5 updates added October 2 readings of 12.02% for CCC-and-lower debt, 3.10% for broad high yield and 0.85% for investment-grade debt. All three eased from October 1 while remaining above their September 25 levels.
The investment-grade move is the clearest evidence that repricing extended beyond the lowest-rated debt. CCC-and-lower bonds are already included in the broader high-yield index, so those two increases are overlapping evidence. The picture is broader but unequal pressure.
How credit spreads could reach Bitcoin
For Bitcoin, transmission would depend on how credit repricing changes capital costs and risk-taking. If financing becomes more expensive, leveraged investors may need to shrink positions. Institutions could reduce crypto exposure as they reassess how much risk they are willing to carry across their portfolios.
The authors of the 2023 IMF working paper The Crypto Cycle and US Monetary Policy describe a related mechanism. Their historical analysis finds that monetary tightening can raise capital costs, encourage crypto investors to reduce leverage and lower aggregate crypto prices, with institutional participation reinforcing transmission.
The paper examines historical monetary-policy shocks; the current figures measure corporate credit premiums. Applying its mechanism to this episode remains conditional. The spread observations establish credit repricing, while current Bitcoin selling and its cause remain unestablished.
The Chicago Fed National Financial Conditions Index provides a broader check. Its latest reading was -0.548 for the week ending September 25, released September 30. That negative value indicates looser-than-average financial conditions. The observation predates the newest spread readings.
The next test is whether widening persists beyond the weakest borrowers and coincides with worsening broad financial conditions and weaker Bitcoin demand. That combination would strengthen the case for wider pressure on institutional risk-taking. Narrowing spreads and resilient Bitcoin demand would weaken it.
