SKN | Bank of America Flags Deleveraging Risk as Bond-Market Volatility Surges

Key Takeaways:

• Bank of America is warning that a sharp increase in Treasury-market volatility could raise the risk of broader deleveraging across financial markets.
• Strategist Michael Hartnett highlighted a 35% two-day surge in the MOVE Index as a signal of growing stress within the Treasury collateral system.
• The bank sees the combination of higher yields and elevated volatility as more significant than high borrowing costs alone because leveraged investors may be forced to reduce positions.
• Bank of America still expects rising yields to represent the most likely threat to the current market and economic expansion, while anticipating potential policy intervention if stress becomes severe.

Bank of America is raising a specific risk-management concern for financial markets: a sharp increase in bond-market volatility could transform elevated Treasury yields into a broader deleveraging event. Strategist Michael Hartnett’s analysis places the focus on the interaction between higher yields, volatility and leverage, rather than on interest rates alone.

Bank of America Sees Stress Building in the Treasury Market

Hartnett highlighted a 35% surge in the MOVE Index over two days, describing the move as a signal of increasing stress within the Treasury collateral system. The MOVE Index measures volatility in U.S. government bond markets, making a rapid increase particularly relevant for leveraged financial positions that depend on stable collateral values and funding conditions.

For Bank of America, the concern is that continued volatility could force investors using leverage to reduce exposures. That process can create a feedback loop in which position reductions generate additional market pressure across bonds and, potentially, equities and other risk assets.

The Risk Is the Combination of Yields and Volatility

Bank of America’s warning is not simply that Treasury yields remain elevated. The bank is focused on the combination of elevated yields and rapidly rising volatility.

Higher yields increase financing costs and can pressure asset valuations. When those conditions are accompanied by greater volatility, leveraged investors can face additional risk-management demands, including collateral adjustments and position reductions. Hartnett therefore sees the bond market as a potential transmission mechanism through which stress could spread beyond fixed income.

Bank of America Identifies a Second Risk-Off Scenario

Hartnett also highlighted a separate combination that could signal tightening financial conditions: bond yields continuing to rise even as oil prices decline. Such a move would suggest that rising yields are being driven by factors beyond energy-related inflation.

This distinction matters for Bank of America because falling oil prices would normally reduce some inflationary pressure. If yields nevertheless continued higher, the bank would interpret that as evidence of broader financial tightening, potentially increasing pressure on leveraged positions and risk assets.

Why Bank of America Is Watching Policy Response

In its baseline assessment, Bank of America continues to view rising yields as the most likely threat to the current economic and market expansion. The bank’s analysis nevertheless leaves room for policymakers to respond if financial stress becomes sufficiently severe.

Hartnett expects that significant market stress could eventually prompt policy intervention, potentially placing a ceiling on yields and weakening the U.S. dollar. For sophisticated wealth holders, the important signal is therefore the transmission mechanism: Treasury volatility can affect funding, collateral, leverage and ultimately broader portfolio conditions. Monitoring the bond market is consequently central to understanding whether current market strength remains supported by stable financial conditions.
