A market structure warning
The OECD’s Global Debt Report 2026 highlights a shift toward more price sensitive and leveraged investors in debt markets. Its concern is that this changing investor base can make markets more vulnerable to shocks. This is a structural observation, not a prediction of a particular selloff date.

The same news can produce different trades
An investor with stable funding may be able to hold a bond through a temporary price decline. Another holder may have to sell because of borrowing limits, collateral calls or client withdrawals. Both can assess the issuer similarly and still behave differently.
That distinction helps explain why market liquidity can deteriorate faster than credit fundamentals. It also shows why an attractive valuation is not sufficient protection for an investor who may need cash immediately.
Design around the holding constraint
Our conclusion is to consider liquidity needs before choosing a yield target. Match expected cash requirements with assets that can realistically provide cash when needed, and avoid assuming that every holding can be sold at its last displayed value.
Diversification by issuer is useful, but it does not necessarily diversify the behaviour of the funds or strategies that own those issuers. Shared financing arrangements and similar risk limits can connect apparently separate exposures.
For a portfolio review, ask what would force a sale and what resources would prevent one. That question is more useful than treating price volatility as harmless simply because a bond is intended to be held to maturity.
