A country's bond yield reflects market confidence in its ability to repay debt. The US 30-year yield crossing 5% is a stress signal. Critically, this is now a global phenomenon across G7 nations, indicating widespread lack of faith in the world's leading economies and leaving no safe haven.

Don't wait for public credit spreads to blow out as a warning sign. In a system where sovereign debt is the primary vulnerability and corporates are easily bailed out, credit spreads have become a coincident, not leading, indicator. The real leverage risk is hidden in private credit.

Unlike the post-GFC era, governments now lack the fiscal and monetary flexibility to cushion every economic shock due to high debt levels. This is forcing global markets to trade on their own fundamentals again, creating volatility and relative value opportunities reminiscent of the pre-2008 era.

Unlike past crises like 2008, the coming debt sustainability crisis will be different because the government's own balance sheet is the source of the instability. This means it will lack the capacity to bail out the market in the same way, fundamentally changing the nature of the crisis.

Despite recent concerns about private credit quality, the most rapid and substantial growth in debt since the GFC has occurred in the government sector. This makes the government bond market, not private credit, the most likely source of a future systemic crisis, especially in a rising rate environment.

Persistently low high-yield credit spreads, despite global turmoil, don't signal corporate health. This is a structural market shift where the riskiest debt has migrated from public markets to the opaque world of private credit, artificially suppressing spreads and hiding true risk.

Credit spreads are becoming an unreliable economic signal. The shift of issuance to private markets reduces the public supply, while the Federal Reserve's 2020 intervention in corporate debt markets permanently altered how investors price default probability.

For 40 years, falling rates pushed 'safe' bond funds into increasingly risky assets to chase yield. With rates now rising, these mis-categorized portfolios are the most vulnerable part of the financial system. A crisis in credit or sovereign debt is more probable than a stock-market-led crash.

Massive government issuance is crowding out private credit and making sovereign bonds inherently riskier. This dynamic is collapsing credit spreads and could lead to a market where high-quality corporate bonds are perceived as safer than government debt, challenging the concept of a 'risk-free' asset.
