Bond markets turn higher rates into a global reckoning
Breaking down the bond market
Government bonds set the cost of money worldwide, making their shift from decades of falling yields a test of how economies absorb inflation, debt, and deficits.
- 1US government bonds anchor global borrowing costs, shaping mortgages, businesses, and financing conditions far beyond American borders.
- 2The post-2020 return of inflation, growth, and higher rates ended a decades-long bond bull market and changed the market’s logic.
- 3Heavy debt may produce a chronic deterioration in borrowing conditions rather than an immediate crisis, leaving governments vulnerable to investors’ demands.
Don't miss
Robin Wigglesworth’s distinction between an acute debt crisis and a chronic deterioration in borrowing conditions reframes what bond-market danger can look like.
The brief
Katie Martin and Robin Wigglesworth begin with a market many people find opaque but economies cannot escape: government bonds are the foundation of global finance.
US government bonds sit at the center because their borrowing costs help set the price of money elsewhere, influencing mortgages, businesses, and other countries’ financing.
The bond bull market’s long decline in yields gave way after 2020 to inflation, stronger growth, and higher rates, with oil and geopolitical shocks adding pressure.
The central tension is whether mounting debt and deficits trigger an acute crisis or a slower deterioration; Wigglesworth argues that high debt alone does not guarantee a sudden break.
