Explainer-What's behind the selloff in world bond markets?

Global bond markets have been experiencing a sell-off due to concerns about rising inflation, higher interest rates, and increasing government debt loads. Inflation and higher borrowing costs have pushed bond yields to multi-decade peaks for the United States, Germany, Japan, and Britain. These elevated yields could negatively impact households, companies, and government finances.

The U.S. debt pile has surpassed $40 trillion, with debt as a share of economic output reaching or exceeding 100% in most G7 countries, excluding Germany.

Key factors contributing to this bond market downturn include a hawkish speech by U.S. Federal Reserve Chair Kevin Warsh at the Jackson Hole symposium, tensions between the U.S. and Iran leading to higher oil prices, and AI hyperscalers issuing an unprecedented $220 billion in debt to fund their investments. While central banks have the power to buy bonds to stabilize markets, the bond vigilantes remain alert, as they seek to impose fiscal discipline on profligate governments by demanding higher compensation for buying their bonds.
