Bond Markets Plunge as Inflation Fears Mount, Fiscal Pressures Bite

Global bond markets are experiencing significant stress as long-term borrowing costs have hit their highest levels in decades. This is largely due to renewed inflation worries, particularly after oil prices rose above $90 a barrel. In the US, 30-year bond yields reached their highest since 2007, while Japan's 10-year borrowing costs surpassed 3% for the first time in three decades.

The situation is further complicated by concerns over fiscal pressures facing major economies, with some countries struggling to manage high government debt levels. Kjersti Haugland, chief economist at DNB Carnegie, noted that bond markets are entering a period of greater uncertainty and rising inflation risks.

Investors are also wary of the impact of AI hyperscalers on capital competition, as well as budget deficits and concerns over the Federal Reserve's communication under new Chair Kevin Warsh. The selloff in government bonds has far-reaching implications for economies worldwide, setting borrowing costs for companies and other loans such as mortgages.
