Global government borrowing costs have surged to multi-decade highs, driven by persistent inflation concerns, substantial government deficits, and a significant increase in corporate debt issuance, particularly for AI-related investments. Geopolitical tensions, notably the conflict involving Iran and the US, are exacerbating inflation fears and contributing to market instability. The sheer volume of corporate bonds being issued is also seen as a factor competing with government debt. While the US Treasury has announced measures to support the bond market, their impact has been temporary, and yields continue to climb across major economies, including the UK, Germany, and Japan. This rise in borrowing costs affects everything from consumer mortgages to government debt servicing, signaling broader economic challenges.
