summary: "Investors sold off long-dated securities across major economies on Tuesday, pushing borrowing costs to their highest levels in decades. The rout, which spanned markets from the US to Japan, was fueled by persistent inflation and mounting fiscal deficits. A surge in bond issuance aimed at financing the AI boom added further pressure to sovereign debt markets, as investors demanded higher yields to offset risks. Crude oil prices holding above $90 intensified the downturn, while longer-maturity bonds became the focal point of anxiety regarding the costs of AI development and government spending. This shifting sentiment increases the cost of servicing national debt, forcing governments to pay higher premiums to attract buyers for their longest-dated obligations."
