Bond markets grow weary of tired deficit playbook - Breakingviews

The shift in sentiment suggests that investors are increasingly questioning the sustainability of repeated large-scale government borrowing. For years, the "deficit playbook" involved issuing debt to fund stimulus, assuming low interest rates would keep carrying costs manageable. Now, bond markets appear less willing to absorb that supply without demanding additional compensation for longer-term risks, such as persistent inflation or eroding fiscal credibility.

This matters for the broader economy because government borrowing costs influence everything from mortgage rates to corporate financing. If investors hold a firm line on yields, policymakers may face tougher trade-offs between supporting growth and reining in deficits. The focus is likely to remain on upcoming debt auctions and central bank messaging, particularly any hints about quantitative tightening or balance sheet reduction. How governments adapt their issuance strategy and spending plans will be a key signal for market stability.
