Global bond sell-off deepens amid fears over inflation and AI issuance

Long-term government borrowing costs have reached multi-decade highs, according to the Financial Times, as the global bond sell-off deepens. The move is being driven by renewed fears over inflation alongside expectations of increased issuance linked to artificial-intelligence investment. The report was published on August 18, 2026.

Higher long-term yields directly affect sovereign borrowing costs and feed into financing conditions for companies. AI-related issuance adds a sector-specific supply concern, but the story does not identify individual issuers, markets, or the size and timing of the expected borrowing.

The next useful markers are inflation data, central-bank guidance, auction demand and disclosures from companies or governments planning major borrowing programmes. Without ticker-specific enrichment or quantified moves beyond the reported multi-decade highs, the read remains a macro risk signal rather than a defined single-name setup.
