Global bond markets are attracting renewed investor demand as a sharp sell-off in artificial intelligence stocks raises concerns about corporate borrowing, expensive technology valuations and the ability of heavily indebted businesses to generate enough cash to support their expansion plans.
Government bonds rallied on October 14 and continued to attract attention on October 15, 2026, as investors reassessed the risks surrounding the artificial intelligence investment boom. The movement was notable because US inflation remained elevated, a condition that would normally complicate the outlook for bonds by increasing the possibility of higher interest rates.
The yield on the benchmark 10-year US Treasury note fell by 8.4 basis points to 5.105% on October 15, reaching its lowest level in three weeks, according to reported market data. The 10-year Japanese government bond yield also declined, falling 6.5 basis points to 2.93%, its lowest level since September 10.
The rally suggests that investors are reconsidering the balance between the potential returns from equities and the relative security offered by government debt. For much of 2026, rising inflation and higher government borrowing costs had made bonds less attractive as a defensive investment. The latest market movement indicates that concerns about slowing growth and risks linked to AI financing are becoming more influential.
However, the recovery in bond prices does not necessarily mean that financial markets have returned to stability. Investors must still contend with inflation, uncertain central bank decisions and questions about whether the enormous sums being committed to artificial intelligence infrastructure will generate sufficient returns.
The change in sentiment also matters for companies that rely on debt to finance data centres, computing equipment and other technology infrastructure. If investors become less willing to provide funding at current prices, some businesses could face higher borrowing costs and greater pressure to demonstrate that their investments can produce sustainable earnings.
For the wider capital markets, the immediate issue is whether government bonds can provide reliable protection during a period of falling share prices and increasing concern about corporate credit quality.
The relationship between stocks and bonds is changing as investors reassess risk. Government debt is attracting demand even though inflation remains a concern, while technology companies with substantial financing requirements face closer scrutiny over their spending plans and future cash flows.
