**Global debt markets came under renewed pressure on Thursday as Japan’s benchmark 10-year government bond yield surged to its highest level in 30 years**, extending a sell-off that began in US Treasuries overnight.

As Tokyo reopened following a three-day holiday, the **10-year Japanese government bond yield jumped as much as eight basis points to 3.055%**, its highest level since August 1996. The 30-year yield also climbed to around **4.125%**.

The move followed the sharpest daily increase in US Treasury yields since the market turmoil of April 2025, after stronger-than-expected US business activity revived inflation concerns and a weak five-year Treasury auction intensified selling.

The global bond sell-off matters for equities because **higher government yields raise borrowing costs and make bonds more competitive with shares**, putting particular pressure on highly valued technology companies, property stocks and other rate-sensitive sectors.

Oil added another inflationary pressure. **Brent crude remained around $103 a barrel**, after settling at $103.08 on Wednesday as investors reacted to renewed tension between the US and Iran.

Wall Street had already reacted to the rise in yields, with the **Dow falling 0.7%, the S&P 500 down 0.9% and the Nasdaq losing 1.1% on Wednesday**.

Asian equities were mixed. Japan’s **Nikkei 225 rose around 1% to 65,645**, helped by strength in semiconductor and AI-linked shares, while Hong Kong fell 0.3% and Shanghai declined 0.9%. Australia’s ASX 200 dropped 0.7%, while South Korean markets were closed for the Chuseok holiday.

For investors, the key issue is no longer just whether bond yields are rising, but **how far the repricing spreads across asset classes**. If Japanese and US yields continue climbing together while oil remains above $100, the market faces a difficult combination of **higher discount rates, higher corporate funding costs and renewed inflation pressure**.

That backdrop is generally tougher for **expensive growth shares, property companies, highly leveraged businesses and long-duration assets**, while banks, insurers and some commodity producers may prove relatively more resilient. The clearest signal to watch now is whether the **US 10-year and Japanese 10-year yields keep making new highs** — because sustained moves there would increase the risk of a broader equity de-rating rather than a short-lived bond-market correction.
