Introduction: Global bond sell-off hits Japan
Good morning, and welcome to our rolling coverage of business, the financial markets and the world economy.
The global sell-off in longer-term government debt is continuing, as concerns mount over fiscal sustainability and the health of the global economy.
After losses across the bond and equity markets yesterday, there are fresh falls in Asia-Pacific markets today.
Japan is now in the firing line from bond vigilantes, who are driving up borrowing costs (yields) by selling government debt, pushing down prices.
The 30-year Japanese government bond yield has hit an unprecedented 3.255% today, Reuters reports, following the jump in UK, US and eurozone bond yields on Tuesday
Yields on Japan’s 20-year government bonds rose to levels last seen in 1999.
Bond yields especially on super-long-dated 30-year tenors have been soaring around the world, with investors anxious about the scale of debt in countries from Japan to the US. The 30-yr JGB yield hit an unprecedented 3.255%, ffg a run-up in similarly dated gilts and Treasuries https://t.co/LpbRqlDnSN pic.twitter.com/H8MrsBTbAF
— Kong Kong Kubs (@3benson) September 3, 2025The sell-off appears to be being driven by several factors, including concerns over rising government debt levels, opposition to measures to cut borrowing, sticky inflation, and economic growth prospects.
Ipek Ozkardeskaya, senior analyst at Swissquote Bank, explains:
Investors are demanding higher returns to hold bonds exposed to both inflation risk and elevated debt levels. Higher yields, in turn, push up borrowing costs for companies and weigh on valuations.
As a result, equities and corporate bonds also kicked off the week on a weak note.
Bond investors will be watching London and Paris closely today.
Rising bond yields are a political headache for Rachel Reeves, as it eats into the UK chancellor’s headroom to have debt falling in five years’ time. It could force Reeves into further tax rises, despite concerns that this would weaken growth, or spending cuts, despite opposition from her own party.
The potential collapse of the French government next week, in a row over proposed spending cuts, are also worrying investors.
Mujtaba Rahman, managing director for Europe at Eurasia Group, explains:
The French Prime Minister François Bayrou will lose on Monday 8 September a gamble that he was never likely to win and will almost certainly be ejected from office by a parliamentary confidence vote of his own choosing;
President Emmanuel Macron has ruled out a new legislative election—for the time being—and will appoint his fifth Prime Minister in 21 months, almost certainly from within his center and center-right coalition.
The new PM will be obliged to make concessions on Bayrou’s ambitious plans to cut 0.8% of GDP (nominally €43.8bn) from France’s deficit next year.

Pound under more pressure
The pound is dropping in early trading, adding to sharp losses yesterday.
Sterling has dropped by a quarter of a cent to $1.3366, close to the one-month low touched on Tuesday.
Yesterday the pound lost one and a half cents, its biggest daily drop since April, as the drop in government bond prices rocked the markets.
