On 7 October the yield on the UK 30-year gilt rose 13 basis points to a peak of 6.036% at 13:41 GMT, the highest since January 1998, Reuters reported. The 10-year yield rose about 10 basis points. The move mirrored a global sell-off in long-dated debt: Bloomberg said US 30-year yields were back at their 2002 high with oil above
A 30-year yield above 6% means that every pound of new long-term borrowing costs more, and that the interest bill on the national debt grows. It narrows the Chancellor's room for manoeuvre at the point he is also being asked to fund defence and help households. The sell-off is global, but sterling and gilts are the assets investors punish first when they doubt a budget.
Mortgage and business loan prices follow gilt yields with a lag. If you fix this year, expect higher quotes than a month ago. If you hold cash, savings rates may stay high. If you own a UK pension that holds gilts, the capital value falls as yields rise, though new income is higher.
The market is telling the Chancellor that he cannot borrow more. The Budget has to show credible tax rises or spending restraint, and quickly.
This is a world story, not a British one: US and French yields are rising too, and oil is the cause. Strong demand at the 2031 gilt auction shows investors still lend to the UK on fair terms.
Judge the Budget by its effect on the 30-year yield in the week after 28 October, not by the headlines on the day. A Budget that pulls the yield back below 6% earns the Chancellor room. One that pushes it to a new high will mean the Bank of England and the markets, not the Treasury, are setting policy.

The 30-year gilt yield hits 6.036%, a 28-year high, and the FTSE 100 drops 0.8%. Healey's Budget is three weeks away
A global bond sell-off and oil back above $100 pushed UK long-term borrowing costs to their highest since January 1998. The Treasury says the Chancellor is sticking to his fiscal rules.
The cost of the British government's longest borrowing climbed to a 28-year high on Wednesday. The yield on the 30-year gilt rose 13 basis points on the day to peak at 6.036% at 13:41 GMT, the highest since January 1998, Reuters reported. It first broke through 6% a week ago, as City AM reported, and the FTSE 100 had already fallen 2.2% in the week to 2 October, its worst week since April. Wednesday's move is therefore a second leg of a sell-off, not a one-day shock. The 10-year yield rose by about 10 basis points as well. The move was not made in London alone. US 30-year Treasury yields returned to their highest since 2002, Bloomberg reported, with oil back above $100 a barrel, and France's bond market was under strain, though the head of the Banque de France said the European Central Bank did not need to intervene. Demand at home held up: the Debt Management Office sold £1 billion of 2031 gilts at an average yield of 4.842%, with a bid-to-cover ratio of 4.39. The pound slipped from about $1.325 in the morning to roughly $1.3213 late in the day, after the dollar gained on higher oil and expectations of further Federal Reserve rate rises, StoneX noted.
Shares fell with bonds. The FTSE 100 closed down 0.79% at 10,458.50, according to Yahoo Finance and BBN Times data. Banks led the decline: Prudential lost 4.6%, Standard Chartered 4.5% and HSBC 4.2%, with Asia-focused lenders hit hardest. The politics is plainer than the market. Chancellor John Healey presents his first Budget on 28 October, and the Bank of England decides on rates soon after. Reuters reported that the finance ministry said he stressed fiscal credibility and reaffirmed the government's fiscal rules, and that Bank of America economists expect the Budget to raise public borrowing. Pressure is coming from several directions at once. The IMF's Kristalina Georgieva urged governments to rein in spending, the Financial Times reported, and the Guardian's morning briefing asked whether it is time to end the Bank of England's independence. The Chancellor must now persuade bond investors, not just voters, that the sums add up. Higher gilt yields also feed into mortgage and business loan pricing, which is why a single number on a Bloomberg screen can reach a kitchen table within weeks. The Times reported that house prices are flat amid concern about inflation. Elsewhere in the City, the FT said HSBC plans sweeping job cuts in its UK wealth business as it pushes into artificial intelligence, and the Times reported that a top UK builder is pulling out of London because the economic case has "evaporated". The next test is the Budget itself, twenty-one days away, and the market will not wait politely until then.
