Burnham answers 5% gilt yields with pension savings that begin in 2030

Burnham named his audience before the speech. On the 26th, ahead of the conference, he said the government needed to send a signal to markets that it was facing up to the reality of the public finances ^[11]. He said it with the 10-year gilt yield above 5%, near its highest level since the 2007 financial crisis ^[10]. The triple lock is where the long-run pension bill sits. It lifts the state pension each year by the highest of inflation, wage growth or 2.5% ^[2], and in July the Office for Budget Responsibility warned that keeping it could push pension spending to as much as 9% of GDP several decades from now ^[3].

Labour's 15 billion pounds a year is a 2040 number ^[12], a decade after the rule takes effect in 2030 ^{[5] [3]}. The 50 billion projected for 2050 is 3.3 times that ^[2]. It grows because the thing being removed compounds: under the old rule a pension raised once becomes the starting point for the next increase ^[4]. The restraint bites in years when workers' real incomes rise sharply ^[19], and the Financial Times said the change still protects pensioners from inflation shocks ^[20].

Labour has earmarked the saving for care ^[14], so none of it is set aside for debt. Ruth Curtice, chief executive of the Resolution Foundation, said the plan could improve a care system that is currently at breaking point ^[15]. The report does not say how gilts traded after the speech.

For a gilt holder the plan can go three ways. The care service could be phased in at the pace the savings arrive, leaving borrowing about where it was. It could instead start in the next parliament, ahead of the money, with the gap met by taxes or new debt. Or a later government could keep the pension rule and shrink the care promise, and only in that version does the 50 billion a year reduce the deficit.

In my view the case that 5% yields now bind even Labour's most protected spending is half right. The yield moved the politics ^[11]. Burnham, two months after taking over from Keir Starmer ^[8], said he accepted that there could be a political price to pay, adding that someone has to endure the pain and rip the plaster off ^[9]. The borrowing path to 2029 is untouched ^[1], and I would not reprice gilts on this reform alone. The counter-case is that bond buyers price a government's willingness to take pain on pensioners well before the savings show up. The yield will settle it. A sustained fall back below 5% after the speech, with no other news to explain it, would favour the counter-case; a care bill that starts before 2030 with no tax attached would favour mine.
