Healy Becomes UK Chancellor, Gilts Under Pressure as Yields Rise to 5.04%
Claire Weston
New PM Andy Burnham surprised markets by naming former Defence Secretary John Healey as Chancellor; 10-year gilt yields rose to 5.04% on day one, a clear signal that investors want fiscal credibility before spending promises.
Why did this pick catch markets off guard?
The frontrunners were Home Secretary Shabana Mahmood and Energy Secretary Ed Miliband. Healey was not on most shortlists.
His Treasury experience is thin — he served as a junior Treasury minister from 2002 to 2007 but was never in the fiscal inner circle.
This means → Burnham chose someone who will execute the PM's agenda, not champion an independent fiscal vision. Put simply = he picked a loyal steward, not a co-pilot.
What did gilts signal on day one?
10-year gilt yields climbed 0.08 percentage points to 5.04% on Burnham's first day. French and Italian bonds of the same maturity rose just 0.02 points.
This means → UK debt underperformed its European peers — investors effectively cast a no-confidence vote on the new government.
The backdrop is already strained: UK borrowing costs hit 5.2% in May — the highest since 2008 — and annual debt-interest payments now exceed £100 billion.
Why didn't Burnham's fiscal pledges calm markets?
Burnham said he would "follow existing fiscal rules" but also flagged using "flexibility within the rules" and floated raising the personal income-tax allowance.
The Resolution Foundation estimates that unfreezing the personal allowance alone would cost £3.7 billion by 2029–30 — and "there is no spare cash."
In plain terms = promising discipline and hinting at higher spending in the same breath sends a contradictory signal.
How are institutional investors reading this?
Aegon Asset Management CIO Stephen Jones: "All we have so far are hints that spending will rise and reform will fall. Markets need more detail."
Ninety One's John Stopford noted the sensitivity "shows the margin for error is razor-thin" and that Burnham "needs to establish fiscal credibility."
Capital Economics' Paul Dales warned of a repeat of former Chancellor Rachel Reeves' misstep — loosening fiscal policy while inflation pressures build. The Iran conflict has already pushed oil prices higher, making the risk real.
What is the core question from here?
W1M fixed-income co-head James Carter framed it clearly: "Maintaining market confidence is one of the most effective ways any PM can create room to govern — and that demands discipline in both policy and communication."
UK borrowing costs are already the highest in the G7. Whether Healey can balance fiscal discipline against Burnham's spending agenda is the question markets will keep asking.
This reflects a deeper tension: the new PM wants to spend, but the bond market is already drawing red lines.
