The UK next chancellor race is already being run in the pages of the financial press, the bond markets, and the backrooms of Westminster, even before Andy Burnham has formally taken the keys to Number 10. With Sir Keir Starmer’s resignation clearing the way for Burnham, the newly sworn-in Makerfield MP, the question of who occupies Number 11 is not merely political gossip. It is a live market question.
Lord Jim O’Neill, the economist and cross-bench peer who has been advising Burnham, has already issued a quiet warning. ‘There are clearly some people pushing to be chancellor who feel they are owed it for their support,’ he told the BBC. His advice to Burnham: figure out your priorities before you pick the person. That is a more disciplined approach than the one Westminster gossip usually produces.
Streeting, Miliband and the Bond Market Test
The UK next chancellor race, as the bookmakers have it, comes down to Wes Streeting first, Ed Miliband second. Both carry political baggage that bond markets will price in fast.
Streeting is the frontrunner, reportedly rewarded for throwing his weight behind Burnham in the leadership contest. Simon French, Managing Director, Chief Economist and Head of Research at Panmure Liberum (the firm is an investment bank, not a consultancy as has sometimes been described), calls Streeting a ‘relatively market-friendly option’ because of his pro-growth comments. The risk, French says, is that Streeting is a political animal who may be seen as using Number 11 as a stepping stone to Number 10. ‘Politics is what politics is. It’s a popularity contest,’ French observed, with the air of someone who has watched this film before.
Burnham published a piece in May 2026 examining how Labour leadership contenders would need to sell themselves to bond markets, a framing that matters: gilt investors are not going to wait patiently for a new chancellor to find their feet.
Miliband is the more politically proximate choice for Burnham: closer ideologically, and less likely to be plotting a future leadership run. Paul Johnson, former director of the Institute for Fiscal Studies, argues alignment between Numbers 10 and 11 is not a luxury. ‘You really don’t want people in Number 10 and Number 11 having very different views,’ he said. Nick Macpherson, former permanent secretary at the Treasury, told the Financial Times that Miliband has ‘the intellect, experience, and authority’ to articulate a coherent economic strategy and win market confidence.
The counterargument is Miliband’s energy record. His tenure as energy secretary, and his net-zero drive, has left him associated with the UK’s elevated energy costs relative to European peers. Whether that association is fair is beside the point for gilt markets, which trade on perception as readily as on fact. Sharon Graham, general secretary of Unite, has gone further, saying Miliband as chancellor would be a ‘noose around the neck’ of job creation, citing his opposition to new North Sea oil and gas drilling.
The Market-Favourite Outsider and the Compromise Option
Pat McFadden does not generate headlines the way Streeting or Miliband do, which may be exactly his selling point. French at Panmure Liberum believes markets would view McFadden as ‘the safest pair of hands’, with a reaction that would be either positive or neutral. He has held shadow Treasury roles, was a business minister under the previous Labour government, and currently holds the work and pensions brief, which positions him to handle welfare reform, probably the most financially consequential domestic task any chancellor will face in the next parliament.
His liability is loyalty: McFadden is closely associated with Starmer, and if Burnham wants a clean break, that association cuts against him.
Yvette Cooper is the compromise candidate. Chief secretary to the Treasury under Gordon Brown, Foreign Secretary now, politically central enough to offend nobody badly. Danni Hewson, head of financial analysis at AJ Bell, calls her ‘a middle of the road’ option but ‘a bit more of an unknown’. In a chancellor, unknown is not always a selling point.
My read is this: Burnham cannot afford a chancellor whose appointment immediately spooks the gilt market. The UK enters this transition carrying high debt, thin growth, and unresolved welfare liabilities. That context does not leave much room for a loyalty appointment that markets interpret as a political stitch-up. If O’Neill’s advice lands, Burnham’s first call should be to the Treasury, not to his backers.
The gilt market’s reaction the morning after the announcement will be the first honest verdict on whoever gets the job.
