Jamie Dimon Warns London Tower Plans Hinge on Starmer Staying in Power

JPMorgan CEO Jamie Dimon warned Wednesday that the bank could revisit its planned multibillion-dollar London tower if UK Prime Minister Keir Starmer loses power, CNBC reported. Dimon made the remarks in a Bloomberg interview in Paris. He said a hostile successor government toward banks would force a rethink of JPMorgan’s footprint in the UK capital.

A Landmark Project Now Under Political Scrutiny

Late last year, JPMorgan announced plans to construct a new three-million-square-foot tower in London’s Canary Wharf district. The building would house up to 12,000 employees and serve as the bank’s UK headquarters. Construction is projected to span six years. A renovation of the bank’s existing Bank Street building would run concurrently. At the time of the announcement, JPMorgan attached a condition. Plans were subject to a “continuing positive business environment” in the UK. That caveat now looks prescient.

Dimon also flagged the significant tax costs already absorbed by the bank. He said JPMorgan had paid roughly $10 billion in additional taxes connected to the construction project. The bank currently employs more than 20,000 people across the UK. Its London operations alone are estimated to contribute £7.5 billion annually to the local economy.

Background: Labour’s Political Crisis

Starmer’s grip on power has weakened sharply following his Labour Party’s poor performance in last week’s local elections. Right-wing Reform UK and the left-wing Green Party made substantial gains. Within days, roughly 90 Labour MPs called publicly for Starmer to resign. More than 100 others signed a statement backing him to remain. Starmer defied those calls on Tuesday, insisting he would stay on.

The political turmoil rippled quickly through bond markets. UK government bonds, known as gilts, sold off across the curve on Tuesday as uncertainty spiked. By Wednesday morning they had recovered some ground as investors interpreted Starmer’s defiance as a stabilising signal.

Dimon Praises Starmer and Reeves Despite Uncertainty

Despite his warning, Dimon made clear he personally supports the current UK leadership. He described Starmer as a “very smart guy” navigating an inherited debt and deficit problem. He also said he holds Finance Minister Rachel Reeves in high regard. Both, he argued, are making politically difficult but economically necessary decisions.

Dimon also praised Starmer’s effort to rebuild UK ties with Europe after Brexit. He referenced earlier conversations between Starmer and French President Emmanuel Macron about deeper military, intelligence, and economic cooperation. He stressed this did not mean reversing Brexit but rather building practical alliances beneficial to both sides.

Starmer was scheduled to meet key cabinet colleagues on Wednesday as he works to consolidate support inside his party.
