JPMorgan Chase chief Jamie Dimon warned that a hostile UK government could force the bank to abandon a £3 bn London office project, sparking debate among executives.

Dimon’s concerns focus on sector‑specific taxes that could distort markets without raising substantial revenue. He cites an alleged $10 bn in extra taxes paid, though the bank’s UK tax bill last year was under $1 bn, highlighting the gap between perception and reality.

The proposed office could inject an estimated £10 bn into the UK economy over six years, yet the threat of cancellation seems unlikely given the bank’s decade‑long land ownership and the city’s acute office shortage.

Business leaders now face a dilemma: voicing grievances risks political backlash and investor discounts, while staying silent may let costly policy uncertainty persist.
