The head of JP Morgan Chase authorized on a significant £3 billion office complex in the UK capital after commitments from UK government officials about business-friendly measures.
The major US bank, which along with another major bank revealed major UK investments shortly following avoiding higher taxes in the Treasury's financial statement, authorized the project the previous week.
This authorization came after a meeting to the United States by Varun Chandra, who held discussions with Jamie Dimon to discuss commitments about the UK's economic approach.
The discussions happened days before the Treasury revealed revenue-raising measures in a financial statement that spared financial institutions from increased charges, following intense lobbying from the financial sector.
"The development ... would likely not have proceeded if this economic statement had been perceived as against business interests."
On this week, the banking giant announced plans to develop a 3 million square foot headquarters in Canary Wharf, which will become its new UK headquarters and house more than half of its London employees.
The company emphasized that the development would rely on "favorable economic conditions in the UK".
The bank has indicated that the development could contribute substantial economic value to the UK economy over the next six years.
The government official stated she was thrilled about the project, calling it a "massive endorsement in the UK economy".
A source familiar with the bank's investment strategy said that the project approval was "based on multiple factors" and that "it was impossible to predict whether financial institutions were going to be facing higher charges before the budget".
The JP Morgan chief stated that the "British authorities' focus of financial development has been a key consideration in supporting our this decision".
Another major bank announced that it would increase its UK regional presence and employ new employees, in a strategy that would substantially expand its workforce in the Britain's second largest metropolitan area.
The Treasury had considered increasing the bank levy in the UK, as it explored approaches to generate funds after opting not to implement additional income levies, but ultimately decided against the measure.
Financial institutions in the UK currently pay a 28% corporation tax rate, that is exceeding the typical percentage, as well as a separate levy on their domestic financial positions.
