The top executive of JP Morgan Chase signed off on a significant three billion pound new tower in the UK capital in the wake of commitments from government representatives about business-friendly measures.
The major US bank, which together with another major bank disclosed major UK investments hours after being spared tax increases in the UK government's recent budget announcement, formally signed off recently.
This authorization was preceded by a meeting to New York by Varun Chandra, that held discussions with Jamie Dimon to provide assurances about the UK's economic approach.
The meeting happened days before the government disclosed significant tax increases in a financial statement that spared the banking sector from increased charges, in response to substantial advocacy from the financial sector.
"The development ... would potentially been canceled if this budget had been regarded as anti-prosperity."
On this week, the banking giant revealed plans to construct a substantial tower in London's financial district, which will serve as its new UK headquarters and accommodate a significant portion of its London employees.
The bank stressed that the project would depend on "a continuing positive business environment in the UK".
The bank has indicated that the investment could contribute £9.9 billion to the national economy over the next six years.
The Treasury chief commented positively about the investment, calling it a "multibillion-pound vote of confidence in the UK economy".
A insider knowledgeable about the development project indicated that the project approval was "influenced by various considerations" and that "no one could know whether banks were going to be taxed before the budget".
The banking executive commented that the "British authorities' focus of business expansion has been a key consideration in supporting our this decision".
A second financial institution revealed that it would expand its UK regional presence and hire new employees, in a strategy that would more than double its employee numbers in the England's major regional center.
The government had examined increasing the banking charge in the UK, as it explored methods to increase income after opting not to implement increasing income tax rates, but eventually determined against the measure.
Banks in the UK face a higher corporate tax level, which is above the typical percentage, as well as a separate levy on their British operations.
