The Bank of England said this year's stress test of major UK banks will measure how non-core capital buffers stand up to market and economic stresses.
The test, introduced since the financial crisis a decade ago forced British taxpayers to bail out several lenders, has focused on the resilience of a bank's core capital buffer.
But the Bank of England said today that this year's test would also include secondary buffers held by the banks to reflect their domestic and global systemic importance.
The bank said the "uplifts" assumed from including a systemic risk buffer would add 2.5% to the overall hurdle rate of Lloyds Banking Group.
It would also 1% to those of Barclays, HSBC, Royal Bank of Scotland - which owns Ulster Bank here - Santander UK and Nationwide.
The Bank of England also said it was making changes to how it assesses another secondary buffer knows as Pillar 2A, a measure of financial strength that assesses a bank's capacity to manage risk.
However, the changes being made specifically to the treatment of Pillar 2A capital in the test mean that "on average, hurdle rates are expected to be lower than they would be under the previous calculation" for that buffer.
The result of this year's test is due around the end of the year.
