Net Stable Funding Ratio
Bank regulation - funding risk
(NSFR).
A longer-term funding measure under Basel III regulations.
The NSFR requires longer-term and less liquid bank assets to be funded by longer-term, more stable liabilities, assuming a stressed scenario.
Although subject to domestic definitions and detailed calculations and weightings, the broad objective is to ensure that a bank is not financing loans and other credit transactions with unstable short term funding, as occurred pre-2008 when many banks were funding long term loans with short term interbank funding.
The NSFR is defined as the ratio of Available Stable Funding (ASF) to Required Stable Funding (RSF):
NSFR = ASF / RSF
A ratio of 100% or greater means that the bank has enough stable funding available, to meet its requirements under this measure.
The ratio is intended to ensure a bank remains liquid for up to one year during a crisis.
This requirement is intended to be implemented by 1 January 2018.
