Banking Notes- BASEL III

Basel III (or the Third Basel Accord) is a global, voluntary regulatory standard on bank capital adequacy, stress testing and market liquidity risk. It was agreed upon by the members of the Basel Committee on Banking Supervision in 2010–11, and was scheduled to be introduced from 2013 until 2015; however, changes from 1st April 2013 extended implementation until 31 March 2018. The third installment of the Basel Accords (see Basel I, Basel II) was developed in response to the deficiencies in financial regulation revealed by the late-2000s financial crisis. Basel III was supposed to strengthen bank capital requirements by increasing bank liquidity and decreasing bank leverage.

Key principles of BASEL III :

Capital requirements:
The original Basel III rule from 2010 was supposed to require banks to hold 4.5% of common equity (up from 2% in Basel II) and 6% of Tier I capital (up from 4% in Basel II) of "risk-weighted assets" (RWA).[3] Basel III introduced "additional capital buffers", (i) a "mandatory capital conservation buffer" of 2.5% and (ii) a "discretionary  counter-cyclical buffer", which would allow national regulators to require up to another 2.5% of capital during periods of high credit growth.


Leverage ratio:
Basel III introduced a minimum "leverage ratio". The leverage ratio was calculated by dividing Tier 1 capital by the bank's average total consolidated assets; The banks were expected to maintain a leverage ratio in excess of  3% under Basel III. In July 2013, the US Federal Reserve Bank announced that the minimum Basel III leverage ratio would be 6% for 8 Systemically important financial institution (SIFI) banks and 5% for their insured bank holding companies.
Liquidity requirements: Basel III introduced two required liquidity ratios. The "Liquidity Coverage Ratio" was supposed to require a bank to hold sufficient high-quality liquid assets to cover its total net cash outflows over 30 days; the Net Stable Funding Ratio was to require the available amount of stable funding to exceed the required amount of stable funding over a one-year period of extended stress.
Tier I Capital:
Tier 1 capital is the core measure of a bank's financial strength from a regulator's point of view. It is Bcomposed of core capital, which consists primarily of common stock and disclosed reserves (or retained earnings), but may also include non-redeemable non-cumulative preferred stock. The Basel Committee also observed that banks have used innovative instruments over the years to generate Tier 1 capital; these are subject to stringent conditions and are limited to a maximum of 15% of total Tier 1 capital. This part of the Tier 1 capital will be phased out during the implementation of Basel III.

Tier II Capital:
Tier 2 capital, or supplementary capital, include a number of important and legitimate constituents of a bank's capital base. These forms of banking capital were largely standardized in the Basel I accord, issued by the Basel Committee on Banking Supervision and left untouched by the Basel II accord. National regulators of most countries around the world have implemented these standards in local legislation. In the calculation of regulatory capital, Tier 2 is limited to 100% of Tier 1 capital.
