Basel II Explained

The banking system depends totally on trust. Investors can only gain trust when they know that their money is secured. Basel II norms are designed to prevent banks from taking risks independently and don’t respect depositors’ money. The business model of any bank is to accept deposits in the form of savings or fixed deposits and to use this capital to issue loans to individuals or businesses. So the main focus of regulators should be to check how much the inflow is vs. the outflow of capital. Basel II norms focus on the minimum capital requirement of the banks and other areas.

The pillars of Basel II framework are the Minimum Capital Requirement, Supervisory Review and role, and Market Discipline and Disclosure.

#1 – Minimum Capital Requirement

This pillar ensures that the bank calculates assets based on risk, also known as risk-weighted assetsRisk-weighted AssetsRisk-weighted asset refers to the minimum amount that a bank or any other financial institution must maintain to avoid insolvency or bankruptcy risk. The risk associated with each bank asset is analyzed individually to figure out the total capital more. Now the bank will not consider only credit risk, but also operational riskOperational RiskOperational risk is the business uncertainty a company comes across in the industry while executing its everyday business operations. Such risks arise due to internal system breakdown, technical issues, external factors, managerial problems, human errors or information gap. read more associated with the assets and decide the capital requirement. The minimum capital requirement is 8% of the risk-weighted assets per Basel II.

#2 – Supervisory Review and Role

Regulations are of no use if proper supervision is not done. As per Basel II, it is the primary duty of the supervisor to ascertain that the bank has covered enough capital that will deal with operational, credit, and market riskMarket RiskMarket risk is the risk that an investor faces due to the decrease in the market value of a financial product that affects the whole market and is not limited to a particular economic commodity. It is often called systematic more of the assets that the bank has invested in. So the supervisor can intervene in the daily operations to ensure that capital doesn’t fall the desired threshold. Therefore, the review role of the supervisor should be extremely strong and should always try to maintain the capital above the required level.

#3 – Market Discipline and Disclosure

Nowadays, markets are extremely disciplined. There are informed market participants who are well informed about the minimum requirement of capital by the banks. So if any time bank drops below the desired level of capital requirement, then market participants can identify it with the disclosures made by the banks. So this helps investors to make informed decisions. Basel II has stated banks to make full and timely disclosures.


The minimum capital requirement is very crutial for any bank. The one-time capital requirement was based on the asset that the bank used to hold. Each asset is not equal, risk-wise. So if we think practically, if the bank is holding a very risky asset and a very safe asset, should the capital reserve kept for default be the same for both the assets? No. It should be higher for risky investments and lower for less risky assets. However, the norm states that the banks should maintain a minimum capital reserve of 8% of risk-weighted assets.


Basel II’s main objective is to make the banking sector extra cautious while handling highly risky assets. The capital requirement is based on risk-weighted assets now, so banks will have to charge extra spread while issuing loans to lower rating individuals/businesses. So now it will be really difficult to raise money from risky businesses which is a which was a limitations of Basel II. Depositors will be more confident in the banking sector, and they will start to save more instead of spending. This will increase the capital base of the banking sector even more.


  • It has helped the banking sector be more secure due to the strict capital requirement norms.
  • Strict supervision has helped many banks not deviate from the stipulated minimum capital requirement. This practice has helped banks to save themselves from the worst scenarios.
  • Disclosure requirements have helped the banking sector be more transparent and have allowed investors from all over the world to make informed decisions.


  • Importance was lacking on the crucial capital ratios that help predict the shortfall.
  • Minimum Basel II capital requirements were not set considering the extreme outcomes. Even Basel II regulations can’t save a bank in a severe crisis. The capital reserve will be useless if a bank has invested too much in risky assets and the entire market drops. There will be a bank run.
