What Is the Minimum Capital Adequacy Ratio Under Basel III in 2022

Basel III is the set of regulations developed and implemented by the Bank of International Standards to maintain and promote the stability of the International Banking and Financial system. The system is designed to minimize the risk and possible outcomes of risky decisions that Banks take to achieve certain goals that can potentially affect the economy.

Basel III was a refined form of Basel I and Basel II, it was implemented after the 2008 Global Financial Crisis, and its main purpose was to strengthen the Bank's ability to face financial stress and its shocks afterward!

This short detail would not be enough, and you can continue to learn about the minimum capital adequacy ratio under Basel III in detail here!

Adequacy Ratio as per Basel III:

According to Basel III, capital adequacy measures the Bank's capital and ability to withstand financial stress against risk-adjusted assets. It improves banks' resilience to severe financial crises; it provides a threshold and creates resistance against unprecedented financial upsets and worldwide crises like a financial recession.

It helps the Bank maintain sufficient capital to survive and resist a series of financial hardships in the economy. It came into effect after the 2008 Recession, and all the member countries implemented it in their respective financial institutions.

Minimum Capital Requirements According to Basel III:

Capital adequacy is the sum of category 1 capital and category 2 capital and then divided the sum (tier1+tier2) with the RWA of the Bank. The tier 1 and tier 2 capital works together to strengthen the Bank during a crisis. The function of these capitals is:

Tier 1:

Category 1 capital comprises the Bank's principal capital, which further consists of Bank equity capital and revealed reserves of the Bank. This form of capital leverages or resists the losses without closing any banking operations.

Tier 2:

Category 2 capital, on the other hand, is used to take losses in liquidation. The minimum capital adequacy ratio, incorporating tier1, tier 2 capitals, and extra capital to provide a buffer for financial security, should be comprised of a minimum of 10.5%; this percentage implies the risk-weighted assets, which sums to the reserves requirement total of 8% and 2.5% funds in conversion buffer. This buffer builds banks' capital capability to use during financial uncertainty.

Example:

For better understanding, let's consider that Bank A possesses a reserve of five million dollars in category 1 capital and three million dollars in category 2 capital. Now Bank A provides a loan of five million dollars to X Corporation with a risk factor of 25% and a fifty million dollar loan to Y Corporation with a risk factor of 55%.

• Bank A RWAs of 28.75 million dollars (5 * 0.25 + 50 * 0.55).
• Bank A also possesses 8 million dollars capital ( 5 million dollars + 3 million dollars)
• Total adequacy ratio 27.83% calculated as (8 /28.75 * 100)
• Category 1 ratio stays at 17.39% and is calculated as (5 /28.75 * 100).

As a result, Bank A has successfully attained the CAR (capital adequacy ratio) as per Basel III.

Increase in Minimum Capital Requirements:

The Basel III accord also increased the minimum capital requirement of the banks. It increased from 2% in Basel II to 4.5% in common equity and as a percentage of the Bank's risk-weighted assets.

Apart from this, a 2.5% extra buffer capital requirement makes it 7% to comply with Basel III. The extra buffer is used to cater to the financial stress, but using the buffer may lead to financial constraints while paying dividends.

Minimum Leverage Ratio under Basel III:

Apart from the Minimal Capital Adequacy ratio, the other major change in Basel III is the limiting of excessive leverage present in the banking sector. The bank leverage is the sum proportion of capital and exposure measures.

The Basel body decides to change these leverage ratios; according to them, a plain leverage framework is critical and supportive of the risk-based assessment and framework. They also view that leverage should adequately monitor continual balance sheet sources or the origin of bank leverage.

The Basel committee also does the legislation to limit the operations of Global systemically important banks (G-SIBs) or systemically important financial institutions (SIFIs). Whatever comes under these categories of banks is termed too big to fail. These banks are tested intensively and under excess regulations in a country like the USA.

Liquidity Requirements:

The Basel III accord introduces two liquidity ratios: the liquidity coverage ratio and the net stable funding ratio. These two are defined as:

Liquidity Coverage Ratio:

The liquidity coverage ratio ensures that the Bank holds sufficient highly liquid assets that can bear a 30-day stressed funding scenario defined by the supervisors. This mandate was introduced in 2015.

Net Stable Funding Ratio:

The net stable funding ratio NSFR ensures that banks must maintain stable funding above the required amount for at least one year to bear any extended stress.

Other Countercyclical Measures:

The tier 1 capital requirement for the Bank was also increased to 6% from 4% in Basel II. Basel III implies 6% includes 4.5% of the common equity Tier 1 and 1.5% additional tier 1 capital.

Effects of Basel III:

The main objective of Basel III is to lead a safer financial system while minimizing its effect the future economic growth. These principles may affect investors with diverse portfolios; however, bond and stock investors are much safer due to the market's stability.

Basel III also enables the investors to understand the financial sector moving forward by formulating the macroeconomics opinion on the stability of the global financial system and world economy.

Final Thoughts:

The main purpose of the Basel III Accord is to take preventive measures for Bank or other financial institutions in case of financial stress or builds the capacity to bear the Global financial crisis.

The minimum Adequacy ratio is one of the many factors presented in Basel III. For now, the minimum capital adequacy ratio in 2022 is 10.5%. If implemented properly, it will lead to better sustainable economic growth.
