What Is Tier 2 Capital?
The term tier 2 capital refers to one of the components of a bank's required reserves. Tier 2 is designated as the second or supplementary layer of a bank's capital and is composed of items such as revaluation reserves, hybrid instruments, and subordinated term debt. It is considered less secure than Tier 1 capital—the other form of a bank's capital—because it's more difficult to liquidate. In the United States, the overall capital requirement is partially based on the weighted risk of a bank's assets.

Understanding Tier 2 Capital
Bank capital requirements were designated as part of the international Basel Accords. This set of recommendations was developed by the Basel Committee on Bank Supervision over a number of years dating back to the 1980s. According to the regulations, banks must maintain a certain amount of cash and/or other forms of liquid assets on hand in order to meet their obligations. No more than 25% of a bank's capital requirements can be comprised of Tier 2 capital.
Bank capital is divided into two layers—Tier 1 or core capital and Tier 2 or supplementary capital. A bank's capital ratio is calculated by dividing its capital by its total risk-based assets. The minimum capital ratio reserve requirement for a bank is set at 8%—6% of which must be provided by Tier 1 capital. The remaining must be Tier 2 capital. Along with Tier 1 capital, it provides a bank with a financial cushion in case it needs to liquidate its assets.
There are four components of Tier 2 capital. These include:
- Revaluation Reserves: These are reserves created by the revaluation of an asset. A typical revaluation reserve is a building owned by a bank. Over time, the value of the real estate asset tends to increase and can thus be revalued.
- General Provisions: This category consists of losses that a bank may have of an as yet undetermined amount including from loans. The total general provision amount allowed is 1.25% of the bank's risk-weighted assets (RWA).
- Hybrid Capital Instruments: This type of capital is a mixture of both debt and equity instruments. Preferred stock is an example of a hybrid instrument. A bank may include hybrid instruments in its Tier 2 capital as long as the assets are sufficiently similar to equity so losses can be taken on the face value of the instrument without triggering the liquidation of the bank.
- Subordinated Debt: Debt is subordinated in regard to ordinary bank depositors and other loans and securities that constitute higher-ranking senior debt. The minimum original term of this debt is five years or more.
Tier 2 capital is split into upper and lower levels. Upper-level Tier 2 capital consists of securities that are perpetual—meaning they have no maturity date—revaluation reserves, and fixed asset investments. Lower-level Tier 2 capital consists of subordinated debt and is generally inexpensive for a bank to issue.
- Tier 2 capital is the second layer of capital that a bank must keep as part of its required reserves.
- This tier is comprised of revaluation reserves, general provisions, subordinated term debt, and hybrid capital instruments.
- There are two levels of Tier 2 capital—upper level and lower level capital.
- Tier 2 capital is subordinate to Tier 1 capital and is considered riskier as it is more difficult to calculate if a bank needs to liquidate it.
Undisclosed reserves may be counted as part of a bank's Tier 2 capital in certain countries. These reserves are profits a bank earns that don't appear on publicly-available documents such as a bank's balance sheet. Despite not being disclosed, most banks still consider these reserves to be real assets. Regulatory authorities in some countries recognize their banks' undisclosed reserves as part of Tier 2 capital. Most countries, including the United States, do not allow this kind of capital to be used to legitimately meet reserve requirements.

Tier 2 Capital vs. Tier 1 Capital
As mentioned above, a bank's capital reserves are divided into tiers. Unlike Tier 2 capital, Tier 1 capital is a bank's core capital or the primary source of funding for a bank. As such, it consists of almost all of an institution's funds including all of its disclosed reserves and any equity capital like common stock. This capital helps a bank absorb any losses so it can continue its day-to-day operations. Because this level is composed of a bank's core capital, Tier 1 is a very good indicator of its financial health. This tier is considered more reliable than Tier 2 capital. That's because the capital is much easier to calculate accurately. The assets that fall into this category are also much easier to liquidate.
