Pääomavaatimusjärjestelmät

Pääomavaatimusjärjestelmät, often translated as capital requirement systems, refer to the regulatory frameworks that mandate financial institutions, particularly banks, to hold a minimum amount of capital against their assets. These systems are designed to ensure the solvency and stability of the financial sector by providing a buffer against potential losses. The core principle is that institutions must have sufficient capital to absorb unexpected shocks without failing.

The most prominent example of a capital requirement system is Basel Accords, developed by the Basel Committee on Banking Supervision. These accords, particularly Basel III, set international standards for capital adequacy. They categorize risk into credit risk, market risk, and operational risk, and require banks to hold capital commensurate with the level of risk in their portfolios.

There are generally two main approaches to calculating capital requirements: the standardized approach and internal models approach. The standardized approach relies on regulator-defined risk weights for different asset classes. The internal models approach allows banks to use their own sophisticated risk measurement models, subject to supervisory approval, to determine their capital needs.

The ultimate goal of these systems is to protect depositors and the broader economy from financial crises. By ensuring banks are well-capitalized, regulators aim to reduce the likelihood of bank failures and the need for taxpayer-funded bailouts. Ongoing reviews and updates to these systems, such as Basel IV, reflect the evolving nature of financial markets and the continuous effort to enhance financial stability.
