The main objective of macroprudential measures is to strengthen banking system resilience against possible and sudden shocks. For this purpose, the CNB uses preventive measures and measures aimed at increasing banking system resilience:
- Capital conservation buffer (CCoB)
- Countercyclical capital buffer (CCyB)
- Systemic risk buffer (SRB)
- Systemically important institutions buffer (G-SII and O-SII)
- Reciprocation of measures
- Other measures and activities
Structure of capital requirements for banks
Credit institutions in Croatia are required to maintain a capital requirement of 12% or 13.5% of total risk exposure (depending on credit institution size), to which an individual capital requirement is added for each credit institution. The capital requirement structure is shown below.
The minimum own funds requirement amounts to 8% of total risk exposure. It is maintained as tier 1 (common equity tier 1 and additional tier 1) and tier 2 capital, whereby all credit institutions must, at any given moment, meet the following capital requirements:
- common equity tier 1 capital ratio of at least 4.5%;
- tier 1 capital ratio of at least 6%;
- total capital ratio of at least 8%.
The combined capital buffer is held in the form of common equity tier 1 ratio and amounts to 4% or 5.5% of total risk exposure, depending on credit institution size. It consists of capital buffers that are functions of particular types of systemic risk. They include:
- the capital conservation buffer;
- the countercyclical capital buffer;
- the systemic risk buffer; and
- the systemically important credit institutions buffer.
The total amount of the combined capital requirement of a credit institution depends on the calibration of particular instruments. The combined capital buffer consists of the capital conservation buffer of 2.5% for all credit institutions, the countercyclical capital buffer that currently amounts to 0% and the systemic risk buffer or the systemically important credit institutions buffer, depending on which is higher (currently, the systemic risk buffer with rates of 3% for larger and 1.5% for smaller credit institutions is the higher of the two)
The main liquidity standards are as follows:
- liquidity coverage ratio (LCR), which aims at improvement of the short-term liquidity positions of financial institutions by forming liquidity reserves adequate to cover possible imbalances between liquidity inflows and outflows in extremely stressed conditions during one month; and
- net stable funding ratio (NSFR), which aims at long-term, structural improvement of liquidity positions of credit institutions.
Those standards create liquidity buffers since, in stressed conditions, financial institutions will be able to temporarily decrease their level below the required regulatory minimums.
