on setting the countercyclical capital buffer rate for the Czech Republic No. IV/2021
Pursuant to Article 12o(5) of Act No. 21/1992 Coll., on Banks, as amended by Act No. 375/2015 Coll., (hereinafter referred to as the “Act on Banks”) and Article 8al(5) of Act No. 87/1995 Coll., on Credit Unions and Certain Related Measures and on the Amendment of Czech National Council Act No. 586/1992 Coll., on Income Taxes, as amended, as amended by Act No. 375/2015 Coll. (hereinafter referred to as the “Act on Credit Unions”), the Czech National Bank as a competent administrative body hereby issues the following provision of a general nature:
- Pursuant to Article 12o(3) of the Act on Banks and Article 8al(3) of the Act on Credit Unions, the countercyclical capital buffer rate for the Czech Republic shall be set at 2.00% of the total risk exposure amount pursuant to Article 92(3) of Regulation (EU) No. 575/2013 of the European Parliament and of the Council.
- Banks and credit unions shall apply the rate referred to in point I for the purposes of calculating the combined buffer requirement as from 1 January 2023.
- Pursuant to Article 12o(3) of the Act on Banks and Article 8al(3) of the Act on Credit Unions, the Czech National Bank (hereinafter referred to as the “CNB”) shall set the countercyclical capital buffer rate for the Czech Republic, taking into account the countercyclical capital buffer guide calculated pursuant to Article 12o(1) and (2) of the Act on Banks and Article 8al(1) and (2) of the Act on Credit Unions, the recommendations issued by the European Systemic Risk Board (hereinafter referred to as the “ESRB”) and indicators which may imply growth in systemic risk.
- Pursuant to Article 12o(1) of the Act on Banks, Article 8al(1) of the Act on Credit Unions and Article 9al(1) of the Capital Market Undertakings Act, the calculation of the buffer guide is based on the deviation of the credit-to-GDP ratio from its long-term trend – the credit-to-GDP gap. The credit-to-GDP ratio was 88.2% and the relevant deviation from the long-term trend -4.0 percentage points in 2021 Q2. This value pursuant to Article 12o(1) of the Act on Banks and Article 8al(1) of the Act on Credit Unions corresponds to a benchmark countercyclical capital buffer rate of 0%. The additional gap, which is based on the ESRB Recommendation (section B, Article 2) and better reflects the specificities of the Czech economy, was 4.4 percentage points in 2021 Q2 and implies a benchmark rate of 1.00%.
- In reaction to the ESRB recommendation, the CNB has repeatedly emphasised in its publications (particularly the Financial Stability Report) that it does not regard the size of the gaps referred to in paragraph 2 as a reliable guide for determining the position of the domestic economy in the financial cycle and setting the rate. The CNB prefers an approach based on a comprehensive assessment of indicators identifying growth in systemic risks under Article 12o(3) of the Act on Banks and Article 8al(3) of the Act on Credit Unions.
- The value of the financial cycle indicator increased significantly in year on year comparison in 2021 Q2, mainly as a result of increasing debt financing of residential property purchases. According to the CNB’s estimates, apartment prices were overvalued by 25%–30% in 2021 Q2. The growth rates of both the stock of, and genuinely new, loans to households for house purchase were very high and well above their long-term averages. The growth rates of loans to non-financial corporations and to households for consumption also rebounded. Overall growth in loans to the non-financial sector thus rose by more than 3 pp in 2021 Q2 and Q3, causing the cyclical risks in banks’ balance sheets to increase significantly. In line with the CNB’s current forecast, the taking on of new risks can be expected to remain above-average in the course of 2022. In view of the current economic outlook, the probability of at least partial materialisation of risks in the near future has meanwhile increased. Provisioning has returned to exceptionally low levels since the start of 2021. This may indicate that the banking sector is underestimating the accumulated risks. Cyclically lowered risk weights in the loan portfolios of banks applying the IRB approach also remain a source of systemic risk. A return of risk weights to the levels observed at the start of the last strongly expansionary phase of the financial cycle would lead to a drop in the capital ratio as a result of an increase in risk-weighted exposures (the denominator of the capital ratio). Cyclical factors are not the only factors affecting risk weights, and the estimated increase in risk weights stemming from cyclical economic developments may thus be overestimated. Nevertheless, it remains prudential to allocate part of the buffer to a possible reversal in credit characteristics accompanied by an increase in risk weights. The estimated size of unexpected credit losses along with the upper bound on the estimated cyclical increase in risk weights implies an additional capital requirement of around CZK 56 billion, which would be fully covered by a buffer rate of 2.25%. This estimate confirms the necessity to continue to create a countercyclical capital buffer.
- Based on the above assessment, and taking into account the potential overestimation of the cyclical growth in risk weights, the CNB Bank Board has decided to set the countercyclical capital buffer rate at 2.00%, which is the level necessary to ensure sufficient resilience of the financial system to these risks. In the event of a further acceleration of credit growth in the private non-financial sector, increased taking on of risks in the banking sector’s balance sheet, and rising vulnerability of the banking sector, the Bank Board is ready to increase this rate further. By contrast, should the economic situation worsen substantially and risks materialise, it is ready to gradually lower the CCyB rate or release the buffer fully in order to support banks’ ability to provide credit to non-financial corporations and households without interruption.
- Pursuant to Article 12x(1) of the Act on Bank and Article 8au(1) of the Act on Credit Unions, this provision of a general nature is announced only in a manner facilitating remote access and takes effect on the day of its publication.
This Provision shall take effect on 26 November 2021.
Financial Stability Department
This provision of a general nature was published on 26 November 2021.
 In accordance with ESRB Recommendation 2014/1 (Recommendation of the European Systemic Risk Board of 18 June 2014 on guidance for setting countercyclical buffer rates), total credit means the value of all loans provided to the private sector (non-financial corporations, households and non-profit institutions serving households) plus the volume of bonds issued by the domestic private sector. The time series of 1995 Q1–2021 Q2 and the Hodrick-Prescott filter with a smoothing parameter (λ) of 400,000 are used to calculate the long-term trend of the credit-to-GDP ratio.
 The additional gap – the expansionary credit gap – is calculated as the difference between the current ratio of bank loans to gross value added of the private non-financial sector and the minimum level of this ratio achieved in the past eight quarters.
 The methodological framework of the Czech National Bank for setting the countercyclical buffer rate is presented in the document The CNB’s approach to setting the countercyclical capital buffer.
 The annual growth rates of bank loans provided to households for house purchase and for consumption were 10.5% and 4.1% respectively in September 2021. Bank loans to non-financial corporations increased by 1.9% year on year in September 2021.
 According to the CNB’s estimate, the Czech economy entered the last strongly expansionary phase of the financial cycle in 2015 H2.
 This applies particularly to changes in banks’ models for deriving risk weights or to regulatory changes. The risk weights on the exposures of non-financial corporations were adjusted for a regulatory change of a non-cyclical nature. In Q2, this change broadened the range of corporate exposures to which the supporting factor for small and medium-sized enterprises lowering the risk weight can be applied.
 The institutions concerned shall apply a countercyclical capital buffer rate of 2.00% of the total risk exposure for the purposes of calculating the combined buffer requirement as from 1 January 2023. They shall apply a rate of 1.50% for the purposes of calculating the combined capital buffer from 1 October to 31 December 2022. They shall apply a rate of 1.00% for the purposes of calculating the combined capital buffer from 1 July 2022 to 30 September 2022. They shall apply a rate of 0.50% for the purposes of calculating the combined capital buffer until 30 June 2022.
