The market risk encompasses current and prospective impact on earnings or capital, arising from changes in the value of the Group’s portfolio due to adverse market movement (prices).
The interest rate risk arising from Banking Book activities (IRRBB) encompasses current or prospective impact to both the earnings and the economic value of the Group’s portfolio arising from adverse movements in interest rates that affect interest rate sensitive instruments. The risk includes gap risk, basis risk and option risk.
The framework of market risk and interest rate risk management and its control are defined on a centralized basis with the use of the same concepts and metrics which are used in all the entities of the BCP Group.
The main measure used by the Group to evaluate market risks is the parametric VaR (Value at Risk) model – an expected loss that may arise on the portfolio over a specified period (holding period) with a required probability (confidence level) due to an adverse market movement. The market risk measurement is carried out daily, both on an individual basis for each of the areas responsible for risk taking and risk management, and in consolidated terms for Global Bank, Banking Book and Trading Book considering the effect of the diversification that exists between the portfolios.
Within the current market environment, the Group continued to act very prudently. The strong market volatility in connection with the global COVID-19 pandemic and Monetary Policy Council’s (MPC’s) series of decisions to increase interest rates in Poland resulted in increase of the Group’s market and interest rate risk.
In 2021, the VaR for the Group that is jointly Trading Book and Banking Book, increased due to market volatility and in 4Q2021 breached the limits in place. The VaR limits were not breached in Trading Book. All excesses of market risk limits are always reported, documented, and ratified at the proper competence level.
In 2021, open positions included just interest-rate instruments and FX risk instruments. The VaR indicators for the Group remained on average at the level of PLN161.7mn (63 per cent of the limit) and PLN391.3mn (150 per cent of the limit) as of the end of December 2021. However, in 2021, the VaR limits were very conservative – set for Global Bank at no more than 2.6 per cent and for Trading Book at 0.31 per cent of Own Funds). FX open position (Intraday as well as Overnight) remained below 2 per cent of The Own Funds and well below the maximum limits in place.
Apart from daily measurement at the level of each book and market risk area, the VaR model is mainly applicable and analysed at the Trading Book level, where the policy intention is to trade positions on the regular basis (mostly daily). On contrary, following the supervisory guidelines, the interest rate risk in Banking Book is additionally covered by both earnings-based and economic value measures, by measuring:
- the impact on the net interest income over a time horizon of next 12 months resulting from one-off interest rate shock of upward/downward yield curve shift by 100 basis points,
- the impact on the economic value of equity (EVE) resulting from different upward/downward basis points shocks, including scenarios defined by the supervisor (standard, supervisory test assuming sudden parallel +/-200 basis points shift of the yield curve as well supervisory outlier test – SOT with set of six interest rate risk stress scenarios).
Exposure to interest rate risk in the Banking Book are primarily generated by the differences in repricing dates of assets and liabilities as well as its reference indexes, if contractually existing. It is specifically affected by the unbalance between assets and liabilities that have fixed rate, especially by the liabilities which cannot have interest rate lower than 0. Consequently, the level of sensitivity to interest rate changes is influenced by the level of interest rates taken as a reference. Additionally, due to specificity of the polish legal system, the interest rate of credits is limited (it cannot exceed two times Reference Rate of the National Bank of Poland increased by 7 percentage points). In situations of decreasing interest rates, the impact on Net Interest Income is negative and depends on the share of the loan portfolio that is affected by the new maximum rate. On the other hand, assumptions regarding the timing and size of deposits repricing are also very important when assessing the interest rate sensitivity and risk.
Considering the increase of interest rates that occurred in the 4th quarter 2021, the results of the IRRBB measurement as of the end of December 2021 indicate that the Group is now in a more balanced situation regarding the scenario of a decline or increase in interest rates. The supervisory outlier stress tests result as of December 2021 show that even under the most severe outlier test scenario, the decline of EVE for Banking Book is far below supervisory limit of 15 per cent of Tier 1. Similarly, decline of EVE under standard scenario of sudden parallel +/-200 basis points shift of the yield curve also stayed far below supervisory maximum of 20 per cent of Own Funds.
The results of sensitivity of NII for the next 12 months after 31st December 2021 and for position in Polish Zloty in Banking Book are carried out under the following assumptions:
- static balance sheet structure as of that reference date (no change during the following 12 months),
- reference level of net interest income assuming that all assets and liabilities with variable interest rate already reflect market interest rates levels as of 31st December 2021 (for example, the NBP Reference rate at the end of 2021 was set at 1.75 per cent),
- application of a parallel move of 100 bps in the yield curve up and down is an additional shock to all market interest rates levels as of 31st December 2021 and is set at the repricing date of the assets and liabilities that happens during the 12 following months.
In a scenario of parallel decrease of interest rates by 100bp, the results are negative and equal to PLN-162mn or -6.0 per cent of the Group’s NII reference level; In a scenario of parallel increase of interest rates by 100bp, the results are positive and equal to PLN160mn or +5.9 per cent of the Group’s NII reference level. The level of asymmetry that existed in past reporting dates is now lower as interest rates were meaningfully above 0 per cent on 31st December 2021 and the leverage impact of the maximum interest rate is now less strong than in previous years due to changes in the structure of portfolio and pricing of loans.
