An understanding of the impact these changes have on the various portfolios of the bank will drive appropriate allocation of required capital to the various Banks' business lines. The following summarises the most important changes: Revision to Credit Risk Restriction of full IRB and Introduction of capital output floor Standardised Approach introduction of risk parameter floors for F-IRB Approach • The output floor restricts the bank- • Risk weights of exposures secured • AIRB is withdrawn for exposures to level internal RWAs to 72.5% of the by real estate based on loan-to-value banks; financial institutions; large standardised RWAs diversification corporates; and equities • For banks that actively manage their • Separate risk weights for investment • For high-volatility commercial real capital in coordination with business, property estate, slotting is used.

As such, the main focus of this note is on the changes proposed under Basel IV in relation to the Standardised approach for the quantification of Credit Risk, with emphasis on the changes expected to affect Cyprus Banks. Under CRD IV SA, claims in relation to specialised lending (project finance) and claims secured by residential or commercial real estate are assigned risk weights of 100%-150%, 35% and 100% respectively. In Basel IV, the SA is revised by introducing an Quantitative Impact Study: a typical In particular, specialised lending exposures increased level of granularity in these areas. Cyprus Bank and exposures secured on real estate (both corporate and retail) comprise Indeed, under Basel IV SA, claims arising To evidence the impact of the upcoming approximately 20% and 30% respectively of from specialised lending are treated changes under Basel IV on the Cyprus the overall lending, and will hence be a key differently depending on whether they arise Banks, Deloitte performed a Quantitative element when assessing the impact of the from objects and commodities (100% RW), Impact Study (QIS) the results of which are regulatory changes. or from project financing (ranging from 80- set out on page 6. 130% RW).
