PNC utilizes sensitivities of NII and EVE to a set of interest rate scenarios to identify and measure its short-term and long-term structural interest rate risks.

NII sensitivity results for the fourth quarters of 2024 and 2023 follow:

Table 35: Net Interest Income Sensitivity Analysis

(a)The effect on NII in the first year from a 100 basis point instantaneous increase or decrease is not materially different from the 200 basis point scenarios as disclosed above.

When forecasting NII, we make certain key assumptions that can materially impact the resulting sensitivities, including the following:

Future Balance Sheet Composition: Our balance sheet composition is dynamic and based on our forecasted expectations. As of the fourth quarter 2024, the projected balance sheet composition by the end of year one is generally consistent with the spot composition at December 31, 2024.

Balance Sheet Forecast: Our balance sheet forecast is based on various assumptions that include key interest rate risk aspects such as loan and deposit growth, as well as mix, and is consistent with our guidance.

Deposit Betas: Deposit pricing changes are primarily driven by changes in the Federal Funds rate. PNC’s deposit beta was 47% for

December 2024. We define deposit beta as the change in deposit rate paid on total interest-bearing deposits divided by the change in

the upper level of the average stated Federal Funds rate range since August 2024, the start of the current easing rate cycle. For rate

sensitivity purposes, PNC assumes the cumulative deposit beta will decrease from the current level. Prior to the beginning of the easing cycle, PNC’s beta calculation represented the change in deposit rate paid on interest-bearing non-maturity deposits divided by the change in the upper level of the stated Federal Funds rate since the first quarter of 2022, the start of the rising rate cycle. For interest rate risk modeling, PNC uses dynamic beta models to adjust assumed repricing sensitivity depending on market rate levels as

The dynamic beta assumptions reflect historical experience as well as future expectations, and are periodically updated to reflect the current view of future expectations. Actual deposit rates paid may differ from modeled projections due to variables such as competition for deposits and customer behavior.

Asset Prepayments: PNC includes prepayment assumptions for both loan and investment portfolios. Mortgage and Home Equity portfolios utilize an industry standard model to drive estimated prepayments that increase in lower rate environments. Commercial and other consumer loan portfolios assume static constant prepayment rates that are consistent across rate scenarios, as those portfolios historically do not exhibit significantly different prepayment behaviors based upon the level of market rates.

Impact of Derivatives: As part of our risk management strategy, PNC uses interest rate derivatives, some of which are forward starting, to hedge floating rate commercial loans. PNC had $50.5 billion in active and forward starting receive fix / pay float swaps as of December 31, 2024, with a weighted average duration of 2.4 years and an average fixed rate of 3.45%. As of December 31, 2024 PNC also had collars in place, reflecting $12.5 billion of caps and $12.5 billion of floors, that are used to hedge these commercial loans. Additionally, PNC utilizes receive fix / pay float swaps as a means of hedging fixed rate debt, as well as pay fix / receive float swaps as a means of hedging the investment securities portfolio. See Note 15 Financial Derivatives for additional information on how we use derivatives to hedge these financial instruments.
