Bank of New York Mellon Corp

Our diversified business activities include processing securities, accepting deposits, investing in securities, lending, raising money as needed to fund assets and other transactions. The market risks from these activities include interest rate risk and foreign exchange risk. Our primary market risk is exposure to movements in U.S. dollar interest rates and certain

BNY 41 foreign currency interest rates. We actively manage interest rate sensitivity and use earnings simulation and discounted cash flow models to identify interest rate exposures.

An earnings simulation model is the primary tool used to assess changes in pre-tax net interest income between a baseline scenario and hypothetical interest rate scenarios. Interest rate sensitivity is quantified by calculating the change in pre-tax net interest income between the scenarios over a 12-month measurement period.

The baseline scenario incorporates the market’s forward rate expectations and management’s assumptions regarding client deposit rates, credit spreads, changes in the prepayment behavior of loans and securities and the impact of derivative financial instruments used for interest rate risk management purposes as of each respective quarter-end. These assumptions have been developed through a combination of historical analysis and future expected pricing behavior and are inherently uncertain. Actual results may differ materially from projected results due to timing, magnitude and frequency of interest rate changes, and changes in market conditions and management’s strategies, among other factors. Client deposit levels and mix are key assumptions impacting net interest income in the baseline as well as the hypothetical interest rate scenarios. The earnings simulation model assumes static deposit levels and mix, and it also assumes that no management actions will be taken to mitigate the effects of interest rate changes. Typically, the baseline scenario uses the average deposit balances of the quarter.

In the table below, we use the earnings simulation model to assess the impact of various hypothetical interest rate scenarios compared to the baseline scenario. In each of the scenarios, all currencies’ interest rates are instantaneously shifted higher or lower at the start of the forecast. Long-term interest rates are defined as all tenors equal to or greater than three years and short-term interest rates are defined as all tenors equal to or less than three months. Interim term points are interpolated where applicable. The impact of interest rate shifts may not be linear. The results of this earnings simulation should therefore not be extrapolated for more severe interest rate scenarios than those presented in the table below.

The following table shows net interest income sensitivity for BNY.

At Sept. 30, 2024, the changes in the impacts of a 100 basis points upward or downward shift in rates on net interest income compared with June 30, 2024 were primarily driven by an increase in fixed-rate assets and slightly lower deposit rate sensitivities.

While the net interest income sensitivity scenario calculations assume static deposit balances to facilitate consistent period-over-period comparisons, net interest income is impacted by changes in deposit balances and interest rate trajectory. Noninterest-bearing deposits are particularly sensitive to changes in short-term rates.

To illustrate the net interest income sensitivity to noninterest-bearing deposits, we estimate that a $5 billion instantaneous reduction/increase in U.S. dollar-denominated noninterest-bearing deposits would reduce/increase the net interest income sensitivity results in the up 100 basis point rate shock scenario in the table above by approximately $240 million, and in the down 100 basis point rate shock scenario by approximately $140 million. The impact would be smaller if the reduction/increase was assumed to be a mixture of interest-bearing and noninterest-bearing deposits.

Additionally, during periods of low short-term interest rates, money market mutual fund fees and other similar fees are typically waived to protect investors from negative returns.
