Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk to earnings or asset and liability values resulting from movements in market prices. Our market risk exposures include (i) interest rate risk due to changes in the relationship between the interest rates on our assets (such as loans, receivables and investment securities) and the interest rates on our liabilities (such as debt and deposits); and (ii) foreign exchange risk related to transactions, funding, investments and earnings in currencies other than the U.S. dollar. Since December 31, 2021, there have been no material changes in market risk exposures associated with foreign exchange risk.

We analyze a variety of interest rate scenarios to inform us of the potential impacts from interest rate changes on earnings and the value of assets, liabilities and the economic value of equity. Our interest rate exposure can vary over time as a result of, among other things, the proportion of our total funding provided by variable and fixed-rate debt and deposits compared to our Card Member loans and receivables. Interest rate swaps are used from time to time to effectively convert debt issuances to variable-rate from fixed-rate, or vice versa.

Compared to December 31, 2021, the adverse impact of changes in market interest rates on our net interest income decreased, primarily due to the issuance of fixed rate liabilities. As of September 30, 2022, a hypothetical, immediate 100 basis point increase in market interest rates would have a detrimental impact of approximately $101 million on our annual net interest income. A hypothetical immediate 100 basis point decrease in market interest rates would have a smaller but still detrimental impact on our annual net interest income. This measure first projects net interest income over the following twelve-month time horizon considering forecasted business growth and anticipated future market interest rates. The detrimental impact from rate changes is then measured by instantaneously increasing or decreasing the anticipated future interest rates by 100 basis points. Our estimated repricing risk assumes that our interest-rate sensitive assets and liabilities that reprice within the twelve-month horizon generally reprice by the same magnitude as benchmark rate changes. It is further assumed that, within our interest-rate sensitive liabilities, certain deposits reprice at lower magnitudes than benchmark rate movements, and the magnitude of this repricing in turn depends on, among other factors, the direction of rate movements. These assumptions are consistent with historical deposit repricing experience in the industry and within our own portfolio. Actual changes in our net interest income will depend on many factors, and therefore may differ from our estimated risk to changes in market interest rates.
