Decay rates in banking

understand and support your institution-specific assumptions for decay rates, their deposit base (bank-branch-product-customer-relationship-demographics) 

Decay Rates – All OCC Institutions • Decay assumptions, a measure of average life that shows the percentage of deposits that “run-off” or move out of a type of deposit, were collected for six different deposit categories. • In the chart above, for MMDAs, 1,149 banks reported decay rates over the full range of possibilities (0% Where the historical relationship between bank’s deposit rates and balances can be used as an indicator to estimate decay rates. Assuming, if a bank pays an above market rate, it will attract more deposits but at a thinner margin where as if it pays below market rate, it will widen margin at the expense of shorter life. Deposit decay rates should be calculated by tracking a representative sample of accounts over a period of time that covers at least one interest rate cycle. Such volatility studies have been used by banks for many years to determine effective maturity assumptions that are then employed in present value analysis to calculate core deposit values If decay rates are not included, it will result in longer deposit cash flows, an unrealistic market valuation of deposits and, ultimately, an understatement of interest rate risk in a rising rate environment. Credit unions should check their ALM models to make sure reasonable decay rates are appropriately applied and coincide with key Deposit Decay Rates CFO at a bank ( $247M USA ) This is a spreadsheet I developed to measure deposit decay rates and liability sensitivity of non-maturity deposits.

Where the historical relationship between bank’s deposit rates and balances can be used as an indicator to estimate decay rates. Assuming, if a bank pays an above market rate, it will attract more deposits but at a thinner margin where as if it pays below market rate, it will widen margin at the expense of shorter life.

By adjusting the deposit mix to pre-recession levels, using the same 200 bps increase in interest rates, you’d see your EAR drop to a positive exposure of 1.8 percent. Similarly, changing account balance assumptions to assume a decline in non–interest bearing deposits or changing deposit decay and beta-adjusted gap assumptions could easily take a positive EAR result and make it negative. • Decay Rate – estimates the amount of existing non-maturity deposits that will run off over time. • Weighted Average Life – estimates the average effective maturity of the deposits. Driver Rate – represents the rate, or rates, which drive the re-pricing character-istics of assets and liabilities.

If you decay a savings account over a 60-month period, you make the assumption that the savings account will have a 60-month maximum life. The normal range for decay is 24 months for sensitive deposits and 84 months for more static accounts. Deposit Decay Rate Analysis, Beta and EVE (Economic Value of Equity) are all closely related concepts for determining your bank long term interest rate risk. Non Maturity Deposit Decay Rate is the single biggest factor in your EVE profile. Join Howard Lothrop for this quick training discussion. Deposit decay rates should be calculated by tracking a representative sample of accounts over a period of time that covers at least one interest rate cycle. Such volatility studies have been used by banks for many years to determine effective maturity assumptions that are then employed in present value analysis to calculate core deposit values for deposit purchases, branch acquisitions, and bank acquisitions. If you've read my NMDA deposit study materials you know I'm a big believer in thinking "average life" anytime someone says "decay rate". To me, average life is just a simpler concept where we already have a good frame of reference.

When a bank finally elects to change deposit rates, it often will do so to a lesser extent than the prevailing change in market interest rates and often to different degrees depending on whether the rate change is upward or downward. By adjusting the deposit mix to pre-recession levels, using the same 200 bps increase in interest rates, you’d see your EAR drop to a positive exposure of 1.8 percent.
