Since Mercer Capital’s most recently published article on core deposit trends in September 2022, the banking industry has faced abysmal deal activity. The scarcity of transactions can largely be blamed on unfavorable deal math due to required balance sheet marks on underwater securities and loan portfolios. Compressed P/E ratios, credit quality concerns (especially for commercial real estate portfolios), regulatory headwinds, pressures on profitability, and uncertainty in the wake of several bank failures earlier in 2023, have also contributed to a quiet year from an M&A perspective. Although deal activity has been slow, we have seen an obvious uptick in core deposit intangible values relative to this time last year.
On July 26, 2023, the Federal Reserve increased the target federal funds rate by 25 basis points, capping off a collective increase of 100 basis points year-to-date and 525 basis points since March 2022. While many factors are pertinent to analyzing a deposit base, a significant driver of value is market interest rates.
Using data compiled by S&P Capital IQ Pro, we analyzed trends in core deposit intangible (CDI) assets recorded in whole bank acquisitions completed from 2000 through mid-August 2023. CDI values represent the value of the depository customer relationships obtained in a bank acquisition. CDI values are driven by many factors, including the “stickiness” of a customer base, the types of deposit accounts assumed, the level of noninterest income generated, and the cost of the acquired deposit base compared to alternative sources of funding. For our analysis of industry trends in CDI values, we relied on S&P Capital IQ Pro’s definition of core deposits.1
In analyzing core deposit intangible assets for individual acquisitions, however, a more detailed analysis of the deposit base would consider the relative stability of various account types. In general, CDI assets derive most of their value from lower-cost demand deposit accounts, while often significantly less (if not zero) value is ascribed to more rate-sensitive time deposits and public funds. Non-retail funding sources such as listing service or brokered deposits are excluded from core deposits when determining the value of a CDI.
Figure 2, summarizes the trend in CDI values since the start of the 2008 recession, compared with rates on 5-year FHLB advances. Over the post-recession period, CDI values have largely followed the general trend in interest rates—as alternative funding became more costly in 2017 and 2018, CDI values generally ticked up as well, relative to post-recession average levels. Throughout 2019, CDI values exhibited a declining trend in light of yield curve inversion and Fed cuts to the target federal funds rate during the back half of 2019. This trend accelerated in March 2020 when rates were effectively cut to zero.
CDI values have increased meaningfully in the past few quarters (with an average CDI value of 171 and 339 basis points for the first and second quarters of 2023, respectively). This compares to 155 basis points for all of 2022 and 64 basis points for all of 2021. Recent values are above the post-recession average of 1.39%, and on par with longer-term historical levels which averaged closer to 2.5% to 3.0% in the early 2000’s.
As shown in Figure 2, reported CDI values have followed the general trend of the increase in FHLB rates. However, the averages from 2023 should be taken with a grain of salt. The chart is provided to illustrate the general directional trend in value as opposed to being predictive of specific indications of CDI value due to the following reasons:
Eleven deals were announced in July and the first half of August, and three of those deals provided either investor presentations or earnings calls containing CDI estimates. These CDI estimates ranged from 3.6% to 4.0%, which is in line with the numbers we have observed in our valuation analyses. We expect CDI values to continue rising in concert with market interest rates. However, market interest rates are not the only driver of CDI value, and there are some potentially mitigating factors to CDI values in the near term.
Core deposit intangible assets are related to, but not identical to, deposit premiums paid in acquisitions. While CDI assets are an intangible asset recorded in acquisitions to capture the value of the customer relationships the deposits represent, deposit premiums paid are a function of the purchase price of an acquisition. Deposit premiums in whole bank acquisitions are computed based on the excess of the purchase price over the target’s tangible book value, as a percentage of the core deposit base. While deposit premiums often capture the value to the acquirer of assuming the established funding source of the core deposit base (that is, the value of the deposit franchise), the purchase price also reflects factors unrelated to the deposit base, such as the quality of the acquired loan portfolio, unique synergy opportunities anticipated by the acquirer, etc. As shown in Figure 7, deposit premiums paid in whole bank acquisitions have shown more volatility than CDI values. Deposit premiums in the range of 6% to 10% remain well below the pre-Great Recession levels when premiums for whole bank acquisitions averaged closer to 20%.
Additional factors may influence the purchase price to an extent that the calculated deposit premium doesn’t necessarily bear a strong relationship to the value of the core deposit base to the acquirer. This influence is often less relevant in branch transactions where the deposit base is the primary driver of the transaction and the relationship between the purchase price and the deposit base is more direct. Figure 8 presents deposit premiums paid in whole bank acquisitions as compared to premiums paid in branch transactions.
Deposit premiums paid in branch transactions have generally been less volatile than tangible book value premiums paid in whole bank acquisitions. Only four branch transactions with reported premium data have occurred year-to-date in 2023. For those transactions, the deposit premiums ranged from 2.0% to 6.0%. The lack of branch transactions, though, is indicative of their value. With high short-term funding costs and tight liquidity, few banks are willing to part with stable, low cost core deposits.
Based on the data for acquisitions for which core deposit intangible detail was reported, a majority of banks selected a ten-year amortization term for the CDI values booked. Less than 10% of transactions for which data was available selected amortization terms longer than ten years. Amortization methods were somewhat more varied, but an accelerated amortization method was selected in approximately half of these transactions.
