At first pass, the expansion in the NIMs is less than might be expected; however, there are always a number of factors in bank balance sheets that will impact the NIM, including:
- Loan Floors. Many Libor- and prime-based commercial loans had floors that required 100-150bps of hikes before the floors were “out-of-the-money.”
- Competition. Intense competition for loans in an environment in which bonds yielded very little resulted in pressure in the margin over a base rate as bank and non-bank lenders accepted lower margins in order to make loans.
- Asset Mix. Community banks located in rural and semi-rural areas tend to have low loan-to-deposit ratios and, therefore, have not benefited as much as peers located in and around MSAs that are “loaned-up.” Nonetheless, net loans as a percentage of assets among community banks increased by an average of 15bps each quarter since year-end 2016 while bond portfolios declined.
- Loan Mix. Community banks tend to have somewhat more of their loan portfolios allocated to residential mortgages and CRE than regional banks. As a result, it will take much longer for these mostly fixed-rate assets to reprice than Libor-based C&I portfolios.
- Deposit COF. In recent quarters the marginal cost of funds (“COF”) has become expensive as depositors who came to accept being paid essentially nothing for their money began to demand more competitive rates once the Fed Funds rate approached 2%.
- Deposit Mix. In addition to depositors demanding higher rates, a mix shift from non-interest bearing and very low-yielding transaction accounts into higher paying money markets and time deposits has pushed the COF higher, too, in recent quarters.
Fed to Cut Rates?
Recent incremental pressure on NIMs notwithstanding, community banks’ balance sheets were poised to take advantage of rising rates the past several years. The outperformance of bank stocks beginning in November 2016 reflected several factors, including an economic and regulatory backdrop that would allow the Fed to raise rates further and faster, and thereby support NIM expansion.
The underperformance of bank stocks since last fall reflects investor concern that this tailwind is ending in addition to more general concerns about what a possible economic slowdown implies for credit costs. Telltale signs include the inversion of the Treasury yield curve and yields on the two-year and five-year Treasuries that, as of the date of the drafting of this article, are below the low-end of the Fed Funds target range.
Also, the spot and forward curves for 30-day Libor imply the Fed will cut the Funds target rate and other short-term policy rates one or two times by early 2020 (or stated differently, the December rate hike was a mistake).
The Federal Funds rate, the predominant influence on short-term interest rates, has remained unchanged since year-end 2018 at a target range of 2.25%–2.50% due to concerns about lower inflation figures and what they may forewarn about future economic growth as reflected in falling U.S. Treasury yields. The FOMC reiterated its wait-and-see approach on May 1. However, the sand appears to be shifting beneath the Fed’s feet.
The Wall Street Journal’s most recent Economic Forecasting Survey revealed an increasing belief that the Fed’s next move will be to cut rates. 51% of respondents said that a rate cut would be the next move, up from 44% in April. 25.5% replied that the next rate raise would occur in 2020 or later. Fed officials have maintained their stance that a rate move in either direction will not occur soon.
The Importance of Deposits and Next Steps
As deposit costs initially lagged, but more recently moved with short-term interest rate hikes, the composition of a bank’s deposit base and funding structure has become increasingly important. As shown in Figure 4, the percentage of banks experiencing a rising cost of interest bearing deposits has steadily increased. Total funding costs have nearly doubled since year-end 2016 as depositors have reoriented funds toward accounts offering higher rates. Banks searching for funding either must engage in intense deposit competition or tap into higher-cost sources such as wholesale funding.
Going forward community banks may face a modest reduction in NIMs because the yield curve is flat and the cost of incremental funding is expensive. Some community banks will choose to slow loan growth in order to protect margins; others will accept a lower margin. The predicament demonstrates yet again why deposit franchises are a key consideration for acquirers as banks with low cost deposit franchises and excess liquidity are particularly attractive in the current market.
