averaged all of 77 basis points (0.77%) between 2010 and 2022, peaked at 2.50% in late 2018. It’s surprising to me how long rates were depressed in the aftermath of the Great Recession. Another headwind for bank profitability in the recent past is how quickly cost of fund rose relative to portfolio yields. One major cause of this deterioration was that bond durations extended dramatically in 2022-2023, and very few purchases occurred during the big run-up in market yields. The spread between portfolios and the related cost-of-carry shrank by well over 100 basis points between 2020 and 2024. VIDI … Nonetheless, portfolio income has slowly made a comeback, and it’s hoped that some staying power has been built into the current structures. Average durations remain elevated (still over four years), and mild rate shock tests (+/- 100 bps) indicate portfolio cash flows should remain reasonably stable. These are metrics that seem to be built for a slow-to-fall rate environment, which is precisely what the Federal Reserve, economists and market indicators are projecting for 2026. Another point of note is that sector weightings look pretty similar to 2018. At both measuring periods, treasuries/agencies were around 15% of the total, all mortgage-related products were around 50% and municipals were about 22%. What is interesting is that the top quartile seven years ago had a full 41% muni allocation, and today it’s only about 14%. The main culprit, as has been well-documented, is the tax relief that became law in 2018 and reduced tax-equivalent yields for many bank investors. VICI I am speaking with some conjecture here, but the near-term prospects for bond performance are pretty solid. Everyone, including the Fed, agrees that rates are somewhat restrictive, and Chairman Jerome Powell is in no particular hurry to aggressively drop them, even if one or two cuts are still in the 2025 numbers. That would give community banks some more time to layer in bonds at levels they’ll be glad to own later. More inference is that the cost of funds, even if the Fed remains patient, should continue to decline. The second quarter of 2025 was the fourth straight period of declining deposit costs for community banks, and coupled with the expected continued improvement in portfolio returns, net interest margins for the rest of the year look to be attractive. To conclude: The backdrop of 3% portfolio yields seems to bode well for “faster, higher, stronger” community bank performance.
