TrustCo Bank Corp NY recently released its Q1 2024 earnings transcript [Source: TrustCo Bank Corp NY Earnings Transcript], a document filled with the usual dry financial figures and cautious pronouncements. Analysts have dissected the numbers, scrutinizing net interest margin trends and loan growth. But amidst the technical jargon, a subtle yet significant pattern has emerged, one that seems to have slipped past the eagle eyes of Wall Street. This pattern reveals a fascinating insight into TrustCo's deposit strategy, a strategy that could position them to capitalize on a potential shift in the interest rate environment.

The transcript reveals a peculiar preference among TrustCo's customers for shorter-term certificates of deposit (CDs). When offered a choice between a 4.9% CD for three months and a 4.75% CD for six to nine months, the vast majority opt for the higher rate, three-month option, even though the rate differential is marginal. This 'three-month shuffle,' as we might call it, speaks volumes about the mindset of TrustCo's customer base.

Firstly, it suggests a degree of uncertainty and caution among depositors. In a climate of fluctuating interest rates, customers are hesitant to lock in their funds for extended periods, even for a slightly higher yield. They prefer the flexibility of shorter-term CDs, allowing them to reassess their options as the interest rate landscape evolves.

Secondly, the three-month shuffle plays beautifully into TrustCo's strategic advantage as a portfolio lender. With a significant portion of their deposit base rolling over every three months, they possess remarkable agility in adjusting deposit rates to align with market conditions. This dynamic pricing capability, combined with their conservative lending practices, allows them to weather interest rate fluctuations better than many of their peers who rely on longer-term, fixed-rate funding.

Consider the implications if interest rates indeed decline later in 2024, as some economists predict. TrustCo will be ideally positioned to rapidly reduce deposit costs as those three-month CDs mature. Their cost of funds will decline swiftly, while their asset yields, primarily anchored by their portfolio of long-term, fixed-rate mortgages, will remain relatively stable. This scenario could translate into a significant expansion of their net interest margin, boosting profitability and potentially outpacing the performance of other banks burdened by higher-cost, longer-term funding.

Potential Impact of Interest Rate Decline

To quantify the potential impact, let's consider a hypothetical scenario where the Federal Reserve cuts rates by 50 basis points over the next two quarters. Assuming a 70% rollover rate on maturing CDs and a 50% pass-through of rate cuts to new CD offerings, TrustCo could potentially reduce their cost of interest-bearing liabilities by approximately 18 basis points.

Now, while their asset yields might also experience some compression, the impact would be considerably less pronounced due to the long-term, fixed-rate nature of their loan portfolio. We could conservatively estimate a 10 basis point decline in the yield on earning assets. The net effect? An 8 basis point expansion in net interest margin. While seemingly small, this improvement could translate into millions of dollars in additional net interest income.

This analysis highlights the power of the three-month shuffle. It's a strategy that allows TrustCo to play both offense and defense. In a rising rate environment, their focus on customer relationships and aversion to higher-cost funding options mitigates margin compression. In a declining rate environment, their nimble deposit pricing and long-term assets create the potential for margin expansion.

Of course, predicting the future of interest rates is a fool's errand. But by understanding the subtle dynamics of TrustCo's deposit strategy, we gain valuable insight into their resilience and potential for outperformance. The three-month shuffle might not make headlines, but its impact on TrustCo's future could be substantial.
