Hidden within the detailed pronouncements of Bank of Hawaii's Q1 2024 earnings call, a fascinating and potentially overlooked trend emerges. While analysts focused on the stabilization of deposit costs and the expected margin improvement, one critical factor slipped under the radar: the rapid and ongoing repricing of Bank of Hawaii's loan portfolio, driven by a consistent inflow of high-yielding new loans. This dynamic, if sustained, could transform Bank of Hawaii from a stable, low-growth institution into a surprising engine of profitability.

Bank of Hawaii has always been known for its rock-solid deposit base, a testament to its century-long presence in the unique Hawaiian market. This stability allowed them to weather the storm of rising interest rates with less turbulence than many mainland banks. Yet, the flip side of this enduring customer loyalty has been a slower pace of loan growth, averaging around 6.5% annually since 2019.

However, a closer examination of recent trends reveals a potential shift in this narrative. Bank of Hawaii's CFO, Dean Shigemura, highlighted the consistent cash flow from loan maturities and prepayments, forecasting it to remain at a robust $3 billion annually. This translates into a constant stream of funds available for reinvestment, supplementing the $7.2 billion in assets that naturally reprice each year.

The crucial detail lies in the reinvestment strategy. While runoff yields from maturing loans and securities hover around 2.1% and 4.6% respectively, Bank of Hawaii is actively deploying these funds into new loans with yields exceeding 7.5%. This significant spread, exceeding 3% in many cases, creates a powerful engine of net interest income accretion.

"Shigemura explicitly stated that this repricing dynamic is expected to contribute an additional $5 million in net interest income per quarter. Extrapolated over a full year, this amounts to a $20 million annual increase, a substantial figure for a bank with $113.9 million in net interest income in Q1 2024."

This higher-yield reinvestment strategy forms the basis for our hypothesis: Bank of Hawaii's margin, while showing promising signs of improvement, is likely being underestimated by the market. The current consensus anticipates margin expansion primarily driven by deposit cost stabilization. However, the powerful impact of loan repricing, if sustained, could supercharge this expansion, leading to greater profitability and potentially, a significant revaluation of Bank of Hawaii's stock.

Further strengthening this hypothesis is the concurrent slowdown in deposit mix shift. The rapid runoff from non-interest-bearing deposits, which plagued banks throughout 2023, has slowed dramatically at Bank of Hawaii. This suggests that their deposit base is approaching a point of equilibrium, allowing the benefits of loan repricing to flow directly to the bottom line.

Of course, several factors could disrupt this potential high-yield trajectory. A sudden surge in loan losses, driven by an unforeseen economic downturn, could erode the benefits of repricing. Similarly, a resurgence in deposit competition, perhaps fueled by aggressive actions from mainland banks seeking to expand into the Hawaiian market, could pressure funding costs and dampen margin expansion.

Despite these potential headwinds, the evidence suggests that Bank of Hawaii is quietly positioning itself for a higher-yield future. By leveraging its strong deposit base and actively deploying funds into high-yielding loans, they are creating a powerful mechanism for profitability. Whether this translates into a full-fledged awakening of the sleeping giant remains to be seen, but the signs are intriguing, suggesting that Bank of Hawaii may be poised to surprise the market with its future performance.
