The Federal Reserve raised rates 25 basis points this past week. It was the first increase since 2023. The Fed had held policy steady through its first five meetings of 2026.
The commentary will focus on borrowing costs. The more useful question for enterprise banks is different. When the rate environment reverses without warning, which institutions can respond quickly? Which can reprice and launch new products fast enough? Which ones are still waiting on a systems team?
Scale was supposed to be the advantage here. A large deposit base, a broad commercial client roster, treasury relationships built over decades. None of that matters if the infrastructure underneath it can’t move at the speed the moment requires.
Deposits Don’t All Move at the Same Speed, and Neither Do Banks
Every institution talks about deposit retention as a pricing exercise: offer a competitive rate, keep the balance. That framing misses the more consequential split underneath it.
Some deposits are tied to how a business operates. These include payroll funding, receivables, and card settlement. They also include working capital. A company can’t move these balances without disrupting its own operations. Those balances are sticky because leaving costs more than the rate gap is worth.
Other deposits are parked cash with no operational tie to the institution at all, and they move the moment a better rate shows up. Regulators already draw this line: operational deposits get more favorable liquidity treatment under Basel III because they are expected to have lower runoff rates under stress, not because they cannot move.
For enterprise banks, the exposure isn’t a knowledge gap about which deposits are which. It’s a speed gap. A competitor built on configurable infrastructure can adjust pricing or launch a treasury product faster than a bank dependent on a core-vendor timeline.
A competitor built on configurable infrastructure can adjust pricing or launch a treasury product faster than a bank dependent on a core-vendor timeline. Non-operational deposits don’t wait for that timeline.
Market Rates Are Raising the Pressure
The 10-year Treasury hit 5.04% on September 15. That was its highest level since July 2007. It all signaled broader market pressure.
Money market fund yields moved as the 10-year Treasury climbed. Banks able to respond quickly were better positioned to compete for rate-sensitive balances.
The issue is not simply where rates are today. It is how quickly banks can respond when market conditions change.
The Margin Pressure Enterprise Banks Can’t Out-Scale
Scale doesn’t neutralize duration risk. If anything, it compounds it.
Many institutions hold long-duration securities and fixed-rate loans originated in a lower-rate environment. When a reversal like this hits, those holdings lose value relative to current market yields.
Unrealized securities losses across FDIC-insured institutions stood at approximately $326.7 billion in the second quarter of 2026. The total remained elevated even before this latest rate move, and higher long-term yields could put renewed pressure on that recovery. Sources: FDIC Quarterly Banking Profile and Premier Insights.
Combine that with deposit costs repricing faster than loan yields adjust, and an enterprise bank is exposed on both sides of the balance sheet, at a scale that makes the exposure larger in absolute terms even when the ratios look similar to a smaller institution’s.
Fee Income Becomes More Important
This is exactly where fee income earns its place, and enterprise banks have more raw material to work with than almost anyone in the industry: existing commercial relationships, embedded payment volume, card programs, treasury activity already running through the institution. The opportunity is to monetize activity the bank already supports rather than wait for the balance sheet to reprice.. The banks that can turn existing commercial activity into monetized, embedded revenue, without waiting on a lengthy product build, have a real advantage the moment margin gets squeezed. The ones that can’t are leaving fee income on the table precisely when they need it most.
The Balance Sheet Cost of Moving Too Slowly
There’s a fourth number worth watching, and enterprise banks are already living it. When deposits leave for higher-yielding alternatives faster than the loan book shrinks, loan-to-deposit ratios climb, and institutions have to fund the gap somewhere.
Commercial banks are already doing exactly that. Federal Home Loan Bank advances rose 20% in the second quarter to $810.7 billion, up from $676.7 billion at year-end 2025, with commercial banks accounting for roughly 90% of the $134 billion increase. The Federal Home Loan Bank of New York, which supplies liquidity to Wall Street banks, saw the largest jump of any district, up 38% to $127.7 billion. That’s not a community bank story. The increase shows that even large institutions rely on wholesale funding when liquidity needs rise.
Raising CD Rates Isn’t a Complete Fix
Some institutions tried to win deposits back directly instead, raising CD rates to compete with money market funds. That’s not a fix either. A CD priced to compete with a money market fund is still rate-driven money. Winning it back means paying an elevated rate to hold it for a year, and when that CD matures, likely after another rate move or two, the same depositor shops again. The balance sheet hasn’t improved. It’s rented stability at a cost.
What Actually Separates Banks in a Moment Like This
What this reversal exposes is which institutions have the infrastructure to respond to all four in weeks instead of quarters, and which ones are still negotiating dated solutions while the moment passes.
Enterprise banks don’t lack the client relationships, the deposit base, or the commercial activity to compete. What separates the institutions that come out of this cycle stronger is whether their infrastructure can actually act on what they already have, repricing, launching, orchestrating new revenue from existing volume, at the speed the market is now demanding. The institutions still running on infrastructure built for a slower rate environment will spend the next several quarters reacting to decisions the market already made for them.
