Customers Bancorp, Inc. (CUBI)

“A bank is only as good as the deposits it can hold and the loans it can make without losing money.”

Customers Bancorp, headquartered in Wyomissing, Pennsylvania, is a mid-sized bank holding company that operates Customers Bank, a lender focused on commercial and industrial customers in the Northeast and mid-Atlantic regions and on residential mortgages across a wider geographic footprint. Founded in 1989, the bank was for decades a quiet regional player; it grew through acquisition and organic expansion and by the 2010s had built a meaningful balance sheet. The basic business is unchanged from most regional banks: borrow cheaply (via deposits and wholesale funding), lend at higher rates, pocket the spread, and manage credit risk through underwriting discipline. That model has become harder to execute as margins compress and deposit competition intensifies.

A growth story that ran into structural headwinds

Customers Bancorp’s early history was steady but unremarkable — a community bank in a mid-Atlantic state doing what community banks do. The turning point came in the 2010s when the bank pursued an unusual strategy: it decided to become a specialist in commercial and industrial lending, particularly to businesses in the construction, healthcare, and light manufacturing sectors. The bank also built a significant residential mortgage business that operated across the country, originating mortgages for sale to investors or held for the balance sheet. This dual approach — local deposit gathering, national mortgage distribution, regional C&I focus — was meant to diversify revenue.

For a decade it worked. Low interest rates, a booming housing market (post-2012 recovery through 2021), and steady demand for business credit from mid-market companies generated strong earnings. The bank’s net interest margin (the spread between what it earned on loans and what it paid on deposits) stayed healthy because rates were so low that even small deposit rates felt generous to savers. The bank also grew through acquisitions, including Citizens & Farmers Bank in 2020, which expanded its geographic footprint and deposit base.

Then the Federal Reserve raised rates aggressively starting in March 2022, and the calculus inverted. Higher rates meant depositors could earn real yields elsewhere; they moved money out of low-rate savings accounts and into money-market funds and Treasury bills. Banks that had grown accustomed to cheap deposits suddenly faced a choice: raise deposit rates to match market yields and shrink margins, or lose deposits and shrink the balance sheet. Customers Bancorp faced the same squeeze as every other regional bank, but with some particular vulnerabilities.

The mortgage machine ran into profitability trouble

Residential mortgage origination became less profitable almost overnight. When rates rose from 3 percent to 7 percent, the implied price of a mortgage fell dramatically. A homebuyer who would have paid $400,000 for a home at 3 percent could only afford $300,000 at 7 percent. Originations volumes collapsed; the business that had been a growth driver became a cost center. Mortgage originators — including Customers’ retail and wholesale mortgage operations — either reduced staff and closed branches or took losses on every loan they generated. Customers Bancorp had built a significant mortgage business; watching it shrivel was a body blow.

The company also carried mortgages on its balance sheet, particularly adjustable-rate mortgages (ARMs) that were originated years earlier at very low rates. As those loans matured and customers sought to refinance, the mortgages left the balance sheet, forcing Customers to reinvest at much higher rates but lower prices. This is an every-bank problem, but it stings more for a bank that had made mortgages a strategic focus.

Where the real risk lives

The first risk is deposit outflows. Customers Bancorp has a customer base of small and mid-market businesses and individual depositors who will flee to higher-yielding alternatives if the bank cannot match market rates. Unlike JPMorgan, which can offer low rates and keep deposits because customers need its payments infrastructure and lending capacity, Customers Bancorp offers vanilla deposit products. There is nothing holding a depositor there except the current interest rate. If rates stay high, the bank must pay up to keep deposits, which crushes margins. If rates fall, the bank makes money again but the reprieve is temporary.

The second risk is credit. When the economy softens, businesses stop repaying loans and mortgage defaults rise. Customers has C&I exposure to construction and healthcare, both of which are sensitive to economic cycles. The bank’s underwriting discipline is strong, but in a severe recession, losses can surprise on the upside. A major credit loss could force the bank to set aside significant reserves, hit earnings, and trigger questions about whether the bank’s capital ratio is adequate.

The third risk is balance-sheet shrinkage. If the bank cannot fund itself with deposits, it must either shrink loans or fund itself with expensive wholesale borrowing. Shrinking means walking away from profitable customers and losing market share. Expensive wholesale funding means the spread narrows so much that the bank barely makes money. Either way, profitability and shareholder value are impaired.

The fourth risk is strategic obsolescence. Regional banks have not grown revenue much in the last decade — they have mostly maintained earnings through cost-cutting and by taking on more risk. Customers Bancorp is better-positioned than some peers (it has scale, it has diversified revenue, it has a decent deposit base), but it is not immune to the broader headwinds facing the industry. Tech-enabled fintech lenders are taking share in C&I; online banks and brokers are taking deposits; credit-card companies are offering financing that competes with bank loans. A bank’s competitive moat (its customer relationships and its deposit franchise) is real, but it is not durable forever.

How to read the company

Customers Bancorp’s quarterly earnings reports and 10-K filing show the loan portfolio, deposit trends, and net interest margin in detail. The most important metrics to track are net interest margin (is it staying flat, growing, or shrinking?), deposit growth or decline (can the bank fund itself?), nonperforming loans (an early signal of credit stress), and loan-loss reserve levels (is management comfortable with credit quality?). The company also discloses its mortgage origination volumes; watch whether the mortgage business is stabilising or still shrinking. Dividend sustainability is important for income investors; if earnings are under pressure, the bank may need to cut the dividend to preserve capital, which typically sends the stock down sharply.

Regional banks are also sensitive to interest-rate expectations. Any shift in what investors believe the Fed will do with rates moves the sector immediately. For Customers Bancorp specifically, watch economic data from its geographic footprint (Northeast and mid-Atlantic) and any management commentary on loan demand and deposit competition. The bank is also subject to periodic regulatory exams and capital requirements; any finding or enforcement action could limit dividend policy and capital flexibility. The company’s largest risk is that the structural shift in deposit dynamics never reverses, leaving the bank permanently operating at lower margins than it expected — a fate that has befallen many regional banks over the past two years.
