Conway National Bank's Quiet Dominance on the Grand Strand
Here is the number that stops you cold: Conway National Bank holds the largest deposit share in Horry County, South Carolina, ahead of 20 other institutions including Truist, Wells Fargo and Bank of America, and has every year since at least 2021. In the first half of 2026 it did that while running a 47.9% efficiency ratio. That combination is rare. Most banks that dominate a market spend their way there. CNB does it by being disciplined.
This is a $2.0 billion bank based in Conway, in business since 1903, with 16 offices across Horry and Georgetown counties. No flashy fintech partnerships, no press releases about AI, no acquisitions. Just more than 120 years of compounding community relationships in a county that keeps growing around it.
The question worth asking: how long does that formula hold as the county transforms underneath it?
The Market That Moved In
Horry County had an estimated 413,391 residents in July 2024, up 17.8% from the 2020 census, according to the Census Bureau. Builders pulled permits for 7,331 new housing units in the county in 2024 alone. The people arriving are not just retirees looking for warm weather, though there are plenty of those. Remote workers, families chasing coastal affordability, and second-home buyers who found they could work from Pawleys Island as easily as from a city office.
Most banks that dominate a market spend their way there. CNB does it by being disciplined.
CNB's mortgage data captures the shift. HMDA filings show the bank originated 329 home loans in 2025, up from 309 in 2024, for $82.1 million. Of those, 161 were purchase loans and 131 were refinances. Every one was conventional: no FHA, VA or USDA loans in either year.
The Georgetown County footprint tells a more interesting story. CNB made 27 loans there in 2025, at an average of about $599,000, nearly three times its Horry County average of about $205,000. In 2024 it made 41 loans there at about $352,000. Fewer loans, much larger ones. The Waccamaw Neck corridor (Pawleys Island, Murrells Inlet, Litchfield Beach) is a high-income second-home and retirement market, and CNB already has branches in it.
The bank's messaging leans on community roots, and that works well for the long-tenured customer who wants to call someone they recognize. It works less well for a retired couple from out of state buying a $600,000 home in Pawleys Island, with pension and brokerage income, who has never been inside a Conway branch.
The Efficiency Machine and Its Limits
CNB earned $23.2 million in 2025, up 26.5% from 2024, for a 1.23% return on assets. The first half of 2026 was stronger, from the FDIC call report:
- Net income of $13.9 million, up 34.7% from a year earlier
- Return on assets of 1.42%, up from 1.11%
- Net interest margin of 3.31%, up from 2.98%
- Efficiency ratio of 47.9%, down from 52.9%
- Noncurrent loans at 0.02% of the book
Net loans stood at $856 million in June, up 3.6% in a year: $296 million in nonfarm commercial real estate, $259 million in 1-4 family mortgages, $125 million in construction, $97 million in C&I and $59 million in consumer loans. Noninterest expense for all of 2025 was $34.5 million. That is a lean cost base for a $2 billion bank, and it means every hour of operational friction shows up in the ratio.
That is where growth gets complicated. Scaling from about 330 mortgage originations a year to 450 or 500 will not come from another branch. It comes from compressing the time and labor per loan. A processor chasing pay stubs, calling employers, waiting on bank statement PDFs and keying income into the loan system is a cost that rises in step with volume. CNB's efficiency depends on breaking that link.
What the In-Migrant Borrower Actually Looks Like
The Conway National borrower in 2026 is more complex than in 2006, or even 2016.
Picture a retiree who just bought a primary residence in Little River: Social Security, a pension from a former employer, a brokerage account paying dividends, and a small rental property in another state. No W-2. Several income streams, documented across several institutions. Verifying that by hand takes weeks, not days.
Or a remote software engineer who relocated from the Mid-Atlantic, started the current job six months ago, still owns a condo back home, and expects the digital experience of a national lender.
These borrowers are not edge cases. They are a growing share of purchase mortgages in a county adding thousands of housing units a year. The branch-centric model that serves a multigenerational Conway family well creates friction for someone who moved from 700 miles away and needs to close in 30 days.
CNB's website reflects its roots. As of October 2026, its mortgage and construction page offers a payment calculator but no online application, its home equity page asks borrowers to stop by an office, and its business loan page has a contact form rather than an application. The CNB2GO mobile app serves existing customers well. Those are not criticisms of a bank that has compounded impressively for 120 years. They are observations about where friction builds as the borrower changes.
The Waccamaw Neck Opportunity
A buyer purchasing a $600,000 property on the Waccamaw Neck is often comparing CNB with a regional bank that has a digital application, or a national lender promising a fast close. CNB's advantages there are local knowledge, relationships with the Grand Strand real estate community, and decades of trust. Those matter. But a buyer purchasing remotely, coordinating through a local agent and trying to close before the school year starts also notices how quickly a bank can verify their assets and income.
The faster that verification happens, the more of that segment CNB can capture without adding an underwriter.
The faster that verification happens, the more of that segment CNB can capture without adding an underwriter. At an average loan near $600,000, each additional Georgetown County purchase is worth roughly three Horry County loans in volume.
Where the Trajectory Points
Conway National has built something hard to replicate: the top deposit share in a fast-growing coastal market for six straight Summary of Deposits reports, $856 million in loans, and profitability most community banks only read about in peer reports. The foundation is strong.
The next phase will test whether a relationship-first, branch-anchored model can absorb a borrower population that looks less and less like it did ten years ago. The banks that capture the most of Horry County's growth will be the ones that can verify a retiree's pension, a remote worker's employment and a second-home buyer's reserves in hours rather than days. For a bank already running below a 48% efficiency ratio, the operational leverage in getting there is substantial.
