Nano Banc had one branch, and between the closure on Friday, September 25, 2026, and the opening of business the following Monday, no customer could walk into it. On Monday, September 28, the same branch reopened under a different name: Sunwest Bank, the Utah institution that took over Nano Banc’s deposits. By the calendar that is the next business day after the failure, with a weekend in between.
What a customer finds on arrival is a Sunwest Bank branch, open during normal business hours, holding deposits the FDIC says are still insured. The record of what changed and what did not comes from one federal release.
Friday to Monday: counting the business days
The Federal Deposit Insurance Corporation’s September 25 press release sets the schedule in one sentence: “Nano Banc’s sole branch will reopen as a branch of Sunwest Bank during its normal business hours on Monday, September 28, 2026.” California’s Department of Financial Protection and Innovation had closed the bank that day and appointed the FDIC as receiver.
September 25, 2026 was a Friday. Saturday and Sunday are not business days, so Monday is the first business day after the closure, not the second. The dates are the firm part: closed Friday, September 25, reopened Monday, September 28, three calendar days apart.
What carried through the weekend
The money never stopped being reachable, according to the release. “Customers of Nano Banc will have immediate access to their deposits,” it says. “Over the weekend, they can access their deposits by writing checks or using ATM or debit cards. Checks drawn on Nano Banc will continue to be processed.”
Two instructions followed from that. Depositors were told that “there is no need for customers to change their banking relationship,” because the deposits Sunwest assumed “will continue to be insured by the FDIC.” Borrowers were told to keep paying: “Loan customers of Nano Banc should continue to make their payments as usual.” Neither instruction asks anyone to visit the branch, fill in a form or open a new account.
The phone line that stood in for the counter
For anyone who did want an answer before Monday, the FDIC staffed a toll-free line at 1-866-314-1744. The release gives the schedule in Pacific time:
- Friday, September 25: the evening of the closure, until 8:00 p.m.
- Saturday: 9:00 a.m. to 5:00 p.m.
- Sunday: 12:00 p.m. to 4:00 p.m.
- Monday: 8:00 a.m. to 5:00 p.m.
- After Monday: weekdays, 8:00 a.m. to 4:00 p.m.
A second FDIC number, 1-877-ASK-FDIC, appears on the agency’s deposit insurance page, which directs readers to it for questions such as what happens if a bank fails.
One branch, not a network
The scope of the reopening is narrow. The release speaks of Nano Banc’s “sole branch,” and American Banker’s report on the failure says the defunct Irvine lender “had only a single branch, which will reopen on Monday as a Sunwest branch.” Nothing in either source says Sunwest took on additional offices, kept a Nano Banc name on the door or changed hours beyond what the release lists. The release also does not print the branch’s street address; it points readers to the FDIC’s failed-bank page for Nano Banc for further detail.
The buyer has done this before. Carson Lappetito, Sunwest’s president and chief executive, told American Banker that the bank was “honored to once again be selected by the FDIC as the acquiring institution,” calling it the sixth time Sunwest had completed such a transaction. For customers, that history is context and not a guarantee: the sources read for this article describe the acquirer’s record and say nothing about service levels or fees at the reopened branch.
That last gap is worth stating plainly. The FDIC’s release covers insurance, access to deposits, checks, cards, loan payments and a help line. It does not say whether Sunwest’s account terms, fee schedule or online banking replaced Nano Banc’s on Monday or later, and no source read here answers it.
What the record does support is short. The FDIC said on September 25 that Nano Banc’s only branch would reopen as a Sunwest Bank branch on Monday, September 28, with deposits insured and accessible throughout the weekend.
The questions a reopened branch does not settle
A Nano Banc customer who reached the Sunwest branch on September 28 found the access and insurance questions answered in the FDIC’s release. Left open is the paper side of an account that has changed hands: which deposits came from protected sources, and what to record if a creditor or collector later contacts the new bank or the account holder.
The Bank Account & Debt Protection Kit sets out the frozen-account response and keeps a protected-funds and dispute log, which is what a customer needs when an account changes hands and the paperwork has to be reconstructed.
