A small California lender has become the sixth U.S. bank to fail in 2026, and every one of its depositors kept their money. California regulators closed Nano Banc of Irvine on September 25, 2026, and the FDIC was appointed receiver. Sunwest Bank assumed all of Nano Banc’s deposits, insured and uninsured alike, so no depositor lost a dollar.
What Regulators Say Went Wrong at Nano Banc
The FDIC published its Failed Bank Information page for Nano Banc on September 25, 2026. California’s Department of Financial Protection and Innovation issued its own announcement, stating that the state seized Nano Banc, ending years-long struggles culminating in significant financial loss. American Banker reported on September 26, 2026 that an embattled California bank was the latest to fail.
California regulators said Nano Banc failed to follow its latest enforcement order and showed years of executive mismanagement.
An enforcement order is a formal directive from a bank regulator requiring a bank to fix specific problems by set deadlines. Typical demands include raising capital, replacing management, and tightening lending and risk controls. If a bank misses the requirements, regulators escalate, and closing the institution is the final tool available to protect depositors.
How the Sunwest Deal Protected Every Account
The FDIC said: “Nano Banc’s sole branch will reopen as a branch of Sunwest Bank during its normal business hours on Monday, September 28, 2026. Depositors of Nano Banc will automatically become depositors of Sunwest Bank.”
As of June 30, 2026, Nano Banc held $736 million in total assets and $686 million in total deposits. Sunwest assumed $605M in deposits and purchased roughly $476 million of Nano Banc’s assets. The deposit figure shrank from the June balance sheet due to regulatory pressure.
The preliminary estimated cost to the FDIC’s Deposit Insurance Fund is approximately $114 million. The Deposit Insurance Fund is the pool the FDIC uses to protect depositors when banks fail, and it is financed by assessments paid by insured banks rather than by taxpayers. That preliminary figure can change as the FDIC works through the remaining assets.
Six Bank Failures in 2026 and a Common Thread
investingLive reported that U.S. bank failures in 2026 now number six with the seizure of Nano Banc. The other five are:
- Metropolitan Capital Bank & Trust of Chicago, Illinois
- Community Bank and Trust – West Georgia of LaGrange, Georgia
- Kentland Federal Savings and Loan Association of Kentland, Indiana
- Small Business Bank in Kansas
- Tioga-Franklin Savings Bank of Philadelphia, Pennsylvania
The FDIC has published Failed Bank Information pages for the Chicago, LaGrange, Kentland and Philadelphia institutions, and it announced that Second Federal Savings and Loan Association of Philadelphia assumed all deposits of Tioga-Franklin.
Based on reporting reviewed by 24/7 Wall St., nearly all of this year’s failed banks had prior regulator consent orders or enforcement actions before closing.
According to Bankrate, six failures already exceeds every full year from 2015 through 2025, when the maximum was five, reached in 2023 and in 2016. 24/7 Wall St. has not independently verified those annual counts. Bankrate maintains a list of failed banks covering 2009-2026, and Forbes maintains an analysis of failed banks by year, size and more.
What Nano Banc Customers Experienced
The resolution process worked as designed. The bank closed on a Friday, its branch reopened under new ownership on the next business day, and account holders became Sunwest customers without taking any action.

Why a Higher Failure Count Signals Stress at the Edges
Six small institutions failing in a single year marks a real uptick, and the pattern of prior enforcement actions points to problems regulators had flagged in advance. So far in 2026, the failures have been small, resolved through orderly transfers, and in the case of Nano Banc, every depositor was made whole.
