What it means
When a bank fails, simply closing the doors would freeze payroll accounts, supplier payments and lines of credit for thousands of customers overnight. A bridge bank avoids that by transferring the deposits and the better assets into a newly chartered institution that the insurer owns and controls.
The failed entity's shareholders, and often its unsecured creditors, are left behind in the old shell. The insurer appoints a board and management, provides funding, and runs the bridge bank as a going concern while it markets the business.
Customers usually notice little beyond a change of name, which is the point, because continuity is what stops panic spreading to other banks. Regulators generally have a statutory time limit, commonly around two years with extensions, before the bridge bank must be sold or wound down.
The tool is used when no buyer can be found fast enough for a same-weekend sale. That happens with large or complex failures, where a buyer needs weeks of due diligence, or where several bidders need time to assemble financing.
It is also used when the regulator wants to separate the healthy business from litigation and legacy problems. The cost falls on the deposit insurance fund in the first instance, which in most systems is financed by levies on surviving banks rather than by general taxation.
If the eventual sale raises more than expected, the net cost falls; if asset values keep deteriorating, it rises. Recoveries from the failed entity's remaining estate can also reduce the final bill.
For a business banking with a failed institution, the practical points are simple. Deposits transferred to the bridge bank stay available and loan agreements generally continue on their existing terms, while uninsured balances may or may not be protected depending on the decision taken at the time.
Keeping a second banking relationship is the cheapest insurance against that uncertainty.
In practice
Real-world examples.
Example
A 60-person design agency banks with a failed regional lender. On the Monday its payroll runs as normal because the bridge bank has assumed all deposit accounts and the standing payment instructions transferred with them.
Example
A property developer has a $12,000,000 revolving construction facility with a failed bank. The bridge bank continues to fund drawdowns under the existing terms while the insurer markets the loan book, although the developer starts arranging a replacement lender in parallel.
Example
A technology company holds $9,000,000 in a single account at a failed bank, far above the insured limit. The regulator transfers all deposits, insured and uninsured, into the bridge bank, so the company loses nothing, but its board writes a new policy capping any single bank balance at $2,000,000.
Formula
Calculation
Formula: cash support required = liabilities assumed - estimated realisable value of assets transferred. Net resolution cost = cash support - premiums and proceeds recovered on sale.
Worked example: Fairmont State Bank fails with $12,000,000,000 of book assets. The insurer creates a bridge bank that assumes all $10,500,000,000 of deposits plus $200,000,000 of other liabilities, a total of $10,500,000,000 + $200,000,000 = $10,700,000,000.
The assets transferred are marked down to an estimated realisable value of $9,900,000,000, so the insurance fund must inject $10,700,000,000 - $9,900,000,000 = $800,000,000 of cash for the bridge bank to open with a balanced balance sheet on Monday morning.
Nine months later a healthy regional bank buys the franchise and pays a deposit premium of $250,000,000. The net cost to the insurance fund falls to $800,000,000 - $250,000,000 = $550,000,000, which is $550,000,000 / $10,500,000,000 = 5.2% of the failed bank's deposits. That percentage is the number resolution authorities are judged on.Case study
Seen in the real world.
Grantsville Community Bank is an illustrative, fictional lender with $4,000,000,000 of assets that failed after heavy losses on commercial property loans. No buyer could complete due diligence over a single weekend, so the regulator chartered a bridge bank on the Sunday evening and it opened on Monday under a new name.
The bridge bank assumed $3,600,000,000 of deposits and received assets valued at $3,150,000,000, so the insurance fund injected $3,600,000,000 - $3,150,000,000 = $450,000,000 of cash. Seven months later a larger bank bought the franchise and paid a $120,000,000 deposit premium, reducing the net cost to $450,000,000 - $120,000,000 = $330,000,000.
The illustrative point is continuity. Grantsville's 40,000 customers kept their accounts and its 900 borrowers kept their loans, so the failure never became a story about queues outside branches, which is the whole reason the bridge bank tool exists.
Watch out
Common mistakes.
- Assuming a bridge bank is a permanent institution, when it exists only until the business is sold or wound down.
- Believing shareholders of the failed bank are protected, when their stake is normally wiped out before the bridge bank opens.
- Treating the transfer of uninsured deposits as automatic, when whether they move across is a decision taken case by case.
Questions
People also ask.
Who owns and runs a bridge bank?
The deposit insurer or resolution authority owns it and appoints its board and management until a buyer is found.
How long can a bridge bank operate?
Typically up to about two years with possible extensions, though most are sold within months.
Does the taxpayer pay for it?
In most systems the deposit insurance fund pays, and that fund is financed by levies on surviving banks rather than by general taxation.
