First Citizens shares soar 45% after the bank buys a large chunk of failed Silicon Valley Bank

First Citizens BancShares will buy Silicon Valley Bank's deposits and loans, the U.S. Federal Deposit Insurance Corporation said Monday, just over two weeks after the biggest U.S. banking collapse since the global financial crisis.

First Citizens shares jumped more than 45% during Monday morning trading on Wall Street.

The deal includes the purchase of approximately $72 billion of SVB assets at a discount of $16.5 billion, but around $90 billion in securities and other assets will remain "in receivership for disposition by the FDIC."

"In addition, the FDIC received equity appreciation rights in First Citizens BancShares, Inc., Raleigh, North Carolina, common stock with a potential value of up to $500 million," the FDIC said in a release.

The deal comes after the regulator transferred all SVB deposits and assets into a new "bridge bank" earlier this month in an effort to protect depositors of the failed lender.

"The 17 former branches of Silicon Valley Bridge Bank, National Association, will open as First-Citizens Bank & Trust Company on Monday, March 27, 2023," the FDIC statement said Monday. First-Citizens Bank & Trust Company is a subsidiary of First Citizens BancShares.

"Customers of Silicon Valley Bridge Bank, National Association, should continue to use their current branch until they receive notice from First-Citizens Bank & Trust Company that systems conversions have been completed to allow full-service banking at all of its other branch locations."

First Citizens and the FDIC also entered into a "loss-share transaction" — in which the FDIC absorbs part of the loss on a particular pool of assets — on the commercial loans purchased from the SVB bridge bank.

"The loss–share transaction is projected to maximize recoveries on the assets by keeping them in the private sector. The transaction is also expected to minimize disruptions for loan customers," the FDIC explained.

The regulator added that the estimated cost of SVB's failure to its Deposit Insurance Fund will be around $20 billion, with the exact cost determined once the receivership is terminated.

Regulators closed down SVB, a big name in the tech and venture capital sector, and took control of its deposits March 10.

The collapse came after the bank's clientele withdrew billions from their accounts and the value of assets previously viewed as safe — such as U.S. Treasury bills and government-backed mortgage securities — dropped dramatically in the face of the Federal Reserve's aggressive interest rate hikes.

This left the bank floundering as it attempted to raise $2.25 billion to meet clients' withdrawal needs and fund new lending.

As of March 10, the SVB bridge bank had around $167 billion in total assets and approximately $119 billion in total deposits, the FDIC confirmed.

SVB's collapse sent shockwaves through global banks and was cited as one of the catalysts for Swiss giant Credit Suisse's eventual downfall and emergency rescue by domestic rival UBS.

However, many analysts believe the ensuing market volatility has been unwarranted given the "idiosyncratic" flaws that left the likes of SVB and Credit Suisse exposed and caused a loss of investor confidence.
