Here is an explanation of the events.
The events
As its name indicates, Silicon Valley Bank is a bank for the Silicon valley. Many of its clients are small start-ups, who rely on their investors’ cash to pay their employees and fund their growth. The bank apparently has business relations with nearly half the start-ups of the region.
There are several concomitant factors:
- After a 30% market drop at the start of COVID, the low-rate environment has fuelled a market rally. The S&P went from a low of 2,300 to a top of 4,700.
The restart of the economy caused inflation, and the central bank started to raise rates again. The short-term interest rates have risen, from virtually zero to over 4.8%.
- The equity markets dropped, dropping to a low of ~3,600 or -25%.
- The rumors of a further rate rise, a further market downfall, and the risks of recession have covered all the headlines.
- Who wants to invest in equities and start-ups right before an economic crash? Investors have stopped funding start-ups – slow down of IPOs and private equity offerings.
- Those start-ups have used their cash, drawing altogether large amounts from SVB. Some failed.
- SVB was using the cash deposit and investing into long-term debt. The thrift was positive last year. It is now negative, due to the recent inversion. The bank was accruing running continuous losses.
- Worse, SVB had to sell those bonds to fund the cash withdrawals. It was forced to liquidate large bond positions.
- Since the long-term rates have also risen, those bonds are sold apparently below their accounting value – generating losses, if not mark-to-market losses. The announcement of the share offering notably had this sentence, mentioning ‘tax losses’:
- The bond sale losses added to the downgrades losses of SVB’s loans (and possible equity investments) in its start-up borrowers.
To maintain its capital ratios, SVB announced a capital raise, which didn’t go too well as its stock price kept on falling. The bank’s stock dropped 60%.
- It eventually tried to look for a buyer altogether, an effort which failed as well.
- A classic run on the bank followed. Many start-ups pulled their deposits.
- The company became belly-up two days after announcing its capital raise.
The FDIC has now stepped in and taken control of SVB’s assets. The insurer has already created a new bank and transaction facilities, and will keep on honoring up SVB’s transactions and withdrawals to $250,000 per account, starting on Monday.
Any small company or individual with more than this amount will become a first-line creditor in the bankruptcy proceedings. That will not be pleasant for many: uncertainty, delays, and very likely losses down the road.
The FDIC has not yet confirmed the amount, but apparently 90% of the bank’s assets are uninsured.
The questions

- Why did SVB wait for so long to raise equity? It is their lack of action in the past, combined with the announcement, which generated the bank run. There’s a Chief Risk Officer who will not get a job anytime soon.
- Why did the sale of bonds create a tax loss? $1.8 bn of tax losses on a $21 bn sales, aka 8.5%, indicates that the bond mismarking were probably much bigger (at 25% tax, the bonds would have been 35% mismarked). A proper valuation would have forced the bank to realize its losses as the long-term yield rose, not when it sold those bonds.
- More importantly, who else will be hurt by the losses? What contagion can we expect?
- Many start-ups will go belly-up.
- Many investment PE/VC funds will have to declare losses. Their investors could have financial difficulties.
- Did SVB owe large sums to other important financial companies? Nobody knows yet.

But Silicon Valley will suffer for sure. Some angel investors will become graveyard gnomes.
PS: The rumor is that $2bn of SVB withdrawals went to Brex, another Silicon Valley bank. That bank may enjoy the new cash flow, but it probably has a bunch of loans with other local start-ups… Bis repetita?
