Tremble in banks and stock markets on both sides of the Atlantic is fueled by the threat of the collapse of Silicon Valley Bank (SVB), a 40-year-old US bank that mainly finances startups.

Analysts and traders are concerned that the SVB may be just the tip of the iceberg, leaving European banking stocks as well as the Athens Stock Exchange under heavy pressure today.

SVB is down 60% on Wall Street yesterday as it liquidates its portfolio in a rush to raise capital, selling positions totaling $21 billion for a $1.8 billion loss. He also raised $500 million from venture capital firm General Atlantic.

Amid the massive outflow of deposits, the chief executive of SVB asked clients to remain calm.

But in the investment world, “People are asking who’s next,” Jens Nordwig, founder of analytics firms Exante Data and Market Reader, explains to Bloomberg. Concerns, of course, are related to the consequences of the Fed’s rate hike for banks.
