Sawt Falasteen - Biden reassures Wall Street but European stocks slump

Meanwhile, US bond yields fell as investors judged the turmoil in the regional banking sector could push the Fed to become gun-shy on raising interest rates, a move which would be positive for stocks but pushed down the dollar.

After opening lower, Wall Street pushed into positive territory after about an hour of trading, with the Dow up 0.7 percent.

US President Joe Biden said Monday that "Americans can have confidence that the banking system is safe" as he vowed to push for tougher regulations on banks.

Fears that the collapse of Silicon Valley Bank (SVB) on Friday could spark contagion throughout the banking system forced the Fed, the Treasury Department and Federal Deposit Insurance Corp. over the weekend to promise to fully protect all depositors and give backup to any lenders struggling to find cash, providing easier terms on short-term loans.

On Sunday, New York regulators said they had closed another lender, Signature Bank.

Ipek Ozkardeskaya, senior analyst at Swissquote Bank said all the news about contagion risk following the collapse of SVB "will likely interfere with Federal Reserve (Fed) rate hike expectations, as well, as the Fed may want to think twice before stepping on the gas this month."

Briefing.com analyst Patrick O'Hare said the market is now showing an even chance of no rate hike at next week's Fed rate meeting, while after Fed chief Jerome Powell's remarks to lawmakers last week, over three-quarters of investor forecast a 0.5 percentage point hike in rates.

The Fed's sharp jump in interest rates that tamed inflation helped provoke SVB's collapse as the prices for securities on its books fell below their purchase price -- and this could be a problem for other banks.

Shares in First Republic Bank tumbled 59 percent, PacWest Bancorp 19 percent, Comerica 20 percent and KeyCorp 21 percent in morning trading.

"The Fed is now in question over even a 25-point hike at the next meeting," Strategic Alpha analyst Maurice Pomery told AFP.

"The issue for me is that many businesses were constructed on zero interest rates, leverage and debt model -- which with rising rates is no longer viable," he warned.

Fears about contagion dominated trading in Europe.

Germany's finance watchdog insisted the collapse of SVB posed no threat to financial stability, as did the Banque de France.

France's Finance Minister Bruno Le Maire told investors to "calm down" after shares in French banks tumbled.

Shares in French banks BNP Paribas fell 6.7 percent and Societe Generale 6.2 percent in afternoon trading. Shares in Italy's Unicredit tumbled 8.3 percent and Spain's Santander 7.9 percent. Deutsche Bank shares fell 5.6 percent.

Europe's main stock indices were down between two and four percent in late afternoon trading.

"Far from calming nerves, fear of contagion has ramped up further with investors dumping risk assets across Europe," City Index analyst Fiona Cincotta told AFP.

"Banks are leading the charge southwards with investors taking aim at Spanish and Italian banks, suggesting that these are considered the weakest links as fears rise."
