Deutsche Bank (symbol DB on the above chart) closed at $16.50 on the New York Stock Exchange on February 10 of this year. It closed at $10.23 yesterday – a decline of 38 percent in a month’s time. That’s a big problem because Deutsche Bank is heavily interconnected to Wall Street banks via derivatives. According to Deutsche Bank’s most recent annual report, as of December 31, 2020, it held $35.4 *trillion* in notional derivatives. (Notional means face amount.
