Bank-related fears drag down global stock markets.

US stock futures fell on Friday as concerns over financial stability continue to weigh on the banking sector. The pressure in oil prices comes after Energy Secretary Jennifer Granholm told lawmakers that refilling the country's Strategic Petroleum Reserve may take several years. Hindenburg Research's accusations of fraud against Square led to a 4% drop in pre-market trading on Friday, while Coinbase dropped another 2% after receiving a Wells Notice from the SEC. Deutsche Bank and UBS also fell more than 10% and 6%, respectively, as Euro banks continue to feel the aftermath of Credit Suisse's downfall.
