Santander and Deutsche Bank have failed a US stress test designed to assess their ability to cope in another financial crisis.

The tests, carried out by the Federal Reserve on banks with assets worth more than $50bn (£33bn), gauge whether or not banks operating in the US would have the "ability to lend to households and businesses even in times of stress".

It is the second year in a row that Santander has failed the stress tests.

Bank of America has also been asked to review financial plans as a result of "certain weaknesses". But 28 banks in total passed the stress tests.

Previously, banks that have failed the US stress tests have been forced to suspend dividend payments to shareholders and international lenders, like Santander and Deutsche Bank which are based in Spain and Germany respectively, can be prevented from sending their earnings back to the parent companies.

It is not yet known how the banks will be punished.

Deutsche Bank said that it had hired 1,800 new staff "dedicated to ensuring that its systems and controls are best in class".

Santander US chief executive Scott Powell said the bank still has "meaningful work to do to meet our regulator's expectations and our own standards of excellence".

Bank of America said: "We are committed to meeting the requirements in the time frame the Fed has established."
