FRANKFURT (Reuters) - The German online bank of BNP Paribas has been temporarily unavailable for clients seeking to log into their accounts via the internet due to a spike in customer demand.

“We have seen up to the tenfold in volumes mainly related to equities and derivative trades,” a spokesman for Consorsbank said on Friday, adding that the situation had improved but was not yet fully resolved.

Consorsbank has about 1 million customers.
