Pre-tax profits at Barclays' corporate and investment banking unit more than doubled in the third quarter as revenues from its credit business surged nearly three quarters, complemented by gains in equities and banking.

Barclays, one of the first non-US banks to report third-quarter figures, on October 27 said profits at its CIB arm totalled £885 million, more than double the £358 million in the third quarter of 2015.
