Goldman Sachs has become the biggest casualty of the second quarter trading slump so far – with a 63% decline in revenues from its fixed income, commodities and currency division, compared to the previous quarter.

The bank revealed in its second quarter results - which were described by chief executive and chairman Lloyd Blankfein as "disappointing" - that revenues at the unit had fallen to $1.6bn. This was a 53% fall on the same period last year.
