Although Deutsche Bank doesn’t break down the numbers, some further proof of how profitable FX is for those who can manage flow came with the release of first-quarter figures from the bank. Revenues for what it describes as sales and trading (debt), which includes FX, came in at a whopping €3.8 billion. And even though volumes are widely reported to have dropped this quarter, Deutsche says its revenues from FX were double what they were back in the same quarter of 2007.
