Banks

The interbank market caters for both the majority of commercial turnover and large amounts of speculative trading every day. Many large banks may trade billions of dollars, daily. Some of this trading is undertaken on behalf of customers, but much is conducted by proprietary desks, which are trading desks for the bank's own account. Until recently, foreign exchange brokers did large amounts of business, facilitating interbank trading and matching anonymous counterparts for large fees. Today, however, much of this business has moved on to more efficient electronic systems. The broker squawk box lets traders listen in on ongoing interbank trading and is heard in most trading rooms, but turnover is noticeably smaller than just a few years ago.
