LONDON (Reuters) - Foreign exchange trading out of London declined 4 percent in October 2017 to $2.23 trillion, compared with six months earlier, thanks to a drop in volumes in cash spot and swaps, a semi-annual survey by the Bank of England showed on Thursday.
The survey showed spot turnover in London, the world's biggest currency trading hub, declined by $45 billion per day from six months ago to $677 billion daily.
The decline in volumes traded was across the board for all major currencies, according to the survey, perhaps a reflection of falling market volatility.
