Inflows into exchange traded funds accelerated to a record $105bn in the first six months of the year, as optimism for the future was fuelled by a new survey saying the market will grow yet further over the next three years.

BlackRock, the world's biggest ETF provider, said the first half inflows represented an increase of 16% compared to the first half of last year. June attracted $20bn, against $18.3bn a year earlier. Fixed income ETFs represented 41% of inflows, a rise of 114% on the previous year.
