While the U.S. exchange traded fund industry is hovering around $2 trillion in assets under management, ETF usage across the pond is also expected to quickly pick up momentum.

According to a recent Greencwich Associates survey, European institutional investors, including pension funds, insurers and asset managers, hold ETFs for a wide range of purposes and sit on them for much longer than previously thought, according to the Automated Trader.

“The results of this study suggest that ETFs will continue to grow in Europe in terms of both number of institutional users and size of institutional allocations,” according to Greenwich Associates.

While Europe’s ETF industry is not as large as the U.S., European investors are quickly throwing more assets into ETF investments. For instance, one in five European institutional investors intended to increase their use of ETFs over the next three years, and about one in ten expect to raise allocations by over 10% within that period.

According to ETFGI data, there were 2,106 ETFs/ETPs on European markets with $460 billion in assets under management as of the end of December 2014. [ETFs/ETPs Gathered Record Assets in 2014]

On the Greenwich survey, about 71% of European institutional investors revealed that they use ETFs within their multi-asset funds, over a third of respondents employ ETFs within equity funds, 52% say utilize ETFs for domestic bond exposure and 59% use ETs for international fixed-income exposure.

While short-term moves may reveal significant asset flows that can only come from institutional-sized investors, many European institutions are holding onto ETF positions for a significant period, with 6% of respondents using ETFs for tactical adjustments and 2% only held them for one month or less. On average, pension funds held ETFs for an average 29 months, the longest of the group.

Among the top factors for choosing an ETF, institutions pointed to a fund’s expense ratio, liquidity or trading volume, underlying benchmark and performance. However, different institutions have varying priorities. For instance, insurers mark ETF liquidity as the most important factor while pensions point to expense ratio or costs.

“These features will be important for European institutions as they move to diversify portfolios away from the traditional domestic and government bonds that have made up the bulk of their investments, and as the increasing complexity of their portfolios prompts institutions to outsource assets in search of external expertise and skill sets that are not in abundance in their internal management teams,” according to Greenwich Associates.

European insurers are also using ETFs as a liquid way to access international equities and diversify a portfolio, with 76% of insurers using ETFs for international exposure, compared to 57% to purchase domestic positions.

Lastly, pension funds were the most likely to act as strategic ETF users and also used the products to diversify a portfolio. About 88% of pension funds ETF investors utilized the funds to access international equities or almost three times the those using ETFs for domestic exposure.
