Monthly recap: Momentum maintained
Net inflows into Europe-domiciled ETFs ticked up in May, ending with $44.3 billion – $2.1 billion more than the prior month. Markets stayed constructive in May as geopolitical tensions showed signs of easing, driving lower oil prices, softer yields and continued strength across major equity markets.
Equity ETFs captured $28.3 billion of net inflows in May. After a record-breaking April, core equity ETF flows eased slightly to $20.1 billion in May, with investors favouring global, US and developed market exposures. Sustainable and thematic equity ETFs also enjoyed a relatively strong month.
Fixed income ETFs saw $15.6 billion of net inflows in May – a strong uptick following $10.0 billion of net inflows in April. Government bond ETFs had $4.9 billion of net inflows for the month, while corporate and ultra-short maturity exposures also enjoyed healthy flows. On a regional basis, investors favoured euro area, global and US bond ETFs.
Alternative, commodity and multi-asset ETFs all enjoyed net inflows in May.

Important risk information
The value of investments, and the income from them, may fall or rise and investors may get back less than they invested.
Performance figures shown may be calculated in a currency that differs from the currency of the share class that you are invested in. As a result, returns may decrease or increase due to currency fluctuations.
Investments in smaller companies may be more volatile than investments in well-established blue chip companies.
ETF shares can be bought or sold only through a broker. Investing in ETFs entails stockbroker commission and a bid- offer spread which should be considered fully before investing.
Funds investing in fixed interest securities carry the risk of default on repayment and erosion of the capital value of your investment and the level of income may fluctuate. Movements in interest rates are likely to affect the capital value of fixed interest securities. Corporate bonds may provide higher yields but as such may carry greater credit risk increasing the risk of default on repayment and erosion of the capital value of your investment. The level of income may fluctuate and movements in interest rates are likely to affect the capital value of bonds.
The Funds may use derivatives in order to reduce risk or cost and/or generate extra income or growth. The use of derivatives could increase or reduce exposure to underlying assets and result in greater fluctuations of the Fund's net asset value. A derivative is a financial contract whose value is based on the value of a financial asset (such as a share, bond, or currency) or a market index.
Some funds invest in securities which are denominated in different currencies. Movements in currency exchange rates can affect the return of investments.
