In Europe, the Stoxx 600 Index finished the day with a 0.3 per cent gain from the previous close. France's CAC 40 Index added 0.3 per cent, while the UK's FTSE 100 Index rose 0.6 per cent, and Germany's DAX Index climbed 0.7 per cent.
The European Central Bank upgraded its forecast for economic growth in the eurozone this year to 2.2 per cent, which would be the fastest pace in a decade. ECB policy makers kept the central bank's interest rates unchanged and flagged that its asset purchase program will run until December, "or beyond, if necessary."
"The economic expansion, which accelerated more than expected in the first half of 2017, continues to be solid and broad-based across countries and sectors," ECB President Mario Draghi told reporters in Frankfurt.
"At the same time, the recent volatility in the exchange rate represents a source of uncertainty which requires monitoring with regard to its possible implications for the medium-term outlook for price stability," Draghi said.
The euro gained 0.7 per cent to US$1.2002.
"Equities are reacting more to the stronger economy than the currency rate-a lot of companies will be able to cope with a euro at US$1.20," Simon Wiersma, an investment manager at ING Bank in Amsterdam, told Bloomberg. "I can cope with it. Equities can still rise from here, though if the euro trends toward US$1.25, it will become a bigger concern."
