European Markets in Holding Pattern Ahead of ECB Decision

European markets stuck to their recent holding pattern Thursday while investors awaited the European Central Bank's policy announcement.

The euro, which has weakened since ECB President Mario Draghi last month suggested that easing measures could be on their way in June, was steady against the dollar at $1.3610.

The central bank is widely expected to cut all its main interest rates at Thursday's meeting, including pushing its deposit rate into negative territory for the first time. Some analysts also expect further action such as steps to boost liquidity or a package of cheap loans to banks.

"For recent euro weakness to extend further after today's meeting, the ECB will likely now have to meet high investor expectations and perhaps even hint that more easing is likely later this year," said Lee Hardman, a currency analyst at Bank of Tokyo-Mitsubishi UFJ.

Investors will also be looking out for signals from Mr. Draghi of future steps--particularly the possibility that the ECB could launch a program of large-scale asset purchases if inflation continues at its current sluggish pace.

Data earlier in the week showed consumer price growth in the currency bloc slowed to just 0.5% annually in May.

A survey conducted by Barclays shows that just over 46% of its clients questioned expect the ECB to cut rates and announce targeted credit easing.

In equity markets, the Stoxx Europe 600 index was little changed in early trade.

Outside the euro zone, London's FTSE 100 slipped 0.2%. The Bank of England also makes its monthly interest rate decision Thursday and is widely expected to keep policy on hold.

In the U.S., S&P 500 futures were little changed, with investors eyeing the government's monthly employment report due Friday, which is expected show nonfarm payroll growth of 210,000.

On Wednesday, data compiled by Automatic Data Processing and Moody's Analytics showed that 179,000 private-sector jobs were added in May, falling short of expectations of a 210,000 increase. Changes in futures don't always accurately predict market moves after the opening bell.

Back in European equity markets, Smith & Nephew shares climbed sharply after Medtronic Inc. was reported by Bloomberg to be considering an offer for the U.K. medical-device maker.

In a further sign of the market for mergers and acquisitions reviving, German household consumer products maker Henkel AG & Co. said is would pay EUR940 million ($1.27 billion) in cash for French company Spotless GroupSAS in a move aimed at strengthening its position in Western Europe.

According to Dealogic data from this week, the volume of global consumer-sector M&A stands at $26.6 billion year-to-date, already marking a robust 89% rise on the same period last year.

Elsewhere, shares in online retailer Asos slumped by more than 40% after issuing a profit warning, saying increased levels of promotional activity have hit margins. Year-to-date, that marks a more than 47% tumble in the stock price.

In commodities markets, gold was down 0.1% at $1,243.40 an ounce, while Brent crude oil was down 0.3% at $108.07 a barrel.
