U.S. stock index futures indicated a flat-to-lower open on Monday, with housing market indicators set to dominate this week after a run of soft economic data.
Data due for release Monday includes the National Association of Homebuilders housing index for May at 10:00 a.m. ET. April housing starts figures are due on Tuesday, followed by existing home sales numbers on Thursday.
But the likely data highlight of the week will be Friday's release of April inflation data, expected to show the headline rate unchanged. The U.S. Federal Reserve will also publish minutes on Wednesday.
The run of soft economic data in the first quarter has now clearly spilled into the second quarter, with some disappointing misses in just the past week in retail sales, producer price inflation data, industrial production and consumer sentiment.
Those misses helped push market expectations for a first Fed rate hike past December and into January, with fewer market players now betting on a September rate increase.
While speaking at the Swedish capital on Monday, Chicago Fed President Charles Evans said the U.S. Federal Reserve could look at a rate hike in June if the economy is strong enough, Reuters said. His speech argued for rates to start rising in early 2016.
Evans told reporters if the Federal Open Market Committee had confidence that inflation was going to move up and that first quarter economic softness was temporary, "you could imagine a case being made for a rate increase in June."

U.S. stocks closed narrowly mixed in choppy trade on Friday, as disappointing data weighed on investor sentiment amid dollar declines and lower bond yields.
The S&P 500 gained 1.6 points to set a second record close for the week, after ending at a high on Thursday. Stocks posted mild gains for the week, with the Nasdaq the best performer.
