(Reuters) - U.S. stocks were set to open modestly lower on Monday as investors digested Friday's strong jobs data, which increased expectations that the Federal Reserve could raise interest rates as soon as September.
Stronger-than-expected jobs data for May and a pickup in wages were the latest signs of improved momentum in the economy, prompting expectations of a rate hike sooner rather than later.
While the Fed is broadly expected to raise interest rates this year, the timing of the move has kept the market on tenterhooks.
Wall Street's top banks said they expect the Fed to begin raising rates in September, followed by another increase before the end of the year, according to a Reuters poll.
"I think we'll see a lot more back and forth for a while," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
"There are concerns that the Fed will be more aggressive regarding the timing of the hike and a steeper hike following the first one."
More sales of German government bonds weighed on European stock markets, while the dollar retreated after a report - later denied - that President Barack Obama had expressed concern over its strength after a year-long rally.
Higher bond yields make stocks less attractive. U.S. benchmark Treasury debt yields on Friday posted their best weekly performance in two years after strong jobs data, while German bunds hit 8-year highs.
