European markets were mixed Monday and the euro weakened as investors waited to see what would happen next in Spain after Prime Minister Mariano Rajoy outlined measures to take control of Catalonia.

U.S. futures were pointing to a positive opening, with the Dow Jones Industrial Average mini futures up 0.11% and S&P 500 mini futures up 0.09%.

Spain's Ibex 35 was the biggest faller in Europe, losing 34.4 points or 0.35% to 10,18730. Meanwhile the euro dipped 0.3% to $1.1743, the weakest in two weeks.

On Saturday Prime Minister Mariono Rajoy unveiled a number of measures, including a plan to clear out the entire separatist regime in Barcelona and take control of key institutions in the media and police, in response to the region's disputed referendum on independence on Oct. 1. The Catalonian parliament will meet on Thursday to decide on how to respond to Rajoy's measures. 

The Spanish senate will meet on Friday and is expected to sign off on the measures that will likely see Catalan's President Carles Puigdemont and his cabinet fired. Spain's chief prosecutor said that Puigdemont could face 30 years in jail if he declares independence. 

London's FTSE 100 was marked 0.14% higher at 7,533.86. Prime Minister Theresa May will make a statement to parliament on the progress of Brexit. Business groups over the weekend piled pressure on the U.K. government to outline details of a transitional deal, that would see the country stay in the single market for a specified amount of time.

"Agreement [on a transition] is needed as soon as possible, as companies are preparing to make serious decisions at the start of 2018, which will have consequences for jobs and investment in the UK," said a letter from business lobby groups to the Brexit Secretary David Davis.

The pound was 0.12% down against the greenback at $1.31749.

Japanese equities continued their winning streak on Monday after a landslide victory for Prime Minister Shinzo Abe sent the Nikkei up more than 1%.

Japan's Nikkei and Topix led the region, gaining 1.11% and 0.84% respectively Monday on Abe's victory, which will ensure loosened monetary policy will continue and clearing a hurdle for Abe's long-term goal to amend the constitution.

This was the 15th straight day for gains for the Nikkei, marking its longest winning streak on record. The Topix rise marked its 11th straight day of gains.

The Hang Seng was up 0.67% and the Shanghai Composite was up just 0.02%.
