Futures for the Dow Jones Industrial Average and the S&P 500 each rose about 0.2% before the bell.

British Airways canceled dozens of flights Friday, blaming computer problems for disrupting plans for thousands of passengers at the start of a busy holiday weekend — a rocky kickoff to the summer travel season in Europe.

Commerce Secretary Gina Raimondo and her Chinese counterpart, Wang Wentao, expressed concern Thursday about policies of each other's governments following Chinese raids on consulting firms and U.S. curbs on exports of semiconductor technology, their governments said.

Days from a deadline, President Joe Biden and House Speaker Kevin McCarthy are narrowing in on a two-year budget deal aiming to curb federal deficits in exchange for lifting the nation's debt ceiling and staving off an economically devastating government default.

The Democratic president and Republican speaker hope to strike a budget compromise this weekend.

Phoenix retiree Saundra Cole has been watching the news about the debt limit negotiations in Washington with dismay — and limiting her air conditioning use to save money just in case her monthly Social Security check is delayed due to a default.

As it marks its 25th anniversary Wednesday, the European Central Bank is readying a proposed design for a digital version of the euro, responding to pressure from developing technology that could change how money is used over the bank's next decades.

Debt ceiling negotiations are locked on a classic problem that has vexed, divided and disrupted Washington before: Republicans led by House Speaker Kevin McCarthy want to roll back federal government spending, while President Joe Biden and other Democrats do not.

Time is short to strike a deal before a deadline as soon as June 1, when the Treasury says the government risks running out of cash to pay its bills. Negotiators are expected to convene Wednesday for another round of talks as frustration mounts.
