Staggering crisis in Puerto Rico; Saudi women allowed to drive; Trade tensions flare with Canada

What's the role of today's CEO -- besides running their own company? Barely a week goes by without a CEO taking a stand on a controversial issue.

Profitable Moment  Microsoft's Nadella: CEOs must have principles What's the role of today's CEO -- besides running their own company? Barely a week goes by without a CEO taking a stand on the controversial issue de jour; the latest being the row over American football players protesting by kneeling during the national anthem, and President Trump calling them "sons of bitches" who should be fired. Satya Nadella has been the CEO of Microsoft for three years. When he got the job, he was surprised at the range of non-tech issues he had to have official opinions about. "No CEO can just say I'm somehow not impacted by what's happening in society," Nadella told me. Nadella and others at Microsoft have been very critical about the Trump administration's travel ban against Muslim countries, the transgender bathroom battle, and the change in immigration rules that will hurt "Dreamers."   All of this fits into Nadella's belief that true leaders must celebrate "diversity and inclusion." Nadella outlines this in his new book "Hit Refresh."  When I pushed him to talk about how that plays out in practice, Nadella told me CEOs "need to have a set of principles" that could help protect existing values. Of course, knowing when not to get involved is just as tricky. Nadella is well aware that he and other business leaders aren't elected officials. "We're CEOs of companies. For us to act as if we're in the political arena would also be a mistake," he said. Still, it is refreshing to meet a CEO that has thought through these issues, is prepared to take a stand and has the road map (or moral compass) to guide him. No wonder Microsoft is doing so well. It has a leader that knows what he is doing, where he is going and, crucially, why. -Richard.Quest@cnn.com  What's new... what's next By Matt Egan, Julia Horowitz and Paul R. La Monica of CNNMoney 1. Crisis in Puerto Rico after Hurricane Maria Hurricane Maria could cost Puerto Rico between $45 billion and $95 billion, according to one estimate. That's a staggering price tag -- especially considering the upper end of that range is comparable to a year's worth of economic output from the U.S. territory. Citizens are also facing a host of immediate problems, from cash shortages to sweltering, overflowing airports. Much of the region's communications infrastructure remains offline. Once rebuilding begins, it will be up to a mix of public and private groups to pick up the pieces. 2. Is Trump starting a trade war with Canada? Everyone knows Trump has serious gripes with China and Mexico on trade. But tensions are now flaring with Canada, America's No. 2 trade partner. The Trump administration plans to slap a 220% tariff on a jetliner made by Canada's Bombardier. The tariff is a big win for Boeing, but could force Canada to retaliate. U.S.-Canada trade spats already exist over dairy products and paper. And Canada has a history of playing hardball on trade. The Boeing-Bombardier battle is already casting a shadow over ongoing talks to renegotiate NAFTA.  3. U.S. cranks up the pressure on North Korea The Trump administration is cracking down on North Korean banks in the hopes that more financial pressure will dissuade Kim Jong Un from further ramping up the nation's arsenal of nuclear weapons. U.S. Treasury Secretary Steven Mnuchin announced the sanctions after President Trump issued a "final warning" to North Korea -- and nations like China who trade with Pyongyang. But will Beijing listen? Beijing bought coal from North Korea in August -- even though China's goverment said earlier this year that it would no longer do so. 4. Saudi women finally are allowed to drive The ban on women driving is set to be lifted in Saudi Arabia next year. There are hopes that more women will now take part in the Saudi workforce. That could boost the kingdom's economy and reduce the high level of gender inequality. But it could hurt demand for the country's 1.4 million chauffeurs. And it may be a mixed bag for Uber and its Middle Eastern rival Careem, who have benefited from the ban since some women can't afford private drivers. Still, Uber and Careem may now be able to recruit more women as drivers. 5. Quick Takes: Equifax CEO exits suddenly.
