From Fortune:

Boeing shares tumbled 9% as fallout from a 737 Max inflight blowout shook the manufacturer, wiping $13.5 billion of its market cap. Wall Street remained steady, with S&P up 0.2%. Crude prices tumbled, and Delta, JPMorgan Chase, and inflation reports are expected later this week.

Boeing and other aviation stocks tumbled ahead of the opening bell Monday on news of grounded Boeing 737 Max 9 aircraft following an inflight blowout. The Federal Aviation Authority ordered the grounding of 171 of the 218 Max 9s in operation for inspection.

The incident is the latest of the troubled history of Boeing’s Max airplanes and will likely cause additional consequences for Boeing, Spirit AeroSystems, and Alaska Air Group.

Markets in different parts of the world are currently reacting to this, though the overall effect isn’t overly negative.

In addition to news of grounded airplanes, the government’s report on inflation and investigations on the mishap contributed to a shaky start to the trading week on Monday.
