Fitch warns of potential credit impact of 737 Max crashes

Boeing, its suppliers and some weaker airline credits could come under credit ratings pressure this year if complex safety problems are identified with the 737 Max, Fitch Ratings warns.The agency says in a research note that there are several possible scenarios from the recent crashes of 737 Max 8s operated by Ethiopian Airlines and Lion Air that have led to the grounding of the world's 737 Max fleet, but stressed that it is not taking rating action yet.Most concerning would be a harsh scenario including a systemic issue with the aircraft leading to lengthy groundings, material delivery delays, significant order cancellations and negative public sentiment toward the Max .
