A situation of chaos and economic recession could cause the world economy and bitcoin die. We all know that if the world economy is currently very dependent from china, so whatever happens with china influenced bitcoin.
I think it would be the opposite. If the global markets started to crash, mainly the banking sector, bitcoin would go down with them, but then people would start seeking something that doesn't depend on banks. Something out of the system. They would turn to things that survive price wars, unemployment, wars, like gold, jewelry, art, and bitcoin.
