This is a non issue. It’s all about supply/demand. Crude dropped to under $17 per barrel in (I think) 1998. There was no catastrophe then and there will be non if it happens again.
That was the result of an EIA forecast that predicted a worldwide glut of oil, but 'forgot' to factor in Asian demand.
Driling stopped completely in the area where I primarily (Rig count: zero) for the first time since oil was discovered in the early '50s.
I think the difference is that in 1998 the drillers and extraction were not financed by a panoply risky loans and those loans in turn were not sold on as good rated investments.
