I don't think you have thought enough about how much physical infrastructure would be required to launch a nuke. There are 3 ways to deliver a 100kt warhead: Silo launch, sub launch or dropped from a plane. All of those would require hundreds of people who would be impossible to keep quiet after the effect, especially since the intelligence services of every nation on the planet would be looking for them.
But like, if you are writing a story where you are willing to create such an unrealistic scenario in the first place, it really doesn't matter what would happen to oil prices in reality. Just say it does if that works best.
