The hype surrounding the historic summit Friday between U.S. President Donald Trump and Russian President Vladimir Putin makes clear that Russia — even under global sanctions — remains a powerhouse in the energy market.

Oil prices could swing wildly depending on how the summit goes. Any movement toward a peace deal on Russia’s war in Ukraine could lead to crude benchmarks dropping below $60 a barrel, some analysts say. If the talks end with the U.S. imposing stricter sanctions, prices could top $80 a barrel.
