RE: OppurtunityIf there is an arbitrage opportunity to make money because of this discrepancy, you can bet that the pros will be all over this and this gap would shrink. It’s either the WTI price is manipulated downward or the Brent price is being artificially supported at a higher price or both. The HBP ETFs are based on WTI prices. Are there any ETFs based on Brent prices? If there is, this could be a good opportunity to arbitrage by buying one and sell the other.
