The Breakwave Tanker Shipping ETF (BWET) gained roughly 3,600% year to date through Sept. 11, according to Morningstar, making it the best-performing non-leveraged U.S. fund. A newer account instead described BWET as a dry bulk shipping ETF and reported a 1,168% rise from February 2026 after U.S. and Israeli strikes on Iran; this appears to reflect a naming or measurement discrepancy. BWET tracks tanker transportation prices rather than crude oil, and its performance has been driven by Strait of Hormuz and other Middle East shipping disruptions, vessel shortages, insurance costs and longer routes. Freight rates could reverse quickly if tensions ease, while higher energy and shipping costs are adding to inflation and supply-chain pressure.
