“Up 3,600%, this freight fund has posted the biggest gains of all on Iran war oil shock”

What actually happened

BWET, an ETF that tracks the futures cost of shipping crude by tanker rather than the price of crude itself, has posted an extreme year-to-date gain as the U.S.-Iran conflict, Houthi attacks and a Saudi pipeline shutdown disrupt tanker routes through the Strait of Hormuz and Red Sea. Sourced experts in the article say the surge also reflects tariff-driven rerouting and drought-hit ports (Panama, Europe) that have squeezed the global vessel supply independent of the war.

Key facts

• The Breakwave Tanker Shipping ETF is up roughly 3,600% year-to-date as of early September, according to Morningstar data through Sept. 11, making it the best-performing non-levered fund in the U.S. Yahoo Finance's own YTD figure for the same period shows a comparable but distinct 3,274% total return, underscoring how date-cutoff sensitive these numbers are.
• The most important detail about BWET is that it tracks the price of shipping oil, rather than underlying crude oil prices. "It has very little to do with the oil price itself or its actual volume and depends mainly on geopolitics," Murillo said.
• Year over year, rates on the Middle East oil tanker routes it tracks are up close to 500%, according to BWET's most recent biweekly tanker report on Sept. 8, a fraction of the fund's 3,600% headline number, reflecting the leverage-like torque of a low-priced, high-beta ETF.
• It is not just the Iran war that has caused this freight trade to boom: scrambling of traditional trade routes due to tariffs and widespread drought, with low water levels plaguing ports in Panama and in Europe, have created an unprecedented shortage of ships.
• Earlier reporting on this same fund tracked its rise in stages: BWET was "up about 243% year to date" before later hitting a year-to-date gain to 1,659%, showing this is an escalating trend across months, not a single headline spike.

What to watch for

• BWET's own tanker report already flags a coming reversal: a swelling newbuild orderbook that will eventually create a supply glut and "an industry downcycle" once ~200 vessels under construction hit the water in 18-36 months.
• Watch whether follow-up coverage keeps crediting "the Iran war" alone, or starts acknowledging the tariff- and drought-driven vessel shortage that sourced experts say is doing much of the work.
• Watch the fund's tiny, high-beta price base (beta 5.56, 3.50% expense ratio) next time a headline percentage looks implausible: small absolute moves in illiquid, low-NAV instruments produce outsized percentage swings.
