A 1,300% Rally Turns a Tiny Shipping ETF Into an Iran War Gauge

Every twist in the Iran conflict — every ceasefire bet, every missile strike, every shift in tanker traffic — shows up almost instantly in a $65 million exchange-traded fund that most investors have never heard of.

The Breakwave Tanker Shipping ETF plunged roughly 13% on market open Wednesday after Iran said it would allow safe passage through the strait. Within hours, it snapped back — surging after Iran’s Revolutionary Guard halted tanker traffic through the Strait of Hormuz once again in response to Israeli strikes on Lebanon.
