Traders pile into bullish copper options as output cuts loom

Copper jumped the most in more than 16 months on potential supply tightness after news that Chinese smelters discussed potential production cuts aimed at coping with a plunge in processing margins.

With traders sticking to their guns on the Federal Reserve’s rate-cut wagers after a slightly hot February inflation print earlier this week, the outsized move in copper is more of “a bet on the Fed rate action and the dollar weakness. We see aggressive buying on Comex, both outright and options,” said Xiaoyu Zhu, a trader at StoneX Financial Inc

The news of the smelter production cut served as “a catalyst” in the metal’s rally Wednesday and wasn’t surprising after the drop in margins, he said.

Smelters in China, the world’s top refined metal producer and consumer, are facing a crisis after so-called treatment and refining charges — the amount they’re paid to convert concentrate into metal — collapsed. That’s prompted talk of possible output cuts at smelters, which are highly dependent on imported raw materials. The plunge in spot processing fees has been driven by a slew of supply setbacks in the mining industry.

The biggest trade was a $15 million investment in December $4.25/$4.75 call spreads, with futures for that month trading around $4.086 per pound. There was also widespread buying in bullish spreads across April and May options.
