I think you misunderstand. I'm not arguing that the US will face a shortfall. The data above show that the US imports less than 25% of its bromine, but are redacted to prevent the public knowing the real amount. Factories in America are unlikely to face shortfalls of bromine.

But unless we have an extra 250 million tonnes of production capacity sitting on the sidelines, which would probably mean more than doubling our total output, we're not going to make up the shortfall for anyone else. We're talking about the majority of (disclosed) global production going offline if Iran could manage it (though again it is not clear that they can or will). China will also probably be using everything that they produce. Europe and the rest of Asia will be left high and dry. It's a win for the US strategy of critical minerals resilience, in some sense, but it's still a problem.

The linked article from USGS says nothing about semiconductor-grade purity bromine, but only about ordinary bromine that is used in the chemical industry.

Semiconductor-grade purity bromine is orders of magnitude more expensive than ordinary bromine and the vast majority of bromine producers do not make it.

The USGS article provides no evidence that such bromine is made in USA. I would rather expect Japan to be a producer, not USA, because for many semiconductor-grade purity chemical substances there are major producers in Japan.

Korea does not like to depend on imports from Japan, so I would not be surprised if there was a Japanese source of pure bromine but Korea prefers to import it from Israel. If this were true, they could still switch suppliers in case of a shortage.

Semiconductor-manufacturing grade hydrogen bromide IS made in the US, and we do sell it to Korea (and Japan, and Taiwan...)

The issue is chip production in Korea and possibly Taiwan. And that's where vast amounts of US chip inventory comes from. How to buildout AI capacity if can't source memory chips? This exposes another risk to the high AI valuations which are underpinning market valuations.

The article is timely as it suggests yet another unconsidered risk factor of this war - USA could destroy its own stock market. Or Iran could accelerate that with one missile. I like to think the US military know this hence obsession with missile destruction but it is reasonable based on recent behaviour to assume that the MAGA overlords can't even spell bromine nevermind understand the risk.
