US energy independence should insulate domestic chlor-alkali manufacturers from surging feedstock global natural gas costs as the US war in Iran enters its second week and roils markets.
US natural gas prices remain insulated from a global supply crunch even as the war with Iran fuels volatility in oil futures and higher European natural gas prices. Natural gas comprises about 70pc of electrochemical unit (ECU) production costs in the US. An ECU is 1t of chlorine and 1.1 dry metric tonnes (dmt) of caustic soda.
US benchmark Henry Hub natural gas prices have climbed by 4pc after the initial US-Israel joint attacks on Iran on 28 February to settle on Tuesday at $3.07/mmBtu.
But US natural gas futures are unlikely to see near-term volatility unless the conflict is prolonged, analysts said.
"In the short-term, the war would have little to no impact on Henry Hub prices," Baker & O'Brien consultant Kent Bayazitoglu told Argus.
US LNG exporters have little ability to increase volume into the global market because they already operate near capacity. Less-reactive natural gas prices at Henry Hub should widen ECU margins for US producers as caustic soda spot exports trade at $400/dmt fob and higher and polyvinyl chloride prices rebound.
A stable US Gulf coast ECU cost floor could allow producers to be more competitive in the global spot market as other origins face the risk of higher energy prices. European benchmark TTF natural gas prices climbed by as much as 70pc from pre-war levels to $18.94/mmBtu on 9 March before easing to $15.90/mmBtu yesterday — still 43pc higher than pre-war prices.
US Gulf coast spot caustic soda prices were uncompetitive to many destinations outside Latin America before the war in the Mideast Gulf and rallying freight costs following the attacks have further increased delivered prices from the US and other origins. Rising caustic soda prices, though, are not expected to deter import demand as supply options become increasingly limited.
Northeast Asia and Middle East suppliers are virtually locked out of the Mediterranean market with shippers steering clear of the Red Sea, and planned maintenance in the US and Europe should limit spot availability throughout the Atlantic basin through the second quarter.
Mediterranean importers, who have been on the sidelines since January with plentiful inventory, potentially face steeper spot price increases for the next round of buying because of higher freight costs and expected supply limitations in the Atlantic.
