"The real problems are going to start when they start back up," a market source said. "You have to empty the whole system or pipes will burst. It will take at least two weeks for all of them to start up, and that's without problems."

Sources said the freeze, which brought bitter cold to a region where infrastructure is not built for sustained sub-freezing temperatures, was worse than even the most vicious hurricanes, including Harvey which drowned southeast Texas with unprecedented flooding in 2017.

"It's affecting transportation, railroads, trucking – even if you can make the product, you can't get it delivered," another source said. "It's going to have a major impact on all these plants on the Gulf Coast. It's at least as bad as a hurricane and it's more widespread."

Market sources expect prices for polymers and some olefins, which had already reached record highs amid tight supply as producers navigated the coronavirus pandemic, to spike further on the freeze-related disruptions and uncertainty.

Here is a rundown of confirmed fallout from the freeze:
