There may be no more LNG left to export, according to Evercore's Sean Morgan.

In a note published on Tuesday, Morgan said LNG prices have hit record highs ahead of the northern hemisphere winter peak season and carrier rates have failed to follow, suggesting there is simply no more gas to move.

"With the [arbitrage] wide open and sufficient vessels to carry LNG to gas-hungry ports of demand, the only explanation is that there is no incremental gas available to carry," he said.
