Daily freight rates to ship liquefied natural gas are at a record high, and prices are expected to climb further as winter approaches. Spot rates for ships commonly used to transport LNG are at $450,000 this week, a sixfold increase since the start of this year, according to the Baltic Exchange a London-based, freight-information provider. Brokers expect daily rates along main trade routes, including one from Texas to Northern Europe, to climb to $500,000 this month as the demand to charter ships remains high.
