LONDON (Reuters) - The International Energy Agency (IEA) is set to forecast global supplies of natural gas will rise faster than demand in coming years, the Financial Times newspaper reported on Thursday.

"Global gas markets have evolved from a seller's market, driven by tight supply and demand, to a buyer's market as demand weakens while new supply comes onstream," the IEA says in a draft report of it World Energy Outlook, to be published November 10, according to the FT.
