After opening up of the Interconnector, the liberalized UK natural gas market and the regulated Continental gas markets became physically integrated. The oil-linked Continental gas price became dominant, due to both the large volume of the Continental market and to the fact that the significant call options embedded in the complex take-or-pay contracts make these contracts the marginal source of supply. However, in an interim period - after deregulation of the UK gas market (1995) and the opening up of the Interconnector (1998) - the UK gas market had neither government price regulation nor a physical Continental gas linkage. We use this period - which for natural gas markets displays an unusual combination of deregulation and autarky - as a natural experiment to explore if decoupling of natural gas prices from prices of other energy commodities, such as oil and electricity, took place. Using monthly price data, we find a highly integrated market where wholesale demand seems to be for energy rather than a specific energy source.
