Two opposing natural gas pricing systems have coexisted for the last two decades. On the one hand, there is traditional oil-linked pricing, used in pipeline gas imports by Continental European countries and in LNG imports by the countries in Far East. The other is the system led by futures exchanges in deregulated, competitive markets largely in the UK and the US.

In the first half of 2009, natural gas prices set by oil-linked formulas in Continental Europe were twice as high as market prices at the Henry Hub or the NBP (National Balancing Point). Because of this, oil-indexed Russian imports fell sharply to their contract limits and discussions on de-linking gas pricing started once again. This time, the most vocal were major European gas companies which had to buy expensive oil-indexed natural gas. The same situation is developing in Asia between oil-indexed LNG and the one based on market gas prices. Even traditional oil-indexed LNG buyers in the Far East are insisting on a partial linkage to Henry Hub prices.

Gas pricing formulas in Continental Europe are typically indexed to light and heavy fuel oil. In the 1970s when oil was used to fuel many power stations and large-scale industrial plants, the logic of natural gas directly replacing oil products made sense, but markets have changed significantly over the past two decades. Crude and oil products have been increasingly forced out of power generation and other stationary uses both by price and by policy. Instead, oil is overwhelmingly used as transportation fuel. Therefore, the logic of oil as the replacement comparator for gas is no longer supported by reality.

The financial crisis and economic downturn starting in September 2008 had a profound impact on economic activities including natural gas demand. Global gas demand fell sharply between 2008 and 2009 and for the first time in decades, electricity demand also decreased. With weak electricity markets, fuel competition between spot priced natural gas and coal took place at many power plants.
