Natural-gas prices are spiking around the world

ACROSS THE world, a natural-gas shortage is starting to bite. Prices of power in Germany and France have soared by around 40% in the past two weeks. In many countries, including and Spain, governments are rushing through emergency measures to protect consumers. Factories are being temporarily switched off, from aluminium smelters in Mexico to fertiliser plants in Britain. Markets are frantic. One trader says it is like the global financial crisis for commodities. Even in America, the world’s biggest natural-gas producer, lobby groups are calling on the government to limit exports of liquefied natural gas (LNG), the price of which has climbed to $25 per million British thermal units (mBTU), up by two-thirds in the past month.In one sense , with a mosaic of factors from geopolitics to precautionary hoarding in Asia sending prices higher. Viewed from a different perspective, however, its causes are simple: an energy market with only thin safety buffers has become acutely sensitive to disruptions. And subdued investment in fossil fuels may mean higher volatility is here to stay.
