The CMA is suggested the energy competition is weakening. The Competition and Markets Authority (CMA) has offered the first clues as to where its energy sector investigation will focus. Although no conclusions have been reached, the investigators compared the average standard variable tariff against forward-looking costs in its initial work. It pointed out in its statement that the gap between average tariffs and underlying costs appears to widen in particular since 2009. “We will seek to assess to what extent the ‘rockets and feathers hypothesis’ [where prices rise quickly but fall slowly] applies in practice,” the CMA said.
