UK stocks hold gains despite complex new forward guidance from BoE

- Carney revamps forward guidance- BoE focusing on 'spare capacity' in economy- Bank Rate to rise only gradually when tightening is needed- Morrisons in buyout talks with private-equity firmstechMARK 2,824.49 -0.42%FTSE 100 6,683.78 +0.17%FTSE 250 16,060.03 -0.11%UK stocks held on to small gains on Wednesday as investors digested a revamped forward guidance strategy put forward by Bank of England Governor Mark Carney alongside the quarterly Inflation Report.Though the reaction in equity markets was relatively calm, analysts said that the new plan, which focuses on a much broader range of economic variables, has made the outlook for monetary policy more complex."The market has put a premium on the uncertainty that this has created, despite the Bank's attempt to dampen expectations of higher rates. In short, the Bank is digging [a hole], but with an even bigger shovel," said Simon Smith, Head of Research at FxPro.The FTSE 100, which rose to a high of 6,708.17 ahead of Carney's comments, had pared gains slightly but was still trading 0.2% higher at 6,684 by midday. The index jumped 1.2% on Tuesday to 6,672.66 - its highest finish since January 23rd - after new Federal Reserve Chair Janet Yellen expressed her commitment to continuing to scale back stimulus in "measured steps" after a "broad improvement" in the labour market.Asian markets rose overnight after a higher-than-expected trade surplus in China as exports rose by more than anticipated in January. The trade balance of $31.86bn, surprising analysts who had expected a slight decline from the $25.64bn surplus registered in December.Meanwhile, the US House of Representatives has passed an increase in the government's borrowing limit. The House voted 221-201 to waive the $17.2trn debt limit for just over a year, after Republicans gave up on their attempt to win concessions from the Democrats in return.Carney redesigns forward guidanceCarney revised his initial forward guidance plan, which attempted to link monetary policy to the unemployment rate, just six months after its creation given that joblessness has fallen much faster than many had predicted. In contrast, the new guidance is now focused on a range of indicators which are aimed at reducing the amount of excess slack in the economy.He stressed that if and when the times comes that the economy can sustain higher interest rates, the Bank Rate will then rise only gradually and any increase in rates will be limited.Chief European Economist Jonathan Loynes from Capital Economics said that the new guidance from the BoE shifts the focus back to the benign outlook for inflation and "should therefore ensure that monetary policy remains very loose for some considerable time yet".However, he said that the revised guidance "lacks the simplicity" of the initial plan given that so-called 'spare capacity' is an "even more unpredictable, and much less observable, economic concept" than unemployment.WM Morrison founders considering private-equity buyoutWM Morrison was in focus after Bloomberg said that its founding family is considering taking the supermarket group private.
