After a tentative start, stocks rallied on Wednesday afternoon on the back of some upbeat comments from Ben Bernanke, the Chairman of the US Federal Reserve. Meanwhile, markets gave a rather muted reaction to the minutes of the latest policy-making meeting in the UK.Bernanke, speaking on the second day of the Fed's semi-annual policy report to Congress, said that he does not expect the US economy to slip back into recession. European markets were initially dampened on Tuesday after Bernanke failed to hint at injecting extra stimulus in the near term but said that the central bank was ready to act.Seven out of the nine policy makers at the Bank of England (BoE) voted in favour of increasing the asset purchase programme by £50bn to £375bn at the last meeting, while the Monetary Policy Committee (MPC) were unanimous in their decision to maintain the Bank Rate at 0.5%. However, the MPC said that new initiatives, such as the BoE's Funding for Lending Scheme (FLS), which offers cheap funding to banks to encourage lending, could make a case for an interest-rate cut in the future. Analyst Philip Shaw from Investec said: "Overall we suspect that QE will remain the authorities' principal stimulus weapon and that the MPC will look through the volatility of the economic data (very weak in Q2, stronger in Q3) and sanction another £50bn of asset purchases later during the year." In other news, UK unemployment fell by 65,000 to 2.58m in the three months to May, according to the Office for National Statistics. The jobless rate dropped from 8.3% to 8.1%, better than the consensus estimate of 8.2%. Nevertheless, the number of people claiming jobless benefits rose by more than expected.
