"Markets continue to be positive for pension funds, and overall, reported pension deficits are showing a strong improvement from 12 months ago," said Charles Cowling, director at JLT, in a news release. "Indeed, the FTSE 100 is very close to showing an aggregate surplus in its pension funds for the first time in a decade."
"However, crucial for pension funds, is the outlook for interest rates." Mr. Cowling said. "It had been thought likely that the Bank of England's Monetary Policy Committee would raise interest rates at their meeting in May, but that did not materialize. Indeed, two factors suggest that the next rise in interest rates could be some months away yet. There were positive signs on inflation with the latest figures revealing a headline rate of 2.2%, down from 2.3% last month."
Mr. Cowling added: "Secondly, there has been a change announced to the Bank of England's Monetary Policy Committee this month, with Professor Jonathan Haskel set to replace Ian McCafferty from September. Mr. McCafferty has consistently been one of the more hawkish members of the MPC, voting against the majority in favor of raising interest rates."
