(Alliance News) -Â In another volatile session, the FTSE 100 managed to end Tuesday higher as the latest stimulus measure from the US Federal Reserve appeared to soothe markets.
"Just as investors were starting to seriously flag once again, the Fed actually managed to pull-off a market-boosting intervention after a string of false dawns," said Connor Campbell at Spreadex.
"The central bank announced on Tuesday that it would be launching a Commercial Paper Funding Facility, ie a way for it to buy up short-term debt issued by struggling companies seeking to raise cash," said Campbell.
"It seems that, after being sceptical of the Fed's rate cuts and trillion-dollar stimulus injections, the creation of this new special credit facility was the kind of thing investors were hoping for."
The FTSE 100 index closed up 143.82 points, or 2.8%, at 5,294.90, rebounding in the afternoon after trading below 5,000 earlier in Tuesday's session.

The Fed unveiled a new credit facility to help households and business stay afloat as the coronavirus pandemic threatens to undermine the world's largest economy.
The program, authorised by the US Treasury, is aimed at commercial paper, which finances things like auto loans and home mortgages, a market that "has been under considerable strain in recent days as businesses and households face greater uncertainty in light of the coronavirus outbreak".
"By ensuring the smooth functioning of this market, particularly in times of strain, the Federal Reserve is providing credit that will support families, businesses, and jobs across the economy," the Fed said in a statement.
Stocks in New York were in the green at the London equities close, with the DJIA up 3.1%, the S&P 500 index up 4.3%, and the Nasdaq Composite up 4.4%.
