Stock markets across the world powered higher yesterday, sweeping aside worries about a flagging global economy after the U.S. Federal Reserve said it would remain "patient" in its approach to raising interest rates. The positive results of the Fed's decision were also seen in the Turkish financial markets. Borsa Istanbul's BIST-100 index closed the day at 82.895, increasing 2.57 percent as the U.S. dollar continues to slide against the TL.The dollar was around 2.3140, decreasing 1.01 percent after hitting a historic low of 2.42 per dollar on Tuesday. Speaking to Daily Sabah, economist Taha Meli Arvas said that despite robust numbers in manufacturing and unemployment, the total U.S. employment participation rate is at its lowest percentage in 40 years, which means that of the total number of Americans that can work, only about 62.8 percent are working. "The participation rate is the one major metric that continues to fall in the United States since the 2008 'Great Recession.' Something is broken in the U.S. economy. That something needs to be changed before interest rates continue to rise" said Arvas.France's CAC 40 jumped 2.2 percent to 4,200.83 and Germany's DAX surged 1.9 percent to 9,727.83.

The world's most powerful central bank is edging closer to raising interest rates from record lows given a strengthening U.S. economy. But it will be "patient" in deciding when to do so. That was the message sent Wednesday as the Fed ended a meeting amid heightened expectation about a forthcoming rate increase. At a news conference, Chair Janet Yellen said she foresaw no rate hike in the first quarter of 2015. "With a week to go to Christmas, Santa seems to have finally arrived for global equities," said Stan Shamu, market strategist at IG in Melbourne, Australia.
