The Federal Reserve (Fed) has kept interest rates unchanged, leaving the benchmark federal funds rate at between 3.50% and 3.75%, while oil hit a 4-year high overnight. The 10-year Treasury bond yield, the key benchmark for U.S. government borrowing, was traded at 4.410%. The Fed also saw the highest level of dissent since 1992, with three officials voting against the inclusion of an easing bias in the statement, suggesting that the next move from the U.K. central bank may be to lower interest rates. Meanwhile, Brent crude futures hit $126 a barrel, before paring gains to $121.84 per barrel, up 3.4% and U.W. Texas.
