NEW YORK (TheStreet) -- European stock markets are higher and U.S. stock index futures are signaling a modestly higher open after yesterday's jitters. And this morning, we have seen a continuation of the global bond sell off pushing yields higher. The crude price also climbed overnight to its highest price in 2015 and heading towards $62 a barrel, as the commodity continued on its snap-back. Greece made the markets nervous yesterday when officials expressed pessimism on the state of the negotiations between it and the International Monetary Fund and the European Union.
