"Next week could be one of the most important weeks of the whole year," said Marc Chandler, head of foreign exchange strategy at Brown Brothers Harriman . U.S markets are closed for the Thanksgiving holiday Thursday, and stocks trade in a shortened session Friday. So by Wednesday the market focus was already on the coming week, and for investors worldwide, it's a busy one. First on Monday, the IMF is expected to grant China's yuan reserve currency status. Next Friday's U.S. November jobs report is the highlight of the week Fed Chair Janet Yellen speaks not once but twice next week Oil will also be big in the coming week, with OPEC's meeting in Vienna next Friday. Iran would want to clear the way for its own oil to come back on the market, once sanctions are lifted. The currency market Wednesday was already previewing next week's central bank activity. News reports of a more aggressive ECB sent the euro lower, to the $1.05 range and the dollar index moved above 100 before settling back below it. ECB President Mario Draghi speaks after the meeting Thursday, but he also travels to New York where he will be speaking to the Economic Club of New York on Friday. The European Central Bank is expected to possibly add to its quantitative easing program and extend it to different types of debt. The ECB could also cut its already negative deposit rate by another 10 basis points. "They are buying 60 billion euros [$64 billion] worth a month, and they possibly get to 80 or 90 billion euros," said Chandler. As the euro fell Wednesday, the yield gap between the two-year German bund and U.S. Treasury was the widest in nine years. The two-year bund yield fell to negative 0.42, reaching the widest spread with the U.S. two year in nine years.
