By Chikako Mogi    Anchalee Worrachate U.S. currency boosted as 30-year bond yield climbs above 3% Fed to weigh stronger currency in rate review: Credit Agricole   The dollar advanced for a fourth day on bets that higher spending under Donald Trump’s administration will boost economic growth and inflation, convincing the Federal Reserve to raise U.S. interest rates. A gauge of the U.S. currency climbed to the highest since February, extending its biggest weekly gain in five years, as President-elect Trump unveiled key administrative appointments in preparation for taking power in January. Thirty-year Treasury yields rose above 3 percent for the first time since January on expectations inflation will accelerate. While higher-yielding assets advanced, the yen dropped to a five-month low against the dollar. Japan’s better-than-forecast third-quarter economic growth added to speculation that global expansion will pick up, damping demand for the yen as a haven.   “The Trump win is playing out as a major boost for the dollar,” said Valentin Marinov, head of Group-of-10 currency strategy at Credit Agricole SA’s corporate- and investment-banking unit in London. “The key risk to the rally remains the Fed’s willingness to tolerate further aggressive tightening in the U.S. financial conditions. Time and time again, too-rapid dollar gains were standing in the way of aggressive Fed hikes.” The Bloomberg Dollar Spot Index, which tracks the U.S. currency against 10 major peers, rose 0.8 percent to the highest since Feb. 3 as of 6:30 a.m. in New York. The gauge surged 2.8 percent last week, the most since September 2011.
