NEW YORK (MarketWatch) -- Treasury prices advanced Monday, sending yields lower, as concerns about a global economic recession boosted safe-haven demand for government debt. Ten-year Treasury note yields fell 2 basis points to stand at 3.723%. "Treasurys are higher to open the week as global equities register their disappointment with the lack of concrete action from the weekend G20 meeting -- more "too little, too late" from policymakers," said analysts at Action Economics. In addition, "economic woes remain a major concern to investors," they said.
