TOKYO, March 16 (Reuters) - Japanese government bond (JGB) yields fell on Tuesday, tracking a slide in U.S. in Treasuries as investors await the outcome of this week’s Federal Reserve meeting. The yields’ decline also comes amid the Ministry of Finance’s liquidity-enhancing auction that was in line with investors’ expectations, a market participant said. A bid-to-cover ratio for the sale was 3.36, below 5.06 at the previous auction. The ministry sold off-the-run JGBs with remaining maturities of 5 years to 15.5 years. The 10-year JGB yield fell one basis point to 0.095%. The 20-year JGB yield also fell one basis point to 0.48%. The 30-year JGB yield fell one basis point to 0.665% and the 40-year JGB yield fell 0.5 basis point to 0.71%. The five-year yield also fell one basis point to minus 0.1%. The two-year JGB yield fell one basis point to minus 0.15%. Benchmark 10-year JGB futures rose 0.12 points to 151.19.
