Japan's government bonds increased pushing 10-year and 20-year yields to its lowest levels in almost ten years on Tuesday after the Bank of Japan's governor Haruhiko Kuroda said he will take steps to influence the so-called yield curve through purchases of long-term assets. 10-year benchmark yields hit its lowest level since June 2003 at 0.525% and 20-year rate closed at 1.46% after it touched a 10-year low at 1.41.
