Indian government bonds traded flat on Monday after last week's rally as higher oil prices offset support from softer U.S. data, while traders looked ahead to July inflation data for India and the United States for further direction.
The benchmark 6.94% 2036 bond ended little changed at 6.7643% on Monday.
