Indian government bonds fell on Tuesday, with the benchmark 10-year note set for a sixth straight day of losses after Washington and Tehran launched fresh attacks in the Gulf, pushing oil prices higher and clouding India's macro outlook. The U.S. and Iran renewed attacks on Monday as they battled for control of the key waterway with duelling maritime blockades, derailing a fragile truce. Oil climbed 6% to $114 a barrel on Monday before easing more than 1% in Asian trading, while the 10-year U.S. Treasury yield rose nearly 7 basis points after the attacks.
