Reserve Bank of India Governor Urjit Patel may consider resigning from his post given a breakdown in relations with the government, TV channels reported on Wednesday, sparking a sell-off in the rupee and bonds. Television channels CNBC-TV18 and ET Now cited sources as saying that Patel could quit. The RBI and the finance ministry declined to comment. The government has invoked never-before-used powers under the RBI Act that allow it to issue directions to the central bank governor on matters of public interest, the Economic Times newspaper reported.
