Referring to the MA (History) degree of the RBI chief, Vyas said he hoped that the RBI governor did not make the central bank itself history.
"The New RBI Governor Das's educational qualification is MA (History). Hope and Pray he doesn't make RBI also a History. May God Bless the New Arrival!!" Vyas tweeted.
Vyas, who was health and family welfare minister in Gujarat till 2012, has been sidelined in the party now. He lost the Assembly elections in 2012 and 2017.
Das, a former bureaucrat, was named the RBI governor Tuesday following Urjit Patel's sudden exit.
Besides post graduation in history, Das has done an advanced financial management course from Indian Institute of Management, Bangalore and another in development banking and institutional credit from Pune's National Institute of Bank Management.
He also got in-service professional training in financial management in Institute Public Enterprises and did a diploma in basic project management from Administrative Staff College of India, according to reports.
Das has been the target of ridicule in social media over his educational qualifications vis as vis predecessors Patel and Raghuram Rajan who had doctorates in economics.
