We should celebrate Moody's upgrade by holding a midnight ceremony in Central Hall of Parliament and damn Standard and Poor. — Yashwant Sinha (@YashwantSinha) 1510904509000

NEW DELHI: Former finance minister and senior BJP leader Yashwant Sinha on Friday took a dig at the Centre after international rating agency Moody's upgraded India's rating.Sinha indirectly reminded the government that rating agency Standard & Poor's has kept India at the lowest investment grade for a decade, and slammed the government's celebration of the country's upgraded rating from Moody's.The "midnight ceremony" he mentions is possibly a sarcastic take on the GST roll-out which happened at the historic Central Hall of Parliament, at the stroke of midnight on July 1.This is not a the first time Sinha has criticised the government's economic policies. In the past, he has gone so far as to blame finance minister Arun Jaitley for making a "mess" of the economy. He had called demonetisation "an unmitigated economic disaster" and the GST rollout "badly conceived and poorly implemented."Moody's on Friday bumped up India's local and foreign currency issuer ratings after 13 years, crediting the government's reforms, including the roll-out of the Goods and Services Tax (GST).Finance minister Jaitley took the opportunity to attack the opposition for its jibes on the note ban and the GST."Many who had doubts in their minds about India's (economic) reform process would need to now seriously introspect on their thinking," said Jaitley.India's chief economic advisor Arvind Subramanian had in May this year slammed rating agencies for not upgrading India "despite clear improvements in economic fundamentals" and accused them of being "inconsistent in their treatment of China and India."Playing on the name of Standard & Poor's, he had demanded to know why these rating analysts were even taken seriously, given their "Poor Standards."
