New Delhi, Jan 2 Terming the government's ways as strange, senior Congress leader P. Chidambaram on Tuesday asked "when did a tweet become a government order or notification" after the Economic Affairs Secretary tweeted that the 8 percent Savings Bonds Scheme is being replaced by a 7.75 percent scheme. "Last night, 8 percent taxable bonds were scrapped. I protested. This morning, Secretary tweeted that 7.75% bonds will be issued. No notification so far," tweeted Chidambaram. "When did a tweet become a government order or notification? Strange are the ways of this government," he added. Chidambaram also said: "Middle class, senior citizens, retirees waiting for official notification." Earlier in the day, Subhash Chandra Garg, secretary, Department of Economic Affairs, Ministry of Finance, tweeted: "8% Savings Bonds Scheme, also known as RBI Bonds Scheme, is not being closed. 8% Scheme is being replaced by 7.75% Savings Bonds Scheme." Chidambaram on Monday termed the Narendra Modi government's decision to scrap the '8 percent taxable bond' as a "severe blow" to the middle class and a "deplorable act". The government on Monday announced that the '8% GOI Savings (Taxable) Bonds, 2003' will cease for subscription with effect from the close of banking business on Tuesday, January 2. Introduced in 2003, the '8% bonds' are government of India bonds with a fixed rate of interest of 8 percent per annum paid half yearly. They are available in physical form only and are not listed or tradable on stock exchanges. The interest received from these bonds is taxable.
