The Reserve Bank of India (RBI) will simultaneously buy (government bonds maturing in 2029) and sale (short-term bonds maturing in 2020) government securities worth ₹10,000 crore each under its open market operations.
It is a move aimed at managing the yields and to make long term borrowing cheaper.
As the central bank buys long term securities), the rise in demand for them leads to lower long-term yields.
Eventually, it is long term interest rates that matter for investment and growth in the economy.
This way the yield curve becomes “twisted” as short-term rates are pushed up and long-term rates are pushed down.
The central banks opt for this measure when despite lowering interest rates, the long-term interest rates remain high.
Open Market Operations (OMO) is one of the quantitative (to regulate or control the total volume of money) monetary policy tools which is employed by the central bank of a country to control the money supply in the economy.
OMOs are conducted by the RBI by way of sale or purchase of government securities (g-secs) to adjust money supply conditions.
About OT
This policy measure of buying long-term bonds and selling short-term ones is known as Operation Twist (OT).
The US has announced OT twice, the first time in 1961 during John F Kennedy and the second in 2011 during Obama.
Japan also announced its own version of OT called as Qualitative and Quantitative Easing program (QQE) in 2013.
