@Bhaskarsingh Yes. Not always buying in the secondary market leads to heavy premiums. For example, in T-Bills the Annualized ROI had been 12%+ many a times [Refer here.] (though such opportunities are hard to capture). We would be integrating both the types simultaneously.
For fresh issue, we need to wait for around a month as the NCL publishes a list of acceptable securities at around 20th of a given month. Any new ISIN is introduced in pledge acceptance only after then. However for re-issue just the wait is for a week as the ISIN is already under approved list of NCL.
