What is the process and price for encashment or early or premature redemption of SGBs?

Although the Sovereign Gold Bond (SGB) has a tenure of 8 years, it can be redeemed prematurely on coupon payment dates after the 5th year from the issue date.
RBI will open certain windows at the end of the 5th, 6th and 7th years when premature redemption of SGB will be allowed.
EARLY REDEMPTION PRICE: The early redemption price is determined on the basis of the average gold price of the previous week published by the India Bullion and Jewelers Association Limited (IBJA). RBI declares the early redemption price for every series of SGBs for different coupon payment dates.
