New Delhi, November 2: Sovereign Gold Bonds (SGBs) are government securities denominated in grams of gold. The government in November 2015, under Gold Monetisation Scheme, launched this. This form of investment is quite interesting as they are substitutes for holding physical gold. Investors have to pay the issue price in cash and the bonds will be redeemed in cash on maturity. The Bond is issued by Reserve Bank on behalf of Government of India.
