IBJA Rate
The daily gold reference rate published by India Bullion and Jewellers Association, used by RBI for SGB pricing and by banks for loan valuation.
IBJA publishes a morning and evening gold rate every business day, based on a survey of 12 major bullion dealers. It is the closest thing India has to a neutral gold benchmark. Most retail jewelers quote a price that is IBJA + 0.5–2% margin. If your jeweler's per-gram rate exceeds IBJA + 2%, you are being overcharged.
