Many banks and financial institutions offer loans against gold, since it is a common form of secured lending. In India, for example, major providers include SBI, HDFC Bank, ICICI Bank, Axis Bank, Canara Bank, Punjab National Bank, and non-banking finance companies like Muthoot Finance and Manappuram Finance.
In the US, gold loans are less common through traditional banks but are offered by specialty lenders and pawn-style gold loan companies. Credit unions in some countries also provide this service.
Terms vary widely by lender, including interest rates, loan-to-value ratio, tenure, and processing fees, so it is worth comparing a few options before choosing. I am not a financial advisor, so please verify current rates and terms directly with any lender you are considering.
