I don't the data exactly to show if the Gold was placed as a security but surely India got lot many secured loans from multiple institutions. here is the info on just world bank (Keep in mind these are secured loans so it could be gold)

FYI...The Indian govt had already applied for funding to support the most recent scheme of Rs160000/- Crore (Food Security Bill).
The populists scheme announced recently without finding the source of income for those schemes, was the reason Rupee got depreciated by 40%.
The current deficit of India is approx. 4.3%. Indian economy is on the verge of one more downgrade and getting closer to junk (I apologize for using the economic term used by creditors)
