Where to park wedding fund

Stablemoney FD: no lock-in period, 8%+ interest

Depends on in how many years you plan to marry. If >= 4 years, put most of your money in an index fund or else invest in ultra short term funds. Former will give you ~12% annual returns while the latter around 8-9%. Invest 10% of your savings in gold, which can act as a hedge if gold prices shoot up and there is some jewellery shopping to be done close to the wedding time.

Liquid funds or a simple RD should work fine. I'm assuming your main aim here is preserving capital and not high growth. Most banks are offering ~7.1% interest on RDs > 1yr.

You can park in my account without interest or return guarantee 😉
