Important: Fixed Deposit Safety & Insurance Coverage
₹5 Lakh Insurance Limit
The Deposit Insurance and Credit Guarantee Corporation (DICGC) provides insurance coverage of up to ₹5 lakhs per depositor per bank. This means if you deposit more than ₹5 lakhs in a single bank, only ₹5 lakhs is guaranteed by the government.
⚠️ Recommendation:
Never deposit more than ₹5 lakhs in a single bank. If you have larger amounts, distribute them across multiple banks to ensure full insurance coverage.
Smart Distribution Strategy
For ₹10 lakhs: Split between Sundaram Finance (₹5L) + IOB (₹5L)
For ₹15 lakhs: Add a third bank to the mix
Best of Both: Combine Sundaram Finance (convenience) with IOB (security)
💡 Pro Tip:
You can also open FDs in different family members' names in the same bank to get additional ₹5 lakh coverage for each account holder.
