[CBC News] Mr. Kim (58), who retired last spring, had left his severance pay untouched for months, sitting idly in his primary bank account. Having a large sum of money suddenly appear felt unfamiliar, and not knowing where or how to invest it, he simply put it off.

When he met an old friend, the friend urged him to compare savings bank interest rates, saying it was a waste to just leave the money in a checking account. Kim said, "I didn't have high expectations since bank fixed deposit rates were so low, but when I actually looked into it, I was surprised by how big the difference was."

Concerns About Insolvency? Solved with 'Split Deposits' Within the Depositor Protection Limit

The first thing Kim worried about was safety. Recalling news about past savings bank insolvency crises, he was not entirely confident that moving his funds just because of higher interest rates was the right decision.

However, while browsing savings bank interest rate comparison websites and related information, he discovered that savings banks, just like commercial banks, are covered by the depositor protection system, and that the protection limit itself had recently been raised. Kim said, "Knowing that the amount I can deposit in one place has increased put my mind at ease."

Over the following days, he carefully examined the fixed deposit terms of several savings banks one by one. Even for the same one-year maturity product, there were significant interest rate differences between savings banks, and some products offering higher rates than the base rate upon meeting preferential conditions caught his eye. Rather than depositing his entire severance pay in one place, Kim chose to split his funds across several institutions offering top-tier rates, taking the protection limit into consideration.

Checking 'Preferential Conditions' is Key to Avoid Being Lured by Surface Rates Alone

When commercial bank deposit rates are unsatisfactory, utilizing savings bank interest rate comparisons often helps find products that offer better interest within the same safety net.

However, three things must be checked.

First, do not simply look at the surface rate; also examine the conditions for preferential interest rates. Additional rates are often applied based on factors such as registering for open banking accounts or being a first-time customer, so verifying whether you can meet these conditions in advance is necessary to actually earn interest close to the advertised maximum rate.

Second, since interest rates and preferential conditions change frequently at each savings bank, you must reconfirm the latest terms at the time of enrollment.

Third, if you plan to split a lump sum across multiple savings banks, you should also consider allocating amounts based on the depositor protection limit to ensure safety.

Kim ultimately divided his severance pay among several savings banks and secured better interest terms than before. He said, "I didn't pay much attention before because it was convenient to just leave it at my main bank, but after comparing this time, I really felt how much of a difference there is," adding, "If you have a lump sum, it's worth putting in the legwork at least once."

Kim's case clearly demonstrates that comparing savings bank interest rates is not something only special people do; it is a step worth checking at least once for anyone who wants to roll over a lump sum safely.
