A Customer Wasn’t Happy With His Bank’s Savings and Interest Plan, So He Read the Fine Print, Opened More Accounts, and Ended Up Making a Lot of Money

There’s some sketchy business going down at banks these days, my friends!

And this Reddit user had quite a story to tell…

Get all the details below and see what you think.

Malicious compliance to a bank’s arrogant savings plan.

“Had to deal with a bank today and got pretty mad with their stupid procedures and bureaucracy (not the people that served me).

I literally started thinking about petty compliance to one of the topics and how well banks have protected themselves with legal documents and I remembered this golden story from my grandfather (may he rest in peace).

A couple clarifications:

a) will use the symbol $ when referring to money (for ease), but this is on a local currency

b) the story is a fairly long way back in time

c) back then salaries (monthly) would range between $170 up to $350 (stretching the upper end a bit)

The story:

So my grandfather was at a point in his life, with a wife and couple of young kids, settled in an apartment and was working in a factory and painting houses. He was working more than two 8 hour jobs, 6 days a week to provide as well as save money for the future and for the kids (and as it ended up the grandkids as well).

He was working hard and doing well.

So with about a double income, he was managing to put some money on the side each month.

He had gone to one of the local banks, and opened up a savings account with a healthy interest (different times…).

He put in some money (about $5k) and left it to grow.

A year later he went in the put in some more money and start a new “plan” for another year and the guy told him to go with one of their new plans where the interest was 2.5% (up from under 2% on the normal end-of-year paying plan he had) and this new plan was paying every day the interest, as well as he could add money each month, instead of once a year, before starting a new plan.

According to grandpa, even the fine print didn’t seem to have any negatives, so he went with it. About $7k at that point

3-4 months go by and he goes in to add some money to the account and asks for the account movements to be updated (back then, you had a booklet, that they put in an old style printer and it would add only what was not already printed… brand new tech back then).

He gets his print out and it is 4 months of daily $+0 interest added.

When you do the math 7000*0.025/365 you get about 48 cents per day that was not being paid.

What was going on here?

He asked why after 4 months of “daily payments” his deposit was still the same and the clerk smirked back that the amount was too small. The system was not calculating cents, just whole numbers. So with his amount being 7k, his daily payment was 48 cents rounded to 0…

He went to the director of the bank office and mentioned everything together with the fact that for over 100 days the bank had been keeping for itself 50 cents per day and how was that allowed, because it was robbing the customers and the director just responded with ‘in our bank, individual offices have the right to operate semi independently. This is why we are able to offer such a competitive interest rate, whilst our bank doesn’t offer it officially. We are allowed to set some rules for ourselves. If you don’t like feel free to change your position!’ (change your position meaning not be so poor).

According to my grandfather he was furious and just stood up and left. Went back home and read all the fine print of the contract again, only to find that information so vaguely written, that it could have been talking about weather temperature calculations…

He wasn’t gonna stand for this.

The malicious compliance:

He read it once more and two days later he went back to that office bank. He added some money to get the amount to $7,450 and left. No complaints, nothing.

He went back four days later to update his booklet with recent account movements and the system was paying $1 every day.

Since he confirmed this, he went to the other banks where he had accounts. He was a smart man and did not want to keep all his money in one place, but now he was on a revenge mission.

He took out all his money from the other banks and went back and opened up 2 more accounts with that exact same amount.

He also got the bank to pay those interest payments in a separate account, making sure that the amount was just right at $7,450. So he started getting $3 ($1 per account) every day. That was in a period when he was getting paid about $7 a day, for about 10 hours of work (or about 15, from his two jobs).

He wasn’t done yet!

This continued for so long, that with time passing and him saving more, he managed to get up to 8 such accounts, before they shut down that plan and changed it. According to him that run for over 11 years.

The way this worked was him pretty much netting a 5% interest rate, of the stupidity and arrogance of the bank, just because most people had under $7k in savings, so everyone subscribed on that plan was getting robbed, whatever they were owed.

He said that the interest rate fluctuated up and down a bit so he ended up getting the amounts up at 8k, just so he would be losing money when the rate was falling lower…

He said that according to his calculations he netted about $11k over what his money should have earned with that APY of 2.5%.”

That’s some smart malicious compliance!
