Corporate Deposit Cap, as a percentage of the total bank deposits & Subsidiaries?

[GnoSiS]

Hello,

Just having a look at this feature & trying yo understand the design and reason behind it.

If it's meant to prevent a large corporation from from backing the entire deposits of a bank, then does the simulation check for ownership of shell subsidiary companies? because if not,
with a 20% setting I can create 5 of them and bypass the rule for instance.

How do you plan to deal with large/excessive deposit amounts? Will there be deposit caps or something else so that no individual or corporation deposits will exceed say 1%-10% of Banks Total Deposits?

It would be unrealistic for a single character or company to say deposit $2.5-$50 Billion into a bank that only has $5 Billion in deposits. The amount of loans that banks compete for should also be limited by the economy for regular loans and corporations borrowing needs.

In your opinion, should the deposit caps be a percentage of the bank's total deposits? If so, what percentage is reasonable?

But the player can still use multiple subsidiaries to make deposits into a single bank, with an aggregated amount accounting for half or more of the bank's total deposits.

When the player decides to withdraw all the deposits at the same time, the bank will suffer liquidity problems. Do you think of any way that the game can block the player from performing such a trick to attempt to kill a bank?

Yes, Deposit Caps should be a percentage of banks total deposits.

As for the Percentages I initially said 1%-10% but after further consideration it should probably be at the lower end of the range. In this FDIC Regulation Manual page 12 deposit concentration, it says that “a large depositor is a customer or entity that owns or controls 2% or more of the bank’s total deposits.”

So, a reasonable cap for both individuals and corporations would be 2.5%-3.0% of Deposits.

As for the subsidiary issue I can see a couple ways to deal with it:

• Simple Global Corporate Deposit Cap:
o All companies that you have financial control over (~51% ownership) can only deposit money up to the global cap 2.5%-3% for that bank. This would not be preferred but, it is an option.

• Scaling/Tiered Deposit Cap:
o Once companies that you have financial control over (~51% ownership) deposits meet the initial cap of 2.5%-3.0% of deposits any additional subsidiaries can only make up 0.5%-1% of a bank’s deposits. There would also be a Global Cap for all controlled companies of ~10%-20% of Banks Deposits.
- Parent: 1.5% of Banks Deposits
- Subsidiary 1: 1.5% of Banks Deposits
- Subsidiary 2+: 0.5%-1.0% of Banks Deposits
- Combined Companies: 10%-20% Deposits
o Or Simply Parent Company Deposit Cap 2.5%-3.0% of Bank Deposits. Subsidiary Deposit Cap 0.5%-1% of Banks Deposits. Global Cap for controlled companies of ~10%-20% of Banks Deposits.
o Either of these would make it so that you would require a significant number of subsidiaries to gain substantial portion of an individual bank’s deposits with an overall limit.
o A bank should have liquid investment reserves worth 10%-20% of deposits in bonds and short term notes that they could sell if depositors withdraw their money.

•Does anyone else have any ideas for a solution to this problem?

Another thing to think about is possibly having an alternative place for companies and individuals to park their cash for protection of principle, liquidity and to earn some interest. In the real world it is normal for large organizations or wealth individuals that have money that exceed deposit limits to park the majority of their cash in the money market otherwise known as short term high quality short notes, bills, and commercial paper that mature in less than a year issued by governments and companies. For example, one of the organizations that I have worked for keeps $100-$300 million in cash/bank accounts and the rest of the $3+ Billion Treasury in high quality money market instruments.

Potential Money Market Systems:

•Money Market Facilitated by Bank:
o Separate “Deposit” account that is not linked to other bank deposits where Bank “Purchases” High Quality Government Bills, Commercial Paper, etc. for you and charges you a percentage of the interest for the service.
o Interest: 50%-75% of Bank Savings Account rate or 2%-4% Yield/Interest
o Management/Service Fee: 0.25%-0.35% Assets

• Separate Money Market like the Stock and Bond Markets:
o Investments:
- Maturity: 3 or 6 Months
- Yield/Interest is Based on discount to Par Value so you buy investment for say $98 and they pay you $100 when it matures.
o Investments Options:
- National Government Bills: National Government Debt Market: ~40%-100% of Nations GDP (~20%-30% Short Term Bills)
- City Notes (Tax Revenue Anticipation Notes): Market: 5%-10% of City Annual Budget, Simulate the mismatches in tax revenue and expenses?
- Commercial Paper: Have “Local” firms issue them. Possibly allow companies to issue commercial paper to fund short term borrowing needs like paying bond interest payments (6 months), periods with cash flow issues, etc.

Yep, the dev team implemented Corporate Deposit Cap based on standardplayer's suggestion.
