Deposit Distribution Strategy Topic
Principal safety is not an abstract concept but requires specific allocation by amount tier. Centering on keeping principal and interest below the coverage limit per bank can significantly reduce concentration risk for large savers.
How to safely allocate 500k+ deposits? At this stage, what's most needed is usually not calculating a bit more interest, but first sorting out single-bank risk exposure, future cash flow arrangements, and whether rate differences are worth pursuing.
Deposit diversification doesn't mean mechanical equal splitting. A more suitable approach for ordinary savers is often to split by purpose first, then by bank, and finally by term. This way, you can make good use of deposit insurance boundaries without sacrificing liquidity due to all funds moving in and out together.
If principal and interest are clearly below the coverage limit, prioritize convenience and execution rates without excessive splitting.
This is the most typical range requiring splitting. Generally recommend 2-4 banks with term mismatching to maintain liquidity.
Not only split by bank, but also by term and product type, avoiding putting all liquidity and safety in one place.
Reference Allocation by Amount Tier
| Total Funds | Recommended Split | Strategy Focus |
|---|---|---|
| 300k | 1 bank sufficient | Prioritize high execution rates and convenient withdrawals |
| 800k | Recommend 2 banks | Keep each around 400k, reserve space for principal and interest |
| 1.5M | Recommend 3-4 banks | Balance 1-year and 3-year terms, retain emergency cash |
| 3M | Recommend portfolio allocation | Split by bank, term, and product type to control concentration exposure |
Three Core Principles of Deposit Diversification
- 1. First estimate risk exposure by "single bank principal and interest total", not just whether principal exceeds 500k.
- 2. Then decide how many banks to split into, avoiding maxing out safety boundaries at once to chase high rates.
- 3. Finally split by liquidity needs and terms, don't lock all money into the same long-term product.
Most Common Mistakes
- Only looking at rates, not checking if principal and interest total will breach coverage limits.
- Putting all money into one bank's high-rate promotional product, ignoring diversification.
- Completely sacrificing liquidity to chase high rates, resulting in forced early withdrawal when cash is needed.
- Splitting banks but not terms, resulting in everything maturing or locking at the same time.
