Deposit tools, rate comparisons, and savings strategies

Focus on three indicators: (1) execution rate (what you actually get), not just the posted rate; (2) whether the term and compounding method match your cash plan; (3) how stable the rate is—year-round or promotional. Also note the difference between APY (annual percentage yield) and APR (annual percentage rate)—the latter can underestimate compounding effects.

Three main differences: liquidity (demand is anytime, fixed has a term), yield (fixed is typically 3–5× higher), and risk (demand has no early withdrawal penalty, fixed reverts to demand rate if withdrawn early). If you might need the funds within 6 months, demand or notice deposits are better; if you can lock for 3+ years, fixed offers significantly higher returns.

Large CDs offer 20–40% higher rates than regular fixed deposits, but typically require a 200,000 minimum. If you have 200,000+ idle funds, can lock for 1–3 years, and prioritize stable returns over liquidity, large CDs are a good choice. The downside is relatively fixed terms, and early withdrawal may incur transfer fees.

Funds over 500,000 should be spread across at least two banks, as deposit insurance covers up to 500,000 per bank. A diversification strategy could be '500,000 at a primary bank + several 200,000–300,000 deposits at smaller banks'—this way you get the primary bank's higher rates while fully utilizing multiple banks' coverage limits. You can also mix fixed deposits, large CDs, and notice deposits to optimize liquidity.

It depends on two factors: (1) your cash needs timeline (if you might need it within 3 years, choose 3-year), and (2) your rate trend expectations. In the current rate environment, 3-year fixed deposits offer a good balance of liquidity and yield, but if the rate gap is significant and you can truly lock for 5 years, 5-year fixed deposits provide more absolute returns. You can use a CD ladder to mix both terms, balancing liquidity and yield.
