The Nominal Illusion
Every return on this site's charts is a nominal return - plain price change with the currency itself unexamined. That is how the number is quoted, and it is also the number that misleads. If your portfolio earns 7% in a year while prices rise 3%, you have not gained 7%. You have gained about 4% of actual purchasing power, and the other 3% merely let you tread water.
Inflation does not announce itself in your brokerage app. It shows up in your groceries, your rent, and then - years later - in the realisation that your balance grew while its buying power thinned. The only way to measure investing honestly is real return: nominal return minus inflation.
The Simple Math of Shrinking Money
Take S$10,000. At 3% inflation, that same pile buys about S$7,400 worth of today's goods after ten years. To merely keep its value, every holding must beat inflation before it beats anything else.
The compounding post on this site shows why the distinction compounds too: at 7% nominal with 3% inflation, a 30-year run turns S$10,000 into roughly S$76,000 nominal but only about S$31,000 in today's purchasing power. The headline number is real money eventually spent; the purchasing-power number is what it actually buys. Plan with the second.
Where Inflation Feeds Quietly
Rank the safe-money holdings on this dashboard by how they handle a currency that shrinks:
- Cash in a bank account - a bank savings rate still sitting near 0% (or barely above it) while the SSB 10-year average is about 2.32% p.a. is cash losing ground by construction. Convenience is what it is for; it is not an inflation fighter.
- T-bills - the 6-month bill at roughly 1.6% p.a. (late 2026 reading) beats the savings account but still trails most inflation readings. Fine for twelve months of known cash; not a long-term store.
- Singapore Savings Bonds - the October 2026 issue's 10-year average of 2.32% p.a. is the best of the cash-adjacent bunch, and all of it is tax-exempt for resident individuals. It is also not a real-return champion - when inflation is hot, even the SSB's step-up schedule can lag it for stretches.
- CPF - this is the quiet winner of the safe tier. The Ordinary Account's 2.5% and the Special/Retirement Accounts' 4% (floor currently extended to 31 December 2026) are meaningful in Singapore's recent inflation climate, and CPF interest compounds tax-free. Your CPF balances are already doing inflation defence work.
Who Actually Defends You
The long-run answer to inflation is the part of the portfolio nobody finds exciting: broad equities. Over multi-decade horizons, global equities have historically delivered several percentage points a year above inflation - profits, not coupons, being the engine. That is not a promise for any single year; it is the reason an allocation to stocks is the only component that has historically grown real purchasing power rather than merely preserved it.
Two dashboard mentions with their honest roles:
- Gold (
GLD) - stores value but produces nothing. Its defence is against sudden currency stress and crisis, not a slow CPI grind. A hedge, not a growth engine. - Long bonds (
TLT) - pay a fixed coupon in dollars that inflation erodes in real terms. Duration makes them more sensitive, not less. Their job is stabilising a portfolio during stock crashes, and they can pay for that job in purchasing power during a long inflation.
The Singapore Twist
Two things make the safe tier work harder here than almost anywhere else: SSB and T-bill interest is generally exempt from personal income tax, and CPF's guaranteed rates sit above the cash market. The 2024-25 coupon bonanza - when T-bills opened 2026 at 3% before settling near 1.6% - was the exception, not the norm. In the low mid-1% band of cash yields, 2026 is about preservation, and the honest benchmark is simply beating the current SSB's 10-year average of 2.32%, tax-adjusted.
The Takeaway
Check every holding against real return, not headline return. Keep emergency cash where it belongs - liquid, modest - park the months-ahead money in SSBs, enjoy the CPF float, and put the money you can leave alone in the only thing that has historically out-run inflation: low-cost, broadly diversified equities. Inflation does not need to be forecast; it needs to be out-lasted.
