04 · Inflation and Purchasing Power
Inflation is the easiest thing for ordinary people to ignore — and it happens every day: your money isn't shrinking in number, but what it buys is. This chapter explains how inflation figures are produced, whether inflation is friend or foe for each asset class, and which parts of "beating inflation" are real and which are marketing.
1. What Is Inflation: Where CPI Comes From
1.1 How CPI is constructed
CPI (Consumer Price Index) reflects price changes of a fixed basket of goods and services. The statistics bureau samples monthly, weighting hundreds of items across 8 major categories:
| Category | Approximate weight (China's CPI basis, historical data) | Notes |
|---|---|---|
| Food, tobacco & alcohol | ~30% | Largest weight; pork prices often "drive" the headline |
| Housing (mainly rent) | ~20%+ | Note: home purchase prices are excluded; only rent and utilities count |
| Transport & communication | ~10% | Sensitive to oil prices |
| Education, culture & recreation | ~10%+ | Includes tuition and training |
| Healthcare | ~8% | |
| Clothing, household goods, others | Remainder |
Key understandings:
- Weights reflect the "average person's" spending structure, not yours. Different spending structure, different felt inflation.
- CPI measures "price changes," not asset prices: housing, equities, education, and healthcare can rise far faster than the CPI print.
- Heavy categories can be dragged down by single items: food carries a big weight, so a pork-price collapse pulls CPI down — but your rent and tuition didn't fall.
1.2 Why your felt inflation exceeds CPI
| Items you feel keenly | How CPI treats them |
|---|---|
| Rising rents | Counted under housing, but with limited weight and statistical lag |
| School-district homes / house prices | Not counted (only rent); lived experience diverges from statistics |
| Education (tutoring, extracurriculars) | Counted but thinly sampled; private-sector price hikes feel sharper |
| Healthcare (out-of-pocket, medicines) | Counted, but insurance-reimbursed parts don't show |
| Services (haircuts, domestic help, repairs) | Low weight, low sampling frequency |
Conclusion: CPI is the "statistical temperature of the average person"; your felt inflation is the "real-time temperature of your own consumption basket" — a persistent gap between them is normal. When planning family finances, compute with your own household's felt inflation, not the published figure. Families with homes and children typically experience significantly higher inflation than official readings.
1.3 A few historical episodes of Chinese inflation
(All historical data, not indicative of future results)
| Period | Conditions | Effect on households |
|---|---|---|
| Mid-late 1990s | High inflation (some years CPI 20%+) | Real deposit returns negative; tangible assets held up better |
| 2007–2008 | Food inflation elevated (CPI 5%+) | Cost of eating surged; savings purchasing power shrank fast |
| 2011–2012 | CPI 5%+ | Deposit rates ~3% then; real rates negative |
| 2016–present | CPI mostly 0–3% | Headline inflation mild, but housing, education, services rose markedly |
Takeaways: ① years of high nominal inflation in China are not rare historically (historical data); ② more important is structural rises — even when CPI is mild, education and healthcare costs can far outrun the average; ③ felt inflation depends on "what you buy," so allocation should match "your consumption structure."
1.4 Inflation as a "wealth tax": who pays, who collects
- Inflation is fundamentally the dilution of money's purchasing power: every yuan depreciating is an invisible tax on holders of money.
- Collectors: the issuing government (diluting debt via inflation), enterprises with pricing power, and holders of real or equity assets.
- Payers: those holding cash and fixed nominal incomes — large depositors and people living on fixed pensions are inflation's biggest "taxpayers."
2. Inflation's Effect on Each Asset Class
| Asset | Under inflation | Notes |
|---|---|---|
| Cash (demand / deposits) | Certain erosion | Nominal loss zero; real purchasing power falls yearly |
| Deposits / money market funds | Trail high inflation | Rates usually sit below high-inflation periods; real returns negative |
| Bonds (fixed coupons) | Pressured | Inflation up → rates up → existing bond prices down; inflation-linked bonds excepted |
| Stocks (broad-based indexes) | Resist over the long run | Firms hold pricing power and pass costs on; but high-inflation periods compress valuations — a bumpy ride |
| Real estate | Historically resilient | Tangible asset; rents and replacement costs track inflation; heavily influenced by policy and liquidity |
| Gold | Shines in high inflation | Yields nothing, mediocre long-term returns; its role is hedging "monetary-credit crises" (hedge) |
| Crypto assets | No stable link to inflation | Highly volatile, short history; not an anti-inflation tool (historical data, not indicative of future results) |
Why stocks resist inflation long-term: inflation ultimately shows up as "growth in nominal revenues," and broad indexes represent "collections of firms that can raise prices and profits" — across major markets over recent decades, broad-index nominal returns have generally outpaced contemporaneous inflation (historical data, not indicative of future results). That doesn't mean "buying stocks = beating inflation": during sustained high inflation (e.g., the US in the 1970s), equity markets can stagnate for years.
2.1 Ranking assets' inflation resistance
| Tier | Assets | Logic |
|---|---|---|
| Strong | Firms that can raise prices (broad indexes, consumer brands, utilities) | Pricing power directly passes through inflation |
| Medium | Property (rent), gold | Tangibility hedges currency debasement, but bumpy and without growing cash flow |
| Weak | Bonds, deposits, money market funds | Fixed nominal income; real returns negative in high inflation |
| None | Pure cash | Certain erosion |
Caveat to this ranking: any asset's "inflation resistance" is a long-term statistical tendency, not a short-term guarantee — entry valuation, rate environment, and policy all rewrite short-run outcomes.
3. The "Negative-Rate" Era: Yu'e Bao's Yield Trajectory
Money-market yields are the thermometer of "market rates." Taking Yu'e Bao's seven-day annualized yield as an example (historical data, not indicative of future results):
| Period | 7-day annualized (approx.) | Context |
|---|---|---|
| 2013–2014 | 4%–6%+ | Launch era: high rates plus a rush of inflows |
| 2015–2018 | 3.5%–4.5% | Easy liquidity; yield center drifting down |
| 2019–2020 | 2%–3% | Accommodative monetary policy |
| 2021–2023 | 1.5%–2.5% | Rate center steadily declining |
| 2023–2025 | 1%–2% (some periods below 1.5%) | Low-rate era |
What this curve means:
- The era of "deposit and live off interest" is over: deposit and money-market returns have gone from "keeping pace with half of inflation" to "barely matching or trailing it."
- Falling nominal rates are a global trend: Japan and Europe have lived with negative or near-zero rates (historical data); China's low-rate drift is a natural part of rate liberalization — not necessarily the path ahead.
- For households: interest earned while idle is being nibbled away by inflation — keeping most money in demand/time deposits today amounts to "voluntarily losing purchasing power each year."
3.1 Deposit rates vs inflation: the real ledger
(Historical data, not indicative of future results)
| Period | 1-year benchmark deposit rate (approx.) | CPI (approx.) | Real rate |
|---|---|---|---|
| 2010–2013 | 3%–3.5% | 2.6%–5.4% | Mostly negative |
| 2015–2019 | 1.5%–2% | 0.8%–2.5% | Around zero or slightly negative |
| 2020–2024 | 1.5% (cut repeatedly) | 0.2%–2.5% | Around zero or slightly negative |
Numeric example (illustrative figures): a CNY 100,000 one-year deposit placed in 2011 earned about CNY 3,500 nominal interest; with CPI around 5.4% that year, real purchasing power fell by roughly CNY 1,900 — in some years, "saving" was a certain loss. Today nominal inflation is lower, but deposit rates have also fallen to 1%+, so real rates still hug zero.
Implication: in a low-rate era, beating inflation requires "accepting some volatility" — moving money moderately from "certain but meager" deposits into stock-bond portfolios that fluctuate but yield over time (see 01 - Asset Allocation Basics). Doing nothing is today's greatest risk.
4. Purchasing Power in Numbers
4.1 CNY 1,000,000 in cash, 20 years later
At 3% annual inflation: real purchasing power = 1M ÷ (1.03)²⁰ ≈ 554k — after 20 years, the same million buys what CNY 550k buys today.
| Annual inflation | Purchasing power in 10 years | In 20 years | In 30 years |
|---|---|---|---|
| 2% | 820k | 670k | 550k |
| 3% | 740k | 550k | 410k |
| 4% | 680k | 460k | 310k |
Note: at a 1.5%–2% deposit rate, real return ≈ rate − inflation = −1% to −1.5%/year — holding pure cash/deposits means compounding your way downward in certain negative real terms (compounding in reverse).
4.2 An intuitive felt example
- A bowl of noodles costs CNY 15 today; at 3% inflation, roughly CNY 36 in 30 years.
- If you rely only on deposits, your retirement savings' purchasing power will be less than half of today's.
- Conversely: on a CNY 10,000 salary, maintaining the same living standard in 10 years takes about CNY 13,400 at 3% inflation.
4.3 Do wages rise with inflation?
- Nominal wage = real wage × inflation: during inflation, nominal wages rise — whether that's "rising in name only" or genuine improvement depends on real wages.
- Real wage growth = wage growth − inflation. Only the portion where wage growth beats inflation is true income growth.
- Career implication: occupations whose pay tracks inflation (scarce skills, strong bargaining power) naturally resist inflation; easily replaceable jobs see nominal pay slowly eaten away. So the first anti-inflation tool is always raising your human capital.
5. Anti-Inflation Toolkit
| Tool | Anti-inflation logic | Best for | Caveats |
|---|---|---|---|
| Broad-based indexes (CSI 300 / CSI 500 / S&P 500 etc.) | Corporate earnings and pricing power grow with inflation | Long-term money, 10 years+ | High volatility; you must be able to hold |
| Dividend stocks / dividend indexes | High-payout firms tend to be stable, price-raising businesses | Conservative long-term allocation | Mind sector concentration (energy/banks/utilities) |
| Gold (incl. gold ETFs) | Hedge against fiat-credit risk | 5%–15% satellite sleeve | No yield, non-trivial volatility |
| Property (core cities) | Tangible asset + rents tracking inflation | Owner occupancy first; investing requires rent-price ratio and liquidity analysis | Policy risk, poor liquidity, high transaction costs |
| Price-raising firms (brands, utilities etc.) | Pricing power = anti-inflation moat | Investors able to research individual stocks | Single-company risk; mind valuation |
| Inflation-linked bonds/deposits (e.g., some structured products) | Returns partly tied to CPI | Conservative investors seeking certainty | Scarce products, complex terms — read before buying |
🛑 Doing nothing is today's greatest risk
Doing nothing is today's greatest risk. In a low-rate era, beating inflation requires accepting some volatility — moving money from certain-but-meager deposits into stock-bond portfolios that fluctuate but compound.
Two practical reminders:
- Your first anti-inflation tool is human capital: raises, skills, competitiveness — for young people the strongest weapon against inflation is income growth, not portfolio yield.
- Don't buy assets you don't understand in the name of fighting inflation: much "anti-inflation" marketing (crypto groups, property tours) is really anxiety harvesting. First make sure you don't lose; only then talk about winning.
5.1 Portfolio view: what counts as an "anti-inflation allocation"
| Inflation scenario | Allocation leaning (reference) | Avoid |
|---|---|---|
| Mild inflation (2%–3%) | Normal stock-bond mix, stocks-led | All cash / deposits |
| High inflation (5%+) | More gold/commodities, less pure bonds | Heavy long bonds, large time deposits |
| Stagflation | Gold + cash; reduce equities | High leverage, long-duration bonds |
| Deflation | Cash + government bonds | Property, commodities |
Principle: allocation prepares for "possibilities," not predictions — precisely because the inflation path can't be predicted, portfolios keep stocks, bonds, gold, and cash side by side (see the Permanent Portfolio logic in 01 - Asset Allocation Basics).
6. Stagflation and Deflation Essentials
| State | Definition | Effect on assets | Response |
|---|---|---|---|
| Inflation | Prices rising moderately | Stocks benefit long-term; deposits suffer | Hold normal stock-bond mix |
| Stagflation (stagnation + high inflation) | The most painful macro state | Equity valuations crushed, bonds eroded, gold and commodities fare better (historical data) | Hedge with gold/commodities; cut stock and bond exposure |
| Deflation (persistent falling prices) | Cash purchasing power rising | Cash and government bonds win; stocks and tangible assets pressured; debt burdens worsen | Hold cash/government bonds; repay debts |
One-line memory:
- Inflation era: money burns; assets (especially stocks) keep better.
- Deflation era: cash is king; debt is a burden — repay first.
- Stagflation era: no perfect answer — diversify and lower expectations.
6.1 Three common misconceptions
| Misconception | Truth |
|---|---|
| "CPI is just 1%, no inflation pressure" | Your consumption basket (education/healthcare/rent) may inflate far beyond CPI |
| "Inflation's coming — buy property/gold, safest bet" | In high inflation, property gets policy-suppressed and gold swings wildly; both are clear only in hindsight |
| "Deflation is good, things get cheaper" | Deflation brings unemployment and falling incomes; shrinking aggregate demand hurts most people |
7. Quick Reference
| Question | Answer |
|---|---|
| Why does CPI diverge from lived experience? | Weights reflect the "average person"; excludes house prices; statistically lagged |
| What happens to cash? | No nominal loss; certain erosion of real purchasing power |
| Who resists inflation long-term? | Broad-based indexes (corporate pricing power); core-city property (historical data) |
| Gold's role? | Hedges monetary-credit crises; yields nothing, mediocre returns |
| 1M at 3% inflation for 20 years? | Only ~550k of purchasing power remains |
| What to do in a low-rate era? | Accept low yields; use "long-term money" to take volatility in exchange for return |
| Stagflation/deflation playbook? | Stagflation: gold; deflation: cash and repay debts |
⚠️ Risk Warning
All inflation, rate, and return data here are historical data, not indicative of future results, provided to illustrate mechanisms and orders of magnitude. China's CPI weights and methodology follow the National Bureau of Statistics' publications. Every anti-inflation vehicle (stocks, gold, property, etc.) risks losing principal; past performance does not indicate future results — decide independently according to your own risk tolerance.
