What You'll Find Here
I've been watching the yuan for over a decade. Honestly, the "overvalued or undervalued" debate often feels like two people arguing over whether a glass is half empty or half full—while the glass itself is changing shape. Let me walk you through what I've learned on the ground, and why the answer is more nuanced than a simple yes or no.
Why the Yuan's Valuation Matters
Whether the yuan is overvalued or undervalued affects your money directly: if you trade with China, invest in Chinese assets, or travel there. An undervalued yuan makes Chinese exports cheaper but your overseas purchases more expensive; an overvalued yuan does the opposite. But there's a deeper layer: the valuation also reflects the health of China's economy and the effectiveness of its policy toolkit.
The Case for Undervaluation
The classic argument: China runs massive trade surpluses, holds $3 trillion in reserves, and its purchasing power parity (PPP) suggests the yuan is 20–40% too cheap. Let's break that down.
Purchasing Power Parity (PPP)
The IMF's latest World Economic Outlook (the data is publicly available) shows that China's GDP per capita in PPP terms is about $23,000, while the nominal per capita income is roughly $12,000. That gap implies the yuan is significantly undervalued by PPP. But here's the catch: PPP comparisons work best for nontraded goods. In reality, a haircut in Beijing costs about the same as in New York after adjusting for quality—so the gap is narrower than PPP suggests.
Trade Surplus and Current Account
China consistently runs a current account surplus—around 2% of GDP in recent years. Under a free-floating regime, that surplus would push the currency higher. Yet the yuan hasn't appreciated much against a trade-weighted basket (the CFETS index). That's a sign of deliberate under-valuation. But is it still true today? Let's look at the trends.
| Measure | Typical Signal | Yuan Status (Recent) |
|---|---|---|
| PPP vs nominal GDP gap | Undervalued | ~30% gap, but narrowing |
| Current account surplus | Undervalued | ~2% of GDP, slowly declining |
| Real effective exchange rate (REER) | Relative to partners | Near long-run average |
| Capital flows | Overvalued if outflows surge | Net outflows, but controlled |
Notice the REER: after years of gradual appreciation, the yuan's real effective exchange rate has stabilized. That makes me think the undervaluation argument is weaker than it was five years ago.
The Case for Overvaluation
Flip the coin: capital flight, property market turmoil, and slowing productivity growth suggest the yuan could be overvalued. Let's dig in.
Capital Outflows and Pressure
Since 2014, China has seen periods of heavy capital outflows—businesses and individuals moving money abroad. To defend the yuan, the People's Bank of China (PBOC) burned through reserves (though they've since stabilized). If the yuan were truly undervalued, wouldn't capital be flooding in? Instead, the consistent net outflows hint that many insiders think the currency is worth less than the official rate.
Property Sector and Debt
I've visited several Chinese cities over the years. The empty skyscrapers in some tier-2 cities are haunting. The property crash since 2021 wiped out trillions in household wealth. When domestic assets lose value, the currency often follows. Some economists argue that the yuan needs to depreciate to offset the drag from real estate.
Productivity Growth Slowdown
China's total factor productivity growth has slowed from 3–4% per year to maybe 1–2%. A country that grows slower should see its currency weaken in real terms over time—unless artificial support props it up. That suggests the yuan may be overvalued relative to its underlying fundamentals.
How I Track the Yuan's Real Value
Instead of relying on one model, I look at a basket of market signals. Here's my routine:
- CNH vs CNY spread: The offshore (CNH) rate often trades at a discount of 100–300 basis points when pressure is high. If the gap widens, the market thinks the onshore rate is too high.
- One-year forward points: A deep discount in forwards signals expectations of depreciation.
- Cross-border flow data: Monthly data from SAFE shows whether capital is flowing in or out. I check that every quarter.
- Local prices: Anecdotal but powerful. I ask friends in Shanghai: "How much does a Starbucks latte cost?" If it's 35 yuan, that's about $5—expensive by local income standards. That kind of sticker shock suggests the yuan might be strong in purchasing power for everyday goods.
Policy Factors: Managed Float & Capital Controls
You can't talk about yuan valuation without understanding the PBOC's playbook. The central bank sets a daily midpoint, allows the spot to trade within a ±2% band, and intervenes to smooth volatility. Capital controls—like quotas on outward investment and strict approval for large transfers—create a wedge between onshore and offshore rates.
What does that mean for valuation? The official rate can stay overvalued for a while if controls hold. But leaks always exist. I've seen companies use fake trade invoicing to move money out—that's a sign of pent-up depreciation pressure. The PBOC knows this, so they gradually allow the yuan to weaken over time rather than in one crash.
