Japan’s Lost Decades, China’s Economy and the Eurozone

Understanding the world economy while skipping China would be like studying the solar system while skipping Jupiter. Since Deng Xiaoping’s 1978 reforms opened the economy, China grew at nearly 10% a year for three decades, becoming the world’s factory (still ~30% of global manufacturing), largest exporter, largest trading partner of over 120 countries, and second-largest economy — largest by PPP (chapter 1.14: Purchasing Power Parity — Why GDP Rankings Deceive).

The model differs from Western capitalism in structural ways. State-owned enterprises dominate banking, energy, and telecom. The big state banks lend where policy directs, not merely where returns beckon. The yuan is managed, not freely floating, and China maintains capital controls — citizens and firms cannot freely move large sums abroad, which is also the deepest reason the yuan cannot yet rival the dollar as a reserve currency (chapter 2.6: BRICS and the Challenge to Dollar Dominance): reserve holders demand the exit rights that Beijing, valuing control, will not grant. Five-year plans steer capital toward chosen industries — the current chosen ones being semiconductors, EVs, batteries, and AI, in explicit response to US export controls (chapter 7.4: The Semiconductor Geopolitical Crisis). The Belt and Road Initiative extended this model abroad: over a trillion dollars of infrastructure lending across Asia and Africa, buying influence and creating debtor relationships that reappear in chapter 9.4: When Countries Go Broke — Sovereign Default and the IMF.

The strains are now equally structural. The property sector — once ~25–30% of GDP with land sales funding local governments — entered a grinding multi-year bust after Beijing restricted developer leverage in 2020; giants like Evergrande (liquidation ordered 2024) and Country Garden defaulted, and with roughly 70% of household wealth stored in apartments, falling prices crushed consumer confidence. Add heavy local-government debt, youth unemployment high enough that the statistics were temporarily suspended, deflationary pressure while the West fought inflation, tariff walls rising against its exports, and a population that began shrinking in 2022 (chapter 1.15: Demographics — The Slowest, Strongest Force in Economics) — and China’s central question becomes whether it escapes the middle-income trap and grows rich before it grows old. For India, China is simultaneously largest goods-trade partner, chief strategic rival, the manufacturing benchmark to chase, and — through “China + 1” (chapter 1.16: Tariffs, Trade Wars, and the Age of Friend-Shoring) — the source of its biggest industrial opportunity in a generation.

The 1980s bubble was spectacular — cheap credit flooded into stocks and land after the 1985 Plaza Accord — an agreement among the US, Japan, West Germany, France, and the UK, signed at New York’s Plaza Hotel, to deliberately weaken the overvalued dollar. The yen nearly doubled in value within three years, and the Bank of Japan slashed interest rates to cushion its suddenly less competitive exporters — and that cheap money fed the boom until the Nikkei index closed at 38,915.87 on December 29, 1989 (its intraday high that day was 38,957.44). Then the central bank raised rates, and both markets collapsed: the Nikkei fell about 82%, to an intraday low of 6,994.90 in October 2008, urban land followed, and banks were left holding mountains of loans secured against evaporated collateral. Crucially, Japan spent the 1990s concealing rather than confronting the damage — banks kept insolvent “zombie companies” alive with fresh loans to avoid admitting losses, spreading the pain across decades instead of absorbing it quickly. (The US response in 2008 — rapid forced recapitalization — was consciously designed as the anti-Japan playbook.)

What followed was the deflationary trap that chapter 1.8: Inflation and Deflation — Why Prices Rise and Fall warned about, in full scale: consumers delayed purchases because prices would be lower next year, firms couldn’t raise prices so couldn’t raise wages, cautious spending validated the caution. The Bank of Japan pioneered every emergency tool the world later borrowed — zero interest rates (1999), quantitative easing (2001), even negative rates (2016) and direct stock-market purchases — and still couldn’t restart inflation for a generation. Government debt swelled to more than 200% of GDP (the IMF‘s gross measure: 228.8% in 2020, 206.5% in 2025), the highest of any large economy, sustainable only because it’s owed overwhelmingly to Japan’s own citizens and central bank at near-zero rates.

The epilogue arrived only recently: the global inflation shock of 2021–23 finally jolted Japanese prices and wages upward; on February 22, 2024, the Nikkei closed at 39,098.68, finally above its 1989 closing high of 38,915.87, a 34-year round trip. In March 2024 the BOJ ended negative rates, raising them for the first time in 17 years, and on September 18, 2026, it voted 7-2 to lift its policy rate to 1.25%. The index closed at 68,309.46 on October 2, 2026, 68,309.46 ÷ 38,915.87 ≈ 1.76 times its 1989 peak: it has now run well past the old summit. The lessons are permanent: bubbles are obvious only in hindsight; delay in cleaning up banking losses multiplies their cost; deflation is harder to escape than inflation; and demographics (Japan is Earth’s oldest large society) can quietly cap everything policy attempts. Every central banker alive studies Japan the way pilots study crash reports.

The euro (launched 1999) is history’s boldest monetary experiment: a currency union without a fiscal union. Members surrender their exchange rate and their printing press to the European Central Bank, but keep national budgets. The design removed two classic shock absorbers at once — a struggling member can no longer devalue its currency to regain competitiveness, nor rely on a central bank of its own as guaranteed lender of last resort. In the boom years this flaw hid: markets lent to Greece at nearly German rates, as if the union had equalized risk.

The Greek crisis exposed everything. In 2009 Greece admitted its deficits had been drastically understated; bond yields exploded, from about 5.5% in December 2009 to a monthly average near 29% in February 2012 (ECB long-term rate series) (the bond-market discipline of chapter 2.9: Bonds and the Yield Curve — The Market That Rules Them All, at maximum voltage); and because Greece couldn’t print euros, default loomed. Three bailout programs (2010, 2012 and 2015, together well over €200 billion) from the EU, ECB, and IMF followed — conditioned on brutal austerity: spending cuts and tax rises that deepened the slump. Greek GDP contracted by roughly a quarter, unemployment reached about a quarter of the labor force, and a generation emigrated. The crisis spread to Ireland, Portugal, Spain, and Cyprus, and paused only when ECB President Mario Draghi uttered the most powerful three words in central-banking history — “whatever it takes” (July 2012) — committing the ECB to backstop member bonds. Yields collapsed on the sentence alone: a pure demonstration that credible central-bank words can outgun any budget.

The permanent lesson, now called the theory of optimal currency areas: currency unions need fiscal transfers, mobile labor, or shared debt to survive uneven shocks — the US survives regional recessions because Washington quietly redistributes; the eurozone had no such machinery and has since built only partial versions (a bailout fund, banking union, and the first common EU borrowing during COVID). This chapter is also the essential caution for every “BRICS common currency” headline (chapter 2.6: BRICS and the Challenge to Dollar Dominance): if culturally intertwined European neighbors found sharing a currency this hard, the bar for looser groupings is far higher. Giving up one’s own money is not only a European choice: Section 9.7: The Rest of the World: Capital-Flow Stories from Emerging Markets follows the countries that adopted the dollar.
