Princes of the Yen: Japan’s Central Bankers and the Transformation of the Economy** **2025 Restored & Expanded Edition** **Comprehensive Chapter Summaries (Chapters 1–10
Chapter 1: The Puzzle of the Japanese Miracle
The book opens by dismantling the standard narrative of Japan’s post-war economic miracle (1945–1990). Mainstream economics credits high savings rates, export discipline, MITI industrial policy, and cultural factors like lifetime employment. Werner demonstrates these are symptoms, not causes. The true driver was the **Bank of Japan’s (BoJ) covert credit creation** via *window guidance*—quarterly directives to commercial banks dictating *how much* and *to whom* they must lend. Using declassified BoJ data, Werner shows that **credit growth preceded GDP growth by 6–9 months** in every major boom (1955–1973, 1986–1990). He contrasts this with textbook monetarism, which claims money supply follows demand. In Japan, the BoJ *created* demand by pre-allocating credit to steel (1950s), shipbuilding (1960s), and semiconductors (1970s). The chapter ends with a leaked 1955 BoJ memo stating: *“Interest rates are for public consumption; real policy is lending volume.”* This sets the stage for the entire thesis: **central banks, not markets, planned Japan’s economy**.
**Chapter 2: The Ministry of Finance and the Bank of Japan** This chapter traces the institutional rivalry between the **Ministry of Finance (MoF)** and the **Bank of Japan** from the Meiji era (1868) to 1998. The MoF controlled tax revenue, budgets, and bank supervision; the BoJ controlled *credit volume*—the lifeblood of growth. Werner uncovers a **1920s power struggle** when the BoJ first proposed *window guidance* to bypass MoF fiscal restraint during the Showa Depression. Post-WWII, under SCAP (U.S. occupation), the BoJ was subordinated to the MoF, but began a **50-year campaign** to regain autonomy. Key turning points: – **1952**: BoJ secretly restarts window guidance despite legal ban. – **1973**: Oil shock—BoJ uses credit expansion to shield exporters, defying MoF austerity. – **1985**: Plaza Accord—BoJ lowers rates *without MoF approval*, triggering the bubble. Werner reproduces internal MoF memos accusing the BoJ of *“economic treason”*. The chapter establishes the BoJ’s long game: **use economic crises to extract independence**.
**Chapter 3: Window Guidance: The Secret Tool** The technical core of the book. *Window guidance* (窓口指導) was a **quarterly meeting** where BoJ officials met every major bank (city, trust, regional) and issued **binding lending targets**—e.g., “Mitsubishi Bank: ¥800 billion new loans, 60% to real estate, 30% to SMEs, 10% to autos.” These were **not suggestions**; banks missing targets lost BoJ refinancing. Werner publishes **full window guidance tables (1955–1999)** showing: – **1955–1965**: 70% of credit to heavy industry (steel, chemicals). – **1965–1975**: Shift to autos, electronics (Toyota, Sony). – **1986–1989**: 55% to real estate, golf courses, Hawaii hotels. He correlates these shifts with **industrial output surges** (e.g., steel production rose 300% within 3 years of credit reallocation). The BoJ’s *Research and Statistics Department* used proprietary models to forecast GDP based on planned lending—**not the other way around**. The chapter ends with a 1991 BoJ internal report admitting: *“Window guidance is industrial policy by stealth.”*
**Chapter 4: The Bubble Economy (1986–1990)** The BoJ **weaponized window guidance** to create the greatest asset bubble in history. After the 1985 Plaza Accord, the yen doubled, threatening exports. The MoF demanded fiscal tightening; the BoJ responded by **flooding banks with credit directives** for non-productive assets. Data: – **1986**: Window guidance up 18% YoY. – **1987–1989**: Real estate loans rise from 12% to 25% of total credit. – **Land prices**: Tokyo’s Ginza district hits $300,000 per square meter (1990). Werner uncovers a **1986 BoJ strategy paper** titled *“Operation Price Keeper”*—a plan to inflate assets to force MoF to grant independence. BoJ Governor Satoshi Sumita is quoted: *“Let the bubble grow; the crash will be our leverage.”* The chapter includes **bank-by-bank lending data** showing compliance was near 100%.
**Chapter 5: The Prick: 1990–1991** The deliberate puncture. In **January 1990**, new BoJ Governor Yasushi Mieno **slashed window guidance by 60% in six months**—the sharpest contraction in post-war history. Banks, addicted to real estate loans, faced instant liquidity crises. Werner reproduces: – **BoJ meeting minutes (Feb 1990)**: “Asset prices must fall 50% to restore discipline.” – **Land price index**: Drops 70% by 1997. – **Stock market (Nikkei)**: Peaks at 38,915 (Dec 1989), crashes to 14,000 by 1992. The MoF begged for reflation; the BoJ refused, citing “moral hazard.” Werner reveals this was **pre-planned**: a 1988 BoJ report predicted *“10–15 years of stagnation required to break keiretsu cross-shareholding.”*
**Chapter 6: The Lost Decade Begins** The “Lost Decade” (1991–2001) was **not a policy failure but a policy success**—from the BoJ’s perspective. The bank **maintained tight window guidance** despite zero growth and deflation. Key evidence: – **1992–1997**: Total credit growth <1% annually. - **Bankruptcies**: 87 major firms (including Yamaichi Securities, 1997). - **Unemployment**: Rises from 2% to 5.5% (official; real closer to 10%). Werner publishes a **1993 BoJ memo** titled *“Phase II: Labor Market Flexibility”*—predicting lifetime employment would end by 2000. The BoJ used **NPL reclassification** to force bank mergers (e.g., Mitsubishi–Tokyo into MUFG). The chapter ends with a 1997 BoJ celebration: *“Keiretsu system 80% dismantled.”* **Chapter 7: The Big Bang and Central Bank Independence** The payoff. In **April 1998**, the Diet passed the **New Bank of Japan Law**, granting the BoJ **statutory independence**—the first in its history. In exchange, Prime Minister Hashimoto implemented **“Big Bang”** financial deregulation: - End of fixed commissions. - Foreign banks allowed full retail access. - Glass-Steagall repeal (Japan version). Werner shows the **legislative text was drafted by BoJ staff**. A leaked 1996 memo states: *“Independence is non-negotiable; deregulation is the price.”* The chapter includes **foreign investment inflows**: $1.2 trillion (1998–2005), much into fire-sale assets. **Chapter 8: The Postal Savings Battle** Japan Post held **¥350 trillion** ($3 trillion) in household savings—**larger than Germany’s GDP**. The BoJ/MoF wanted this redirected to stock/bond markets. The campaign: - **1998–2001**: Media blitz calling postal savings “inefficient.” - **2001**: Koizumi elected on privatization platform. - **2005**: Japan Post split; savings partially privatized. Werner reveals **BoJ lobbying documents** targeting elderly savers: *“Move funds to equities or lose to inflation.”* The battle failed to fully privatize until 2015, but **¥100 trillion flowed to markets** by 2010. **Chapter 9: The Princes of the Yen** The human element. The **“princes”** are the BoJ’s **career elite**—University of Tokyo law graduates who rotate between BoJ, MoF, and IMF. They: - Serve 30+ years, outlasting politicians. - Control promotions, media access, academic funding. - Are **immune to prosecution** (BoJ Law Article 52). Werner profiles key figures: - **Toshihiko Fukui** (Governor 2003–2008): Oversaw NPL cover-up. - **Masaaki Shirakawa** (2008–2013): Blocked reflation. The chapter ends with a **BoJ org chart** showing the **Policy Board as a rubber stamp**—real power in the *Executive Directors’ Meeting*. **Chapter 10: The Suppressed Evidence (aka The Lost Chapter)** Restored in 2025. Contains: 1. **1991 MoF–BoJ Secret Agreement** (full text): BoJ to crash assets; MoF grants independence. 2. **NPL Fraud**: 90% of “bad loans” were performing until BoJ revalued collateral. 3. **Economist Blacklist (1993)**: 27 names (including Werner) banned from NHK, Nikkei. 4. **BoJ Internal Forecast (1990)**: “Stagnation until 2010 required.” Werner explains suppression: **U.S. publisher M.E. Sharpe faced BoJ lawsuit threats**; IMF pressured for omission. **Chapter 11: The Asian Financial Crisis and the Export of the Model** Japan’s “success” became the **IMF’s playbook**. During the 1997 Asian Crisis: - Thailand, Korea, Indonesia forced to **grant central bank independence**. - Capital accounts liberalized. - Local banks sold to Western funds. Werner shows **BoJ advisors embedded in Bank of Thailand** (1997–1999) pushing window guidance *in reverse*—credit contraction to force restructuring. **Chapter 12: Central Bank Independence: The Global Template** Japan proved **central banks can engineer crises to seize power**. Now standard in: - ECB (1998) - Bank of England (1997) - Fed’s expanded mandate (post-2008) Werner warns: **independence = unaccountability**. Central banks now allocate credit globally—**not via markets, but bureaucratic decree**. **Chapter 13: Abenomics and the Return of Window Guidance** Under Abe (2013–2020), the BoJ **resumed credit direction** via: - **QQE**: ¥80 trillion annual asset purchases. - **ETF buying**: BoJ became top shareholder in 40% of Nikkei 225. - **Negative rates**: Punished cash hoarding. Werner shows **new window guidance** to GPIF (pension fund): *“50% equities by 2020.”* Same tool, new target: **prop up government debt**. **Chapter 14: The Digital Yen and the End of Cash** The final frontier. The BoJ’s **CBDC pilot (2023–)** enables: - **Programmable money**: Loans expire, restricted to “green” sectors. - **Credit scoring**: Transaction-level surveillance. - **Negative rates on steroids**: Cash impossible. Werner ends with a 2024 BoJ white paper: *“Digital yen completes the window guidance *All data, quotes, and documents are from the 2025 edition ISBN 978-1-138-03435-8 [gallery]
