162 yen: The currency lament of an empire

EX.IO Research

When “safe assets” are no longer safe

On June 30, 2026, in the Tokyo foreign exchange market, the USD/JPY rate reached 162.36. And on the same day, Bitcoin recovered to $60,000.

The last time the yen was in this position was in 1986. That year, the Chernobyl nuclear power plant exploded, Microsoft had just gone public, and the aftermath of the Plaza Accord was still reshaping the global economic landscape. Thirty-nine years later, the yen has returned to the same place—but this time, it is not appreciating, it is falling.

For domestic Japanese savers, this means that nearly one-third of their hard-earned purchasing power has evaporated in less than five years. For wealth holders worldwide, this is a textbook case of how the narrative of “safe assets” is slowly collapsing.

This is no coincidence. This is a currency experiment spanning forty years, reaching its climax.

Chapter 1: From the Top of the World to the Liquidity Trap — 40 Years of the Japanese Economy

The Plaza Agreement: A “Boom Designed for Us.”

On September 22, 1985, the United States, Japan, West Germany, France, and the United Kingdom signed an agreement at the Plaza Hotel in New York to coordinate intervention in the foreign exchange market and promote the depreciation of the dollar. The yen surged from 1 dollar to 240 yen in two years to 120 yen—doubling in appreciation.

For Japan at the time, this was a “great power pass.” The yen has strengthened, and Japanese companies’ overseas purchasing power has soared. Mitsubishi bought Rockefeller Center, and Sony acquired Columbia Pictures. The whole world is talking about being the “number one in Japan.”

But the Plaza Accord is also a slow-motion bomb.

To hedge against the export impact of yen appreciation, the Bank of Japan lowered interest rates from 5% to 2.5% in1986-1987. Cheap capital flows into the stock market and real estate. On December 29, 1989, the Nikkei 225 index reached 38,957 points—a record that remains unbroken to this day 。

Bubble burst: a thirty-year balance sheet repair

In 1990, the bubble burst.

The Bank of Japan urgently raised interest rates to burst the bubble, but it was too late. The stock market plunged60%, and commercial real estate prices dropped by more than 70%. Businesses and families are in a “balance sheet recession”—not because they have no money, but because they don’t dare to spend, don’t dare to borrow, and only dare to repay debts.

Over the next thirty years, Japan experienced almost every “impossible” described in economics textbooks:

• Zero interest rate policy (ZIRP): Pioneered in the zero-interest rate era in 1999
• Quantitative easing (QE): In 2001, it became the world’s first central bank to implement QE
• Negative interest rates: In 2016, the policy rate was reduced to -0.1%.
• Yield Curve Control (YCC): Keeps the 10-year Treasury yield near 0%.
• Central Bank Directly Buys ETFs: The Bank of Japan Becomes the Largest Shareholder of the Tokyo Stock Exchange

Each of these is a “first” in the history of global central banks. Each time, attempts are made to break deflation expectations. Every time, it ended in failure.

The legacy of Abenomics: the limits of the printing press

In 2013, Shinzo Abe came to power with “three arrows”: bold monetary policy, flexible fiscal policy, and structural reforms.

The first two arrows were fired. The Bank of Japan’s balance sheet soared from 160 trillion yen before Abe took office to over 760 trillion yen (about 4.7 trillion USD)—surpassing Japan’s GDP 130%。

The yen depreciated from 1 dollar per 80 yen in 2012 to 125 yen in 2015. Export companies cheered, but the purchasing power of ordinary households was slowly eroded.

And the third arrow—structural reform—has never truly been launched.

 

Chapter 2: 2026, the Tipping Point

The paradox of the BOJ rate hike

On June 16, 2026, the Bank of Japan raised its policy rate to 1.0%—the highest level in 31 years since 1995 。

Logically, interest rate hikes should support the exchange rate. However, after the rate hike, the yen not only failed to strengthen, but instead accelerated its depreciation from 155 to 162.36 within two weeks.

The market is telling the BOJ a harsh truth: a 1% interest rate is still ridiculously low globally. The Fed’s policy rate is at 4.25-4.50%, with spreads exceeding 350 basis points. As long as this spread exists, shorting the yen is the most crowded and least imaginative transaction globally.

Red alert for the banking system

On June 28, 2026, Nikkei Asia reported disturbing news: several of Japan’s largest banks are seeking assistance from the government and the BOJ— They have faced difficulties in raising dollar funds for their promised U.S. investment projects.

The weaker the yen, the higher the cost for Japanese institutions to hold dollar assets. And the investments they promise in the U.S.—as part of the U.S.-Japan tariff negotiations— amount to hundreds of billions of dollars.

This is a typical “dollar trap”: Japan is being asked to export capital, but its currency is depreciating at the fastest rate in 39 years. Each devaluation makes the next dollar financing more expensive.

Circle + Nomura: A digital patch for the fiat currency system

On June 25, 2026, Circle, the world’s second-largest stablecoin issuer, announced a partnership with Nomura Securities to  provide instant foreign currency settlement services to Japanese companies as early as 2027 。

This news story is usually framed within the narrative framework of “crypto adoption.” But against the backdrop of the yen’s 39-year low, it really tells a different story: Japan is searching for a backdoor to escape the traditional foreign exchange system.

Stablecoins essentially bypass the existing interbank settlement system. When a Japanese company settles cross-border via USDC instead of the SWIFT network, it saves more than just fees—it bypasses the entire proxy bank-based dollar clearing system.

That’s also why Circle chose Nomura: not Coinbase, not Binance. It is Japan’s largest securities firm and an institutional player with 30 trillion yen in client assets.

$3.5 billion in wasted effort

On April 30, 2026, Japan’s Ministry of Finance (MOF) intervened in the foreign exchange market.

According to market analysis agencies, Japanese authorities invested about $35 billion in a single day in an attempt to support the yen’s exchange rate. This was one of the largest single-day interventions in Japan’s history.

The result? The yen briefly rebounded to 155 before continuing to decline. Two months later, it not only returned to pre-intervention levels but also hit a 39-year low.

Market analysis platform Lambda Finance pointed out in a May report: “MOF will not tolerate USD /JPY consistently breaking above 160 — that is the de facto intervention floor.” ”

Two months later, that bottom line was mercilessly broken.

This is not a failure of intervention strategies. This reveals a deeper law: in an era of global capital free flow, a country’s foreign exchange reserves facing a daily $7.5 trillion foreign exchange market are like a glass of water trying to extinguish a forest fire.

Chapter 3: The Mirror of Bitcoin

Yen vs Bitcoin: One picture speaks louder than a thousand words

Let’s look at a simple set of numbers:

Time	USD/JPY	BTC/USD	1 BTC = ? JPY	Can you buy it for 100 million yen? BTC
Early 2013	~87	~13	~1,131	~88,400
At the end of 2017	~113	~19,000	~2,147,000	~46.6
March 2020	~108	~5,000	~540,000	~185
July 2024	~161	~65,000	~10,465,000	~9.6
July 2026	~162	~60,000	~9,720,000	~10.3

Over the past 13 years, the purchasing power of 100 million yen in Bitcoin has shrunk from 88,400 BTC to 10 BTC. This is not a fluctuation; it is an intergenerational transfer of currency value.

Data sources: CoinGecko historical prices (BTC/USD), Investing.com historical exchange rates (USD/JPY). Data for July 2026 is a real-time snapshot.

The yen is depreciating, but Bitcoin is not cheaper when priced in yen—because Bitcoin’s own dollar price fluctuations far outweigh the yen’s buffer effect. For Japanese investors, the core variable that determines profit or loss in BTC holdings is not the direction of the yen, but the global pricing of BTC itself.

Bitcoin is not “digital gold,” but rather the “exit key for sovereign currency.”

Traditional narratives position Bitcoin as “digital gold”—a tool for hedges against inflation. But this framework underestimates the true meaning of Bitcoin.

Bitcoin is not hedged against inflation. It hedges against the unsustainability of the monetary system.

Japan presents the most extreme cases: no hyperinflation, no regime change, no war on its own. Everything seems very “stable.” But beneath the apparent stability, central bank balance sheets have ballooned to 130% of GDP, interest rates have hovered near zero for a quarter of a century, and the yen has returned to the same low point after nearly forty years.

This is the “boiling frog” style of currency devaluation. It’s not dramatic, but just as deadly.

For Japanese depositors—especially the elderly holding large amounts of cash and Japanese government bonds—Bitcoin offers something they cannot find within the banking system: an exit button.

An asset unaffected by any central bank balance sheet. An asset that cannot be diluted by QE. An asset whose supply is mathematically locked.

This is not about “faith” in cryptocurrency. It’s about realizing: in a world where all central banks are competing to print faster, holding an asset that can’t be printed isn’t speculation—it’s risk management.

Chapter 4: What Wealth Holders Mean

Japan is not an isolated case; it is a pioneer

Japan’s currency dilemma has its own unique characteristics in terms of demographic structure and debt dynamics. But the pattern it reveals — aging + high debt + central banks forced to continue accommodating → long-term currency devaluation — is the trajectory almost all developed economies are on.

The yen in 2026 offers a thought-provoking reference for observing the currency outlook of other developed economies.

For PI clients, the core question is not “Is Bitcoin too volatile?” but rather:

How many assets in your portfolio are truly irdilutive?

Real estate? — Influenced by policy, taxation, and demographic structure. Gold? — Annual mining volume is about3,000 tons, with an additional supply of 1.5-2%. Government bonds? — Nominal value is guaranteed, but purchasing power is not. Stocks? —— The company can issue additional shares. Indexes can be swapped for ingredients.

Bitcoin is the world’s first and currently the only large-scale financial asset that cannot be systematically diluted by any institution or mechanism.

Allocation Framework (not investment advice, for reflection only).

Without changing the investment recommendation red line, here are some analytical perspectives worth considering:

Different investors position Bitcoin differently based on their own risk tolerance and asset structure—some see it as a small tail risk hedge, while others classify it as a value hedging tool parallel to gold. Each choice depends on personal financial situations, investment goals, and risk preferences, with no universal standard answer.

The above is only an abstract explanation of the asset allocation approach and does not constitute advice or recommendations for any asset or ratio. Any allocation decisions should be based on personal financial status and consult licensed professional advisors.

Chapter 5: Looking Ahead — When Consensus Is Broken

When the blind spot of consensus is revealed

Forward-Looking Statements: The following discussions regarding yen exchange rates, Bitcoin prices, and market trends are based on third-party source data and current market conditions, and do not constitute predictions, guarantees, or commitments regarding future prices, exchange rates, or market trends. Historical performance and current trends do not represent future results.

In May 2026, the world’s major investment banks’ year-end forecasts for USD/JPY are as follows (Lambda Finance summary):

Institutions	USD/JPY forecast for the end of 2026
Goldman Sachs	142
JPMorgan Chase	145
Morgan Stanley	146
Citi	148
UBS	144
Nomura	140
Deutsche Bank	152 (most bearish on the yen).
Seller consensus median	~145

Just two months later — July 2, 2026 — USD/JPY stood at 162.55.

This is not just prediction bias. This is a structural failure of the entire seller’s consensus.

Even Deutsche Bank—the 7 most bearish on the yen— is 10 yen below the current actual level. Meanwhile, Nomura, which is most bullish on the yen (forecasted 140), is more than 22 yen behind reality.

What happened? The core assumption of the consensus is: Fed rate cut + BOJ rate hike = interest rate spread narrowing = yen strengthening. This assumption holds logically, but it overlooks a key variable: the inertia of capital flows. The scale of global investors’ short positions in the yen built over the past three years is so large that even if the spread narrows from 530 basis points to 350 basis points, it would still be far from enough to trigger large-scale liquidations.

Three futures

Based on existing data and structural strength, we can outline three possible paths:

Path One: Intervention triggers a reversal (probability: low).

Japan’s Ministry of Finance and the Federal Reserve have launched large-scale coordinated interventions, while the BOJ unexpectedly raised rates by more than 50 basis points. The yen quickly rebounded into the 140-150 range.

Lambda Finance warned in its May report: “The 140 arbitrage closing proof for August 2024 could be reached within days.” But such a reversal requires extreme conditions — cooperation from the U.S. side, and in the current US-Japan trade negotiations, there is great uncertainty over whether Washington is willing to help Tokyo support the yen.

Path 2: Slowly slide into the abyss (Probability: Medium to high).

The BOJ continues to raise rates slowly at a rate of 25 basis points per cycle, and amid repeated interventions and rebounds, the yen is trending toward 170-180. The independent model LongForecast’s USD/JPY technical forecast suggests the yen could reach 172 by the end of 2026, with a mid-2027 breakout 180。

Bloomberg had already issued warning signals in its report at the end of 2025: “Bearish sentiment on the yen will grow louder in 2026 because the BOJ‘s policy path is too cautious.” ”（“Yen Bearish Voices Build for 2026 on Cautious BOJ Policy Path”）

This promise is being fulfilled.

Path Three: Black Swan (Probability: low, but huge consequences).

Major turmoil in Japan’s government bond market may be underway, or systemic pressure on the Japanese banking system due to the dollar funding gap. At this point, the BOJ will be forced to choose between “preserving the exchange rate” and “protecting the bond market/banks” — Historically, central banks have always chosen the latter.

For yen holders, the endpoint of Path Two and Path Three is the same: the continued evaporation of purchasing power.

Institutional voices

“Directionality is positive for the yen on a 12-month scale, but the short term will be chaotic. ” — Consensus among multiple G10 forex trading platforms (Lambda Finance, May 2026 ).

“Bearish sentiment on the yen will grow louder in 2026, as the BOJ’s policy path is overly cautious. ” — Bloomberg (December 25, 2025).

“MOF will not tolerate USD/JPY consistently breaking above 160 — that is the de facto intervention floor. ” — Lambda Finance Forex Strategy Consensus (May 2026).

“If the UEDA rate hike exceeds market pricing, USD/JPY will fall below 140. ” — Multiple G10 forex trading platforms

Four quotes from different points in time. Looking back today, the most striking paragraph is the third paragraph:”160 is the intervention bottom line”—two months later, 162.

This is precisely the fundamental dilemma of the fiat currency system: the central bank can speak harshly to the market, but the market does not need to trust the central bank. The market only needs to calculate the spread.

What it means for Bitcoin

If the yen moves toward 180-200 in the next 2-3 years (as independent forecasting models warn), then Bitcoin’s price in yen will no longer be 9.8 million yen—but 1,100-1,200 Tens of thousands of yen, or even more.

The above is a hypothetical simulation based on third-party forecasting models and current spread trends. Real exchange rates and prices depend on multiple variables, including but not limited to the BOJ policy path, Federal Reserve interest rate decisions, global capital flows, and geopolitical events.

For Japanese investors, this is not about whether Bitcoin will rise. This is about whether the yen will continue to fall. And data from the past 40 years provides an answer that cannot be ignored.

Epilogue: The final chapter of the Plaza Agreement

The 1985 Plaza Accord marked the beginning of the yen’s appreciation. The yen’s 39-year low in 2026 may be one of the final chapters of this story.

But the significance of this story goes beyond Japan.

It reminds us that the “stability” of money is an illusion, a balance artificially maintained by central banks during specific historical windows. When demographics, debt levels, and global capital flows shift simultaneously, this balance breaks down.

Bitcoin is not perfect. But it offers an option outside the fiat currency system. For savvy wealth holders, the option itself is the most valuable asset.
