The Japanese yen has shown a distinct depreciating trend since late September 2012. From September 28, 2012, to 15:32 on July 13, 2026, the yen's exchange rate against the US dollar fell from 77.57 to 162.17, a depreciation exceeding 109%.
In a recent Japanese drama, a character meticulously times her supermarket trip to the moment discount stickers are applied, a scene reflecting a shrewd survival philosophy in today's Japan. This micro-level pursuit of value for money serves as a footnote to an era of eroding purchasing power for the yen.
The Long Slide
The yen's pronounced depreciation began in late September 2012 and has persisted. Since late June 2026, the yen has repeatedly breached the 162 level against the dollar, reaching 162.17 by mid-July. This marks a decline of over 109% from its September 2012 level.
This persistent weakness has reignited Japan's imported inflation. Data from the Bank of Japan shows that in May 2026, the year-on-year increase in the import price index, denominated in yen, hit its highest level since November 2022.
Despite several rounds of foreign exchange intervention by Japanese authorities between 2022 and 2026 involving selling dollars and buying yen, the currency's gains were typically short-lived, with the yen quickly giving back its advances.
Gu Fengda, Chief Analyst at Guosen Futures, noted that domestically, Japan is trapped in a cycle where yen depreciation raises import costs, keeps imported inflation high, and deters the central bank from aggressive rate hikes. "Unilateral intervention in the yen forex market is like trying to put out a cart fire with a cup of water against the massive US-Japan interest rate differential, making it difficult to reverse the depreciation trend."
On June 16, the Bank of Japan raised its policy rate from 0.75% to 1.0%, its highest level in 31 years. However, with the US Federal Reserve's rate held between 3.5% and 3.75%, a gap of nearly 300 basis points remains. Hu Jie, a professor at Shanghai Advanced Institute of Finance and a former senior economist at the Fed, stated that as long as this interest rate differential persists, the yen's downtrend is unlikely to abate.
Yang Chao, Chief Strategist at China Galaxy Securities, believes that for the yen to end its decline and stabilize, a triple repair of monetary policy, economic fundamentals, and the external environment is necessary, with the core being "reversing the interest rate disadvantage and economic weakness."
Analyst Perspectives and Forecasts
In a July 3 research report, Goldman Sachs adjusted its 12-month forecast for the USD/JPY exchange rate to 165, up from a previous estimate of 155. UBS Global Wealth Management's Chief Investment Office also made a slight upward adjustment to its year-end 2026 target to 156 from 154. However, UBS noted that as the US-Japan yield gap continues to narrow and given the current high level of short yen positions, the yen may still have an appreciation trend against the dollar ahead. Mitsubishi UFJ Financial Group expects the yen to trade around 160 against the dollar in Q3 2026 before recovering to 154 by Q2 2027.
Gu Fengda advised that retail investors should avoid one-way shorting of the yen, as downside below 162 is limited while rebound risks are accumulating. For investors considering Japanese assets, he suggested that allocations to export-oriented leaders like Toyota and Sony could be relatively favorable, while domestic demand-oriented sectors should be reduced or avoided.
Roots of the Decline
The trend is often traced back to the launch of "Abenomics" in 2012, a key feature of which was ultra-loose monetary policy. In April 2013, the Bank of Japan announced it would increase the monetary base by about 60-70 trillion yen annually, a significant acceleration from previous years, and later introduced a negative interest rate policy.
Hu Jie explained that the existence of the US-Japan interest rate differential creates a persistent arbitrage opportunity, keeping pressure on the yen. "Only when market expectations point to the interest rate gap largely disappearing is it possible to stop the sustained depreciation of the yen."
The aggressive Fed hiking cycle from March 2022 to July 2023, which pushed US rates from near zero to over 5%, while Japanese rates remained negative, widened the differential to over 500 basis points at its peak. Although the gap has since narrowed by over 200 basis points as the US began cutting rates and Japan started hiking, the yen's depreciation has continued.
An IMF report from April 2026 noted that since mid-2025, Japan's Ministry of Finance has emphasized that the yen exchange rate has decoupled from the narrowing US-Japan rate differential, with speculative trading being a significant factor driving rapid currency fluctuations.
Economic Impact and Consumer Strain
For importers, the weaker yen means higher costs. One importer noted that a product priced at $1 now costs over 11% more in yen than it did a year ago, leading to challenges like reduced order frequency and pressure from Japanese suppliers to renegotiate prices.
The depreciation directly fuels imported inflation, which is particularly acute for a nation heavily reliant on imports for energy, food, and raw materials. This has led to broad-based price increases while wage growth lags, squeezing real incomes and creating stagflationary pressures of inflation coupled with weak domestic demand.
Consumers are feeling the pinch, with reports of "consumption downgrades." For instance, high-quality Australian beef has become scarce in supermarkets, replaced by more affordable but less desirable alternatives from other countries, with prices still significantly higher than before.
Ineffective Intervention
Faced with the yen's slide, the Japanese government has recently appeared to step back from intervention. Data showed zero intervention from late May to late June 2026.
This hands-off approach follows the failure of previous massive interventions to produce lasting results. In late April to late May 2026, Japan conducted its largest single-month forex intervention on record, spending over 11.73 trillion yen to buy yen. While the yen initially strengthened by over 2.6%, it soon resumed its depreciating trend.
Yang Chao argued that both historic rate hikes and record forex intervention have failed because they are short-term countermeasures that cannot reverse the medium-to-long-term interest rate differential, market trading logic, and fundamental economic weaknesses. Market confidence in Japan's policy resolve and economic prospects remains low, viewing its rate hikes as passive and gradual rather than proactive tightening.
He further stated that forex intervention is merely a short-term sentiment tool. Japan's large-scale interventions are essentially one-way,存量式 market hedges that can only temporarily slow the pace of depreciation and repair extreme market sentiment, not change cross-border capital flow trends. Once intervention wanes, bearish forces quickly return.
Looking back at interventions from 2022 to 2024, the yen's gains typically lasted only a few weeks before being erased.
Looking Ahead
Outlooks among major financial institutions vary. Goldman Sachs remains bearish, citing lower recession risks, lingering fiscal concerns, elevated US Treasury yields, and a gradual BoJ hiking path as factors sustaining pressure on the yen.
Mitsubishi UFJ Bank holds a more neutral to cautiously optimistic view, expecting a gradual yen recovery into 2027 as US yields retreat and the BoJ continues to hike. UBS has also adjusted its forecasts, pushing back its expected Fed rate cut timeline and slightly raising its near-term USD/JPY targets.
