The Japanese yen has fallen further, reaching the “4.7 range” against the Hong Kong dollar and setting a nearly 40-year low. This historic moment, with the Japanese yen hitting a 40-year low, has thrilled travelers planning trips to Japan while leaving investors deeply concerned about the Japanese yen outlook. When did this astonishing decline begin? The reasons behind it are highly complex, ranging from daily Japanese yen-to-Hong Kong dollar exchange rate quotations to global central bank policy developments, all of which have kept the market on edge. Faced with such volatility in the foreign exchange market, many people cannot help but ask: Will the Japanese government intervene again? This article provides a comprehensive analysis of the reasons behind the yen’s sharp decline and its future outlook, along with practical 2026 strategies for travelers and investors.
To understand the future of the Japanese yen, it is essential to first grasp the current data and its historical trajectory. This section provides a quick review of the yen’s key exchange rate levels and major events.
As of late July 2026, the Japanese yen continued to hover near historic lows:

This round of yen depreciation did not happen overnight, but unfolded through several key stages of decline:
After understanding the surface-level effects of yen depreciation, we need to explore the core driving forces behind it more deeply. Simply put, capital always flows toward places offering higher returns, and the current global monetary policy environment has created a perfect storm for yen depreciation.
This is the most fundamental and direct reason. The monetary policies of the world’s major central banks are currently moving in sharply different directions:
This enormous interest rate differential has fueled the popularity of “carry trades”. Investors borrow large amounts of yen at almost zero cost, convert them into higher-yielding currencies such as the US dollar, and invest them to earn stable returns from the interest rate gap. This process involves continuous selling of the yen and buying of the US dollar, naturally placing heavy downward pressure on the yen exchange rate.
The market focuses not only on current interest rates, but also on expectations for future policy. Although Japan’s core inflation has exceeded the 2% target for several consecutive months, the Bank of Japan has remained cautious on the path toward monetary policy normalization. Governor Kazuo Ueda has repeatedly emphasized that further interest rate hikes will only be considered once “sustainable and stable inflation” is evident. This “dovish” stance has led the market to widely believe that the Bank of Japan will not tighten monetary policy quickly or substantially. Therefore, even occasional hawkish remarks have been unable to reverse the market’s long-term bearish expectations for the yen. You can gain a deeper understanding of the Bank of Japan’s policy developments through professional websites such as MacroMicro.
When the yen depreciates too rapidly and impacts the domestic economy (particularly import costs), whether the Japanese government will intervene becomes the market’s main focus.
Before using foreign exchange reserves to intervene directly, officials from Japan’s Ministry of Finance, such as Finance Minister Shunichi Suzuki or Vice Minister of Finance Masato Kanda, usually begin with “verbal intervention”. Through the media, they may state that they are “closely monitoring the foreign exchange market”, “will not rule out any options”, or are “concerned about excessive exchange rate volatility”. The purposes of these statements are:
However, the effects of “verbal intervention” are usually temporary. If the underlying causes, such as the interest rate differential, remain unchanged, the market will quickly absorb these remarks and resume its original trend.
The Japanese government has indeed intervened in the market several times in recent years:
Historical experience shows that intervention can effectively curb speculative sentiment in the short term, but it is difficult to reverse a long-term trend driven by differences in monetary policy. It acts more like a “brake” than a “steering wheel”.
The market generally believes that the Japanese government does not intervene to defend a specific exchange rate level, but focuses more on the “speed of depreciation”. If the exchange rate fluctuates sharply within a short period, the likelihood of intervention will increase significantly. Market experts are currently watching the following potential intervention trigger points:
However, whether intervention ultimately occurs will still depend on the political and economic environment and market conditions at the time.
Faced with the yen’s once-in-40-years low, people in different circumstances should adopt different approaches. Whether you are a traveler, investor, or business owner, you need to formulate a clear strategy.
For travelers planning to “return home” to Japan, the yen’s depreciation is undoubtedly excellent news. However, the question is: Should you exchange the entire amount now or wait a little longer?
Do not try to predict the absolute bottom. It is advisable to start three to six months before your planned trip, set a budget, and divide it into three to five batches. Whenever the exchange rate appears favorable (for example, when it falls below 4.8 against the Hong Kong dollar), exchange one batch. This can effectively average your cost and reduce the risk of exchanging the entire amount at a relatively high level. You can also refer to a yen exchange strategy guide to develop a more detailed plan.
For investors, sharp fluctuations in the yen present both risks and opportunities.
For businesses, exchange rate stability is more important than appreciation or depreciation alone.
In summary, the yen’s fall to a 40-year low is the result of multiple overlapping factors, including diverging global monetary policies and the wide interest rate gap between the US and Japan. This exchange rate storm has created unique opportunities and challenges for people in different circumstances. Whether you are a traveler preparing to “return home” and enjoying the shopping benefits brought by the exceptionally favorable exchange rate, or an investor closely monitoring market developments and seeking trading opportunities, it is essential to understand the reasons behind this round of yen depreciation and formulate an appropriate response strategy. Looking ahead, the market will continue to focus on US inflation data and the Bank of Japan’s policy developments. Everyone concerned about the yen outlook is advised to remain flexible and continue monitoring developments in order to make the decisions that best serve their interests amid this historic shift in exchange rates.
A: The main advantages are higher foreign exchange gains and share prices for large export companies, as well as increased foreign tourism, which stimulates the tourism industry. The disadvantages are higher costs for imported energy, raw materials, and food. For import-dependent businesses and ordinary households, this significantly increases financial pressure and may lead to “imported inflation”.
A: During periods of yen depreciation, using a credit card that offers high rewards on overseas spending is generally more cost-effective. Credit card exchange rates are usually close to spot rates and more favorable than cash exchange rates. After rewards are included, the overall cost may be lower than paying in cash. However, it is still advisable to exchange a small amount of cash for emergencies or for purchases at cash-only stores.
A: Against the backdrop of a strong US dollar, most non-US currencies are under pressure. Investors can monitor currencies that are highly correlated with commodity prices, such as the Australian dollar (AUD) and Canadian dollar (CAD), as well as other Asian currencies facing similar interest rate differential pressure, such as the South Korean won (KRW) and New Taiwan dollar (TWD). In addition, the European Central Bank’s (ECB) policy direction has also made the euro (EUR) a key market focus.
A: The Bank of Japan holds eight scheduled monetary policy meetings each year. You can check the Bank of Japan’s (BOJ) official website directly for the most accurate annual meeting schedule. The interest rate decision and policy statement are usually announced around noon on the final day of the meeting, followed by the governor’s press conference in the afternoon. These are closely watched market events.
