The Bank of Japan (BOJ) has historically ended its long-standing negative interest rate policy and officially launched its first rate hike in seventeen years. This not only symbolizes a key step toward the normalization of Japan’s monetary policy, but also carries far-reaching implications for global financial markets. This major shift is based on confidence that Japan’s economy can sustainably achieve its 2% inflation target. Are you confused about why the Japanese yen weakened instead of strengthening after the Bank of Japan raised rates? Or are you trying to understand the future direction of Japanese stocks following the BOJ policy meeting? This article will comprehensively analyze the reasons behind Japan ending negative interest rates, the immediate market impact, and provide professional insights into future investment strategies.
To understand the historical significance of this policy shift, we must first look back at why the Bank of Japan implemented such an extreme monetary policy in the first place, and what factors have now prompted policymakers to change direction.
After the collapse of Japan’s asset bubble in the early 1990s, the country entered decades of economic stagnation and deflation, a period commonly referred to as the “Lost Thirty Years”. Deflation refers to a prolonged decline in prices, causing consumers to delay purchases in anticipation of lower future prices, while businesses reduce investment due to shrinking profits, creating a vicious cycle. To combat this persistent economic challenge, the Bank of Japan introduced its “Negative Interest Rate Policy (NIRP)” in 2016.
Simply put, under negative interest rates, commercial banks placing excess funds at the central bank would not receive interest income, but instead have to pay a “storage fee” to the BOJ. The objectives of this policy were very clear:
Over time, the global economic environment changed dramatically. In recent years, factors such as supply chain disruptions, the Russia-Ukraine conflict, and rising energy prices created widespread global inflationary pressure, and Japan was no exception. The sustained rise in prices gave the Bank of Japan an opportunity to escape deflation. However, for inflation to remain “sustainably” stable at the 2% target, rising prices alone were insufficient. The key was whether wage growth could keep pace and create a healthy “wage-price” upward spiral.
A Healthy “Wage-Price” Cycle Became the Key Foundation Behind the Bank of Japan’s Decision to Raise Rates.
The final catalyst came from Japan’s annual labor-management wage negotiations, known as “Shunto”. According to preliminary data from Japan’s largest labor union federation, Rengo, average wage growth in 2026 reached 5.28%, marking the highest increase in 33 years. This historic wage growth gave the Bank of Japan sufficient confidence that Japan’s economy had developed endogenous growth momentum capable of supporting moderate inflation, making it the right time to normalize monetary policy.
During this historic BOJ policy meeting, the Bank of Japan not only raised the policy interest rate from -0.1% to a range between 0% and 0.1%, but also announced a series of major policy adjustments, officially dismantling the framework of the ultra-loose monetary policies implemented over the past decade:
Together, these measures mark the official end of the Bank of Japan’s long-running large-scale monetary easing experiment and signal the beginning of a completely new phase.
As the world’s third-largest economy and a major creditor nation, Japan’s shift in monetary policy will undoubtedly trigger a series of chain reactions. From the Japanese yen exchange rate to global capital flows, markets around the world will feel the shockwaves caused by “Japan ending negative interest rates”.
Many people intuitively believe that when a country raises interest rates, its currency should strengthen. However, after the Bank of Japan announced rate hikes, the Japanese yen weakened against the US dollar and USD/JPY broke above the 150 level. Why did this happen?
There are three main reasons:
Despite Japan Raising Rates, the Massive US-Japan Interest Rate Gap Remains the Primary Driver of the Japanese Yen Exchange Rate.
The shift in monetary policy has structural effects on different sectors of the stock market.

Over the past decade, due to Japan’s ultra-low interest rates, the Japanese yen became the world’s primary “funding currency”. International speculators borrowed Japanese yen at nearly zero cost, then converted it into higher-yield currencies such as the US dollar to invest in overseas high-yield assets. This strategy became known as the “yen carry trade”.
Rising Japanese interest rates may trigger a large-scale unwinding of yen carry trades.
Now that the Bank of Japan has raised interest rates, the cost of borrowing Japanese yen has begun increasing. Although the current pace of rate hikes remains limited, it has already sounded the alarm for this enormous carry trade market. If Japan continues raising rates in the future, it may accelerate the unwinding of carry trades (meaning investors would sell overseas assets and convert funds back into Japanese yen to repay loans). This could lead to:
For Hong Kong and Asian investors focused on Japanese markets, the impact of this policy shift is multifaceted:
Ending negative interest rates is only the first step in Japan’s monetary policy normalization. The market is now more focused on what comes next. This will become one of the key variables shaping the global financial landscape over the coming years.
The market generally believes the Bank of Japan will remain extremely cautious in its future actions and adopt a “wait-and-see” approach. Governor Kazuo Ueda’s comments have reinforced this view, emphasizing that more time is needed to assess the economic impact of the first rate hike. Most economists predict that the Bank of Japan may not implement a second rate hike until the second half of 2026 or early 2027, and even then, the increase would likely remain moderate (such as raising rates to 0.25%).
Future rate hike decisions will depend heavily on the following key data:
Facing Japan’s new monetary policy environment, investors should consider reassessing and adjusting their asset allocation strategies:

A: Not in the short term. Since the market had already priced in expectations ahead of time, and the Bank of Japan delivered dovish signals by emphasizing that it would maintain accommodative conditions, combined with the still-massive interest rate gap with the US, the Japanese yen currently lacks strong momentum for sharp appreciation in the short term and may even weaken further due to a “sell the news” effect. From a medium- to long-term perspective, only if Japan continues raising rates while the US begins cutting rates, thereby narrowing the interest rate differential, will the Japanese yen gain a substantial foundation for appreciation.
A: That depends on your investment strategy and risk tolerance. Japan’s stock market moving away from deflation and entering an environment of moderate inflation is generally positive for corporate earnings over the long term. Sectors such as financials and domestic consumption may directly benefit. However, investors should also remain cautious about the potential negative impact of future Japanese yen appreciation on export-oriented companies. A stock-picking strategy is recommended rather than blindly buying the entire market.
A: Rate hikes will directly push up mortgage rates and increase borrowing costs for homebuyers, potentially creating a cooling effect on property sales, especially among highly leveraged investors. However, economic recovery and wage growth may also boost rental market demand and rental prices, which could benefit long-term rental property investors. Overall, short-term volatility risks in the real estate market are increasing.
A: YCC (Yield Curve Control) is a policy tool introduced by the Bank of Japan in 2016 with the goal of controlling 10-year Japanese government bond yields around 0%. When market interest rates rose, the central bank would purchase unlimited amounts of government bonds to suppress yields. The abandonment of YCC was due to the growing side effects of artificially distorting market prices (interest rates) in an environment where inflation had returned. It not only damaged bond market liquidity, but also caused the central bank’s balance sheet to expand excessively. Ending YCC was a key step toward allowing interest rates to return to market-driven mechanisms.
A: The short-term impact is limited. Since the Japanese yen weakened instead of strengthening after the rate hike, current exchange rates for traveling and shopping in Japan remain highly favorable. However, in the long run, the broader direction of Japan’s monetary policy normalization is to allow the Japanese yen to return to its fair value, meaning the yen has appreciation potential in the future. Therefore, if you have long-term travel or spending plans related to Japan, you may consider exchanging Japanese yen gradually during periods when the yen remains relatively cheap.
In summary, the Bank of Japan’s rate hikes and the end of negative interest rates represent an important milestone in Japan’s monetary policy normalization journey, symbolizing the country’s effort to emerge from the “Lost Thirty Years”. Although short-term markets remain filled with uncertainty due to dovish guidance and persistent interest rate differentials, causing the Japanese yen to weaken instead of strengthen, the long-term implications suggest that Japan’s economy is gradually escaping deflationary pressures. This will create structural impacts on global capital flows and asset allocation.
