Summary of Key Points
For the first time, the Japanese government and the central bank have reached a consensus that it is "necessary to raise interest rates in the near future." The next interest rate hike could occur at the central bank meeting on September 18th or October 29th-30th. Currently, the market believes there is a 74% probability of an interest rate increase in September. The reasons behind this include the depreciation of the yen, which has led to rising import prices (imported inflation), a sharp decline in government support rates (due to increasing living costs), and the United States' open stance towards Japan's tightening policies. However, there is still disagreement within the market regarding the timing of the hike (September versus December). The biggest risk is that the concentrated liquidation of yen carry trades could cause a shock to global markets.
Why Is Japan Urgently Seeking an Interest Rate Hike Now?
Simply put, the yen has depreciated too much, and both ordinary citizens and the government can no longer afford it:
1. Yen Depreciation = Rising Import Prices: The weaker the yen, the more expensive imported goods such as oil and food become, leading to increased domestic prices (this is known as "imported inflation"), which significantly raises the cost of living for people.
2. Government Support Rates Have Plummeted: The support rate for the Komiya Haruko cabinet has dropped to its lowest level since she took office, with dissatisfaction rising from 56% to 71%. The government must take action to regain public trust.
3. The U.S. Has Given Its Green Light: The U.S. Treasury Secretary previously stated that it is necessary for Japan to strengthen the yen, effectively giving the green light for an interest rate hike (previously, Japan was concerned about the impact of raising rates on U.S.-Japan relations, but now there are no such concerns).
4. Foreign Exchange Intervention Is Uneffective: Japan has spent 11.73 trillion yen on foreign exchange intervention (buying yen and selling dollars) without success in stabilizing the currency; this indicates that only an interest rate hike can narrow the interest rate gap between Japan and the U.S. (by increasing yen interest rates, people will be more inclined to hold yen), thereby stabilizing the exchange rate.
When Will the Interest Rate Hike Take Place: September or December?
The main disagreement in the market revolves around whether to act quickly:
- Those in Favor of a Hike in September/October: Citibank and Barclays believe that inflation pressures are too high, and since the U.S. supports this, an hike should be made soon. Strategists at Morningstar predict a hike in October, as the central bank has already signaled an acceleration in the pace.
- Those in Favor of a Hike in December: Mizuho Securities and the Daiichi Life Research Institute argue that there is a lack of key data (such as corporate semi-annual reports, which will be released in November) between September and October, and they fear that a hike could affect households with mortgages and small and medium-sized enterprises (higher interest rates would mean more loans to repay). December would be a safer time.
Current Situation: The market estimates a 74% probability of an interest rate hike in September, but December is still the mainstream prediction. After all, the Bank of Japan has been very cautious over the past 15 years, and a sudden acceleration could lead to problems.
What Will the Interest Rate Hike Do for the Yen?
Finally, Japan won't have to rely on "throwing money at the problem" to stabilize the currency:
Previously, Japan used its foreign exchange reserves to intervene in the market (buying yen and selling dollars), but this approach has become increasingly ineffective:
- High Intervention Costs: The amount of intervention at the end of July set a historical record, yet it did not stop the yen from depreciating.
- An Interest Rate Hike Is the Solution: The interest rate gap between Japan and the U.S. is the core issue behind the yen's depreciation. With higher U.S. interest rates, people exchange yen for dollars to earn interest. After a Japanese interest rate hike, yen interest rates will rise, narrowing the gap, making it more worthwhile to hold yen, which should help stabilize the currency.
Morningstar predicts that by the end of 2026, the dollar could trade in the range of 150-155 against the yen (currently around 147, indicating a gradual appreciation of the yen).
What Is the Biggest Risk for Global Markets?
The biggest risk is the potential "stampede" in yen carry trades:
Let's explain what carry trades are first:
Carry Trades: These involve borrowing yen at low interest rates (e.g., 1%) to buy high-interest-rate U.S. assets (such as U.S. government bonds, with interest rates of around 5%) to earn the interest difference. Such trades are particularly common right now.
Risk: If Japan raises interest rates faster than expected and the yen appreciates suddenly, traders involved in carry trades will quickly sell dollars to buy back yen and repay their loans. This could lead to a sharp drop in the dollar and a surge in the yen, potentially triggering a sell-off of other assets (such as stocks and bonds), similar to the market turmoil in August 2024 (similar to the "Truss moment" in the UK).
- Cautionary Views: Organizations like Morningstar and Russell Investments believe this risk cannot be ignored, especially since there are many short positions in the yen. A reversal could be very dramatic.
- Optimistic Views: JPMorgan Chase believes that the interest rate gap between Japan and the U.S. is still large enough for now, so carry trades will not be liquidated suddenly, and there's no need to worry too much.
Is the Bank of Japan Really Independent?
The Bank of Japan is legally independent, but the government can influence its decisions through various signals:
- In the Past: The Komiya government was concerned about the impact of interest rate hikes on economic recovery and prevented the central bank from raising rates quickly.
- Currently: Due to the sharp decline in support rates, the government is actively sending signals to the central bank, supporting Governor Haruo Kuroda's more hawkish stance (in favor of raising rates).
- U.S. Support: The U.S. is willing to coordinate intervention in the yen and also sees benefits in a Japanese interest rate hike (which could help stabilize global inflation), so the government's influence on the central bank has weakened, giving the central bank more courage to raise rates.
In summary, Japan's decision to raise interest rates is "forced by circumstances," but the timing and impact are still uncertain. Global markets are closely watching this development, as it represents a potential "black swan" event.
