Bank of Japan (BoJ) Governor Kazuo Ueda recently remarked that Japan's real interest rates are "clearly negative," a simple but powerful statement explaining the country's current monetary policy.
So, what exactly does this mean? It's about the difference between the 'sticker price' of interest and its real value. The BoJ's policy rate, the nominal rate, is around 0.75%. However, when you subtract the current inflation rate of about 1.8%, you get the real interest rate, which is approximately -1.05%. A negative real rate means that if you borrow money, the value of what you pay back is less than the value of what you borrowed, once inflation is accounted for. This is why Governor Ueda describes the BoJ's stance as still being 'accommodative' or stimulative, even after raising the nominal rate.
The primary goal of this policy is to encourage economic activity, particularly business investment. By keeping real borrowing costs low, the BoJ hopes to spur companies to invest in new equipment, technology, and facilities—what economists call capital expenditure (capex). Recent data supports this idea, with core machinery orders showing a significant jump. This suggests that the accommodative financial conditions are indeed translating into real-world investment, just as the BoJ intended.
This policy didn't appear overnight. It's the result of several key developments. First, the BoJ's rate hike to 0.75% in late 2025 was accompanied by messaging that the policy would remain easy. Second, strong wage growth, confirmed by the annual 'shuntō' negotiations where unions and companies agree on pay, has supported inflation, helping to keep the real rate negative. Third, temporary factors like government subsidies have recently pushed measured inflation down, making the real rate even more negative.
However, the BoJ is performing a delicate balancing act. The main constraint is the weak yen, with the USD/JPY exchange rate hovering near 160. This level is a sensitive point for policymakers, as it triggered massive government intervention to support the yen in 2024. A policy that is too accommodative could weaken the yen further, risking instability. This is why the BoJ emphasizes that its future actions will be data-dependent, allowing it to maintain flexibility while trying to support a fragile economic recovery.
- Real Interest Rate: The interest rate that has been adjusted to remove the effects of inflation. It is calculated as the nominal interest rate minus the inflation rate.
- Capex (Capital Expenditure): Funds used by a company to acquire, upgrade, and maintain physical assets such as property, plants, buildings, technology, or equipment.
- Shuntō: The Japanese term for the annual spring wage negotiations between labor unions and employers. Its outcome is a key indicator for wage growth and inflation trends.
