On any given evening, the neon signs in Osaka’s Dotonbori neighborhood are unrelenting: ramen shops, pachinko parlors, and tourist traps all blaze brightly. The city never really felt as though it was subject to a monetary policy experiment. However, it was for eight years. Japan as a whole was. It took years for most people outside of financial circles to fully understand the Bank of Japan’s counterintuitive policy of charging commercial banks for keeping money in their vaults. That experiment was formally terminated on March 19, 2024, by a 7-2 vote at the BOJ’s March policy meeting. Japan was the last nation on the planet to stop charging negative interest rates. The ruling was subtle, well-crafted, and had significant ramifications.
Even at the time, making the case for negative interest rates was never simple. There was a certain mechanical logic to the basic idea that charging banks for holding reserves would compel them to lend money into the economy, boosting growth and rescuing Japan from its decades-long battle with deflation. The first significant central bank to attempt it was the European Central Bank in 2014. In 2016, Japan did the same, lowering its policy rate to -0.1%. After that, the policy simply remained in place. The BOJ maintained its position year after year despite international trade disputes, pandemics, and shocks to commodity prices, while all other major central banks either never went negative or recovered. The majority of economists watched Japan’s experiment with a mix of curiosity and uneasiness as it sat alone at the bottom of the rate table.

Wages played a major role in the decision to finally relocate. Before he could justify raising rates, BOJ Governor Kazuo Ueda had made it clear that he needed to see proof of sustainable wage growth, which was almost unprecedented for a central banker. Days before the March meeting, Rengo, Japan’s largest trade union federation, announced that ongoing wage negotiations had resulted in a provisional weighted average base pay increase of 3.7%. This was the signal he was waiting for. That number is significant because it exceeded the previous year’s gains, which had already been the steepest in thirty years. The BOJ had always believed that domestic demand and wage growth would have to reinforce one another. There was real evidence that the loop might be beginning to turn for the first time in a long time.
However, the decision was not unanimous, and the two votes cast in opposition during the policy meeting are not insignificant. Following the announcement, Rob Carnell, head of Asia Pacific research at ING, put it plainly: the BOJ had “taken a bit of a punt” on the assumption that significant wage increases across numerous firms would actually translate into growth in household spending. “At the moment, they don’t know that,” he replied. It’s worthwhile to sit with that genuine uncertainty. Knowing that the economy won’t send a clearer signal than this one, central banks raise rates based on their best assessment of the data rather than on certainty. After reviewing the wage data, Japan’s policymakers decided it was sufficient and took action. It will take months, if not longer, to determine whether the spending will follow.
This wasn’t merely a symbolic move, so it’s important to comprehend the new policy’s workings. Starting on March 21, the BOJ will use its short-term interest rate as its main tool, setting it at 0.1% on current account balances held by financial institutions. Additionally, it declared it would no longer buy exchange-traded funds and Japanese real estate investment trusts, and it eliminated yield curve control, a different, intricate mechanism it had used to cap longer-term interest rates near zero. It promised to reduce its purchases of corporate bonds and commercial paper, with the goal of completely ceasing that practice in about a year. These are not small changes. When combined, they offer a thorough unraveling of Japan’s monetary system following the crisis.
The market’s initial response was instructive and somewhat counterintuitive. Instead of strengthening in response to the news, the yen declined, reaching a four-month low against the US dollar and its lowest level against the euro since 2008. At first glance, this seems counterintuitive: a rate increase typically strengthens a currency. However, a large portion of the move had already been absorbed by the markets because it had been so well telegraphed and carefully signaled beforehand.
Perhaps the weakness of the yen showed how ingrained the carry trade had become in international finance. Japanese yen loans to foreign investors increased by $460 billion over the previous three years, reaching $1.8 trillion. For years, investors had been taking out cheap yen loans and using the money to invest in other, higher-yielding assets. Any significant strengthening of the yen could start to undo that trade, with uncertain consequences for bond and equity markets well outside of Japan.
Following the announcement, the three biggest banks in Japan—Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, and Mizuho Financial Group—quickly increased interest rates on regular yen deposits. This was the first concrete indication of change for average Japanese savers. For many years, having money in a Japanese bank account meant making very little money. In Japan, the saving-reward relationship that was so widely accepted elsewhere had simply stopped working. Even though it was a tentative return, it felt like something was changing on the ground as opposed to just at the level of policy declarations.
Rather than being merely a technical change, this pivot may signal the start of a true new chapter for Japan’s economy. Expectations of rising inflation often release pent-up consumer spending; when consumers anticipate price increases, they make purchases sooner rather than later, which can support investment and corporate profits. Analysts keeping an eye on Japanese consumer discretionary companies, banks, and industrials are cautiously optimistic.
The risks are still present: a significant sell-off in US Treasury bonds could be triggered by a sharp increase in the value of the yen, as Japanese investors who own substantial amounts of US debt may decide to repatriate funds if domestic returns become more alluring. Global markets are aware that this is a thread worth keeping a close eye on. It could be the end of Japan’s protracted experiment with negative rates. The effects of putting an end to it are just now starting to become apparent.
