Research<br>The Tradeoffs Facing Japan's Economy

By Wojciech Gryc &middot; August 10, 2026 &middot; 7 min read

This past week's US-Japan collaboration on shoring up the Japanese yen leads to the<br>question—what's wrong? Why is the Japanese yen getting so weak, and is there something<br>wrong with the Japanese economy?

Japan has one of the largest debt-to-GDP ratios and is particularly disadvantaged due to the Iran<br>War driving up oil and energy prices. At the same time, its technology industry has a lot to<br>offer, but not without tradeoffs. Here, we're exploring some of those tradeoffs: interest<br>rates versus debt, investing in the future while managing concerns about overspending, and<br>managing national ambition alongside consumer price concerns.

Japan's economic challenges

A full-blown overview of Japan's economy is beyond the scope of our writing. Instead,<br>we'll list some of the larger challenges and initiatives tied to Japan's economic<br>development before exploring the tradeoffs.

Japan has one of the largest debt-to-GDP burdens in the world, at over 200%. Prior to last<br>week's US-Japan currency intervention, its currency lost over 10% of its value this year. Prime<br>Minister Sanae Takaichi is working on a growth-oriented agenda, but facing challenges as inflation<br>hovers at 1.7% and peaked at 3.7% in May 2025[1].<br>Worse still, a 1.7% inflation rate hides the challenges faced by Japanese consumers: food prices<br>have increased 3.2%, with fish and seafood growing at 6.9% this past year[2]. While fuel and energy prices have been flat, this is only<br>because they are actively subsidized by the government.

Against the inflation backdrop, Prime Minister Takaichi's approval rating dropped from 69% in<br>June to 57% in July. Specific criticisms target her attempts at fighting cost-of-living price rises,<br>with 71% disapproving of her administration's strategy[3]. The challenges are partly out of Japan's control: global<br>energy prices have skyrocketed, leading to significant increases for energy imports.

This is the context that Japan's government finds itself in, and many of its options come with<br>painful pros and cons.

Tradeoff: raise interest rates to fight inflation, and hurt<br>consumers

Japan's official interest rate is set to 1%, which was reaffirmed in the July 30/31 Bank of<br>Japan meeting[4].

Higher interest rates should help reduce inflation[5]<br>and encourage more saving. More importantly, higher interest rates reduce the benefit of the carry<br>trade, where investors borrow in Japanese yen (paying the relatively low local interest rate),<br>sell the yen by converting it to other currencies, and then buying international assets. This<br>enables investors to benefit from low Japanese interest rates while arbitraging higher rates and<br>returns elsewhere. Since such investors sell yen, they drive the price of the yen down, which<br>increases costs of other imports, like energy and food.

While increasing interest rates is seen as the sensible central bank policy, there are issues with<br>this. First, higher interest rates also increase the cost of borrowing for<br>consumers—mortgages, car loans, and other products become more expensive, potentially<br>driving further dissatisfication with Takaichi's policies.

Secondly, higher interest rates lead to lower valuations for existing bonds, as yields need to<br>match what bond buyers get in the markets today. This can lead to losses on bonds already<br>purchased. Japan's four largest life insurers have lost about $96 billion in Q2 2026 based on<br>current rises in interest rates[6]. While consumers can<br>be forgiven for not shedding a tear for trillion-yen corporations, losses driven by interest rates<br>were why Silicon Valley Bank collapsed in 2023[7].<br>Raising rates slowly could be the lesser of two evils.

Tradeoff: increase consumer support, and increase<br>debt

The Takaichi administration is driving policies that help reduce day-to-day costs for consumers. It<br>is aiming to reduce tax on food from 8% to 1% as of April 2027[8], which will cost about $32 billion[9]. To ensure high oil prices don't translate to significant<br>consumer price increases, the government has been releasing oil from its reserves to cap gas<br>prices at &yen;170/liter, and further earmarked $19 billion to subsidize fuel costs[10].

All of the above drives increases in debt. Japan's current year government budget is at $780<br>billion, and $83 billion (10.7%) of the budget goes to paying interest on its current debt[11]. These costs are expected to rise about 50% over<br>the coming years[12]. When accounting for debt<br>servicing and debt rollovers, Japan's government is spending 25.6% of its budget to service<br>and manage its debts[11].
