“Minimal Tax-Cut Impact, Escalating Fiscal Risks”: Takaichi’s 1% Consumption Tax Gambit Could Deepen Bond and Currency Volatility

Food consumption tax cut to 1% weakens annual revenue base by $34.5 billion
Additional bond issuance and refinancing costs likely to rise to fill funding gap
Weak yen and rising import prices risk entrenching a fiscal-monetary vicious cycle

Japanese Prime Minister Sanae Takaichi is pursuing an extraordinary tax-cut plan that would lower the consumption tax rate on food to 1% for two years. The measure is intended to revive domestic demand, which has been weakened by elevated inflation and falling real wages. Yet, considering the annual revenue shortfall of approximately $34.5 billion and the limited boost to consumption, the policy’s fiscal efficiency appears markedly low. Moreover, with the expected rebound in consumption unlikely to offset the fiscal gap, government debt equivalent to roughly twice gross domestic product (GDP) and government bond yields at three-decade highs could swiftly turn the cost of the tax cut into higher interest expenses and a larger fiscal-risk premium. That burden is likely to intensify yen depreciation and push import prices higher again, while making it more difficult for the Bank of Japan’s rate hikes to encourage overseas income repatriation and unwind yen carry trades—potentially undermining the yen’s status as a safe-haven currency.

Extraordinary Tax Cut to Break Through High Inflation and Consumption Stagnation

According to the Nikkei on July 30, Prime Minister Takaichi, who had pledged a temporary reduction in the consumption tax rate, is expected to formally announce this week a plan to lower the rate to 1% from next April. At a press conference held at the Prime Minister’s Office in Tokyo on July 27, Takaichi said that, following bipartisan discussions on cutting the food consumption tax, she intended to swiftly submit related legislation, adding that she wanted the public to “feel the effect of easing the burden as quickly as possible.”

The original pledge of the Takaichi administration was to cut the current 8% food consumption tax rate to 0% for two years. However, technical constraints emerged, including projections that eliminating the food consumption tax temporarily could require more than a year simply to replace checkout systems at supermarkets and other retailers. As a result, an alternative proposal gained traction: reduce the food consumption tax to 1%, rather than 0%, and use income-linked assistance to effectively eliminate the remaining tax burden.

Under the plan, the food consumption tax would be temporarily lowered to 1% for two years beginning next April, substantially reducing consumers’ perceived inflation burden. With consumption having weakened amid sharp food-price increases and declining real wages, Takaichi’s objective is to revive domestic demand through a tax cut whose effects households can feel immediately.

The Japanese government characterizes the 1% consumption tax rate as a temporary “bridge” measure until a new benefits, or cash-transfer, system for low- and middle-income households is fully introduced from fiscal 2029. Under the working-level proposal, the reduced 1% rate would apply temporarily for two years beginning in April 2027, while advance benefits equivalent to the remaining 1% would be provided to produce an effective “0% consumption tax effect.”

A Fiscal Gamble Under the Banner of Livelihood Support

However, fiscal-soundness concerns could intensify if bond issuance rises to compensate for tax-revenue losses. Japan’s consumption tax is a core revenue source supporting social-security spending associated with population aging. Food-tax cuts may quickly reduce households’ perceived burden, but their fiscal efficiency is constrained because benefits are distributed in proportion to consumption regardless of income level. Critics also argue that the policy multiplier may be lower than if the same resources were directed toward cash assistance for low-income households and energy-cost relief.

The tax cut’s economic-stimulus effect relative to its cost is also notably weak. Daiwa Institute of Research, the research arm of Daiwa Securities, estimated that cutting the food consumption tax to 0% would reduce the annual burden on each household by an average of $607, while increasing private consumption by $3.45 billion and GDP by $2.07 billion. Even after relinquishing $33.1 billion in annual tax revenue, the GDP increase would amount to only around 6% of fiscal expenditure. Food is an essential good, meaning that lower prices do not sharply increase purchase volumes; consequently, most of the tax cut is absorbed in offsetting existing expenditure.

Consumer Benefits Diluted by Rising Costs

The price reductions consumers ultimately experience will also not necessarily match the statutory tax-rate cut. Daiwa Institute of Research calculated that a 1% tax rate would mechanically lower the core consumer price index (CPI) by around 1.3 percentage points. In overseas cases of value-added-tax reductions, the full value of tax cuts was not passed through to retail prices. Assuming a pass-through rate of 70%, the actual decline would shrink to around 0.9 percentage points. Once the cost of overhauling payment systems, labor costs and higher raw-material prices are reflected in product prices, the change on the price tags consumers see could become even more negligible.

The two-year time limit also constrains the policy’s ability to stimulate consumption. Households are unlikely to regard a temporary increase in disposable income as a lasting improvement in income, and may save much of it or use it to cover existing shortfalls in living expenses. When the tax rate is restored to 8% in 2029, food prices would jump abruptly and consumption could weaken again. The political timetable—under which a decision on whether to restore the rate must be made ahead of the summer 2028 House of Councillors election—could further intensify pressure to extend the tax cut. The annual revenue loss of approximately $34.5 billion, initially framed as a temporary measure, also faces a growing risk of becoming a permanent expenditure.

Table 2. Japan’s Government Debt Status

Tax Cuts Fuel a Vicious Cycle of Rising Interest Costs

Japan already has a government-debt-to-GDP ratio well above 200%. According to Japan’s Ministry of Finance, outstanding government bonds stood at approximately $8.33 trillion at the end of fiscal 2025, while government debt—including borrowings and government short-term securities—totaled approximately $9.27 trillion. Under the fiscal 2026 budget, combined central and local government long-term debt stood at approximately $9.27 trillion, equivalent to 194% of GDP. As higher interest rates accumulate during the refinancing of existing debt, a weakened revenue base will amplify interest costs over an extended period.

The bond market is already signaling concern over the Takaichi administration’s expansionary fiscal stance. Japan’s 10-year government bond yield surged to 2.9% on July 9, its highest level in three decades, and has recently remained near 3%. The Bank of Japan’s share of outstanding medium- and long-term government bonds stood at 49% at the end of 2025. As quantitative tightening proceeds through gradual reductions in monthly purchases, the volume private investors must absorb is increasing. Should tax revenue decline further because of tax cuts, the fiscal-risk premium demanded by the market will rise accordingly.

Additional Pressure on an Already Weak Yen

This is also likely to place further downward pressure on the already weak yen. The Bank of Japan raised its policy rate from 0.75% to 1% last month and stated that it would continue raising rates depending on economic and inflation conditions. In a Reuters survey of 87 economists this month, 86% expected the policy rate to rise to 1.25% by year-end. With the U.S. policy rate remaining at 3.50%–3.75% and Japan’s real interest rate still negative, gradual tightening in 0.25-percentage-point increments is insufficient to overturn the profit structure of yen-funded trades.

In practice, the yen weakened to the 163-per-dollar range even after the rate hike, reaching its lowest level since 1986. In its July foreign-exchange report, the U.S. Treasury Department assessed that the yen’s value against the dollar and its real effective value had each fallen by 51% from the end of 2011 through April this year, with weakness persisting despite a narrowing U.S.-Japan interest-rate gap. The failure of rising government bond yields to translate into currency appreciation indicates that markets are viewing part of the increase in yields not as a product of successful monetary-policy normalization, but as compensation for expanding fiscal risks.

Japan’s vast external asset base is also affecting the exchange rate in a way that differs from the past. Japan recorded a current-account surplus of approximately $238.1 billion in fiscal 2025, of which the primary-income surplus generated by overseas investment accounted for approximately $291.6 billion. Net external assets reached a record approximately $3.87 trillion at the end of 2025. Companies and financial institutions are increasingly reinvesting profits earned overseas locally rather than converting them into yen and bringing them home, weakening the channel through which large accounting surpluses translate into yen buying.

The Yen’s Safe-Haven Status Also Under Strain

The yen’s status faces the same pressure. If yen weakness becomes prolonged, the longstanding equation of “yen equals safe-haven asset” in the Japanese economy could enter a period of reassessment. Since the 1990s, the yen has functioned as a classic refuge currency, strengthening whenever global financial markets were shaken as low-interest yen borrowing positions were unwound and expectations of Japanese investors repatriating overseas assets grew.

However, even as net external assets expand, the growing entrenchment of local reinvestment of overseas earnings, coupled with fiscal expansion and government-bond-market volatility eroding confidence in the currency, is weakening the rationale for buying yen in times of crisis.

In particular, yen depreciation inflates the yen-denominated earnings of major exporters while raising the cost of imported raw materials, energy and food, spreading what is often described as a “bad weak yen” that erodes real income. When wage growth fails to keep pace with rising import prices, household purchasing power weakens and the government again faces demands for broader tax cuts and subsidies. If the mutually reinforcing cycle of expanded tax cuts and bond issuance, yen weakness and rising import prices becomes entrenched, Japan’s longstanding policy formula of using a weaker currency as a buffer for growth may no longer function.
