Mexico and Japan Fiscal Dilemmas Offer Lessons for Economic Policy, Digi Mart USA News: A new analysis published by Gaceta UDG, a publication of the Universidad de Guadalajara, examines fiscal measures taken by Japan and their implications for Mexico’s economic policy.

The debate over Mexico’s Economic Package usually focuses on the urgent need for fiscal consolidation. At first glance, Mexico’s gross general government debt, at 58.4% of GDP on average during 2020–2027, appears favorable compared with Japan’s 214.2% of GDP over the same period.
The authors argue, however, that a close reading of IMF data shows both countries face fiscal and monetary dilemmas with opposing characteristics, each carrying severe long-term costs for economic development.
According to IMF projections from October 2026, Japan is expected to fall from fourth place in 2026 to sixth place in 2027, surpassed by India and the United Kingdom. The authors describe Japan’s trajectory as a critical mirror for emerging economies.
They note that the prolonged stagnation is not solely demographic but is also linked to three decades of persistently expansionary monetary policy. Faced with high public debt and weak growth, the Bank of Japan kept benchmark rates ultra-low or negative.
Net interest payments in Japan averaged less than 0.4% of GDP during 2020–2027, according to the authors’ calculations based on IMF data. The authors attribute this low interest burden to low interest rates and the characteristics of Japan’s debt financing.
They also note that Japan is one of the world’s major net creditors, although that position reflects the economy as a whole rather than the government alone. Long-term structural costs, however, were considerable.
The authors argue that persistently low policy rates may have reduced financial pressure on some firms and helped keep inefficient productive units in operation, with possible effects on the reallocation of resources and the process of creative destruction. This coincided with prolonged deflation and weak economic activity.
Japan also gradually lost relative weight in the global economy, although the trend in its nominal GDP measured in dollars is also influenced by exchange-rate movements.
In the authors’ view, Japan’s experience suggests that a prolonged strategy of extremely low rates can ease fiscal pressure in the short term but can also create incentives that limit economic dynamism and the efficient reallocation of resources over the long run. At the opposite end of the macroeconomic spectrum is Mexico.
According to the authors’ calculations, Mexico devotes on average more than 5% of GDP to net interest payments during 2020–2027, a burden roughly fourteen times that of Japan as a share of GDP.
The authors describe this as the trap of the Mexican model: the rigidity of this commitment is not merely an ideological preference for austerity but a structural necessity. A persistent deterioration of the primary balance could increase risks to debt sustainability and generate pressure on credit ratings, the exchange rate, and capital flows.
This high debt-service cost reduces fiscal room for maneuver and limits resources available for strategic public investment in infrastructure, health, security, and education.
Against this backdrop, improving citizens’ welfare without significantly expanding public spending has become one of the main challenges of economic policy. The authors note that one response in recent years has been a sustained increase in the minimum wage, but its long-term sustainability depends on the evolution of labor productivity.
In an economy where more than 50% of employment is informal, wage increases not accompanied by sufficient productivity gains may pressure business costs, especially for small and medium-sized enterprises, and hinder the formalization of employment.
The authors conclude that Mexico cannot decree prosperity or sustain indefinitely the growth of real wages if the productive sector lacks the financial, technological, and productive capacity to support it. The Economic Package, they argue, should not be assessed solely by the simplistic metric of the nominal deficit or the debt ceiling.
Japan’s experience suggests that maintaining excessively loose financial conditions without structural reforms or sustained productivity improvements can contribute to prolonged economic stagnation.
The challenge for Mexico’s Economic Package and public policies, the authors state, is to design an environment in which fiscal consolidation coexists with real incentives for productive investment, technology adoption, and economic formalization. Only through a productive sector capable of generating greater added value and raising productivity, supported by private investment and effective public-private collaboration, the authors argue, will it be possible to service the cost of debt, sustain truly dignified wages, and avoid a prolonged path of low growth similar to Japan’s in recent decades.
