Mexico's fiscal response to the pandemic has been modest compared to its peers, reflecting the authorities' desire to not issue new debt for spending. This approach, however, resulted in a more severe recession in 2020 and a weaker economic recovery, notwithstanding spillovers from the United States. Balancing the need for stronger near-term fiscal support for the people and the recovery against medium-term discipline, this paper lays out an alternative strategy. We show that credibly announcing a pro-growth and inclusive medium-term fiscal reform upfront—including increased tax capacity, higher public investment and strengthened social safety nets—would open space for larger short-term support and close medium-term fiscal gaps. Model simulations suggest that this package would boost output, limit lasting economic damage from the pandemic, and put debt trajectory on a declining path in the medium term as tax reforms pay off and risk premia decline.
