S&P Global: Only Severe El Niño and Costly Policy Responses Would Threaten Sovereign Ratings

Why El Niño Alone Won't Trigger Sovereign Rating Downgrades, According to S&P Global

S&P Global Ratings does not expect the El Niño weather phenomenon to trigger a wave of sovereign credit downgrades by itself, according to a senior analyst at the agency. Joydeep Mukherjee, lead sovereign analyst for Latin America, said in an interview that only a much more severe El Niño than currently anticipated, combined with costly government policy responses, would put rating actions on the table.

The timing and scale of the economic disruption matter, he explained, but the real deciding factor will be how policymakers handle the fallout. Even if a drought or flood temporarily disrupts activity, the economy should recover within six to twelve months, and credit ratings can typically absorb such short-lived shocks.

Mukherjee stressed that the critical variable is the fiscal response. If governments limit themselves to targeted support for affected households, the impact on public finances is manageable. However, broad-based measures—such as imposing caps on electricity or fuel prices—could create a parallel fiscal problem that compounds the natural disaster disruption.

Policy Decisions, Not Just Weather, Will Determine the Fiscal Toll on Sovereign Ratings

The Fiscal Trap of Price Controls

Mukherjee drew a sharp distinction between compensating the victims of a weather shock and interfering with market prices. Temporary cash transfers to families or businesses hit by floods or drought are unlikely to strain a sovereign’s credit profile. But when governments reach for economy-wide price controls, they end up shouldering costs that can widen deficits and push up debt. That, he warned, is what transforms a natural calamity into a credit rating concern.

Flexible Exchange Rates as a Shock Absorber

Countries that allow their currencies to float, such as Colombia and Peru, are better positioned to absorb weather-related economic shocks, Mukherjee noted. A flexible exchange rate helps restore competitiveness after a disruption without requiring painful domestic adjustments. Both countries could face significant economic impacts from El Niño, but their monetary frameworks give them more room to navigate the aftermath.

Ecuador’s Dollarized Vulnerability

The picture is different for economies that do not issue their own currency, like dollarized Ecuador. With fewer policy tools at its disposal, Ecuador may struggle to maintain competitiveness after a severe weather shock. Without a floating exchange rate to absorb the blow, the adjustment has to happen through domestic prices and wages, which can be slower and more painful. That structural rigidity makes Ecuador comparatively more exposed to rating pressure if El Niño proves particularly destructive.

How Governments Can Shield Their Ratings from El Niño's Economic Fallout

• For policymakers in vulnerable nations: Prioritize targeted cash transfers over economy-wide subsidies or price caps. A narrow fiscal response keeps deficits contained and reduces the risk of a negative rating action.
• For investors in sovereign debt: Monitor the fiscal response in El Niño-affected countries closely. Any announcement of fuel or electricity price controls should be treated as a red flag for potential credit deterioration.
• For Colombia and Peru: Their flexible exchange-rate regimes remain a credit strength. Even if growth slows temporarily due to weather disruptions, the rating impact is likely to be muted barring a severe policy misstep.
• For Ecuador: The absence of an independent monetary policy is a clear vulnerability. If a powerful El Niño materializes, the government may face a tougher trade-off between fiscal sustainability and economic support, warranting closer rating scrutiny.
