Abstract

The 2025–2026 biennium has reignited global inflation alarms, driven by a fresh energy supply shock in the Middle East and the expansion of protectionist trade policies. While the world's largest economies, such as the United States and the Eurozone, grapple with prolonged high interest rates and stagflation risks, Latin America displays starkly contrasting environments. Brazil is tightening its monetary policy to curb currency devaluation and rising oil costs, Paraguay seeks to sustain its historical regional stability, and Argentina has stunned global markets with a drastic slowdown in prices following aggressive fiscal reforms. This analysis demonstrates that contemporary inflation has cemented itself as a structural and geopolitical phenomenon, demanding intense resilience from global supply chains. By Marcelo Salamon

Introduction
Global Outlook: Inflation is Not Over

Just as the world’s major economies were beginning to breathe a sigh of relief after finally moving past pandemic-era supply bottlenecks, the macroeconomic landscape delivered a harsh reality check: global inflation has not been fully tamed. The optimism that marked the turn of the decade evaporated in the face of a convergence of new shocks that have pushed global price indices toward the 4% mark.

According to projections and warnings from the International Monetary Fund (IMF), today's inflationary dynamics have ceased to be a mere reflection of temporary excess demand. Instead, they have become a direct byproduct of energy and geopolitical volatility. The world now faces an environment where price instability threatens to become entrenched if the core structural knots of global supply remain strained.

The Great Catalyst
Oil Above $100: How the Conflict in Iran Changes Everything

The primary engine behind this economic reversal was the outbreak and escalation of the conflict involving Iran. Geopolitical instability in the Middle East quickly translated into panic across commodity markets, driving the price of a barrel of Brent crude oil past the psychological barrier of $100.

The epicenter of this logistical and energy collapse is the Strait of Hormuz, a vital artery through which roughly one-fifth (1/5) of the world's oil traffic flows. The threat and subsequent partial blockade of this route choked the commodity's flow, triggering a devastating domino effect. The impact was felt directly and immediately at the gas pump, drastically driving up freight transportation costs, the industrial manufacturing of petroleum derivatives, and the price of nitrogen-based fertilizers—consequently putting immense pressure on the global food supply chain.

Territorial Dynamics and Impacts
Double Pressure and the Threat of Western Stagflation

On a global scale, economic superpowers are dealing with pressures coming from distinct yet equally severe fronts. In the United States, the Consumer Price Index (CPI) reached 4.2% in May, marking its highest level since 2023. This reality stems from a double-whammy: the implementation of protectionist trade tariffs that raised the cost of imported raw materials and consumer goods, coupled with an energy shock that caused domestic gasoline prices to spike by more than 40%. In response, the Federal Reserve has signaled that it will keep interest rates restrictive for much longer than anticipated, with Wall Street ruling out any meaningful rate cuts before 2027.

Across the Atlantic, the Eurozone is haunted by the ghost of stagflation—economic stagnation combined with high inflation. After a period of painful convergence where prices seemed to be heading toward the 2% target, the European market was struck by a new supply shock. As tensions mounted, projected natural gas prices skyrocketed by an astonishing 70% as strategic reserves rapidly depleted. The European Central Bank (ECB) forecasts highly volatile inflation fluctuating between 2.8% and 4.4%, forcing the European Union to shoulder a monumental €27 billion in extra costs for alternative fossil fuels.

Asymmetric Vulnerabilities and the Ripples in Latin America

This shockwave is propagating even more severely through peripheral and emerging economies. In Eastern Europe—most notably in Poland, Hungary, and Romania—a heavy reliance on energy imports combined with a narrower margin of maneuver for local central banks has caused core inflation to consistently outpace the Eurozone average.

In Latin America, the effects are manifesting in diverse ways. Brazil, which had closed the previous period within its official target ceiling (4.26%), reversed its downward trend. Projections now show the IPCA (the local consumer price index) pushing past 4.8%, heavily pressured by rising oil prices and a sharp depreciation of the Brazilian real against the US dollar. To prevent an unanchoring of inflation expectations, the Central Bank of Brazil has held its benchmark interest rate (Selic) above 13%—the highest real interest rate the country has seen in nearly two decades—adding significant volatility to the macroeconomic and political climate.

In stark contrast to this tightening cycle, the region also features intriguing, divergent dynamics. Paraguay has consolidated its status as a haven of relative stability, reaping the rewards of historically disciplined monetary policy and massive domestic hydroelectric power generation, though it remains vulnerable to the rising costs of imported manufactured goods.

Meanwhile, Argentina has emerged as the global market's biggest economic turnaround surprise. The nation, which suffered under a suffocating monthly inflation rate of 25.5% back in December 2023, managed to close the recent period with a consolidated annual rate of 21.5%—its lowest since 2017. This dramatic plunge in prices was the result of a harsh fiscal shock therapy program that completely erased the budget deficit and dragged the poverty rate down from a peak of 52.9% to the 31% range. Concurrently, GDP staged a recovery, growing by 5,2% in the first quarter, charting a clear course toward zero inflation.

Factor Analysis
Geopolitics: War as a Structural Inflationary Engine

The international arena makes it clear that contemporary inflation is not a purely monetarist phenomenon; it is a direct reflection of geopolitics acting as a structural engine. The persistence of the war in Ukraine, which continues to disrupt European gas supplies, combined with the new flashpoint in Iran, has fundamentally reshuffled international supply chains and logistical networks. The practical result is a stark divide in the global balance of payments, exposing a deep rift in economic resilience between strictly commodity-exporting nations and those heavily dependent on resource imports.

Protectionism: Tariffs and Imported Inflation

The resurgence and consolidation of aggressive protectionist policies have added fuel to the global price fire. The trade tariffs levied by the US administration have functioned as a two-way mechanism for imported inflation. Analysis by Goldman Sachs estimates that these trade barriers alone added over 0,5 percentage points (p.p.) to US domestic inflation throughout 2025. However, the collateral damage transcended American borders; the imposition of tariffs forced an abrupt reconfiguration of global supply chains, inflating operational costs and squeezing profit margins for trading partners across Asia, Europe, and Latin America.

Monetary Policy: High Interest Rates and the Cost of the Cure

To combat an inflation crisis rooted primarily in global supply shocks, central banks worldwide have resorted to the traditional cure: prolonged monetary tightening. This remedy, however, carries a steep economic price tag and leaves monetary authorities trapped between a rock and a hard place. On one side stands the sword of persistent inflation; on the other, the wall of a sharp, policy-induced economic slowdown brought on by choked credit lines. In light of these macroeconomic strains, the OECD revised its average inflation forecast for G20 advanced economies to 4%, signaling that a return to normalcy is still a long way off.

Conclusion

The current inflationary balance sheet reveals a deeply fragmented and uneven global map. Within this shifting balance of power, Argentina stands out as a surprising success story of inflation control driven by deep fiscal overhauls, while economic powerhouses like the United States and Western Europe remain under intense recessionary and currency pressures. Brazil, meanwhile, finds itself in a permanent state of high alert, forced to shield its domestic economy from severe external shocks.

Looking ahead, while mathematical models suggest global inflation could cool to the 2.6% range if conflicts in the Middle East and Eastern Europe subside, market optimism has been deeply shaken. The overarching lesson is that the road back to price stability has been permanently adjusted upward, requiring immense economic resilience, extended periods of high interest rates, and a complete re-engineering of global geopolitics.
