The escalating conflict between Iran, Israel, and the United States has triggered a measurable spike in global inflation, with energy and food prices rising sharply and disproportionately impacting import-dependent economies like the Dominican Republic and the United States, where core inflation accelerated to 3.8% in March 2026, up from 3.2% in February, according to the U.S. Bureau of Labor Statistics.
The Bottom Line
- Global oil prices surged 22% in the first three weeks of April 2026, directly contributing to a 0.6 percentage point increase in U.S. Consumer price inflation.
- The Dominican Republic’s inflation rate reached 5.1% YoY in March, its highest level since 2022, driven by 18% increases in imported wheat and diesel costs.
- Major retailers including Walmart (NYSE: WMT) and Grupo Éxito (BVC: ÉXITO) have begun revising Q2 2026 profit guidance downward due to persistent input cost pressures.
The conflict, which intensified following Iranian missile strikes on U.S. Bases in Iraq on April 5 and subsequent Israeli retaliatory strikes on Iranian nuclear sites, has disrupted critical shipping lanes in the Strait of Hormuz and Suez Canal corridor. Global freight rates for crude oil tankers have climbed to $82 per barrel equivalent, the highest level since October 2023, according to Clarksons Research. This logistical strain is amplifying inflationary pressures not seen since the post-pandemic supply chain shocks of 2021–2022.
In the United States, the inflation surge is complicating the Federal Reserve’s monetary policy calculus. Despite two consecutive quarters of GDP growth averaging 1.9%, the core PCE price index—the Fed’s preferred inflation gauge—rose to 2.8% in February, exceeding the 2.5% threshold that would typically warrant caution on rate cuts. “We are not seeing the disinflationary trend we hoped for,” said Michelle Bowman, Federal Reserve Governor, in a speech to the Chicago Council on Global Affairs on April 12. “Geopolitical risk premiums are now embedded in energy and food markets, and that changes the math.”
“The Middle East conflict is acting as a persistent cost-push shock, not a transient blip. Companies with pricing power can pass through some costs, but margins are being squeezed across the board, especially in consumer staples and logistics.”

The impact is particularly acute in the Dominican Republic, where over 70% of cereal imports and 90% of diesel supply originate from regions affected by shipping delays or risk premiums. According to the Central Bank of the Dominican Republic, food inflation contributed 2.1 percentage points to the national CPI in March, while transportation added another 1.5 points. The government has extended fuel subsidies through June 2026 at an estimated monthly cost of $42 million, widening the fiscal deficit to 3.4% of GDP in Q1.
Corporate earnings are beginning to reflect the strain. Procter & Gamble (NYSE: PG) reported a 40 basis point YoY decline in gross margin during its Q1 2026 earnings call, citing “unfavorable commodity and freight impacts,” while Coca-Cola (NYSE: KO) noted a 3.5% increase in cost of goods sold across its Latin America division, driven by sugar and PET resin prices. In contrast, defense contractors such as Raytheon Technologies (NYSE: RTX) and Lockheed Martin (NYSE: LMT) saw order backlogs grow by 12% and 9%, respectively, in Q1, though analysts caution that these gains are offset by long-term supply chain volatility.

Market reactions have been uneven but discernible. The S&P 500 Consumer Staples Select Sector Index (^IXY) declined 4.1% over the past month, while the Energy Select Sector Index (^IXE) gained 6.8%, reflecting divergent sectoral impacts. Meanwhile, the MSCI Emerging Markets Index fell 2.9%, with Latin American equities underperforming due to currency depreciation and external vulnerability—the Dominican peso weakened 3.2% against the dollar in March, according to Bloomberg FX data.
Looking ahead, economists warn that sustained conflict could entrench inflation expectations. A survey of 50 global fund managers conducted by JPMorgan Chase in early April showed that 68% now expect U.S. Inflation to remain above 3% through the end of 2026, up from 41% in January. “The risk is not just higher prices today,” said Mohamed El-Erian, President of Queens’ College, Cambridge, and former chief economic adviser at Allianz. “It’s that businesses and households commence to behave as if high inflation is permanent—wage demands rise, contracts embed escalators, and central banks lose credibility.”
“We are entering a phase where geopolitical risk is no longer a footnote in economic models—it’s a primary driver. Ignoring it means mispricing assets and misunderstanding monetary policy transmission.”

For businesses, the imperative is clear: build scenario-based contingency plans that assume prolonged disruption in key trade corridors. Companies with diversified sourcing, domestic production capacity, or inflation-linked contracts are better positioned to absorb shocks. For policymakers, the challenge lies in avoiding premature monetary easing that could second-round inflate prices, while maintaining sufficient liquidity to prevent credit crunches in vulnerable economies.
As of the close of trading on Friday, April 18, 2026, the 10-year U.S. Treasury yield stood at 4.35%, up 28 basis points from the month’s low, signaling that markets are pricing in persistent inflation and a higher-for-longer interest rate outlook. The next inflection point will come with the release of April CPI data on May 14—if the trend continues, the Federal Reserve may delay its first rate cut until September.
