Emerging Markets: War, Oil & Rate Hikes Fuel Losses

Emerging Market Strain Deepens as Oil Prices and Rate Hike Fears Converge

Emerging market assets are facing their longest losing streak in nearly a year, fueled by escalating geopolitical tensions in the Middle East and growing expectations of interest rate hikes in the United States. The confluence of rising oil prices – surpassing $112 a barrel on Friday, March 22, 2026 – and the potential for tighter monetary policy is creating a challenging environment for developing economies, impacting currencies, stocks, and broader economic stability.

The downturn is particularly concerning given the recent surge in oil prices, directly linked to heightened anxieties surrounding potential US military intervention in Iran. CBS News reporting on “heavy” preparations for ground troops reportedly triggered the latest spike, prompting a risk-off sentiment across global markets. Even former President Trump weighed in, stating he doesn’t want a ceasefire, adding to the uncertainty. This situation is not simply about inflation; analysts warn of broader pressures on external balances, currencies, and capital flows within emerging markets, as highlighted by Reuters.

A gauge tracking emerging market currencies has fallen to its lowest level of 2026, declining 0.2% on Friday, March 20th. Simultaneously, an index of emerging market stocks experienced a 1% drop on the same day. These declines represent a third consecutive weekly loss, a pattern not seen since April 2025, when then-President Trump’s tariff policies rattled global markets. US Treasuries have also reacted negatively, with bond traders now pricing in a 50% probability of an interest rate hike by October, driven by concerns that a prolonged conflict in the Middle East will exacerbate global inflationary pressures.

The situation is particularly acute for Latin American economies. LatinFinance reports that the Iran war is stoking inflation fears across the region. J.P. Morgan Private Bank notes that Latin America possesses a “policy edge” – a combination of relatively high real interest rates and fiscal prudence – that may help it navigate the current cycle better than other emerging markets. However, even with this advantage, the region is not immune to the broader global headwinds. Finimize highlights that Latin American markets have already begun to slide as the oil shock rattles rate outlooks.

Brendan McKenna, an emerging-market strategist at Wells Fargo in New York, emphasizes that “markets are pricing more Fed hikes for this year.” This expectation of tighter US monetary policy further complicates matters for emerging markets, potentially leading to capital outflows as investors seek higher returns in the US. The shift in sentiment towards the US dollar, which advanced 0.5% last week, underscores this trend.

The current environment presents a complex challenge for policymakers in emerging markets. While higher oil prices may benefit some commodity-exporting nations, the overall impact is likely to be negative, particularly for countries heavily reliant on imports. The combination of rising inflation, potential capital flight, and the prospect of higher borrowing costs creates a precarious situation. Investors will be closely monitoring developments in the Middle East, as well as the Federal Reserve’s policy decisions, in the coming weeks and months. The trajectory of oil prices will be a key indicator, and any further escalation of geopolitical tensions could exacerbate the existing pressures on emerging markets.

Looking ahead, the persistence of higher crude prices – and the potential for further increases – will be a critical factor. As Morgan Stanley points out, rising defense outlays could widen deficits and push long-term Treasury yields higher, adding to the economic strain. The 2026 midterm elections in the US may even hinge on how long elevated oil prices persist, adding a political dimension to the economic concerns.
