International food commodity prices have experienced a series of shocks over the past decade. The prices of rice, maize, and wheat spiked in 2007-08 as a result of supply shocks, demand for biofuels, and export trade restrictions. Commodity prices increased again in 2010-11. And most recently, global supply chain disruptions in the aftermath of the COVID-19 pandemic and Russia’s invasion of Ukraine sent international food and fertilizer prices soaring, though they have moderated somewhat after peaking in mid-2022.

Since peaking in April 2022, global agricultural food commodity prices have declined by almost 25% as of October 2023, according to the UN Food and Agriculture Organization’s (FAO) food price index (Figure 1). Contributing to the decrease were strong harvests in large food producing countries, steep declines in shipping costs, and more affordable energy and fertilizer prices (Figure 2).

Since early 2020, Guatemala has faced a multitude of food security shocks: from the outbreak of the COVID-19 pandemic and resulting restrictions on movement and disruptions to agricultural trade to widespread flooding following several major tropical storms to skyrocketing staple food prices. A new article in World Development examines the immediate and longer term impact of these shocks on households’ incomes, diets, food security, and migration decisions, particularly in rural areas.

With one in six people around the world almost entirely dependent on international trade to meet their food needs, agricultural trade can clearly play a pivotal role in both addressing and exacerbating food security challenges. While progress has been made to bring attention to food security needs in trade negotiations in recent years, harmful policies like temporary food export restrictions are still a common reaction to price spikes, market disruptions, and production shortfalls – shocks that are likely to become increasingly frequent due to climate change and ongoing conflicts.
