Food insecurity was top-of-mind throughout 2022 as the fallout from the conflict in Ukraine effected crop production and shipments. Diplomacy helped as the agreement of the Black Sea Grain Initiative restarted exports from Ukraine.
International organizations such as the World Bank, IMF, the WTO and others heightened surveillance of export controls on food and called for governmental restraint. Political appeals notwithstanding, the «Global Trade Alert» (GTA) recorded the implementation of 180 new export curbs in agricultural products last year, but 233 steps were taken to liberalize imports.
“What is at stake if the Black Sea Grain Initiative is not renewed in mid-March? What if Moscow weaponizes wheat exports during 2023?”
What about 2023? There is no end in sight to the armed conflict in Ukraine. Using reputable, December 2022 forecasts for wheat harvests during the 2022/23 season, this column presents evidence on the extent of Russia’s leverage of the world wheat market and its incentives to weaponize wheat.
The Russian government has three means to weaponize wheat exports:
Identifying possible motives for weaponization isn’t hard either. These include:
The extent to which Russian weaponization of wheat disrupts world markets and food security will depend on factors beyond Russia’s control, including the size of the global wheat harvest. The fact that wheat prices did not spiral out of control last year may be more down to good luck than good policy. Glauber et al. (2022) point out that Argentina and Brazil were able to expand their wheat exports by 6.6 million tons during the first half of 2022. Luck may be running out according to the well-regarded forecasts by the U.S. Department of Agriculture (2022 a,b). In its December 2022 update, the USDA foresees:
To put these forecasts in context, recall that prior to the conflict in 2020/21, Russia accounted for 19.2 percent of world wheat exports. Our simulations (Evenett & Muendler, 2023) predict that, in the absence of any weaponization of wheat trade, Russia would supply 22.8 percent of world wheat exports this year. Similarly, the U.S. Department of Agriculture (2022b) forecasts a 20.4 percent share. In contrast, the nations sanctioning Russia are expected to see their net production rise by only 0.9 percent of the world total. If Russia keeps its additional wheat production off world markets in 2023, Western wheat cannot easily replace it.
To make matters concrete, we considered scenarios where Russia blocks different percentages of Ukrainian wheat exports and where Russia decides to cut its own wheat exports by up to half. Our simulations show how much leverage the Russian Federation could have on world wheat prices and what threat Moscow poses to food security, principally in developing countries.
If the Kremlin withholds a quarter of Russia’s wheat exports, for example, it takes 10.8 million tons of wheat off the world market. Preventing all Ukrainian wheat shipments in the Black Sea, in contrast, only leads to small increases in Russian exports while larger shipments from other suppliers result in little change in total wheat supplies to the world market (Evenett & Muendler, 2023). Russia’s diplomatic niceties with respect to Black Sea transportation should, therefore, not be mistaken for good intentions towards the wheat market overall.
We also studied potential export tax regimes to assess the Kremlin’s incentives to manipulate world wheat markets. For instance, a Russian export tax regime that cuts one-quarter of Russia’s wheat exports generates for the Kremlin tax revenues equivalent to almost a third of the Russian wheat industry’s value added. Naturally, the economy-wide cost to Russia of the resulting market distortions is large, and amount to more than one-third of wheat value added. But in a war economy this loss may matter little in comparison to the Kremlin’s prospective use of any additional export tax revenues.
Here are key policy-relevant findings from our simulations (Evenett & Muendler, 2023):
“Bangladesh and Nigeria now face above-median wheat price increases of around 14 and 11 percent, while the Kremlin collects 55.6 percent of the Russian wheat industry’s value added in tax revenues.”
As Moscow scrambles to finance its military campaign in Ukraine, the temptation to weaponize wheat exports will grow. A larger harvest next year strengthens Russia’s leverage over world wheat markets. Russia’s influence on world wheat prices will be greater if it hikes export taxes as compared to refusing to extend the Black Sea Grain Initiative. Several developing countries with large populations are at risk should Moscow weaponize exports – and contingent financing to help could be lined up now. Russian wheat growers will also be victims of weaponization, diminishing their incentive to plant in future seasons.
“Conceivably, Russia could stockpile plenty of wheat and then engage in ‘wheat diplomacy’ with countries that are desperate to feed their populations.”
Foreign governments and international organisations should monitor not only Russian export tax changes but also Moscow’s state purchases of wheat from Russian farmers. The Black Sea deal is important but, as far as global food insecurity is concerned, it isn’t the only game in town.
