This renewed interest in keeping public stocks was furthered by the realisation that price spikes tend to coincide with low stock-to-use ratios (Wright, 2012). Even though international crop prices have mostly fallen back since 2011 and most export restrictive measures that partly caused the crisis are no longer in use, many developing countries keep building public stocks. This was for example the case with the intervention stocks that were created under the Common Agricultural Policy in the European Union (EU) during the 1980s-1990s.
