CBOT wheat rallied in the week to May 22 after a forecast cut Russia's 2020 grain crop by 5 million tonnes to 120 million tonnes. A weaker rouble also made Russian wheat dearer and speculation grew that Russia would extend export quotas.
Dry conditions in southern Russia and Ukraine were noted but largely shrugged off.
A smaller Russian crop and possible export quota extensions tighten Black Sea wheat supply, supporting global wheat prices. Feed buyers may face higher wheat costs as a substitute in rations.
