Grain prices spiked after Russia revived plans for grain export duties amid fears that its surging pace of shipments would deplete inventories.
Viktor
 Zubkov, the Russian deputy prime minister who in June voiced proposals 
for a levy, said on Tuesday that the government was considering reviving
 the plan to prevent its grain stocks falling below 15m-16m tonnes.
While
 Russia has seen a sharp revival in its grains production from last 
year's drought-affected levels of 61m tonnes - with Mr Zubkov pegging 
the harvest at 90m-92m tonnes and Prime Minister Vladimir Putin last 
week estimating the crop at 95m tonnes – keen prices have seen a surge 
in supplies leaving the country.
