Could the selling which has depressed arabica coffee and raw sugar futures to the lowest since 2010 be past its worst?
There is hope for bulls from an unexpected quarter, after Brazil's government cut to zero, from 6%, a financial transactions tax, called the IOF, which was intended to discourage foreign investment inflows and slow appreciation of the real.
In fact, depreciation of the real has now become the problem, with the currency losing 8% of its value against the US dollar over the last three months.
And real weakness has in turn been a factor in undermining prices of the likes of arabica coffee and raw sugar, of which Brazil is the top producer and exporter.
It meant that, dollar-denominated, futures in New York needed to send a stronger signal to Brazilian producers to discourage production growth, in the face of ample supplies, than would otherwise have been the case.
