Greek factor causes jitters The olive oil trade is in "a very very nervous" state thanks to the "Greek factor", with yields from Greece lower than expected. Prices over the past few weeks have leapt up by more than 20% ­ but one trade source contested views that there had been an easing of prices. "There have been reports around of prices easing, but only certain grades of oil have come down. There has been no easing of the price of extra virgin yet which is still seeing significant premiums," said the source. "And of course the strength of sterling has not been working our way. "There are great concerns about Greece which hasn't had very good yields. And we will be very very nervous until January when the picture ­ and the situation in Spain ­ will be clearer." {{CANNED GOODS }}
