Fuel prices bouncing back up

Around six months ago I posted graphs of the Singapore spot prices converted to New Zealand dollars of aviation jet fuel and residual fuel oil (RFO) used in ships. The updated graphs through to June 2009 that follow illustrate how these spot prices have been rising in recent months.

Again I have used monthly data from the Reserve Bank of New Zealand for the foreign exchange rates and from the US Energy Information Administration for the fuel spot prices.
