It might be appropriate, at this point, to compare exchange rates to a basket of currencies/commodities - both the Euro and the US Dollar are highly unstable right now, moving in opposite directions. Any opinions on a stable index which which to measure Australian and other currency fluctuations?

This is one of the more interesting aspects of this years petrol prices here in OZ. Last year we had higher petrol prices, at least here in Albury Wodonga, even though oil prices only got to US$78 bbl. This year with oil sitting at $90+ we a re still holding to A$1.40 a litre, slightly lower than last years highs of $1.46.

Does anyone know of a source of historical oil price data that can be corelated to the movement of the AUD against the US. I am happy to produce the chart if you send me the data?

Also note crack spread on oil to unleaded has narrowed than in the past.
