The chart illustrates the changes in the global

food

price

index

and the average

oil

price from 2000 to 2011. It is evident that, despite experiencing several notable fluctuations, both

food

and

oil

costs saw a significant

overall

increase over the eleven-year period. The trends for both commodities are very similar, suggesting a strong correlation. In 2000, the

food

index

and the average cost of

oil

were relatively low, with the former standing at approximately 90

points

and the latter around 30

dollars

per barrel.

Subsequently

, by mid-2008, both indices had risen considerably, with the

food

index

reaching around 220

points

and the average

oil

cost climbing to 130

dollars

per barrel.

However

, after a marked decline in 2009—where the

food

index

dropped by over 80

points

to 140

points

, and

oil

costs fell sharply by around 90

dollars

to 40

dollars

per barrel—both indices surged once again from 2009 to 2011.

Although

they reached their highest

points

in different years—with

oil

peaking at roughly 130

dollars

in mid-2008 and

food

reaching its maximum at almost 240

points

in 2011—both commodities exhibited a remarkably similar trend over the period, with a correlation rate of 93.6%.
