Coffee beans are in short supply right now and it’s injected some life into the coffee exchange traded note (ETN) as a result.

Brett Arends for The Wall Street Journal reports that the shortage has meant that prices for arabica beans—the kind used in a decent cup of roast coffee—have jumped by more than a third in the past few months to multi-year highs. [Coffee ETN Gets Its Fix.]

Fueling the price spike further is a weak harvest and a world growing increasingly full of coffee drinkers. Brazil’s harvest may be the savior and ease things, but the catch is that Brazil tends to keep a lot of its crop for itself an the crop is expected to be lower than in years past, anyway.

So far, a pound of Arabica sold for as little as $1.30 earlier this year; the latest price: around $1.80. iPath Dow Jones AIG Coffee TR Sub-Index ETN (NYSEArca: JO) has responded in kind: year-to-date, it’s up 33.5%. Coffee futures also account for 11% of PowerShares DB Agriculture (NYSEArca: DBA), which is up 2.3% year-to-date.
