This is a cyclic commodity weather/fungus dependent.. There is an increasing suplus of Arabica which is expected to last atleast 2 yrs if not more unless Brazil has a crop failure ( low probability due to their ability to aerially spray.)
Take a look at the 30 year historical price of coffee and look at how the preceding price spikes played out.
Coffee might have bottom out for now, but it does not mean the price will shoot back up. Price recovery or crash will likely depend on next years crop outlook.
