Due to poor Israeli harvest, olive oil prices to rise 20 percent
Whenever a poor harvest pushes olive-oil prices up, the report points at drought or a hot spring. True enough — but the biggest driver is quieter and built into the tree itself, and it explains why olive oil will never be a cheap, steady commodity.
The news is always the same shape: a bad harvest somewhere, and olive-oil prices tipped to jump. It is easy to read as a one-off caused by this year’s dry winter or hot spring. But olive-oil prices swing for reasons that go deeper than any single season, and understanding them tells you more than any price forecast — starting with a habit of the tree that no farmer can fully tame.
The tree’s own boom and bust
The olive is an alternate-bearing tree: a heavy crop one year tends to be followed by a light one, as the tree exhausts and then recovers itself. This biennial rhythm is built into the plant, and it means supply naturally lurches up and down even in perfect weather. Growers fight it with pruning and thinning, but they never abolish it. Half the ‘shock’ of a poor harvest is simply the down-swing of a cycle that was always coming.
Weather at the worst moment
On top of that rhythm sits the weather, and timing is everything. A dry winter starves the tree of the water it banks for the year; heat or wind during the brief spring flowering can wreck pollination before a single fruit sets. Because so much of the crop’s fate is decided in a few weeks of bloom, one badly timed hot spell can cut a harvest sharply — which is why forecasts made months ahead are so often wrong in both directions.
| What moves the price | Why | Can the grower control it? |
|---|---|---|
| Alternate bearing | The tree crops heavy then light by nature | Only partly — pruning softens it |
| Winter rainfall / drought | Sets the water the tree has to work with | No — irrigation helps where it exists |
| Weather at flowering | Heat or wind ruins pollination and fruit set | No |
| Labour and energy costs | Picking and milling are costly | Somewhat |
| Global stocks | One region’s shortfall lifts world prices | No |
What a buyer should take from it
Two lessons. First, olive oil is a farm juice with a volatile, weather-and-biology-driven supply — not a stable industrial commodity, and its price will always jump around. Second, when prices spike, that is exactly when adulteration and quiet down-grading creep in, as cheaper oils get blended in to hold a price point. Read our note on what an olive really costs: a suspiciously cheap ‘extra virgin’ in a bad harvest year deserves suspicion.
Reading an olive-oil price story
- Expect swings — alternate bearing guarantees them.
- Watch flowering-season weather, not just annual rainfall.
- In a short year, be extra wary of cut-price ‘extra virgin’.
- Judge value over seasons, not a single harvest’s headline.
Why olive-oil prices rise and fall: common questions
Why do olive-oil prices change so much?
Because supply is volatile by nature: olive trees alternate-bear, cropping heavy one year and light the next, and weather at flowering can make or break a harvest. It is a farm product, not a steady industrial commodity.
What is alternate bearing?
The olive’s built-in tendency to follow a heavy crop with a light one as it exhausts and recovers. Pruning and thinning soften the swing but never remove it, so supply rises and falls even in good weather.
How does weather affect the harvest?
A dry winter limits the tree’s water, and heat or wind during the short spring flowering can ruin pollination before fruit sets. Much of the crop is decided in a few weeks of bloom.
Should I worry about quality when prices spike?
Yes. Price spikes are exactly when cheaper oils get blended in and grades quietly slip. A very cheap ‘extra virgin’ in a poor-harvest year deserves scepticism.
Will olive oil ever be cheap and stable?
Not reliably. Its supply depends on a biennial tree and fickle spring weather across a few regions, so meaningful price swings are a permanent feature, not a glitch.
Whenever a harvest fails, everyone blames the sky, and the sky deserves some of it. But the olive was always going to give you a big year and then a small one — that is just what the tree does. What I watch in a short year is not the price rise, which is honest, but the bottles that somehow stay cheap. That is where the corners get cut. Pay the fair price in a lean year, or ask hard questions of the one that hasn’t moved.
