Everyone is watching the price of oil. That makes sense. Oil is visible. You see it every time you drive past a gas station. The number is right there on the sign, updating in real time like a scoreboard for the global economy.
Almost nobody is watching the price of fertilizer.
That is a mistake. Because fertilizer is about to do to your grocery bill what oil already did to your gas tank. And unlike gas prices, which you see coming, fertilizer price increases show up on your receipt 6 to 10 weeks after the disruption, by which time it is too late to get ahead of them.
Why Fertilizer Matters
Modern agriculture runs on three primary fertilizers: nitrogen, phosphorus, and potassium. Without them, crop yields drop by 30 to 50%. That is not an exaggeration. It is the documented finding of the Food and Agriculture Organization of the United Nations.
The raw materials for these fertilizers are mined and manufactured in a handful of countries. The finished products are shipped globally. And a significant portion of that global trade transits through the Strait of Hormuz.
Here is the supply chain:
- Nitrogen fertilizer (urea, ammonium nitrate): The Middle East is one of the world's largest producers, because nitrogen fertilizer is manufactured from natural gas. Qatar, Saudi Arabia, and Oman are major exporters. Their shipments transit the Strait.
- Phosphorus fertilizer (DAP, MAP): Saudi Arabia is one of the top five global producers. Shipments transit the Strait.
- Potassium fertilizer (potash): Less directly affected by Hormuz, but shipping reroutes and elevated insurance costs still impact pricing.
The International Fertilizer Association estimates that approximately one-third of globally traded fertilizer either originates from or transits through the Persian Gulf region. When the Strait is blockaded, that supply is cut off.
What Has Already Happened
Fertilizer prices have already risen approximately 43% since the conflict began, according to commodity trading data tracked by the World Bank Commodities Markets Outlook. This is not a prediction. This has already happened.
But the effects have not reached your grocery store yet. There is a lag. Fertilizer purchased months ago is currently being applied to crops in the field. The crops being planted right now for summer and fall harvest are the ones affected by today's fertilizer prices.
The timeline works like this:
Now (March): Farmers are purchasing fertilizer for spring planting at prices 40%+ above last year. Some are reducing application rates to manage costs, which means lower yields.
April to June: Spring planting season. The amount and type of fertilizer applied now determines the yield in August through October.
July to September: If fertilizer application was reduced, crop yields will be measurably lower. Lower supply with constant or increased demand means higher prices at harvest.
September to December: Grocery prices fully reflect the higher input costs. Expect the most visible increases on produce, dairy (feed costs), meat (feed costs), bread and baked goods (wheat), and cooking oils.
What This Means for Your Grocery Budget
The USDA Economic Research Service is projecting food-at-home price increases of 3 to 5% above baseline for the second half of 2026 if the Hormuz disruption persists through spring planting season. If it persists longer, the increases could be higher.
For context, a 5% increase on a $900/month grocery budget is $45/month, or $540 over a year. That is on top of the energy cost increases already hitting households.
The categories that will be hit hardest:
- Fresh produce: Highest sensitivity to fertilizer costs and transportation costs (double impact)
- Meat and dairy: Animals eat grain. Grain requires fertilizer. The cost increase cascades through the feed supply chain.
- Bread, pasta, and baked goods: Wheat is one of the most fertilizer-dependent crops
- Cooking oils: Canola, soybean, and corn oil all depend heavily on fertilizer application rates
The categories that will be least affected:
- Canned goods (already processed and packaged at older prices)
- Frozen vegetables (same principle, existing inventory at older costs)
- Dried goods (beans, rice, lentils, oats: less fertilizer-intensive, more shelf-stable inventory)
What to Do About It
1. Buy Shelf-Stable Staples Now
This is the same advice we gave in our grocery strategy article, but the fertilizer data makes it more urgent. The shelf-stable staples you buy today are priced on pre-disruption input costs. The same items in three months will be priced on disrupted input costs.
Buy what your family actually eats. Rice, pasta, canned tomatoes, canned beans, oatmeal, cooking oil, flour, dried lentils. Two weeks ahead of your normal consumption is sufficient. You are not hoarding. You are buying at today's prices instead of September's prices.
2. Shift Toward Less Fertilizer-Dependent Foods
This is the non-obvious move. Some foods are less affected by fertilizer disruptions than others:
- Legumes (beans, lentils, chickpeas): These crops actually fix their own nitrogen from the atmosphere. They require less synthetic fertilizer than grains or vegetables. They are also among the cheapest and most nutrient-dense foods available.
- Root vegetables (potatoes, sweet potatoes, carrots): Less fertilizer-intensive per calorie than leafy greens or fruit.
- Eggs: Relatively efficient protein source, less affected by feed cost increases than beef or pork.
3. Consider a Small Garden
This is not a joke, and it is not survivalist fantasy. A 4x8 raised bed can produce a meaningful quantity of lettuce, tomatoes, peppers, herbs, and green beans from May through October. The seeds cost $20. The soil costs $30 to $50. The yield, at current and projected grocery prices, easily returns 10x that investment.
The USDA's People's Garden Initiative provides free resources for starting a home garden. Your local agricultural extension office (find yours at nifa.usda.gov) offers region-specific planting guides.
4. Lock In Prices Where Possible
If your grocery store offers loyalty programs, digital coupons, or price-matching, now is the time to use them aggressively. Some warehouse clubs (Costco, Sam's Club) allow you to buy bulk staples at locked prices. Buying a 25-pound bag of rice today at $15 is better than buying five 5-pound bags at $5 each over the next three months when the price may be $6 to $7.
The Bigger Picture
The fertilizer problem illustrates something important about this conflict: the effects are layered, delayed, and interconnected. Oil was the first wave. Fertilizer is the second. Medication availability is the third. Each wave hits households on a different timeline, and by the time you see the price increase on the shelf, the window to get ahead of it has already closed.
This is why the 90/14/500 framework exists. Ninety days of prescriptions. Fourteen days of pantry. Five hundred dollars in cash. It is not a doomsday plan. It is a buffer against exactly the kind of rolling, cascading disruptions that are happening right now.

Either way: buy the rice, plant the garden, and pay attention to the fertilizer market. Your grocery bill in September depends on what you do this week.
