Export Price Index: Pricing US Goods Abroad

Key Takeaways

• The export price index tracks the average price change of goods and services the US sells abroad.
• A weaker dollar can lift export prices in dollar terms and improve competitiveness.
• Compared with import prices, it shows the terms of trade, a key driver of trade balances.
• Agricultural and industrial commodities can dominate the headline's swings.

What It Is

The Export Price Index is one half of the Import/Export Price Indexes, published monthly by the U.S. Bureau of Labor Statistics (BLS) through its International Price Program. It measures the average change over time in the prices US sellers receive for nonmilitary goods and services sold to foreign buyers.

Where the import index captures the cost of what the country buys from abroad, the export index captures the price of what it sells. Read side by side, the two indexes describe how a dollar of US output trades against a dollar of foreign output, a relationship economists call the terms of trade.

The Intuition

US exporters compete in global markets where price matters. When the prices American producers can charge abroad rise, exporters earn more per unit, which supports revenue and can signal strong foreign demand or higher production costs being passed through.

Currency plays a central role. A weaker dollar can make US goods cheaper for foreign buyers in their own currency while still letting exporters raise dollar prices, improving competitiveness. The export price index, set against the import price index, shows whether the country is getting more or less foreign output for each unit it ships out, which feeds directly into the trade balance and into corporate earnings for exporters.

How It Works

The BLS collects prices for a sample of exported items, holding product characteristics fixed so the index isolates pure price change. Those prices roll up into category indexes weighted by export trade values.

The program uses a modified Laspeyres formula. As with the import index, the BLS in 2025 incorporated high-quality unit-value indexes drawn from administrative trade records to replace some directly collected survey prices in the official calculations. Both monthly and year-over-year figures are published.

Export price inflation (YoY) = ((Export price index this month / Export price index same month last year) - 1) * 100

Computing the terms of trade is straightforward once both indexes are in hand:

Terms of trade = export price index / import price index

The release lands mid-month at 8:30 a.m. Eastern, covering the prior month, published together with the import index.

Worked Example

Suppose the all-exports price index reads 130.0 this month and the all-imports index reads 132.0. The terms of trade ratio is:

130.0 / 132.0 = 0.985

A ratio below 1.0 here simply reflects the relative index levels, but the change over time is what matters. If next year exports rise to 136.0 while imports stay at 132.0, the ratio improves to 1.03, meaning each unit of US output now buys more foreign output than before. That improvement supports the trade balance and tends to lift earnings for export-heavy industries, which investors watch closely.

Common Mistakes

1. Reading the level instead of the change. The index level alone says little. What matters is the percent change over time and how it compares with import prices.

2. Ignoring the currency channel. A falling dollar can lift dollar-denominated export prices even when foreign-currency prices are flat. Skipping the exchange-rate context distorts the read.

3. Forgetting the commodity tilt. Agricultural and industrial materials carry heavy weight. A grain or metals swing can dominate the headline and mask other categories.

4. Treating it as a domestic inflation gauge. Export prices are paid by foreign buyers. They feed terms of trade and exporter revenue, not the prices US consumers face.

5. Overlooking the import pairing. The export index is most informative against the import index. Reading it alone misses the terms-of-trade story it is built to tell.

Frequently Asked Questions

What is the export price index in simple terms? The export price index measures how the prices of goods and services the United States sells to other countries change over time. It is the counterpart to the import price index.

How does the export price index affect investment decisions? Rising export prices can boost revenue for export-heavy companies and signal improving terms of trade, which supports the trade balance. Investors use it alongside the dollar and import prices to gauge the outlook for exporters and the currency.

What is a real-world example of the export price index mattering? When a strong harvest and firm global demand push US agricultural export prices higher, the export index climbs, lifting revenue prospects for agribusiness and improving the country's terms of trade.

How can investors use the export price index effectively? Compute the terms of trade by dividing export prices by import prices and track its direction, while watching the dollar and commodity-heavy categories that drive much of the index's movement.

How is the export price index different from the import price index? The import price index measures prices the United States pays for foreign goods, while the export price index measures prices it receives for goods sold abroad. Their ratio defines the terms of trade.
