Semiconductor PPI Chart

It is a monthly index published by the U.S. Bureau of Labor Statistics measuring the prices US producers receive for semiconductors and other electronic components. This page charts the NAICS 3344 industry index, distributed through the St. Louis Fed FRED service. The latest reading is 73.1 for July 2026.

For July 2026 the index stands at 73.1, which is +27.1% year over year and -0.6% month over month. Producer prices are therefore higher than a year earlier.

The index is scaled so that December 1984 equals 100. A reading of 73 means producer prices for this industry are about 27 percent below their December 1984 level in index terms. Because the index reflects quality-adjusted prices over four decades of semiconductor improvement, the absolute level matters far less than its direction and rate of change.

Use year over year for cycle direction because it removes seasonal timing. Use month over month to spot turns early, accepting that single months are noisy and get revised. The index level is mainly useful for comparing against its own history rather than as a price.

Advanced view adds 3-, 6-, and 12-month simple moving averages plus a 6-month band at two population standard deviations, and an optional month-on-month sub-panel. Moving-average periods are calendar months. They are descriptive overlays calculated from published observations, not forecasts.

Yes. Export CSV downloads every published month with the index value and the calculated month-over-month and year-over-year changes. The underlying index is public BLS data redistributed through FRED.

Not any more. BLS discontinued its memory and microprocessor product-line index in 2015, and no memory-specific or DRAM-specific PPI series is currently published. Any chart claiming to show a live memory PPI is showing something broader.

Because it tracks memory far better. Measured against this site's own Korea customs memory unit-value series, the NAICS 3344 electronic-component index moves with memory prices, while the narrower Semiconductor and Related Device Manufacturing index has recently moved in the opposite direction. The narrower index carries the word semiconductor but is dominated by logic, analog and discrete devices, so it is the worse memory proxy despite the better-sounding name.

Output of US establishments manufacturing semiconductors and other electronic components. That includes integrated circuits, printed circuit boards, connectors, capacitors, resistors and similar components. It is a basket, not a single product, and it is not a memory-only measure.

No. PPI measures prices received by domestic US producers for output sold in the United States. Much of the world's memory is manufactured in Korea, Taiwan, Japan and China, so this index captures the US producer slice rather than the global market.

They answer different questions and are kept on separate pages for that reason. The Korea chart is a customs unit value in dollars per kilogram covering Korean memory exports. This chart is a US producer price index covering a broad component basket. They are separately sourced and separately labelled, and neither is used to adjust the other.

From the U.S. Bureau of Labor Statistics Producer Price Index program, retrieved through the Federal Reserve Bank of St. Louis FRED API. Your browser does not contact BLS or FRED while viewing this page; it reads a published snapshot from this site.

The reference month is published roughly two weeks later, so the figure shown is for a month that has already ended. On top of that publication lag, producer prices themselves reflect negotiated and contract transactions, so they turn more slowly than spot markets. Treat this as confirmation of a trend rather than an early warning.

Yes, and substantially more than most series. Effective with data for November 2021, each index undergoes five iterative updates: it is recalculated for three interim months after first issuance and posted as final four months after original publication. Recent months on this chart should therefore be read as provisional.

No. The published series is not seasonally adjusted, which is why year-over-year comparison is the safer way to read direction. A single month-over-month move can reflect seasonal timing rather than an underlying price change.

Producer price indexes adjust for quality change. When a newer component delivers more capability for the same money, part of that is recorded as a price decline rather than a product change. Over decades this produces a long downward drift in semiconductor indexes even through periods when buyers pay more for a given part.

The collector runs monthly after the BLS release window and republishes the snapshot atomically. Every stored month is kept as an immutable revision, so a revised print is added rather than overwriting the original figure.

Not reliably. It measures US producer selling prices for a broad component basket, while retail memory prices reflect a different product mix, different geography, distribution margins and promotional cycles. This site charts retail prices separately and does not claim one series mechanically drives the other.

Because the basket, geography, quality adjustment and revision schedule all differ from any single product price. A broad US producer index can rise modestly while a specific memory contract price doubles, or fall while headlines report shortages. Disagreement is normal and is usually a composition difference rather than an error.

No. This is a descriptive chart of a public statistical series. It does not recommend securities, forecast earnings, time a purchase, or explain why any market moved. Use primary company disclosures and specialist pricing sources for decisions that need those claims.
