What Is ENAG?

ENAG (Enflasyon Araştırma Grubu, "Inflation Research Group") is an independent group formed voluntarily by academics and researchers in Turkey. It computes and publishes its own inflation rate as an alternative to the state's official inflation. It is not an official body; its figures are not counted as Turkey's official statistic. Turkey's official inflation is published by TÜİK.

What does ENAG do?

ENAG builds its own consumer price index to measure the change in consumer prices. This index is often referred to as E-TÜFE. From it, the group publishes monthly and annual inflation rates.

In short, ENAG offers a second reading of how to measure inflation. Inflation is the pace at which the general price level rises over time; a measure is obtained by comparing the price of a "basket" of goods and services from one period to the next. ENAG builds such a basket too, but its contents and weights need not be identical to the official measure.

How does it differ from TÜİK?

The core difference is source and method. ENAG gathers prices largely online, pulling them from e-commerce sites and online markets through automated "web scraping." TÜFE (the Consumer Price Index) is computed by TÜİK using field collection and weights based on the Household Budget Survey.

For this reason the two measures can produce different results for the same period:

• Basket: Which products and services enter the measure can differ.
• Weights: Each item's share in the basket (for example the weight of food) can differ, which can widen the gap in headline inflation.
• Data collection: Focusing on online prices can lead ENAG to collect data at a different speed and scope.

These differences stem from technical choices. This page takes no side on which measure is "correct"; it describes both as they are and leaves the judgment to the reader.

Is ENAG official?

No. ENAG is an independent research group, not a government body or official statistical authority. In Turkey the authority to publish official inflation data rests with TÜİK. Although ENAG's figures are frequently cited in public debate, they do not carry the status of an official statistic. This matters, because contracts, rent increases and many official calculations are tied to the rate TÜİK publishes, not ENAG's.

Relationship to fund returns

When you assess what a fund has earned, nominal return (the raw percentage) and real return (return adjusted for inflation) are different things. Real return divides the nominal return by an inflation rate to show the true change in purchasing power. Here, which inflation measure you use directly affects the result.

On Fon.org.tr, several bases are offered for real return: TÜFE as the official measure and, alongside it, ENAG as an alternative base. This lets you see a fund's return side by side under two different inflation measures and observe for yourself how the choice of measure changes the outcome. The aim is not to present one measure as superior to the other, but to place both in front of you transparently.

Summary

ENAG is an independent inflation measure computed by academics as an alternative to official inflation. It is not official and can produce results that differ from TÜİK's TÜFE. Because the base you choose changes the result in a real-return calculation, being able to see both measures makes comparison easier.
