Information “Basket of TFE substances” by TK


TK has published a public announcement on its website about the transition to a more detailed index publication (COICOP 5) instead of the price differential based on items in the Consumer Price Index (TFE) item basket.

The announcement stated that, as in all the statistics published by TA as part of the Official Statistics Program, the TFE has been calculated and published in line with international norms and standards, taking into account all the European guidelines of Statistical Practice.

In the notice published on the site under the principles of “accessibility and openness”, which are also defined in the framework of the TA Quality Assurance, all the details of the TFE data collection, processing and distribution processes, ” statistical production, in constant development and social, economic, technological change and develops and improves every day, according to the periodic conditions and the growing needs and expectations in this direction. ” the expression is used

In the announcement it was stated that the national statistical offices have been following closely the best practice examples and all these developments in order to respond to current conditions, market and user needs for all statistics they produce in accordance with the international standards and consequently, some tables and tables published as part of the TFE have been presented. market prices.

The announcement specified that it was decided not to update the results of the TFE of May 2022 from the date of publication, as the table on average prices of articles published monthly has caused misunderstandings and misleading assessments in the public, and the following have been noted :

“Instead, the scope of the Index Results by Expenditure Group table has been expanded and the publication of index results for 144 key topics has begun, which include more detailed index changes and correspond to COICOP level 5, instead of at the individual level Classification of consumption by purpose-level COICOP 4, starting from 2022. As part of the TFE, approximately 560,000 392 prices are compiled every month for the equivalent of 409 articles and 904 articles. of prices is executed at the level of “equal to the article” and there is hardly any country that publishes all the average prices in the world, it is in doubt that it is published at the level of “article” in our country. It is the main reason so the table is mispriced by the public. As a result, the price of the item presented to the public as an intermediate price of gasoline reflected the average price of all gasoline vehicles followed. This is valid for all non-homogeneous articles. Another example that can be given in this regard is the prices of fresh fruit and vegetables. Among the products with high price volatility in the changing seasons, the prices of fresh fruit and vegetables change weekly. a is filled in four times a month, once. The average price of vegetables and fresh fruit, which was compiled four times (every week) by our institution, was published in the price table for the subject. However, due to the public attention on (most up-to-date) prices in the last week, the prices of fresh fruit and vegetables, based on the average of the four weeks announced by our agency, have often been the subject of discussion, like other products. While the four-week average could be higher than last week’s price, in the early season months in general, in fresh fruit and vegetables, at the end of the season, the higher average prices could be compared to last week’s prices. there was criticism in the public opinion when the average price was higher than the prices of the last week per item, on the contrary, our institution was exposed to unfair criticism “.

– Situations of country prices publication

The announcement stated that most national statistical institutes around the world did not publish prices at the item level, due to the non-homogeneous nature of the products and the fact that monthly average prices may differ from market prices at the time of publication of the newsletter and, in this context, the European Union (EU) and candidate countries When the websites of 33 national statistical offices were also examined, including EFTA countries, the USA and Canada, it was found that no country published all prices at the item level.

In this context, in the announcement, it was pointed out that 17 of the countries concerned did not share price information in any way, 9 of them published the monthly average prices of the selected materials, 4 of them published the annual average prices of the materials. selected, and 3 of them only published monthly energy prices, the following information was provided:

“When we look at the index levels announced by related countries, we see that the information share about the index has intensified at the 4th and 5th COICOP levels. As of June 3, 2022, the TK has moved from COICOP 4 level to more detailed level COICOP level 5, as well as the monthly variation prices of the selected products.With the start of its publication in Turkey, in this field, transparent countries are included in the range between 33 countries between EU and candidate countries, EFTA countries, USA and Canada, based on general data.

– Inform the public about petrol and diesel prices

The announcement also specified that the prices of gasoline and diesel were compiled by the fuel points of sale by the TA regional directorates during the separate periods of compilation of the prices of the products, and the consumption of the related products was obtained from the administrative records of the daily amounts of sale of pumps received from the Energy Market Regulatory Authority (EMRA).

In the announcement, which indicated that the daily demand for these products, mainly due to daily fluctuations in gasoline and diesel prices, increased significantly before the price increase was generally reflected, the following assessments were included:

“The monthly average selling price of the products in question is calculated by weighting the daily consumption amounts with the daily prices. International applications also recommend that price change calculations be made on prices balanced with the amount of consumption, even though The difference between the “weighted average prices” obtained by including in the calculations of our Agency the daily consumption quota for the related products, from the surface prices obtained with the simple average calculation method compared to the “average daily prices” is due to the difference in the methodologies used The debates that emerged following the attempt to reach the price results for the same item, as in the EU member and candidate countries, EFTA countries, USA and Canada, it is important how accurate the TA decision is do not publish the prices of products other than selected homogeneous items. It is an indication “.
