··20032000s commodity super-cycleCorrelationExpected causation
China's post-2001 WTO-driven infrastructure boom, alongside strong global growth, drives the IMF commodity price index up roughly fourfold between January 2000 and mid-2008; crude oil rises from about $30/barrel in 2003 to a record $147/barrel on 11 July 2008, delivering a sustained fiscal windfall to every oil exporter in this database (Iran, Saudi Arabia, Venezuela, Russia) before the Global Financial Crisis abruptly ends the cycle.
Why this link: Oil-funded fiscal and monetary expansion during the super-cycle is a widely cited driver of Iran's persistently elevated inflation rate in the mid-to-late 2000s.
Caveat: Inflation in Iran has many structural drivers (subsidies, exchange-rate pass-through, liquidity growth); the oil cycle is one contributing channel among several.
Lag: 1-2 years.Source: US Energy Information Administration012018US withdraws from the JCPOACorrelationExpected causation
President Trump announces US withdrawal from the Iran nuclear deal and directs the phased reimposition of all sanctions lifted in 2015-16, with full "snapback" effective 5 November 2018, reversing the 2015 sanctions-relief framework and re-isolating Iran's oil and banking sectors from the dollar system.
Why this link: The sanctions-driven rial collapse fed through into a sharp acceleration of consumer-price inflation from 2018 into 2019-2020, a well-known exchange-rate pass-through channel.
Caveat: Money-supply growth and subsidy/energy-price adjustments in late 2019 also contributed independently to this inflation surge.

1944CorrelationExpected causationBylaw Concerning Coupons and Rationing Booklets
Regulates the use of coupons and rationing booklets for distributing rationed goods.
Why this link: As a formal price/quantity-control regime on staple goods, this 1944 bylaw is historical context for Iran's long-run inflation and price-control story, even though it predates the modern CPI series carried on the site.
Caveat: No CPI series on the site covers 1944; this link is contextual, not measurable against a specific chart series.
Lag: Not applicable, historical context only.1995CorrelationExpected causationRuling No. 61 of the General Board of the Administrative Justice Court ... Board of Directors of the Post Company Concerning Telecommunications Service Tariffs
This is General Board Ruling No. 61 of the Administrative Justice Court concerning a decision of the Post Company's board of directors on telecommunications service tariffs.
Why this link: This 1995 Administrative Justice Court ruling addresses the Post Company's telecommunications service tariffs, a regulated communications price feeding into the price index and telecom-sector cost structure.
Caveat: A narrow, sector-specific tariff dispute from the pre-mobile-telecom era; its weight in the aggregate price index is minor and cannot be isolated from broader inflation drivers of the mid-1990s.
Lag: Short, within months of the ruling.2004CorrelationExpected causationRuling No. 187 of the General Board of the Administrative Justice Court ... Operational Regulations and General Conditions of Water and Wastewater Tariffs
This is General Board Ruling No. 187 of the Administrative Justice Court concerning operational rules and the general conditions for water and wastewater tariffs.
Why this link: This 2004 Administrative Justice Court ruling addresses the terms and general conditions of water and wastewater tariffs, a regulated household utility price that feeds into the consumer price index.
Caveat: A single adjudication on tariff terms for one utility; its weight within the broader CPI basket is small and cannot be separated from the many other administered-price changes each year.
Lag: Short, within the billing cycle following the ruling.2007CorrelationExpected causationExecutive Bylaw of the Unorganized Monetary Market Regulation Act
Implements the Act on Regulating the Unorganized Monetary Market by requiring non-bank credit and financial institutions, currency exchange bureaus and leasing companies to obtain a license from the Central Bank of Iran and comply with its prudential and capital rules, bringing informal money-lending and credit activity under Central Bank supervision.
Why this link: As a national-scale regulation of informal money markets, this law is a major channel into Iran's broader monetary aggregates, interest-rate structure, and consequently the inflation dynamics that a large, price-setting informal credit market can amplify.
Caveat: Monetary aggregates, interest rates, and inflation in Iran are shaped by many larger forces, government deficit financing, sanctions, exchange-rate pass-through, so this law's specific contribution is real but cannot be isolated from those.
Lag: 1-3 years, diffuse.2021CorrelationExpected causationRuling No. 1362 of the General Board of the Administrative Court of Justice ... on the Determination of Sand and Gravel Prices by the Aforementioned Working Group
This ruling by the General Board of the Administrative Court of Justice addresses the determination of sand and gravel prices by the relevant working group.
Why this link: This 2021 court ruling annulled a working group's authority to set prices for sand and gravel, a specific construction input; the database holds no dedicated construction-materials price series, so its closest, weak connection is to Iran's general price indices.
Caveat: Sand and gravel are a minor share of the CPI/WPI basket, and this ruling only removes one agency's price-setting power rather than changing supply, demand or cost conditions, so any effect on general price indices is negligible and not separately observable.
Lag: None separately observable.2022CorrelationExpected causationRuling No. 763 of the General Board of the Administrative Court of Justice ... on the Minutes of the Market Regulation Working Group Session Dated 11 Azar 1398 (2019)
This ruling by the General Board of the Administrative Court of Justice concerns the minutes of a Market Regulation Working Group session held on 11 Azar 1398 (2019).
Why this link: This 2022 court ruling concerns decisions of a market-regulation working group, a body involved in administrative price interventions, giving it a weak, general connection to Iran's price-index series.
Caveat: The ruling addresses one working group's procedural authority, not the price level itself, so no measurable effect on CPI or WPI can be attributed to it.
Lag: None separately observable.
