Procedures & Methodology

TSI's clearly defined and transparent methodology is the backbone of its iron ore, steel, scrap and coking coal prices. TSI was the industry pioneer in compiling prices based on actual spot transaction data gathered directly from industry participants throughout the supply chain. TSI applies its methodology consistently in the compilation of all of its indices around the world, providing clients with the confidence they need that all its prices are directly comparable.

Over 550 companies ('Data Providers') have registered and been approved to submit their pricing information to TSI and, in exchange, they see their data represented in the respective index. This offers significant advantages over traditional 'telephone polling' approaches: it is fast, secure, verifiable and enables Data Providers all over the world to submit data at their convenience. More information can be found in the documents below.

Regulatory Engagement

In 2014, Ernst & Young was engaged by Platts, TSI's parent company, to conduct an annual independent assurance review of its alignment to the IOSCO Principles for Oil Price Reporting Agencies (IOSCO PRA Principles).

The IOSCO PRA Principles, which set standards for governance and control systems, were introduced by the International Organization of Securities Commissions (IOSCO) and endorsed by the G20 in October 2012.

The reasonable assurance review by Ernst & Young was completed in February 2015 and included a comprehensive review of TSI's documentation of its processes for compiling benchmark prices used for iron ore, steel, coking coal and ferrous scrap contracts and observances of its practices in London and Singapore as at 28th February 2015.

The results confirmed TSI's alignment to the IOSCO PRA Principles. A reasonable assurance review is the highest standard for such a review.
