When conversations turn to the origins of credit ratings, names associated with bond markets and sovereign risk assessments often dominate the narrative. Yet, long before formal rating scales like AAA or AA+ became standard, the foundations of credit assessment were already being laid. At the centre of that early evolution sits Dun & Bradstreet, a firm whose influence predates and, in many ways, enabled the modern credit rating industry. 

The Origins of Credit Intelligence

The story began in the 19th century with the formation of R.G. Dun & Company, one of the earliest enterprises dedicated to gathering and distributing information about the creditworthiness of businesses. Dun & Bradstreet traces its origins to this firm, which later merged with The Bradstreet Company to form the modern entity. At a time when commerce was expanding rapidly across regions, merchants faced a simple but critical challenge: who could be trusted to pay their debts?

To address this, early credit reporters built networks of correspondents who collected information on businesses, ranging from financial strength to reputation and payment behaviour. This information was compiled into ledgers and shared with subscribers, effectively creating one of the first structured systems for assessing credit risk.

From Ledgers to Systems

What distinguished Dun & Bradstreet was not just the information it gathered but how it standardised and distributed it. By turning scattered observations into organised credit reports, the firm introduced a level of consistency and comparability that had not previously existed.

This was a pivotal shift. Credit decisions were no longer based solely on personal relationships or informal judgements; they could now be supported by documented insights. In essence, Dun & Bradstreet transformed credit from an intuitive practice into a more systematic process.

Not Quite a Rating Agency, But Foundational

It is important to draw a clear distinction. Dun & Bradstreet did not originate the modern credit rating scale used today for sovereigns and large corporations. It did not assign structured ratings like AAA or BBB, nor was it primarily focused on bond markets.

Instead, its core contribution lies in commercial credit reporting, particularly for businesses, including small and medium-sized enterprises. Its reports provided detailed assessments rather than simplified rating symbols and views.

However, this does not diminish its role. On the contrary, the systems it pioneered laid the groundwork for what would later evolve into formal credit rating methodologies. Without standardised information, the development of rating scales and comparative credit analysis would have been far more difficult.

Bridging Information and Markets

As financial markets matured in the early 20th century, the need for simplified, widely understood measures of credit risk grew. This led to the emergence of specialised rating institutions, which introduced the now-familiar alphanumeric rating systems.

These institutions built upon a foundation that Dun & Bradstreet had helped establish: the idea that creditworthiness could be systematically assessed, documented, and shared at scale.

Enduring Relevance

Today, Dun & Bradstreet remains a key player in the global credit ecosystem, particularly in the area of business credit intelligence. Its data and analytics continue to inform lending decisions, supplier relationships, and risk management practices worldwide.

While it may not be a “rating agency” in the modern sense, its legacy is unmistakable. It represents the transition from informal trust-based commerce to structured, data-driven credit evaluation.

By formalising how credit information is gathered and shared, it laid the intellectual and operational foundation upon which the modern credit rating industry was built.

In many ways, the story of credit ratings does not begin with the ratings; it begins with the systems that made them possible. And in that story, Dun & Bradstreet holds a central place.
