The short answer.
The Nexus cycle, seen from GRA, is the eight-step path by which a question becomes evidence, a Foundry build, an organized community, a Universe test, a Nexus Reports publication and a decision by competent actors. GRA brings the financial sector's questions, contributes aggregated sector understanding and prepares readiness files for independent review; it never approves, lends or invests.

Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Nexus cycle | The eight-step loop by which work moves in every Nexus field: question, evidence, build, organize, test, publish, decide and renew, each step with a named owner. |
| Readiness file | A document set describing a programme's evidence, risks, governance and data so that a competent institution can carry out its own independent review; it is not an approval, rating or offer of finance. |
| Competent authority | The body that a law or regulation designates to exercise a given power or duty, such as a supervisor, a civil protection agency or a ministry; only it can take the decisions the law assigns to it. |
| Transmission channel | The route by which a shock reaches financial institutions' balance sheets. |
