The provided primary sources, which are all high-authority speeches and testimonies from Governor Waller, consistently and strongly support the substance of the statement. While he may not use the exact word "integrated" in every instance, the concepts he discusses are predicated on the fact that cryptocurrencies are connected to and have an impact on the traditional financial system.The most compelling evidence comes from his repeated focus on the "financial stability risks associated with crypto-assets" (Sources 1, 2, and 7). For crypto-assets to pose a risk to the broader financial system's stability, they must be connected or integrated in a meaningful way; an isolated system would not pose such a threat. This acknowledgment of risk is a de facto statement of integration.Furthermore, other speeches directly address the nature of this connection. His discussions explore "how crypto technologies fit into the existing payments system" (Source 4), the "intersection of certain digital assets with the established financial system" (Source 7), and whether decentralized and centralized finance are "Substitutes or Complements" (Source 5). These topics inherently assume a level of interaction and integration. There is no conflicting evidence among the relevant sources. The collective weight of his remarks across multiple years confirms he views crypto not as a separate ecosystem but as one whose activities and risks are intertwined with the financial system he oversees.
