According to institutional insights, Wall Street's entry into cryptocurrency is not an overnight development, but rather a gradual infrastructure buildout over the past decade. While the public focuses on price cycles, major banks have quietly constructed regulated custody, compliance, and risk management systems designed for scale. Recent clarity in the regulatory environment, including ETF approvals, has catalyzed a shift from the preparation phase to actual deployment. Institutions' long-term goal is to tokenize traditional assets such as stocks and bonds, which is expected to structurally reshape markets through near-instant settlement and reduced intermediaries. This phase represents a compounding transformation, rather than a short-term cycle.
