The Federal Reserve's new Financial Vulnerability Index (FVI) indicates that despite firm spot demand for Bitcoin, the financial system's capacity to amplify shocks is increasing. The FVI's aggregate index is 0.65, with valuation pressure at 0.77 and funding risk at 0.62, all deemed "notable." Financial leverage stands at 0.83, categorized as "elevated." These metrics suggest that accumulated leverage and risk-taking could magnify future market shocks, posing risks to Bitcoin's current rally, which saw it touch $86,000 on Sept. 21.
