Global asset manager Franklin Templeton has filed an application with the US Securities and Exchange Commission to launch a crypto index Exchange-Traded Fund (ETF) that would track a broad ­basket of major digital-assets including Bitcoin and Ethereum. The proposed ETF signals increasing institutional absorption of crypto assets and regulatory acceptance in major markets. Analysts say such product launches could attract fresh capital flows into crypto markets, though significant hurdles around valuation, custody and regulation remain ahead before final approval is granted.
