The relationship between stocks and crypto markets is likely to be weakened in the future, Wall Street Bank Citi (C) said in a research report on Monday.

While stocks have been and remains the most important macro driver in crypto markets, “Equity-Crypto correlation will probably fall over time as the beginning asset class matures, the investor base is growing, technological advances and adoption progress,” the report said.

Still, the speculative nature of cryptocurrency markets means that risk-active corrections may be bloated, especially during risk-off events, the bank said.

“A more transparent regulatory regime in the United States will also lead to more idiosyncratic price action,” wrote analysts led by Alex Saunders.

Bitcoin (BTC) volatility is expected to continue to fall in the long term as institutional adoption grows, the bank said.

Citi noted that Crypto was the only asset class whose market capital, as a percentage of US equities, grew over last year.

Bitcoin’s connection with gold is also worth tracking as it may be an early sign of the “Trusty Bearing Store,” the report added.
