One of Wall Street’s most storied institutions just put a number on Bitcoin’s place in the global financial system. And that number is surprisingly small.
Morgan Stanley’s Wealth Management division, through its Global Investment Office, published a framework assessing Bitcoin’s long-term return potential. The core finding: Bitcoin’s $2.2 trillion market cap as of October 2025 represents roughly 2% penetration into what the bank defines as a $130 trillion addressable market. That addressable market combines the global M2 money supply and gold, the two asset classes Bitcoin most directly competes with as a store of value.
The growth math Morgan Stanley is running
The bank’s research, originally published in its December 2025 AlphaCurrents Crypto report, lays out a range of scenarios tied to Bitcoin user growth over the next decade. In the most conservative case, where adoption essentially flatlines, the projected annualized return sits around 3%. Under aggressive adoption assumptions, that figure climbs to nearly 10%.
The middle ground is where it gets interesting. With no change in Bitcoin’s current penetration rate, the projected annualized return comes in at 6.4%. If user growth merely tracks global population growth, that ticks up to 7.2%. And if user adoption grows at 5% annually, the projected return hits 9.8%.
