Share of Bitcoin in Banks' Crypto Portfolios Decreased, Altcoins Increased

New data regarding the activities of banks in the cryptocurrency market has been published. According to the statistics of the Basel Committee on Banking Supervision covering the second half of 2025, there have been significant changes in the distribution of crypto portfolios of banks, especially in the American continent.

The data showed that Bitcoin's weight in crypto positions held directly by banks and subject to capital adequacy rules has decreased sharply.

While the share of Bitcoin in these positions in banks in America was 75.8 percent in June 2025, it decreased to 44.2 percent at the end of the year.

After the decline in Bitcoin, the biggest increase was seen in Ether. Ether's share increased from approximately 22 percent to 38.5 percent during the same period.

Solana and XRP also entered the list

The diversification of banks' crypto positions is not limited to Ether.

As of December 2025, Solana's share reached 7.8 percent and XRP's share reached 5.6 percent. While the rate of Ethereum Classic was approximately 3 percent, the total share of other cryptocurrencies remained around 1 percent.

Thus, cryptocurrencies other than Bitcoin and Ether became more visible in the positions of American banks.

The data does not directly show how much Bitcoin banks sold or how many altcoins they purchased during the period in question. However, the change in portfolio distribution reveals that while the weight of Bitcoin decreased, the share of Ether, Solana and XRP increased significantly.

Customer-side activities increased by 93 percent

Another striking data in the report was seen in the crypto activities carried out by banks on behalf of their customers.

The size of customer-related crypto activities of banks in America increased by 93 percent in the second half of 2025, reaching 6.42 billion euros.

This figure was at 3.32 billion euros in June 2025.

On a global scale, banks' customer activities reached 9.38 billion euros. In June, this figure was 6.82 billion euros, and at the end of 2024 it was 5.49 billion euros.

In Europe, a movement in the opposite direction was observed. The size of crypto activities carried out by banks on behalf of their customers decreased by 25 percent to 1.93 billion euros.

The figure for the rest of the world was 1.03 billion euros.
