On May 21, 2026, U.S. lawmakers introduced the American Reserve Modernization Act (ARMA), which sets a goal of building a one‑million‑Bitcoin federal reserve within five years using only existing holdings and seized assets. The proposal is framed as budget‑neutral and avoids Treasury buy programs, contrasting with Sen. Cynthia Lummis's BITCOIN Act proposal of 200,000 BTC per year for five years. The U.S. government was reported to hold 328,372 BTC as of February 2026, with Bitcoin later cited around $76,000.

Intesa Sanpaolo reported $235 million in crypto assets as of March 31, 2026, rising from $100 million at end-2025, while several European peers rolled out trading, custody, and stablecoin initiatives. BBVA enabled 24/7 Bitcoin and Ethereum trading in its Spanish app, BPCE opened crypto access via Hexarq with a stated reach of 12 million clients, and a 12-bank group formed Qivalis to pursue a euro-denominated stablecoin.

BlackRock launched its staking-enabled Ethereum ETF, ETHB, on March 17, 2026, following a joint SEC and CFTC interpretive release stating staking rewards are not securities. Grayscale's ETHE, live since October 2025, distributed $9.4M in rewards for Q4 2025. Filings cited net shareholder yield estimates of 1.9%–2.6% APY after fees and custody.

TRM Labs data published in May 2026 says North Korea was linked to $577 million of the $651 million lost to crypto hacks in January–April 2026, or 76% of the total. The losses were concentrated in two April incidents attributed to Lazarus subgroup TraderTraitor: $285 million from Drift Protocol on April 1 and $292 million from Kelp DAO on April 18–19.

Intesa Sanpaolo disclosed that its crypto-related holdings rose from about $100M in Q4 2025 to roughly $235M in Q1 2026, including Bitcoin ETFs and new exposure to Ethereum and XRP. The filing also shows a new $95.9M call option tied to BlackRock’s IBIT, alongside increased positions in ARK 21Shares Bitcoin ETF and IBIT shares. The positions are described as proprietary trading on the bank’s own balance sheet, not a client product.

U.S. spot Bitcoin ETFs saw $1.8B in net redemptions over six trading days in May 2026, including a $648.64 million outflow on May 18 led by BlackRock’s IBIT at $448 million. Total net assets slipped below $100.49 billion as inflation data and U.S. legislative developments weighed on risk appetite.

A cluster of three DeFi exploits in May 2026 caused reported losses of $23.2 million across THORChain, Verus-Ethereum Bridge, and Echo Protocol. The incidents were dated May 15 ($10.8M), May 18 ($11.58M), and May 18-19 ($816K), with Echo's attacker also minting 1,000 eBTC at a nominal $76.7M that could not be fully realized due to limited liquidity.

Euro-denominated stablecoins expanded from $69 million to $777 million in monthly volume between January 2025 and March 2026. The increase was reported in TRM Labs’ Q1 2026 Global Crypto Adoption Index, published on April 23, as MiCA implementation advances and bank-led consortium Qivalis targets a euro stablecoin launch in the second half of 2026.
