The total market capitalization of cryptocurrencies fell by 20.4% to $2.4 trillion in the first quarter of 2026, marking a 45% decline from the peak in October 2025. According to PANews, the stablecoin market capitalization remained steady at $309.9 billion during the same period. Notably, Tether's USDT issuance saw a significant decrease of 1.6% to $184.1 billion, marking its first notable decline since the second quarter of 2022, while Circle's USDC increased by 2.4% to $77.1 billion. Bitcoin's price dropped by 22% over the quarter, underperforming major U.S. stock indices. Centralized exchange spot trading volumes decreased by 39.1% to $2.7 trillion.

Cryptocurrency consulting firm Novora has released its 2026 Investor Relations and Token Transparency Report, highlighting significant gaps in the disclosure of market-making arrangements among major crypto protocols. According to Foresight News, the report reviewed over 150 key crypto protocols and found that while market-making plays a crucial role in token trading, disclosures related to these arrangements are almost nonexistent. Less than 1% of the protocols disclosed terms related to market makers. Notably, only one protocol, the decentralized liquidity platform Meteora, revealed details of its market-making arrangements in its 2025 token holder annual report. Novora's findings indicate that 91% of the reviewed protocols generated traceable revenue, yet only 18% provided quarterly updates, and a mere 8% issued token holder reports. This suggests that while relevant data exists, it is rarely integrated into structured investor communication channels. The study encompassed decentralized exchanges, lending platforms, perpetual futures, Layer-1 and Layer-2 networks, cross-chain bridges, and centralized exchange tokens, with protocol valuations ranging from approximately $40 million to $45 billion.

BlackRock has identified a potential opportunity in short-term Eurozone bonds due to what it perceives as a mispricing of European Central Bank (ECB) rate hikes. According to Jin10, BlackRock executive Turner expressed that the ECB is unlikely to raise rates three times or even twice this year. This perspective aligns with the ECB policymakers' inclination to maintain rates unchanged at their meeting at the end of April. As a result, European government bonds experienced a slight uptick, and the currency market reduced bets on future rate hikes. Although the swap market still anticipates two rate hikes in 2026, the likelihood of a hike this month has decreased, boosting short-term bonds. The yield on two-year German bonds has fallen by about 10 basis points this week, potentially marking the largest weekly decline in a year. Turner believes short-term bonds present the greatest opportunity, while long-term bonds are less attractive due to "decreased government security."

OpenAI is actively advancing the construction of a comprehensive network defense ecosystem aimed at safeguarding individuals globally.
