May 27th: According to data from Coinglass, Coinbase’s Bitcoin Premium Index has remained in negative territory for six consecutive days, standing at -0.1644% as of press time. Multi-day outflows from Bitcoin spot ETFs point to weak buying demand in the U.S. market.

May 27: Andreessen Horowitz (a16z) announced in a social media post that Ethereum remains the leader in the tokenized assets sector, backed by its early-mover edge in decentralized finance (DeFi) and strong institutional adoption. Here’s the current value of tokenized assets across major blockchains, per the firm’s data: - Ethereum: $15.7 billion - BNB Chain: $4 billion - Solana: $2.2 billion - Stellar: $1.7 billion - Liquid Network: $1.5 billion - XRP Ledger, ZKsync Era, Arbitrum: roughly $1 billion each a16z added that tokenized assets aren’t concentrated on one blockchain; instead, they’re spreading across multiple ecosystems based on factors like cost, liquidity, compliance rules, and market access connections, resulting in a multi-chain coexistence landscape.

May 27: Manuel Aráoz, co-founder of crypto security firm OpenZeppelin, posted on social media that he now believes the entire DeFi sector is insecure. He has begun advising friends and family to exit all their DeFi positions—even supposedly low-risk positions in blue-chip protocols like Aave, MakerDAO, and Compound. Aráoz pointed out the asymmetric dynamic between attackers and defenders in security incidents: “Auditors are far better at finding vulnerabilities, but smart contract security is too lopsided. Defenders have to fix every single bug, while attackers only need to find one to steal funds.” His comments reflect heightened market concern over DeFi security after a string of major incidents in recent months. Data shows April saw nearly $630 million hacked from DeFi protocols, making it the worst month since the $1.5 billion Bybit hack in February 2025. April’s exploits, including Drift’s $285 million loss and Kelp DAO’s $293 million loss, are widely tied to North Korean govern

May 27 — Minneapolis Federal Reserve President Neel Kashkari on Tuesday said the Fed must prioritize curbing surging inflation risks, but he’s not even close to predicting when the central bank will adjust interest rates. Kashkari also flagged that the “inflation shockwave” stemming from the Middle East conflict could linger, with those concerns now starting to show up in the bond market. When weighing the Middle East’s fallout on the U.S. economy, he noted inflation risks currently carry more weight than the chance of a weakening labor market — though he emphasized the Fed needs to watch both closely. Kashkari previously backed the Fed’s decision to hold rates steady in April, but was among officials who pushed back against the central bank’s dovish forward guidance. He argued the Fed should adopt “neutral guidance,” meaning future rate moves will hinge on upcoming economic data. “Since that dissent — several weeks ago now — I think most data points to inflation risks rising, not f

May 27 – Domestic cryptocurrency trading volume in South Korea has dropped to roughly one-tenth that of the Korea Composite Stock Price Index (KOSPI), according to South Korean outlet Digital Asset. The gap has widened sharply, driven primarily by a cryptocurrency market crash in October 2025 and the KOSPI’s ongoing string of record highs. Digital Asset analyzed trading activity across South Korea’s five major won-based crypto exchanges (Upbit, Bithumb, Coinone, Korbit, Gopax) and the KOSPI. As of May 26, the local won-denominated crypto market accounted for just 8% of KOSPI volume—down from a peak of 323% in December 2024. That 2024 crypto surge followed Donald Trump’s U.S. presidential election win and his pledge to make the U.S. the “digital asset capital,” pushing crypto trading to eclipse stock market volume. The crypto market’s slump began in the second half of 2025. By August that year, the ratio was nearly even at 99%. But October brought a sharp crypto crash tied to larg
