March 23 — Global financial markets saw sharp volatility on Monday amid escalating Middle East tensions. Asian stocks tumbled across the board: Japan’s Nikkei 225 dropped 5%, South Korea’s KOSPI plunged 6%, Taiwan’s Weighted Index opened down more than 3%, and FTSE China A50 futures weakened in tandem. Safe-haven assets showed mixed performance: Spot gold briefly dipped below $4,370 an ounce, hitting a fresh low since early January, while spot silver tumbled more than 4%. Energy prices, meanwhile, gained ground, with oil prices extending their rise. In currency markets, the South Korean won dropped to a fresh 2009 low against the U.S. dollar, signaling accelerating capital flows into safe-haven assets. Market analysts note that geopolitical risk spillover is triggering a global selloff in risk assets and liquidity tightening, with short-term volatility likely to intensify further.

On March 23, Bitcoin’s mining difficulty dropped by approximately 7.76% to 133.79T—marking the second-largest negative adjustment of 2026 so far. The network’s current hashrate has fallen to roughly 903–948 EH/s, a significant drop from its 2025 peak. Analysts note that with bitcoin prices below production costs and mining revenues under pressure, many miners are shifting their infrastructure to AI and high-performance computing (HPC) operations, driving structural transformation in the industry. Mining firms such as Core Scientific and Bitdeer have accelerated these shifts, which could impact the Bitcoin network’s long-term security and hashrate distribution.
