#30年期美债收益率突破5% The marginal destructive power of the crypto market this week does not come from on-chain token structures nor from directional imbalances in the derivatives market, but from the synchronized displacement of external liquidity frameworks in the most unfavorable direction. The 10-year U.S. Treasury yield hit 4.67% on May 18, reaching a 16-month high; according to TradingEconomics data, the same day the 30-year Treasury yield climbed to 5.2%, the highest level in nearly 18 years; meanwhile, Brent crude oil temporarily broke through $112, directly triggering inflation premium re-pricing from the Iran scenario. BTC fell from $82,000 to a low of $76,270 on May 19 over four trading days, which is not due to active on-chain distribution, but a physical result of the external constraint conditions undergoing a qualitative shift, forcing the liquidation of highly leveraged structures. According to TradingEconomics data, as of May 20, the nominal yield of the 10-year U.S. Treasury remained around 4.67%, and the 10-year real yield on Treasury Inflation-Protected Securities (TIPS), as disclosed unilaterally by FRED, closed at 2.18% on May 19; the real interest rate is in a range that structurally suppresses non-interest-bearing assets. The Nasdaq closed at 22,017 points on May 20, with a daily increase of only 0.10%, providing no offsetting risk appetite support signals in the equity market. Its underlying constraint is: the probability of a rate hike in December 2026 priced by CME Federal Funds Rate futures, cited unilaterally by Phemex, has risen to 44%, while Polymarket unilaterally shows the probability of rate cuts within 2026 approaching zero. This means the core bullish narrative premise of the crypto market since the second half of 2024—the Fed rate cut cycle providing liquidity expansion—has been completely priced out. The contradiction in cross-asset pricing is: when BTC briefly touched $82,000 the previous week, the driving forces were the regulatory benefits from the CLARITY Act advancing in the Senate Banking Committee and a brief inflow of ETF funds; but when the 30-year Treasury broke through 5% and extended to 5.2% within the same week, any marginal premium from regulatory narratives could not hedge the discount rate pressure caused by rising actual interest rates. The chain reaction triggered by this is: BTC quickly retreated from the $82,000 local high, and after losing the $80,000 support, the speed of stop-loss triggers was significantly faster than the similar correction in April. $BTC
