PANews reported on April 29 that according to The Block, on April 25, the 30-day Pearson correlation coefficient between Bitcoin and gold reached 0.54, close to the annual high of 0.73. Previously, the two had "decoupled" in February, and the correlation coefficient plummeted from 0.73 to -0.67 in three weeks. At the beginning of February, the price of Bitcoin was about $102,000 and gold was $2,800 per ounce; by the end of February, Bitcoin fell to $84,000 and gold rose to $2,850, and the price difference caused the correlation coefficient to plummet. Since then, the correlation coefficient has rebounded sharply to 0.52. This "recoupling" may be caused by macroeconomic uncertainty caused by the imposition of tariffs by the United States. From a historical perspective, "recoupling" can be attributed to cyclical fluctuations. Since 2020, the correlation coefficient has been close to or below -0.50 18 times, of which 17 times rebounded within a week, with the only exception being December 2022. Historically, whenever the coefficient falls to extreme levels of -0.50 or lower, the correlation coefficient between Bitcoin and gold will subsequently experience a strong "recoupling", usually rising back to 0.8 or higher, before a new round of "decoupling" cycle begins.
