央行，连续两个大动作来了

Group 1 - The central bank increased its gold reserves to 73.96 million ounces by the end of July, up from 73.90 million ounces at the end of June, indicating a purchase of 60,000 ounces of gold in July [1] - The foreign exchange reserves decreased by $25.2 billion at the end of June, attributed to the rise in the US dollar index, with the central bank taking advantage of this for short-term arbitrage [1] - The central bank's strategy of increasing gold reserves while decreasing foreign exchange reserves aligns with the goal of preserving and appreciating foreign assets, primarily as a hedge against potential depreciation of the US dollar [1] Group 2 - To maintain liquidity in the banking system, the central bank will conduct a 700 billion yuan reverse repurchase operation with a three-month term, which is not directly related to the stock market's performance [3] - The 700 billion yuan reverse repurchase operation is intended to offset the maturity of 4 trillion yuan in three-month and 5 trillion yuan in six-month reverse repos, indicating a tightening liquidity situation despite the operation [3] - The central bank's ongoing policy aims to keep market liquidity ample, suggesting that further operations may occur in the future [4]
