他举例分析，2024年底巴西与美国的利差降至5%，为近20年来第二低，仅高于2021年至2022年疫情期 间的水平。数据显示，这两个时期雷亚尔在实际和名义上都经历了显著贬值，尽管当时巴西外部经济环 境相对稳定。 他引用Santander银行2023年12月发布的一份特别报告分析称，巴西汇率与利差的关系并非传统利率平价 理论所描述的线性模式，而是呈"微笑曲线"特征： ——当利差处于"正常"水平（约6%-10%）时，汇率反应不大； 新华财经圣保罗8月11日电（记者杨家和）巴西Banco Master银行首席经济学家、瓦加斯基金会教授保 罗·加拉（Paulo Gala）近日撰文指出，当前雷亚尔再次出现对美元贬值趋势，这一现象在雷亚尔高利率 背景下显得颇为反常。他认为，影响雷亚尔汇率的关键在于巴西与美国的利差水平，而非巴西基准利 率；而利差的扩大或将导致雷亚尔贬值。 ——当利差降至6%以下时，雷亚尔会出现非线性的大幅贬值； ——当利差过高（10%以上）时，也可能因国家风险飙升而引发贬值。 2024年的情况与此相符。当时由于美国降息速度慢于巴西，利差缩小至约5%，在巴西基准利率为 10.5%、美联储利率为5.5%的背景 ...

1. Report Industry Investment Rating No information about the industry investment rating is provided in the content. 2. Core Viewpoints of the Report - The linkage between exchange rates and interest rates is the result of policy - goal trade - offs under the "Impossible Trinity". When the domestic fundamentals are resilient, policies block the interest - rate parity transmission through foreign - exchange management tools, and exchange rates and interest rates mainly reflect internal equilibrium. When fundamentals are under pressure and there are external shocks, policies allow exchange - rate flexibility, and the interest - rate parity mechanism dominates cross - border capital flows [4]. - The future scope for interest - rate cuts depends not only on the narrowing of the China - US interest - rate spread but also on whether broad - credit policies can stimulate domestic demand and whether trade transformation can strengthen exchange - rate resilience [4][11]. - The core contradiction in the current linkage between interest rates and exchange rates lies in the dynamic balance between external constraints and internal policy space. Policy frameworks need to reshape the transmission path of interest - rate spreads and exchange - rate differentials through tool innovation and expectation management [101]. 3. Summary According to Relevant Catalogs 3.1 Interest and Exchange Rate Correlation - Interest rates and exchange rates represent the internal and external prices of currencies respectively, with a high correlation. The exchange rate has a stronger correlation with long - term interest rates that reflect fundamental expectations and with the interest - rate spread that reflects China - US relative changes [7][19]. - The relationship between exchange rates and interest rates is complex, being affected by common factors and possibly being causal to each other. Under the "Impossible Trinity", policies need to make dynamic trade - offs among exchange - rate stability, capital flow, and monetary - policy independence [7]. 3.2 Linkage between Exchange Rates and Interest Rates under the "Impossible Trinity" 3.2.1 Stages Driven by Common Factors - When external shocks occur and domestic fundamentals are strong, policies prioritize "exchange - rate stability" and "monetary - policy independence" while weakening capital free flow. The ability of domestic fundamentals to "absorb" shocks determines whether exchange rates and interest rates are affected by external factors [8][32]. - Examples include the 2018 - 2019 China - US trade friction period and the 2020 - 2021 global public - health event period. In these periods, China maintained monetary - policy independence, and the correlation between interest - rate spreads and exchange rates decreased [40][44]. 3.2.2 Stages of Mutual Causality - When domestic and overseas monetary - policy cycles diverge and domestic fundamentals are under pressure, policies tolerate exchange - rate fluctuations to enhance monetary - policy autonomy. Capital flows affect exchange rates through the interest - rate parity mechanism, forming a self - reinforcing cycle [51]. - Examples are the period from August 2015 to 2016 and the 2022 - 2024 period. In these periods, the two - way causal relationship between interest - rate spreads and exchange rates was significant, and the explanatory power of the interest - rate parity theory increased [52][56]. 3.3 Application of Exchange - Rate and Interest - Rate Linkage in Bond - Market Investment 3.3.1 Arbitrage Calculation under the Covered Interest - Rate Parity (CIP) Theory - International investors calculate the comprehensive return of the China - US interest - rate spread and hedging costs when allocating RMB bonds. The balance between hedging costs and interest - rate spreads drives short - term bond - allocation preferences [9]. - The CIP theory provides a pricing benchmark for cross - border capital flows. When there are differences in comprehensive returns between domestic and foreign investments, investors will engage in arbitrage until the returns are equal [68][69]. 3.3.2 Impact of Central - Bank Exchange - Rate Stabilization Operations on Foreign Bond Purchases - Central - bank exchange - rate stabilization tools can reset arbitrage costs. For example, the counter - cyclical factor can reduce the forward - premium rate, while offshore - liquidity regulation can increase arbitrage friction costs, and macro - prudential tools can have a structural constraint on capital flows [86][91][92]. - Different types of foreign investors have different responses to central - bank policies. Short - term trading funds are more sensitive to arbitrage - friction costs, while long - term allocation funds may turn to holding medium - and long - term interest - rate bonds when the costs exceed a certain threshold [97]. 3.4 Future Outlook on the Linkage between Interest Rates and Exchange Rates - The core contradiction in the current linkage between interest rates and exchange rates is the dynamic balance between external constraints and internal policy space. The Fed's policy - turning rhythm and China's growth - stabilization needs are important factors influencing the linkage between interest - rate spreads and exchange rates [101][102]. - Policy frameworks need to reshape the transmission path of interest - rate spreads and exchange - rate differentials through tool innovation and expectation management to achieve a dynamic balance between "self - orientation" and "internal - external equilibrium" [101].

Core Viewpoint - The People's Bank of China (PBOC) has announced a reduction in the reserve requirement ratio (RRR) by 0.5 percentage points and a decrease in policy interest rates by 0.1 percentage points to implement a more accommodative monetary policy and enhance macroeconomic regulation [1][8] Group 1: Monetary Policy Tools - The PBOC's decision to lower the RRR and interest rates is aimed at releasing market liquidity and stimulating investment and consumption, especially in the face of various internal and external pressures on economic growth [1][3] - The PBOC emphasizes a cautious approach to using these tools, balancing the need for liquidity with the potential risks associated with a complex economic environment [1][2] Group 2: Factors Influencing Timing - Domestic economic indicators, such as a manufacturing PMI below 50% and low CPI, suggest a need for monetary easing to boost market confidence and stimulate demand [4][8] - The current liquidity conditions in the financial market, including rising interbank rates, indicate a need for increased liquidity supply from the PBOC [5][9] - The pressure on banks' net interest margins has eased, providing a more favorable environment for the PBOC to implement rate cuts [6][10] Group 3: External Influences - The global liquidity environment, particularly the policies of the Federal Reserve, plays a significant role in the PBOC's decision-making regarding rate cuts [7][12] - Expectations of a potential rate cut by the Federal Reserve create a "time window" for the PBOC to adjust its policies without immediate adverse effects on the currency [12]

Group 1 - Central bank policies are a primary driver of foreign exchange markets, influencing currency supply and demand, market expectations, and economic fundamentals, which in turn affect exchange rate fluctuations [1] - Interest rate adjustments directly impact borrowing costs, influencing capital flows and currency values; for instance, aggressive rate hikes by the Federal Reserve in 2022 led to a nearly 20% surge in the US dollar index, reaching a 20-year high [4][24] - Quantitative easing (QE) increases money supply and can lead to currency depreciation, as seen when the Federal Reserve's unlimited QE during the pandemic caused a 12% drop in the dollar index [7][6] Group 2 - Central banks can intervene directly in the foreign exchange market by buying or selling currencies to influence exchange rates; for example, Japan's Ministry of Finance warned about potential intervention to stabilize the yen [11][9] - Forward guidance from central banks can shape market expectations regarding future policy directions, with hawkish signals typically strengthening the currency and dovish signals weakening it [12][13] Group 3 - The transmission of central bank policies to the foreign exchange market occurs through various channels, including interest rate parity, capital flows, inflation expectations, and risk sentiment [16][22] - The Federal Reserve's dual mandate focuses on employment and inflation, making the US dollar a global safe-haven currency, while the European Central Bank's policies are primarily aimed at inflation control, impacting the euro's value [24][25] Group 4 - Recent policy shifts, such as the Federal Reserve's transition to aggressive rate hikes from late 2021, have led to significant market reactions, including a rise in the dollar index and a peak exchange rate against the yen [24][1] - The Bank of Japan's unexpected adjustment of its yield curve control policy in December 2022 resulted in a 4% appreciation of the yen against the dollar, breaking a long-term depreciation trend [26][2] Group 5 - Future challenges for central banks include the rise of digital currencies and geopolitical factors that may influence monetary policy and currency dynamics, such as the trend of "de-dollarization" among various nations [32][34] - The interconnectedness of markets necessitates that traders consider policy analysis alongside technical factors and liquidity management to navigate extreme market conditions effectively [38][37]

Group 1: Federal Reserve's Monetary Policy - The Federal Reserve maintained the federal funds rate target range at 4.25%-4.5% during the March meeting, with a slight reduction in the number of members expecting rate cuts this year, indicating a decrease in overall rate cut expectations [3][4] - The Fed's updated economic forecasts show a significant downgrade in the U.S. economic growth rate for 2025 from 2.1% to 1.7%, alongside an increase in core PCE inflation expectations from 2.5% to 2.8% [3][4] - The Fed announced a slowdown in balance sheet reduction starting in April, which is expected to have a positive effect on the economy and stock market, akin to a partial rate cut [2][5] Group 2: Domestic Monetary Policy in China - The People's Bank of China (PBOC) announced that the one-year Loan Prime Rate (LPR) remains unchanged at 3.1% and the five-year LPR at 3.6%, marking the fifth consecutive month of stability [2][7] - There are expectations for a potential interest rate cut in the second quarter of this year, driven by the need to support economic growth amid external uncertainties [7][10] - The recent stabilization of the RMB against the backdrop of a declining U.S. dollar index may create favorable conditions for the PBOC to consider rate cuts [7][8] Group 3: Economic Outlook and Risks - The U.S. economy is showing signs of cooling, with increasing downward pressure that may prompt the Fed to consider rate cuts in the second half of the year, particularly around June or July [6][10] - The Chinese economy is expected to face challenges in the second quarter, with potential declines in exports to the U.S., which may necessitate monetary easing to bolster domestic demand [10]
