香港经济受联系汇率制影响，美元信用下降超预期

Core Viewpoint - Hong Kong's interest rates are declining despite the currency peg to the US dollar, leading to a widening gap between Hong Kong's rates and US rates, which raises uncertainties for the local economy [2][6]. Group 1: Interest Rate Dynamics - The Hong Kong Interbank Offered Rate (HIBOR) for one month is currently around 0.5%, the lowest level in approximately three years, while the US Secured Overnight Financing Rate (SOFR) is about 4.3% [2]. - The interest rate gap has expanded to its largest scale since SOFR became public in 2018, with a drop of about 3% in HIBOR over the past month [2][5]. Group 2: Market Reactions and Implications - Major real estate companies in Hong Kong, such as Henderson Land Development and Sun Hung Kai Properties, have seen their stock prices rise by approximately 20% compared to late April, prior to the HKMA's intervention [6]. - The HKMA's intervention in May, which involved selling and buying US dollars totaling HKD 129.4 billion, has increased market liquidity and contributed to the decline in interest rates [3]. Group 3: Economic Context and Future Outlook - The current low interest rates are expected to stimulate real estate transactions, but there are concerns that these low rates may not last long due to potential interventions by the HKMA if the HKD approaches its lower limit of 7.85 against the USD [6]. - The ongoing trend of de-dollarization and reduced activity in arbitrage trading has contributed to the sustained low interest rates, despite the typical market behavior of borrowing in low-rate HKD to invest in higher-rate USD [5].
