Core Viewpoint - The article discusses the recent fluctuations in the Hong Kong Interbank Offered Rate (Hibor) and its implications for the international monetary system, particularly in the context of the "de-dollarization" trend and the structural changes in global finance [2][25]. Group 1: Hibor Mechanism - Hibor reflects the average overnight borrowing rates among 20 major banks in Hong Kong and is influenced by the Hong Kong Monetary Authority's (HKMA) efforts to maintain a fixed exchange rate with the US dollar [3][5]. - The HKMA's actions to stabilize the currency involve adjusting liquidity in the banking system, which directly impacts Hibor rates [5][6]. Group 2: Hibor's Unexpected Low Levels - From May to August, Hibor experienced a significant drop from over 4% to near 0%, remaining at historical lows for three months before rising again [6][10]. - The prolonged low levels of Hibor were attributed to a decrease in the attractiveness of US dollar assets, which reduced the scale of carry and arbitrage trades that typically influence Hibor [6][15]. Group 3: International Monetary System Implications - The sustained low Hibor levels are seen as a reflection of the ongoing restructuring of the international monetary system, moving from a dollar-centric model to a more diversified framework [25][27]. - The article highlights two trends in this restructuring: fragmentation, indicating a return to local preferences in capital allocation, and diversification, where investors increasingly favor alternative assets like the Chinese yuan [27][15].
