Core Viewpoint - The current gold price uptrend, which began in 2019, has lasted for six years with a cumulative increase of 219%, raising market concerns about future price movements [1][2]. Group 1: Historical Context - Gold has experienced three major uptrends since 1968, with the first from 1970 to 1980 (highest increase of 2323%) and the second from 2001 to 2012 (highest increase of 599%) [2]. - The current uptrend, starting in 2019, has shown a cumulative increase of 219% over six years, which is shorter in duration compared to previous cycles [3]. Group 2: Monetary Attributes - The dollar has depreciated nearly 100% against gold since 1970, with a 35% decline in 2025 alone, driven by increasing fiscal deficits and monetary supply [9]. - The relationship between the dollar index and gold prices has been negative, with the dollar index dropping nearly 10 percentage points since 2025, benefiting gold prices [9]. - Economic and political uncertainties have increased the U.S. economic policy uncertainty index significantly since early 2025, impacting the dollar's credibility [11]. Group 3: Commodity Attributes - Central bank gold purchases have surged from 255 tons in 2020 to 1089 tons in 2024, with an average annual growth rate of 44%, increasing their share of total demand from 5% to 22% [15]. - Jewelry demand has decreased from approximately 50% before 2020 to 32% in the first three quarters of 2025, indicating a shift in demand dynamics [15]. - Global gold reserves have increased significantly, with European countries showing high reserve ratios, contributing to upward pressure on gold prices [15]. Group 4: Financial Attributes - The traditional negative correlation between real interest rates and gold prices has weakened since 2021, as high inflation distorts real interest rates and enhances gold's anti-inflation properties [22]. - Real interest rates have increased by 213% during the current cycle, contrasting with previous cycles where they remained near zero or negative [38]. - The ratio of the S&P 500 to gold prices is approaching historical averages, suggesting that gold may be fully valued relative to equities, yet still has room for growth compared to previous cycles [22]. Group 5: Key Variables for Future Price Movements - The report identifies three critical variables that will influence future gold prices: geopolitical risks, growth in gold reserves, and changes in real interest rates [25][32]. - The geopolitical risk index has risen by 72% since 2019, reflecting heightened global tensions due to events like the COVID-19 pandemic and the Russia-Ukraine conflict [28][31]. - Global gold reserves have increased by 167% during the current cycle, a significant rise compared to previous periods, indicating a strategic shift among central banks [35].
