高盛：黄金波动性大幅走高，央行购金力度将暂时放缓

Core Viewpoint - The dominant variable in the gold market is shifting from "buy or not" to "how much volatility" as Goldman Sachs indicates that increased demand for gold call options is driving price volatility, temporarily suppressing central bank gold purchases, which is expected to be a short-term phenomenon [1][4]. Group 1: Volatility and Options Demand - Goldman Sachs links the recent increase in gold price volatility to diversified demand from the private sector, particularly through gold call options [2][6]. - The report highlights that the open interest in call options for the largest gold ETF, GLD, is at record levels, serving as a key indicator for rising volatility [2]. - As gold prices rise, option sellers are forced to buy gold to hedge, amplifying price increases; however, even minor pullbacks can lead to a shift from "buying on the rise" to "selling on the dip," potentially triggering stop-loss orders and further losses [2][7]. Group 2: Central Bank Demand - Central bank gold purchasing is experiencing a temporary slowdown, with a forecast of 22 tons for December 2025, significantly below the 12-month average of 52 tons [4][6]. - Goldman Sachs views this slowdown as a temporary phenomenon rather than a trend reversal, based on communication with central banks and changes in risk perception following geopolitical events [4][6]. - Central banks still consider gold a hedge against geopolitical and financial risks but prefer to wait for price stability before increasing purchases [4]. Group 3: Scenarios for Gold Price Movement - Goldman Sachs outlines two scenarios regarding the interplay of volatility, central bank demand, and gold price paths [5][6]. - The baseline scenario assumes no additional diversification from the private sector, leading to a decrease in volatility and a subsequent acceleration in central bank gold purchases, with gold prices expected to rise to $5,400 per ounce by the end of 2026 [6]. - The bullish scenario posits that increased diversification demand from the private sector, driven by perceived fiscal risks in some Western economies, could lead to sustained high volatility and significant upward price risks [6]. Group 4: Tactical Insights - On a tactical level, Goldman Sachs warns that even mild catalysts could trigger significant price pullbacks, estimating a downside boundary around $4,700 per ounce [7]. - Following the "washout" of call option demand in late January, the demand has rebuilt to record levels, indicating that typical factors causing limited pullbacks could lead to extraordinary declines in gold prices [7]. - Despite the potential for short-term pullbacks, there remains a latent demand for accumulation on dips, supporting a bullish medium-term outlook for gold prices [7].
