Core Viewpoint - Goldman Sachs analysts indicate that the US dollar is currently overvalued by approximately 16%, driven by global capital chasing the superior return prospects of the US. As the US return advantage diminishes, the overvaluation of the dollar may gradually correct, suggesting potential mid-term adjustment pressure on dollar-denominated assets [1][4]. Valuation Models - Goldman Sachs employs two primary models, GSDEER and GSFEER, to assess dollar valuation, revealing that the actual trade-weighted dollar index is about 16% above its fair value [2]. - The GSDEER model, an enhanced version of purchasing power parity (PPP), shows that the dollar is overvalued by approximately 15% against the trade-weighted index, particularly against the yen, yuan, euro, and Canadian dollar, with the most significant mismatches against the yen and yuan [2]. - The GSFEER model, which focuses on economic imbalances, indicates that the dollar is overvalued by about 17%, with over 16% attributed to the deviation of the US current account deficit from its "standard level" [2]. Current Account Deficit and Dollar Adjustment - The degree of dollar overvaluation is highly dependent on the assumptions regarding the current account "standard level." Currently, the US actual current account deficit is around 4% [3]. - If the current account deficit narrows to 2.6%, it could correspond to a 16.5% adjustment in the dollar; further reduction to 2% (close to the IMF 2023 standard) could lead to a 22% depreciation; and a reduction to 1% may require a 31% depreciation [3]. - The research emphasizes that due to the relatively closed nature of the US economy (with exports accounting for about 11% of GDP), a more significant exchange rate adjustment is necessary to address a similar-sized current account gap compared to more open economies [3]. Historical Context and Future Outlook - Historical examples show that currencies can rapidly adjust to fair value when significant macroeconomic changes occur, as seen with the British pound post-Brexit and the euro during gas price shocks [3]. - Goldman Sachs suggests that the overvaluation of the dollar has been a persistent phenomenon in recent years, but as the relative return advantage of the US diminishes and potential policy shifts occur, the market may witness a gradual adjustment of the dollar to a more reasonable valuation level [4].
