Core Insights - The significant outperformance of the WisdomTree Japan Hedged Equity ETF (DXJ) over non-hedged funds is attributed to both currency depreciation and interest rate differentials [1][10]. Interest Rate Dynamics - The returns from DXJ and iShares Currency Hedged MSCI Japan ETF (HEWJ) have been positively impacted by higher carry due to interest rate increases in 2021 and 2022 [2]. - The interest rate differential between the US and Japan has been a critical factor, with US rates significantly higher than Japan's negative rates [5][10]. Currency Forward Contracts - Both DXJ and HEWJ utilize 1-month JPY/USD FX Forward contracts to hedge against currency fluctuations, which helps protect their USD value even if the JPY depreciates [4][6]. - The forward premium in JPY is driven by the interest rate differential, which has implications for the returns of hedged funds [5][10]. Performance Comparison - A table comparing US and Japan's 3-month interest rates shows a consistent interest rate advantage for US rates over Japan from 2018 to 2023, with the differential peaking at 5.79% in October 2023 [7][8]. - The performance difference between HEWJ and EWJ (non-hedged) closely aligns with the interest rate differential, particularly after 2022 when HEWJ's returns exceeded the 3-month rate by 2% [10][12]. Hedging Implications - Hedging is viewed as a strategic bet on the strength of the USD against the JPY, with the absence of hedging representing an implicit risk exposure [14]. - The analysis suggests that hedging strategies can yield different outcomes based on the interest rate environment and currency movements, as seen in the comparison of hedged versus unhedged funds [15][21].
