Bank of America stated in a recent report that foreign exchange market interventions by major developed countries remain rare but highly impactful policy tools, with Japan and Switzerland identified as the most active participants among G10 nations. The analysis comes as speculation grows around potential Japanese intervention following the USD-JPY exchange rate climbing above 162 yen to reach its highest level in approximately 40 years. According to Yahoo Finance, the bank highlighted that authorities typically intervene only during periods of excessive volatility, severe currency distortion, or widespread financial stress, often combining direct market actions with policy guidelines and official statements to influence investor expectations.
Japan Maintains Repeated Yen Defense Interventions Since 2022
BofA stated that Japanese authorities have repeatedly intervened in the market since 2022 to defend the yen, including estimated interventions that occurred this year, as concerns grew over import prices and financial stability due to sharp fluctuations in the dollar-yen exchange rate. The bank noted that these intervention efforts reflect ongoing official concerns about currency volatility impacts on the domestic economy.
US Treasury Determines Exchange Rate Policy With Rare Intervention Approach
The US exchange rate policy is determined by the Treasury Department, with the Federal Reserve Bank of New York performing all actual operations on behalf of the government. BofA noted that US foreign exchange intervention is very rare because the US government primarily prefers exchange rates to be determined by the market.
Switzerland Relies on FX Intervention as Monetary Policy Component
Swiss authorities were also assessed as relying on foreign exchange intervention as part of their monetary policy framework. The bank identified Switzerland alongside Japan as among the most active G10 countries in utilizing this policy tool.
Coordinated Interventions Supported by Economic Policy Show Greatest Effectiveness
BofA stated that coordinated interventions supported by broader economic policies tend to have the greatest effect. The bank analyzed that such intervention operations do not remain confined to the foreign exchange market alone - when large foreign exchange reserve portfolios are adjusted, this changes central bank balance sheets and can affect domestic liquidity and held assets, as well as US Treasury rates and swap spreads. However, BofA emphasized that foreign exchange market intervention alone rarely changes the long-term direction of a currency.
