Citi(US:C) 凤凰网财经·2025-09-13 14:21Core Viewpoint - Citi believes that the $550 billion investment fund involved in the US-Japan tariff agreement may lead to a form of a bilateral "mini Mar-a-Lago agreement," which could weaken the dollar and strengthen the yen [1][2]. Group 1: Investment Fund and Currency Impact - Japan's planned $550 billion investment in the US is likely to heavily rely on its $1.3 trillion foreign exchange reserves [1]. - The investment fund established under the tariff agreement is expected to invest in US assets with maturities of 10-20 years, contrasting with Japan's holdings of US Treasury bonds, which have an estimated duration of 3-5 years [1]. - If Japan sells short-term US Treasuries to finance this long-term investment fund, it may lead to an increase in US long-term bond yields [1]. Group 2: Bilateral Coordination and Currency Trends - The high-level bilateral coordination aimed at addressing potential market volatility is the basis for what Citi refers to as the "mini Mar-a-Lago agreement" [2]. - There is a belief that the trend of a weaker dollar and a stronger yen will persist from a monetary policy perspective, despite the recent poor performance of the yen due to political uncertainties and tariff issues affecting the Bank of Japan's rate hike path [2].
