Yen Breaks 160 Threshold Amid Fed Hike Expectations
The Japanese yen's value has breached the psychologically important level of 160 against the US dollar. This break is significant because it marks the first time the currency has crossed this threshold since the Bank of Japan (BoJ) intervened in late July to defend its value.
State Street's currency team describes 160 as a 'political line in the sand,' indicating that another rapid move through this level could prompt officials to intervene again. The Ministry of Finance typically responds to such situations with jawboning, rate-checking, and intervention.
The yen has been strengthening over the past month, gaining 2.04% against the US dollar. However, its overall trend remains bearish, having fallen 8.93% in the past year. This decline is largely due to the BoJ's continued efforts to normalize interest rates, which makes borrowing in yen more expensive and attracts investors to higher-yielding assets abroad.
The recent break of 160 was driven by Federal Reserve Chair Kevin Warsh's speech at Jackson Hole, where he emphasized concerns about inflation and hinted at a September rate hike. This shifted market expectations, with the dollar index rising 0.4% to 99.57 and USD/JPY climbing 0.42%. Meanwhile, other major currencies fell against the greenback.
Analysts argue that intervention can only provide temporary relief, as the fundamental trend of interest rate differentials remains in place. The carry trade, which involves borrowing in low-yielding yen to invest in higher-yielding assets abroad, is still under pressure due to the steep front-end yield curve and stable long-end yields.
Given this context, strategists recommend buying dips towards 157-158, where the last intervention's gains have already been surrendered. The asymmetry in market dynamics above and below 160 makes chasing USD/JPY higher from here less attractive.
