USD/JPY moved above 162 on Forex Factory, breaking past its 2024 highs and returning to levels not seen since the 1980s. Traders are now weighing whether the BoJ acts in the coming days or waits for a better window.
The move puts the pair back near the zone where the Bank of Japan sold just over $70bn in late April and early May, when rates were a little above 160. Japan’s officials have tied the weak yen to higher import costs and pressure on living costs, so the next move is being watched as a policy signal as much as a market one.
BoJ faces a narrow window
The BoJ has usually stepped in during clustered bursts of two to three days, and those bursts have often come when trading is thin around holidays. Friday’s US July 4th holiday is one possible window, and 16–17 July is another if policymakers want to move before Marine Day on 20 July.
Kevin Warsh and the June US jobs report sit in the background as possible dollar-positive event risks. That gives the BoJ a reason to wait, even though intervention is widely expected again. The market still has to balance that expectation against the reality that the yen has already moved far enough to force officials to think about action.
FX options market pricing
The FX options market gives a 37% probability to USD/JPY touching 165 by the end of July. If the BoJ holds off and US data plus Fedspeak stay hawkish, the pair could be trading around 164–165 by then. That leaves intervention timing running against market momentum instead of ahead of it.
The speculative position is short yen, but not as extreme as during the successful intervention campaign of summer 2024. That makes the current setup less stretched than the last time the BoJ forced a reversal, even though the pair is again pressing a level that has drawn official attention before.
Japan reserves and IMF rules
Japan has close to $1.1trn in FX reserves, down from a low point this decade of around $1.07trn after the May FX reserve data showed BoJ holdings of securities falling $75bn. That drop presumably reflects sales of US Treasuries, and it shows the scale of the balance sheet the authorities would be drawing on if they step in again.
The IMF counts an intervention instance as lasting no longer than three business days, and more than three instances over a six-month period could push Japan’s currency regime from free floating to floating. That puts a practical ceiling on how often the BoJ can keep leaning on the market, especially if it wants to avoid draining reserves below the $800-900bn range that looks like a floor.
A no-show this week would strengthen the case for waiting until 16–17 July. Whether the Bank of Japan acts on Friday, waits for mid-July, or lets USD/JPY run higher first is the part traders still have to price.
