USD/JPY forecast: Intervention effective only in short-term.We saw the USD/JPY dip again this morning, but it has since bounced back after again finding good support at just below the 156.00 level. Alongside what looked like fairly sizeable dollar-selling from the Bank of Japan yesterday, you also had a decent push higher in equities, which only added to the softer tone in the dollar more broadly, while the dip in oil prices yesterday also clearly helped.
