On Tuesday, the USD/JPY pair retreated to the 155.00 mark, influenced by a shift towards risk aversion in the markets and swirling rumours that the Bank of Japan (BoJ) might scale back its bond-buying program, bolstering the Japanese Yen (JPY) and exerting downward pressure on the USD/JPY. A cutback in bond purchases is expected to exert upward pressure on Japanese bond yields, which have a strong correlation with the JPY.
