Yen Intervention Triggers Market Uncertainty

The Japanese yen is at a critical juncture after a record-setting intervention by the US and Japan, which has led to significant losses for traders. The USD/JPY pair had reached a 40-year low of ¥164 before the intervention on July 30. However, despite the coordinated action, market participants are still on edge as both countries have said they are prepared to intervene again if needed.

The US Treasury financed its share of the intervention by selling euros from reserves to buy yen, which is a rare move considering Japan's typical financing method involves selling Treasury holdings. FP Markets Chief Market Analyst Aaron Hill commented that 'To prevent the yen from weakening further, intervention alone is unlikely to be sufficient.'

Hill also stated that the Bank of Japan would need to increase its policy rate a few more times and provide an exogenous catalyst for repatriation to keep the JPY structurally bid. Without this, USD/JPY dip-buyers could emerge and target pre-intervention levels in the not-so-distant future.
