USD/JPY Intervention Fails to Alter Fundamental Backdrop

The intervention in USD/JPY by the US and Japan has sparked debate on its effectiveness. Despite a sharp reversal, the fundamental forces driving higher haven demand remain unchanged.

Japan's loose monetary policy continues to weigh on the yen, with interest rates below those elsewhere and real rates still negative. The Bank of Japan passed up an opportunity to signal further normalization, instead producing a cautious performance.

The government debt auction reinforced the need for higher yields, with demand softening and the bid-to-cover ratio slipping. Global markets' buoyancy encourages investors to borrow in cheap funding currencies and invest elsewhere, maintaining structural forces against the yen.
