Yen Intervention Fades, Bitcoin Caught in Middle

A joint intervention by Japan and the US helped stabilize the yen in early August. However, that relief was short-lived as USD/JPY reclaimed its previous level of 159, reversing much of the intervention-driven rally.

The rescue effort cost nearly $88 billion, with Japan spending around $53 billion on July 30-31 and a second round adding roughly $34 billion. The US also joined in, selling euros for yen through the New York Fed.

Despite the initial success of the intervention, analysts believe that Japanese investors continued to buy foreign bonds at a strong pace in July, suggesting limited appetite to shift capital back to Japan.
