Yen Slump Continues Amid BoJ Rate Hikes and Structural Headwinds

The Japanese Yen has seen a significant decline in value since the start of 2026, hitting multi-decade lows against the US Dollar. To counter this depreciation, the Japanese government deployed a record-breaking ¥11.73 trillion between late April and late May.

Despite the Bank of Japan's efforts to normalize monetary policy by lifting interest rates to 1.00% in June - the highest level since 1995 - the Yen has continued to underperform. The central bank maintained its hawkish stance in July, hinting at further rate hikes, but this has not provided sustained support for the currency.

The Yen's weakness is attributed to a combination of structural headwinds, including persistent interest rate differentials and Japan's heavy reliance on imported energy and commodities. As long as real interest rates remain low in Japan compared to other major economies, investors will continue to borrow cheaply in Yen to fund investments elsewhere.

Additionally, Japan's massive government debt and fiscal constraints have exacerbated the currency's depreciation. The country's debt-to-GDP ratio exceeds 200%, raising concerns over fiscal sustainability. Investors remain wary of additional deficit borrowing under Prime Minister Sanae Takaichi's spending plans.
