Dollar Breaks ¥163 as Japan’s $71.9 Billion Defense Falters

The yen has been under sustained pressure from the wide gap between US and Japanese interest rates, capital outflows and Japan’s reliance on costly imports. The currency’s slide to levels unseen since 1986 matters because it raises household and corporate expenses while testing the ability of Japan’s Ministry of Finance and the Bank of Japan to stabilize markets without undermining an already fragile economy.

The dollar has now climbed above ¥163, its strongest level against the Japanese currency in about 40 years. Japanese authorities have previously spent roughly $71.9 billion supporting the yen, but the intervention failed to reverse its broader decline. Traders are turning their attention to ¥165 as the next potential line of defense, while analysts warn that Japan has few policy options left as direct intervention offers limited durability and the scope for aggressive interest-rate increases remains constrained.
