BOJ Rate Hike Fails to Stabilize Yen Amid Intervention Fears

The Bank of Japan has raised its policy rate to the highest level in 31 years, but the yen remains unstable. This move has prompted Japanese currency authorities to prepare for market intervention through a rate check.

According to reports from the Nihon Keizai Shimbun and other outlets, the Japanese government and the BOJ conducted a surprise rate check around midnight on the 19th, Tokyo time. A rate check is generally seen as the step immediately preceding intervention.

The markets responded quickly to the news, with the yen-dollar rate falling back to the 156 range after rising to the 158 range per dollar following the BOJ's decision to raise rates.

Investors are now closely watching for any further intervention, particularly during Japan's holiday period running through the 23rd. This is because domestic trading by investors declines and foreign exchange liquidity can thin out, which could widen swings in the exchange rate and accelerate the yen's decline.
