Japanese Yen Weakens Against US Dollar After BoJ Rate Hike
Confirmed
In Short: The Japanese yen weakened against the US dollar on Monday after the Bank of Japan raised its short-term interest rate target.

The Japanese yen weakened against the US dollar on Monday after the Bank of Japan (BoJ) raised its short-term interest-rate target to 1.25% from 1.00%, a move widely anticipated by financial markets.
The USD/JPY exchange rate eased back below 157.00 in Asia, reflecting modest strength in the Japanese yen amid concerns over potential intervention risks following Friday's BoJ rate decision.
The BoJ's decision to raise interest rates was seen as a response to intensifying inflationary pressures, with BoJ board member Hajime Takata advocating for a more nimble approach to interest-rate increases.
Despite the BoJ's rate hike, the US Dollar strengthened after the Federal Reserve raised interest rates and issued a hawkish outlook, pushing the currency to seven-week highs.
The USD/JPY pair faced downward pressure as the New Zealand Dollar (NZD) weakened following signals that future Reserve Bank of New Zealand (RBNZ) rate hikes would be gradual.
The so-called rate differential, or how rates in New Zealand are or are expected to be compared to the ones set by the US Federal Reserve, can also play a key role in moving the NZD/USD pair.
The Mexican Peso appreciated against the US Dollar on Thursday, with the latter weakening amid a dovish tilt by Fed Governor Waller and speculation about an FX market intervention to boost the Japanese Yen.
Waller supports holding rates unchanged if the disinflation process evolves, but warned that a rate hike is possible if a red-hot US CPI report is released next week.
The Bank of Japan's rate hike and the Federal Reserve's hawkish stance have raised questions about the effectiveness of aggressive rate hikes in reversing currency trends.
Once investors lose confidence in a currency, even aggressive rate hikes may not be enough to reverse the trend.
A historical example cited by analysts is Sweden's Riksbank, which raised its policy rate to 500% in the early 1990s to defend the krona, only to abandon its exchange-rate peg shortly after.
What this adds
The Japanese yen's rise was driven largely by expectations that the Bank of Japan may increase interest rates sooner or more aggressively than markets had anticipated.
The US Dollar's strength is attributed to the Federal Reserve's recent hawkish stance, which has pushed the currency to seven-week highs.
