Japan's central bank will maintain its policy rate at 1% on Friday after recently stepping in to support the yen. Overnight intervention involved buying yen and selling dollars, triggering the biggest one-day yen rally since January 2023 and pulling the currency back from a 40-year low.
The USD/JPY rate plunged from above 163 down to below 158 during the intervention, only to rebound partially to 160.175 in early Friday trades as the effect weakened. This quick reversal highlights how currency moves can unravel fast without ongoing central bank backing.
Market Dynamics and Policy Outlook
Rodrigo Catril, a senior FX strategist at National Australia Bank, noted that the timing was opportune amid a softer dollar and calmer risk sentiment. The Bank of Japan lifted its rate to 1% in June, the highest in 31 years, but is expected to hold rates steady this week while delivering a hawkish tone. Analysts anticipate another hike to 1.25% before year-end.
Adding to the pressure on Japan is the Federal Reserve’s recent hold on rates, marking its fifth consecutive pause. This has weakened the US dollar broadly, causing the US Dollar Index to drop 0.7% recently, on track for a 1.5% weekly decline. The shrinking interest rate gap between the Fed and BoJ complicates the yen carry trade, riskier if the yen strengthens too fast.
With the carry trade reliant on the rate difference, any rapid appreciation in yen could trigger swift unwinding of these positions, making Governor Kazuo Ueda’s tone during the meeting key to watch.
