USD/JPY moved back above 160.50 on Friday after the Bank of Japan left its policy rate unchanged at 1%. The yen had strengthened sharply a day earlier, briefly reaching about 157.80 per dollar, as traders reacted to signs of official currency intervention. Much of that advance faded once the central bank avoided another immediate increase.
In this article, experts at Sylverix examine whether intervention risk can stop USD/JPY from returning to 162.00 or whether tighter Japanese policy may support the yen during future declines.
The BOJ Keeps Rates at 1%
The Bank of Japan held its short-term policy rate at 1%, following an increase to a 31-year high at its previous meeting.
The decision was expected, although traders had considered the possibility of another move after the yen’s recent slide.
Keeping rates unchanged allowed the interest-rate gap between Japan and the United States to remain a major source of dollar demand.
The BOJ indicated that another increase could arrive sooner if underlying inflation continues to strengthen.
Intervention Delivered Only Temporary Support
The yen climbed by more than 3% on Thursday, moving toward 157.80 per dollar.
Japan did not immediately confirm the operation, but the speed and scale of the move created strong speculation that authorities had bought yen and sold dollars.
The rapid return above 160 suggests intervention changed the pace of the move without reversing its underlying direction.
Future action may prove more effective if it is supported by higher Japanese rates and a softer US dollar.
VWAP Shows Buyers Returning Above 160
The first chart uses candlesticks with a volume-weighted average price, or VWAP.
VWAP measures the average exchange rate based on estimated trading activity. Prices above it indicate that recent buyers are holding positions at a profit.
USD/JPY has recovered above VWAP after the intervention-driven decline, showing that dollar demand returned quickly.
Remaining above the indicator would keep attention on 162.00. A move back beneath VWAP could signal that yen buyers are becoming active again.

Resistance Appears Near 162.00
The first significant resistance area is positioned around 162.00.
A sustained move above this level could expose 164.00, close to the recent multi-decade high.
A daily close above 164.00 would confirm that intervention has failed to create a lasting technical ceiling.
However, the risk of another official response may rise as the pair approaches that area.
Support Begins Around 159.00
The first important support area sits near 159.00.
A break below this level could expose 157.80, the low reached during Thursday’s sharp yen rally.
A sustained decline below 157.80 would provide stronger evidence that intervention has changed the short-term trend.
Further weakness could then bring 156.00 into focus. Without a break beneath 157.80, the broader structure continues to favor dollar buyers.
Elder Ray Shows Bullish Pressure Recovering
The second chart uses the Elder Ray Index, which compares recent highs and lows with a 13-period exponential moving average.
Bull Power measures whether buyers can push price above the average. Bear Power shows how far sellers can force it below.
Bull Power has started to recover as USD/JPY rebounds from the intervention-driven decline.
Continued positive readings would support another test of 162.00. A renewed fall in Bull Power would warn that yen demand is returning.

Inflation Keeps Another Increase Possible
The BOJ has become more concerned that underlying inflation could remain above its 2% target.
Higher oil costs are particularly important because Japan relies heavily on imported energy. A weaker yen makes those imports more expensive.
Persistent inflation gives the BOJ a reason to raise rates again, even if economic growth remains uneven.
A stronger commitment to tighter policy would probably support the yen more effectively than intervention alone.
US Rates Still Favor the Dollar
The Federal Reserve’s restrictive policy stance continues to support USD/JPY.
US yields remain higher than Japanese yields, encouraging investors to borrow in yen and buy higher-returning dollar assets.
That rate advantage remains the main obstacle to a sustained yen recovery.
Softer US labor or inflation data could reduce dollar demand. Strong economic figures would reinforce the case for USD/JPY to remain elevated.
Trading Implications
USD/JPY retains a cautiously bullish outlook while trading above 159.00 and its VWAP.
A confirmed break above 162.00 could expose 164.00.
A decline below 159.00 would weaken immediate momentum, while a sustained break beneath 157.80 could shift attention toward 156.00.
Stronger BOJ guidance, further intervention, or falling US yields would support the yen. Firm American data and a wide rate gap would favor the dollar.
Conclusion
USD/JPY has returned above 160 after the Bank of Japan left rates unchanged, and the yen surrendered much of its intervention-driven gain.
Resistance is positioned near 162.00 and 164.00. Support can be found around 159.00, 157.80, and 156.00.
The broader trend still favors the dollar, but intervention risk may make price action increasingly unstable near recent highs.
