USD/JPY enters Monday trading with the US Dollar firmly supported against the Japanese Yen after the pair surged 0.63% on Friday and reached a daily high of 158.06 before pulling back toward 156.95-156.98.

The Japanese Yen weakened despite the Bank of Japan (BoJ) raising its policy rate by 25 basis points to 1.25%, its highest level in 31 years. The decision was broadly anticipated by markets, shifting attention toward the BoJ’s forward guidance rather than the rate increase itself.

At the same time, expectations of additional Federal Reserve tightening have supported the US Dollar and US Treasury yields. The US 10-year Treasury yield has moved toward 4.98%, while the US Dollar Index (DXY) remains above 100.50, close to a seven-week high.

The result is a widening yield advantage for the US Dollar and continued upward pressure on USD/JPY.

Technically, the pair remains above both its 100-hour SMA at 155.60 and 200-hour SMA at 154.73, keeping the short-term structure constructive. The key upside level for Monday is 158.00, while 156.50 and 155.60 provide important downside support.

USD/JPY Price Today: Dollar Remains Firm Above 156

The key development heading into Monday is that USD/JPY remains elevated despite the BoJ’s latest rate increase.

The pair initially climbed to 158.06 before sellers pushed it back below the 157.00 area.

However, the pullback has so far remained relatively contained.

USD/JPY continues to trade above the 100-hour SMA at 155.60 and 200-hour SMA at 154.73, meaning the broader short-term bullish structure remains intact.

For Monday, traders will therefore be watching whether buyers can regain the 157.00 area and challenge 158.00 again.

Why Did the Yen Fall After the BoJ Rate Hike?

The Yen’s reaction to the BoJ decision may initially appear unusual because Japanese interest rates were increased by 25 basis points to 1.25%.

However, the rate hike was already largely anticipated by financial markets.

When an expected rate decision is fully or substantially priced into currency markets, the subsequent reaction often depends more heavily on what the central bank communicates about future policy.

BoJ Governor Kazuo Ueda reiterated that the central bank could continue raising rates if economic and price developments warrant additional tightening.

However, the BoJ also highlighted uncertainties surrounding the Middle East, artificial-intelligence-related demand and foreign-exchange market volatility.

That combination has limited expectations for an aggressive sequence of additional rate increases.

Japanese Inflation Keeps BoJ Expectations in Check

Japan’s latest inflation data also remain important for the Yen.

National consumer-price inflation was unchanged in August, while underlying inflation remained below the BoJ’s 2% annual target.

That provides a reason for markets to moderate expectations regarding the pace of future BoJ tightening.

If investors begin to believe that Japanese rates will rise only gradually, the Yen may struggle to gain significant support from the current policy cycle.

The market is therefore watching not simply the level of the BoJ policy rate, but the potential speed and scale of future increases.

Federal Reserve Expectations Support the US Dollar

The US Dollar is benefiting from a contrasting monetary-policy environment.

The Federal Reserve increased its benchmark interest rate by 25 basis points to 3.75%-4.00%, marking its first rate increase since 2023.

The move reflects continued concern about inflation risks, particularly as higher energy prices place renewed pressure on inflation expectations.

Markets have also increased expectations for another US rate increase.

According to the CME FedWatch data cited in the source material, markets were pricing around a 55% probability of another 25-basis-point increase at the October meeting, compared with approximately 40% before the Fed’s latest decision.

This repricing has helped support the Dollar against major currencies, including the Japanese Yen.

US Treasury Yields Strengthen the Dollar’s Advantage

US Treasury yields are another major driver of USD/JPY.

The 10-year US Treasury yield has recovered toward 4.98%, approaching the 5.04% high reached earlier in the week.

Higher US yields increase the relative return available from US-denominated assets compared with Japanese assets.

With the BoJ policy rate at 1.25% and the Fed target range at 3.75%-4.00%, the interest-rate differential remains substantial.

This yield gap is one of the most important fundamental factors supporting USD/JPY.

If US Treasury yields continue to rise while Japanese yields remain comparatively restrained, the Dollar could retain an advantage against the Yen.

USD/JPY Technical Analysis for Monday

The hourly chart continues to show a constructive short-term structure.

USD/JPY remains above the 100-hour SMA at 155.60 and 200-hour SMA at 154.73.

The Relative Strength Index has eased back toward 51, indicating that the overbought conditions seen earlier in the week have unwound.

That leaves room for another upside attempt if buyers successfully defend the current support region.

The first major resistance remains 158.00.

A sustained move through 158.00 would place the recent 158.06 high immediately back into focus and could signal another attempt to extend the advance.

On the downside, 156.50 is the first important support area.

A deeper correction would expose 155.60-155.50, followed by the 200-hour SMA at 154.73.

Bullish Sentiment

1. US-Japan Rate Differential Remains Significant

The Fed’s 3.75%-4.00% target range remains well above the BoJ’s 1.25% policy rate, maintaining a substantial yield differential in favour of the US Dollar.

2. US Treasury Yields Are Elevated

The US 10-year yield remains close to 5%, reinforcing the Dollar’s yield advantage and supporting USD/JPY.

3. USD/JPY Remains Above Key Moving Averages

The pair is holding above the 100-hour SMA at 155.60 and 200-hour SMA at 154.73, keeping the short-term technical structure constructive.

4. DXY Remains Above 100.50

The US Dollar Index is trading above 100.50, close to a seven-week high, showing that the Dollar’s strength extends beyond the Japanese Yen.

5. 158.00 Remains Within Reach

USD/JPY has already tested 158.06, meaning another move toward the 158.00 area remains technically relevant while support holds.

Bearish Sentiment

1. The BoJ Has Begun Raising Rates

The BoJ has lifted its policy rate to 1.25%, its highest level in 31 years, and continues to leave the possibility of further tightening open.

2. 158.00 Is a Significant Resistance Area

The pair has already encountered selling pressure around 158.00, meaning another approach to this level could attract renewed supply.

3. Japanese Policy Could Become More Restrictive

If inflation and economic conditions strengthen sufficiently to justify additional BoJ tightening, expectations for a narrower US-Japan rate differential could increase.

4. A Fall Below 156.50 Would Weaken the Immediate Structure

A sustained move below 156.50 would increase downside pressure and bring the 155.60-155.50 support zone into focus.

5. A Deeper Correction Could Target 154.73

A break below the 100-hour SMA would expose the 200-hour SMA at 154.73, an important level for the broader short-term structure.

USD/JPY Price Forecast: What Traders Are Watching Monday

The 158.00 level is the main upside reference for Monday.

A sustained break above this area would strengthen the bullish technical structure and place the recent 158.06 high back into focus.

If buyers fail to overcome 158.00, traders could instead see a period of consolidation or another pullback.

The first downside level is 156.50.

A break below 156.50 would increase attention on:

155.60 → 155.50 → 154.73

The 155.60 level is particularly important because it corresponds with the 100-hour SMA, while 154.73 represents the 200-hour SMA.

The current technical map is therefore:

Upside: 157.00 → 158.00 → 158.06

Support: 156.50 → 155.60 → 155.50 → 154.73

The US Dollar-Yen Yield Differential Remains Central

USD/JPY continues to reflect the substantial difference between US and Japanese interest rates.

The Fed’s policy rate is currently 3.75%-4.00%, compared with the BoJ’s 1.25%.

However, currency markets are forward-looking.

The direction of USD/JPY will depend increasingly on whether investors expect the Fed to continue tightening while the BoJ proceeds cautiously, or whether the Japanese central bank accelerates its tightening cycle.

The US 10-year Treasury yield is therefore an important variable to watch alongside BoJ communications and Japanese inflation data.

Currency Hedger View

USD/JPY remains one of the most important currency pairs for monitoring the interaction between US and Japanese monetary policy.

Today Markets View

USD/JPY begins Monday with the US Dollar maintaining a clear yield advantage, despite the BoJ’s latest 25-basis-point rate increase.

The pair’s ability to remain above 156.50 keeps the immediate technical structure constructive, while 155.60 and 154.73 provide deeper support.

Above the market, 158.00 remains the critical resistance level after Friday’s move to 158.06.

The fundamental picture remains closely tied to the US-Japan interest-rate differential. Further increases in US Treasury yields or stronger expectations for another Fed rate hike could continue supporting the Dollar, while evidence of faster BoJ tightening could provide greater support for the Yen.

For Monday, traders will therefore focus on whether USD/JPY can reclaim and sustain levels above 157.00, or whether resistance around 158.00 triggers another correction toward 156.50.
