Yen Weakness Defies BoJ Hike as Dollar Holds Above 100 | 18th September, 2026

Yen Weakness Persists

Global FX markets are reacting to a notable divergence between the Bank of Japan's rate decision and the Japanese Yen's market reaction. The BoJ raised its policy rate by 25 basis points to 1.25%, the highest level since 1995, but the Yen weakened as investors focused on the absence of a clearly more aggressive tightening signal and two dissenting policymakers. This has lifted AUD/JPY, EUR/JPY and GBP/JPY, while the US Dollar Index continues to hold above 100.00 following the Federal Reserve's recent tightening signal.

USD/JPY Forecast

Current Price and Context

USD/JPY rises as the Japanese Yen weakens despite the BoJ delivering a widely anticipated 25-basis-point rate hike to 1.25%. The Yen's decline reflects expectations that the BoJ may proceed cautiously with additional tightening, while the recent Fed hike keeps the US-Japan rate differential historically wide.

Key Drivers

• Geopolitical Risks: Middle East tensions and energy prices could influence Japanese inflation and safe-haven demand for the Yen.

• US Economic Data: Strong US data could keep Treasury yields elevated and support USD/JPY.

• FOMC Outcome: The Fed's recent tightening signal continues to provide support for the Dollar.

• Trade Policy: US-Japan trade developments and currency-policy discussions could influence Yen sentiment.

• Monetary Policy: The BoJ's willingness to raise rates further, and the pace of future hikes, will be crucial for USD/JPY.

Technical Outlook

• Trend: Bullish above 155.00.

• Resistance: 157.00 / 158.00.

• Support: 155.00 / 153.50.

• Forecast: Holding above 155.00 keeps the near-term bullish structure intact, while a break below 153.50 would signal renewed Yen strength.

Sentiment and Catalysts

• Market Sentiment: Bullish USD/JPY.

• Catalysts: BoJ guidance, US yields, Fed policy expectations, Japanese inflation and currency-policy developments.

AUD/JPY Forecast

Current Price and Context

AUD/JPY rises as the Australian Dollar gains against the Yen following the BoJ's rate hike. Despite the increase in Japanese borrowing costs, the market reaction has favored the Australian Dollar as traders assess the BoJ's cautious guidance and the possibility of a slower tightening path.

Key Drivers

• Geopolitical Risks: Global risk sentiment and Middle East developments remain important for the risk-sensitive Australian Dollar.

• US Economic Data: US yields and Federal Reserve policy can influence global carry-trade conditions.

• FOMC Outcome: The Fed's tightening stance can affect risk appetite and global rate differentials.

• Trade Policy: Australia's exposure to China and global commodity trade remains important for AUD.

• Monetary Policy: The relative outlook for the RBA and BoJ will remain a key driver of AUD/JPY.

Technical Outlook

• Trend: Bullish above 110.00.

• Resistance: 112.00 / 113.00.

• Support: 110.00 / 109.00.

Sentiment and Catalysts

• Market Sentiment: Bullish.

• Catalysts: BoJ guidance, RBA expectations, commodity prices, China-related developments and global risk appetite.

EUR/JPY Forecast

Current Price and Context

EUR/JPY gains momentum as the Yen weakens following the BoJ's 25-basis-point rate hike. The pair is benefiting from the immediate market interpretation that the BoJ's policy normalization may remain gradual, allowing the Euro to strengthen against the Japanese currency.

Key Drivers

• Geopolitical Risks: European energy exposure and broader geopolitical tensions remain important risks for the Euro.

• US Economic Data: US yields can influence global currency positioning and risk appetite.

• FOMC Outcome: The Fed's tightening stance can affect cross-currency flows and carry-trade demand.

• Trade Policy: European trade developments and global economic conditions can influence EUR sentiment.

Technical Outlook

• Trend: Bullish above 178.00.

• Resistance: 180.00 / 181.00.

• Support: 178.00 / 176.50.

• Forecast: Holding above 178.00 keeps the bullish structure intact, while a break above 180.00 could extend the recovery.

Sentiment and Catalysts

• Market Sentiment: Bullish.

• Catalysts: BoJ guidance, ECB policy expectations, Eurozone data and global risk sentiment.

GBP/JPY Forecast

Current Price and Context

GBP/JPY rises to a two-week high as the Yen weakens following the BoJ's rate increase. Sterling is benefiting from the immediate repricing of Yen expectations, with traders now focusing on the BoJ's forward guidance and whether another hike is likely in the coming months.

Key Drivers

• Geopolitical Risks: Global risk sentiment and energy prices could affect both Sterling and the Yen.

• US Economic Data: Changes in US yields can influence global carry trades and cross-currency positioning.

• FOMC Outcome: Fed policy remains relevant through its effect on global rate differentials.

• Trade Policy: UK trade developments and global growth expectations can influence GBP.

• Monetary Policy: The BoE-BoJ policy differential remains a key factor for GBP/JPY.

Technical Outlook

• Trend: Bullish above 207.00.

• Resistance: 209.00 / 210.00.

• Support: 207.00 / 205.50.

• Forecast: A sustained move above 209.00 could extend the recovery toward 210.00, while a break below 205.50 would weaken the bullish setup.

Sentiment and Catalysts

• Market Sentiment: Bullish.

• Catalysts: BoJ guidance, UK economic data, BoE expectations and global risk sentiment.

US Dollar Index (DXY) Forecast

Current Price and Context

The US Dollar Index remains firmly above 100.00 as the market digests the Federal Reserve's recent rate hike and continues to assess the outlook for further tightening. The Dollar is also benefiting from its relative yield advantage, although the BoJ's latest decision introduces another important central-bank policy variable for global FX markets.

Key Drivers

• Geopolitical Risks: Ongoing geopolitical uncertainty can support safe-haven demand for the US Dollar.

• US Economic Data: Strong economic activity and persistent inflation could reinforce expectations for further Fed tightening.

• FOMC Outcome: The Fed's latest policy decision remains an important support for the Dollar.

• Trade Policy: Global trade uncertainty can contribute to defensive USD demand.

• Monetary Policy: The relative pace of Fed and BoJ tightening will remain a major influence on global currency flows.

Technical Outlook

• Trend: Bullish above 100.00.

• Resistance: 100.50 / 101.00.

• Support: 100.00 / 99.50.

• Forecast: Holding above 100.00 keeps the bullish structure intact, while a break above 100.50 could expose the 101.00 area.

Sentiment and Catalysts

• Market Sentiment: Bullish.

• Catalysts: Fed guidance, Treasury yields, BoJ policy, US economic data and geopolitical developments.

Wrap Up

The BoJ's 25-basis-point rate hike to 1.25% has not translated into immediate Yen strength, with markets instead focusing on the cautious policy signal and dissent within the central bank. As a result, AUD/JPY, EUR/JPY and GBP/JPY have moved higher, while USD/JPY remains supported by the broader US rate advantage. The Dollar Index continues to hold above 100.00, keeping global FX markets focused on the evolving divergence between Fed and BoJ policy.
