The USDJPY had been trading steadily higher in February, from the 128.50 support level, up toward the 137 round number resistance level. This move was driven by a combination of fundamental reasons (strengthening of the DXY and overall weakness of the Japanese Yen) and technical setup (the golden cross, where the 50-period Moving Average crossed over the 200-period Moving Average). This week, the Bank of Japan (BoJ) is set to release its latest decision on its Policy Rate and the accompanying Monetary Policy Statement.
The BoJ is expected to persist with its current stance, maintaining an ultra-lose monetary policy approach as it is the last BoJ policy meeting for Governor Kuroda. However, last week, the yield on the 10-yr Japanese Government Bonds (JGBs) consolidated slightly above the 0.5% ceiling adjusted by the BoJ on 20th December 2022. Following the announcement of the increased yield limit, the Japanese Yen strengthened significantly, with the USDJPY trading down from 137.30 to 130.60.
The markets are now watching if the BoJ would take on a similar action again. As the DXY weakened toward the end of the week, the USDJPY was dragged lower, reversing from the 137 resistance level, down to the 135.80 price level to test the 50-period Moving Average. If the price breaks below the Moving Average support level, the USDJPY could trade down to the key support level of 134.50 which coincides with the 38.3% Fibonacci Retracement level.
If the BoJ were to further adjust the yield limits on the 10-yr JGBs, the USDJPY could see a continuation of the downside beyond 134.50, with the next key support level at the 133 price area, formed by the round number and 61.8% Fibonacci Retracement level.

FX markets enter an important window with a Federal Reserve policy decision and press conference, US ISM activity data, German inflation releases, China PMIs, and Australian labour figures all due.
Quick facts
The upcoming Fed policy decision and press conference are closely watched for guidance on the potential timing of rate cuts, with implications for US Treasury yields and USD direction.
Broad USD selling has intensified over the last 48 hours. The move has coincided with renewed tariff rhetoric and heightened sensitivity to FX intervention narratives.
ISM Manufacturing PMI is scheduled for Monday, 2 February, with ISM Services PMI on Wednesday, 4 February, providing timely insight into US growth momentum.
German CPI, euro area GDP and unemployment, China PMIs, and Australian labour data provide regional context, particularly for EUR and AUD crosses.
USD/JPY
What to watch
The Federal Reserve decision and subsequent press conference are key events influencing US Treasury yields.
Any shift in tone around inflation progress, economic risks, or rate cut timing expectations may affect yield differentials and near-term USD sensitivity.
Recent broad USD weakness, reinforced by tariff-related headlines and intervention sensitivity, has added downside pressure to the USD.
On the JPY side, Japan inflation signals, including Tokyo CPI, are relevant as indicators of domestic price trends and potential policy direction.
Key releases and events
Thu 30 Jan: Japan Tokyo CPI (January)
Thu 30 Jan: Federal Reserve policy decision and press conference
Mon 2 Feb: US ISM Manufacturing PMI
Wed 4 Feb: US ISM Services PMI
Technical snapshot
USDJPY has broken lower from its recent consolidation zone, with downside range evident over the last 48 hours. Price has moved down to the 200-exponential moving average (EMA) and is testing a level not seen since October 2025.

EUR/AUD
What to watch
Alongside euro area growth numbers, Australian employment data may influence near-term EUR/AUD sensitivity ahead of the RBA policy decision next week.
China's official PMIs remain relevant, as shifts in Chinese activity expectations can influence AUD via commodity demand and regional risk sentiment.
