USD/JPY 4-hour chart showing the pair falling to 157.24 after breaking below the August range

USD/JPY Forecast: 157.24 Breaks the August Range

By Saqib Iqbal2 min read
  • 157.24 on USD/JPY, down 0.9% on the day, after a two-session decline cleared the entire August trading range.
  • The Bank of Japan's 1.00% policy rate and its stated intent to keep tightening have finally started to compress the rate spread that supported this pair all year.
  • 157.00 is the immediate floor; losing it opens the way toward 156.50 with no recent structure in between.

Fundamental Analysis: USD/JPY

The story in USD/JPY has changed shape. For most of 2026 the pair traded as a pure carry vehicle, with the Bank of Japan at or near zero and the Federal Reserve holding a restrictive stance. June's hike to 1.00%, the highest Japanese policy rate since 1995, and the 31 July decision to hold there, ended the first half of that equation. Governor Ueda has said the board will continue raising rates while financial conditions remain accommodative, and the BoJ raised its FY2027 core inflation projection to 2.4%, which is not the profile of a central bank about to stop.

The dollar side has not moved to offset it. The Fed held at 3.50% to 3.75% for a fifth consecutive meeting on 29 July, and while three members dissented in favour of a hike, the committee's base case remains patience. US annual inflation slowed to 3.4% in July from 3.5%, with core at 2.5%. A spread that narrows because one side is rising while the other stands still is the least comfortable configuration for a crowded carry position.

The practical consequence is that the pair has become sensitive to Japanese commentary in a way it was not three months ago. Nothing in the last week changed the level of either policy rate, but the market's willingness to hold the position at 160 evaporated. That is a positioning problem before it is a valuation one, and positioning problems tend to resolve faster than fundamental ones.

Technical Analysis: USD/JPY

The 4-hour chart shows a clean range break rather than a trend continuation. Through the second half of August the pair oscillated between roughly 158.30 and 160.00, tagging 160.50 on 1 September before turning. The decline that followed was near vertical, cutting through the range floor without pausing and printing 157.24. All four moving averages are now clustered between 159.07 and 159.77, several figures above spot, which tells you how quickly the move happened relative to the trend that preceded it.

Resistance is 158.00 first, then 158.50, with the 159.07 to 159.77 average band the level that would matter for anyone arguing this is only a correction. Support is 157.00, and below that 156.50, where the chart has no recent structure to lean on. A sustained recovery above 158.50 would suggest the break was a liquidation flush rather than a change of trend and would invalidate the bearish read.
