Will USD/JPY Break Below 155?US Dollar vs Japanese YenCFI:USDJPYCFIUSDJPY has been on a steady march higher since mid-2025, climbing from the 142s all the way to test the psychologically and technically critical 160.000 resistance zone. That level has history; it sits inside a supply zone that has repelled price before, and with the Bank of Japan increasingly vocal about yen weakness, any sustained break above 160 carries significant intervention risk. The rejection at 160 was swift and decisive. Price spent several sessions compressing just beneath that ceiling inside a tight consolidation box before sellers took control, wiping out nearly 400 pips. 100 Simple Moving Average: The 100-day SMA at 157.301, which had been rising support for months, has now flipped to overhead resistance as price trades below it for the first time since early 2026. Relative Strength Index: The RSI has not yet printed below 30, which means a deeper flush remains possible before any bounce trigger fires. This mirrors the February 2026 RSI behavior, which dipped below 30 before the recovery rally launched. Fundamental outlook: The BOJ has been gradually tightening policy, which reduces the interest rate differential that drove the yen's multi-year weakness. Any sustained move below 155.000 would likely trigger fresh BOJ commentary, if not direct intervention.
