Inflation, the Yen, and a Market at a Crossroads
The yen is standing at a critical inflexion point, and inflation is part of what makes the moment uneasy. In the same stretch of trading, the currency has slipped below a short-term uptrend, while attention is shifting toward major US data and the outcome of US-Iran peace talks in Islamabad.
Why is the yen being watched so closely now?
After breaking below an uptrend that began on 16 February, the yen also moved beneath its 10-day and 20-day exponential moving averages. That combination has raised the possibility that the recent pattern is changing, especially with support now under pressure near ¥158. 5 in USD/JPY.
If that support gives way, the next level is seen near ¥157. 5, and a further move could take USD/JPY toward the ¥154. 5-¥155 range. If the yen stabilizes and reclaims its prior uptrend, there is still room for a move back toward the 2022 highs in the ¥161. 5-¥162 area. The relative strength index is also declining, suggesting momentum may be turning.
How does inflation shape the next move?
Inflation is not just a background statistic here; it is part of the market’s reading of Japan’s next policy steps. In Japan, inflation has been gradually easing, with most measures near or below the 2% target. That matters because the market is trying to judge whether the Bank of Japan has enough room to move, or whether it will wait for more clarity.
The context is broader than one currency pair. The end of the war between the US and Iran, if it comes, could improve business sentiment and change the policy discussion. But the present uncertainty is keeping markets cautious, and a breakdown in talks would likely strengthen the dollar again. A peaceful outcome, on the other hand, would weigh on the greenback through renewed rate cut expectations and the unwinding of positioning built in March.
What are traders and institutions looking at next?
Traders are focused on a narrow band of levels, but the story is bigger than the chart. CMC Markets Singapore Pte. Ltd., a regulated financial services firm, notes that the yen can strengthen during periods of risk aversion because it is often seen as a safe-haven currency. That dynamic could matter again if tensions between the US and Iran intensify.
At the same time, prices remain a headwind for USD/JPY. Rising oil prices tend to weigh on the pair, while falling oil prices may help stabilize it. In the near term, the market is also waiting on major US economic data, including the non-farm payroll report on 3 April, as well as the US CPI report and the University of Michigan Consumer Sentiment survey.
What would change the outlook from here?
The next few sessions hinge on whether support holds and whether geopolitical tension eases rather than escalates. On the daily chart, USDJPY did not reach 157. 65 support and instead bounced around the 158. 00 handle. On the 4-hour chart, price is still struggling around the 159. 30 resistance zone, while the 1-hour chart shows buyers trying to defend an upward trendline.
For now, the picture is balanced but fragile. The yen has already shown signs of pressure, and inflation is one of the reasons markets are paying close attention to Japan’s policy backdrop. If support cracks, the move could deepen quickly; if it holds, the reversal story remains alive. In either case, the opening scene of a currency leaning on thin support may soon look less like a technical moment and more like a turning point.
