Japanese Yen Undervaluation Warning: What It Means for ASX and Commodity Traders

๐Ÿ“… Published AEST

What Happened

Currency strategist Geoff Yu at BNY has highlighted that the Japanese Yen (JPY) is still significantly undervalued on a Real Effective Exchange Rate (REER) basis, even as the Euro and US Dollar valuations have moved closer together. USD/JPY currently trades around 154.50, well above the long-run fair value range that many analysts place near 130.00โ€“135.00. The gap represents one of the largest valuation dislocations in the G10 currency space.

Key Levels โ€” USD/JPY

  • Support 1: 152.00 โ€” recent consolidation floor and psychological level
  • Support 2: 149.40 โ€” the April 2024 intervention zone watched closely by the Bank of Japan
  • Resistance 1: 156.00 โ€” near-term ceiling where selling pressure has emerged
  • Resistance 2: 158.50 โ€” 2024 multi-decade high, a break above would escalate intervention risk sharply

Technical Picture

USD/JPY remains in a broad uptrend on the weekly chart, trading above its 50-day moving average (~152.80) and 200-day moving average (~151.20). However, RSI on the daily chart is sitting near 62 โ€” not yet overbought, but approaching territory where prior rallies have stalled. A weekly close below 152.00 would be a meaningful technical warning sign.

What Traders Are Watching

Australian traders should monitor USD/JPY closely because a rapid Yen strengthening event โ€” triggered by Bank of Japan policy shifts or coordinated G7 intervention โ€” could hit risk assets hard. Historically, a sharp Yen rally has pressured the ASX 200 (watch support at 7,750), weighed on iron ore (currently ~$105/tonne, support at $98), and provided a short-term boost to gold (resistance at $2,400). A move through 149.40 on USD/JPY would be the clearest trigger signal.

Bias

Bearish USD/JPY (Yen bullish bias) โ€” The extreme REER undervaluation identified by BNY, combined with growing Bank of Japan policy normalisation pressure, tilts the medium-term risk toward a stronger Yen. Traders should treat any rallies toward 156.00โ€“158.50 as potential selling opportunities rather than breakout entries.
