US and Japan Intervene to Support Yen Amidst Market Confusion

The United States and Japan have jointly intervened in currency markets to prop up the Japanese yen, a move that has drawn scrutiny and questions about the US's motives. The yen had recently hit a 40-year low against the dollar, with one dollar fetching 164 yen.

In a coordinated effort, the US and Japan purchased yen, a move aimed at combating "excessive volatility and disorderly movements." Japanese Finance Minister Katayama Satsuki confirmed the intervention, stating that Japan's Finance Ministry remains in close contact with its US counterpart and will not hesitate to undertake further joint actions. Her US counterpart echoed these sentiments.

The intervention saw the yen strengthen to 155 yen per dollar following the announcement, though it has since softened slightly to 157 yen. The yen has been significantly undervalued for some time, making Japanese exports cheaper but imports, particularly energy, more expensive. This is exacerbated by rising energy prices due to the conflict in the Middle East, as Japan imports a substantial portion of its energy and pays for it in dollars.

While the intervention's mechanics are understood – buying yen increases its demand and thus its value – the rationale behind the US's decision to support Japan at this particular juncture remains a subject of speculation. The article draws a parallel to Mario Draghi's "whatever it takes" statement during the euro crisis, highlighting the significant effort and confidence required to manage currency values, but questions whether this intervention will be as successful.

The Japanese Ministry of Finance continues to be in close contact with the US Treasury Department. We will not hesitate to undertake further joint interventions.
