USD/JPY: Japan was just given every excuse to trigger BOJ intervention. April 29, 2024

By :David Scutt, Market Analyst

  • USD/JPY spikes above 160, the highest level since 1990
  • Move was not driven by rate differentials with US Treasury markets closed
  • The move looks speculative, a potential trigger for the Japanese government to instruct the BOJ to intervene in FX markets

If Japan’s Ministry of Finance (MOF) was looking for a trigger to instruct the Bank of Japan (BOJ) to intervene in currency markets, they were just provided a big one. Because out of nowhere, on a public holiday in Japan, USD/JPY just suddenly spiked over 1%, seeing it briefly trade above 160 for the first time since 1990, taking out a key topside level.

USD/JPY spike driven by speculative forces

While USD/JPY upside is not unusual, what makes this move different to others is that it was not underpinned by any significant shift in fundamentals. US Treasuries are not trading due to the public holiday in Tokyo meaning the key driver of USD/JPY – ballooning yield differentials between the US and Japan – did not contribute to upward thrust. Nor was there any significant change in risk appetite in Asia which is broadly a continuation of what was seen in Europe and North America on Friday.

And a deliberate attempt to bring an official policy response

No, the move looks entirely speculative. And, if I’m we’re honest, a deliberate attempt from a party or parties to bring the MOF from the sidelines. Suzuki, Kanda and other senior Japanese government officials have been warning for months about taking action to quash speculative movements. If they don’t instruct the BOJ to intervene following today’s abrupt bounce, when will they ever?

Traders should now be on heightened alert for this risk.

Key near-term USD/JPY levels

After 160, the next topside level for USD/JPY is 165. On the downside, USD/JPY has been supported on dips below uptrend support dating back to early April, including a suspected “market check” from the MOF last Friday. The low of 155 hit then is the first level for traders to watch with 152 the next major level after that.
