The yen briefly hit ¥160 against the dollar here on Monday. JPY fell too against other major currencies. USD/JPY hit its highest since April 1990. CFTC data published on Friday, for the week ended April 23, showed hedge funds and speculators held the largest short yen position in 17 years. This would ordinarily be a reason to be wary of further yen losses but this didn’t impact. The renewed plunge in the yen was driven by both stop loss buying (despite huge yen shorts there were plenty of yen longs looking for a change of trend) and the triggering of barrier options circa 160.00. Highs seen after 160.00 broke were just over 160.20 (160.245 sighted on EBS) before the pair reversed almost as quickly down to around 159.30.

As a reminder, the downtrend in JPY is long-standing and, in summary, is driven by:

  • Sticky US inflation is going to keep the Fed higher for longer
  • And thus the gaping US-Japan yield differential will continue to underpin USD/JPY
  • Add in subdued Japanese inflation data
  • And the dovish BOJ on hold again last week

While I have been very dismissive of potential intervention from the Bank of Japan (ps. its Japan’s Ministry of Finance that will instruct the BOJ when to intervene) the move above 160 could well be described as rapid (well, this is not in doubt!) and disorderly. These are key trigger points for the MoF. I do maintain, though, that intervention will be a waste of Japan’s USD holdings. Given those points above, a driving down of USD/JPY by intervention will just present a dip buying opportunity for those happy with the 500 or so pips of carry on offer.

As a side note, today was a market holiday in Japan and liquidity was somewhat thinned out by the absence of Japanese markets. We heard nothing at all from Japanese officials. No verbal support at all was offered for the JPY.

Elsewhere, and notable, property sector shares in China rose strongly, helped along by further support moves over the weekend:

Oil dribbled lower, the prospect of a ceasefire in Gaza cited, along with the likelihood of a more hawkish sounding Federal Reserve this week (the Federal Open Market Committee (FOMC) statement is due Wednesday).
