On Friday we questioned what stage
The BOJ reached for to gauge
If yen intervention
Would soon get a mention
And could Katayama assuage
 
The markets, without spending dough
Since Friday, we’re now in the know
That Bessent checked rates
With yen reprobates
Now anxious to deal a deathblow

On Friday, I asked the question whether the movement seen in Tokyo after the BOJ meeting was finished consisted of step six, rate checks, or step seven, intervention.  Of course, my comments preceded the NY session and then in the afternoon, as you can see from the below chart, something much more substantial occurred.

At this point on Sunday evening, it appears that about 11:00 Friday morning in NY, as Europe was heading home for the weekend, the Fed rang into major dealers around the Street and asked for prices where they could buy yen / sell dollars.  This is the very definition of ‘rate checks’ and the market response was exactly what you would expect.  The sequence of events was almost certainly that the Japanese MOF reached out to the Treasury department who then rang up the Fed and asked them to act. (Remember, currency policy is a Treasury function, not a Fed one). As you can see from the chart above, the initial move when Asia opened was a continuation of the yen’s strength, and in truth dollar weakness against most currencies, but we have already seen the initial bounce (the green bars to the right.)

Here’s the thing about rate checks, and in truth, every monetary policy, the law of diminishing returns is in effect here, so the next time they try it, and I would not be surprised to see something again tonight or tomorrow in NY, it will have a smaller impact.  Now, perhaps they are comfortable at 155 instead of pressing 160 and if USDJPY stabilizes here, things will go on much as before.  But I doubt that without further efforts, including direct intervention, things are going to change.  And even then, as history has shown time and again, intervention’s impact typically wears off after a few months.  The only way to truly change this trajectory is to change policy in Japan, and by all accounts, as the country heads into an election where PM Takichi’s platform is ‘run it hot’ that seems unlikely.  

It may not be a fade today, but at 150 or so, I expect that the risk/reward of selling yen is going to be extremely attractive again.

Have a good evening
