Central Banks Discover Ctrl+Z Function on Currency Markets

The United States joined Japan in propping up the yen after decades of standing on the sidelines watching their currency get demolished. Historic stuff. Two countries decided numbers should be different numbers.

Japan's been begging for help since the yen started circling the drain. Washington finally caved. The reason? Nobody knows. The Treasury Department released a statement that translated to "we felt like it." Coordinated intervention sounds impressive until you remember it's just two groups of people buying and selling the same pieces of paper everyone else trades but pretending their trades matter more because they work for governments.

What's at stake? Everything, according to the headline. Also nothing. The yen goes up, the yen goes down. Retail traders who loaded up on USD/JPY calls last week are now discovering their Robinhood accounts look like a crime scene. They read an article about yen weakness being structural and permanent. Took out margin. Now they're Googling "what is coordinated intervention" while their positions bleed out in real time.

The coordinated intervention worked for approximately sixteen hours before currency markets remembered that Japan's got a debt-to-GDP ratio that would make a payday loan company blush and the United States prints money like it's competing for a Guinness record. But sure, a few billion in FX intervention will solve that.

Some analyst on CNBC called this "a pivotal moment in global monetary policy." He got paid to say that. You did not get paid to hear it. The yen moved three percent, then gave back half of it by lunch. Retail traders set stop losses at exactly the wrong level because they watched a YouTube video titled "Master Forex Trading in 8 Minutes."

The Treasury and the Bank of Japan high-fived over Zoom and declared victory. The yen is saved until next Thursday when it implodes again and everyone acts surprised.
