Volatility Views 696: The Volatility Censors Strike Again!!!

Mark SebastianGUEST
All right, here we are today at about the same interest rate, and what is our debt to GDP ratio? About 1.2.

Mark SebastianGUEST
So every move in interest rates, a tenth higher, quarter, quarter, quarter of a percent higher, um, has a entirely different ramifications for the national debt, debt servicing than it did 25 years ago the last time we were around these rates regularly.

Mark SebastianGUEST
And there is a level where we hit kind of, call it, uh, escape velocity, and the, the only way we're gonna get out of that is the Fed stepping in.

Mark SebastianGUEST
And that is, uh, that, you get a, an election, you get Anthropic, we're through the Anthro- the excitement of the Anthropic IPO.

I mean, he was speaking the language and letting basically the market know that you are not going to get away with shorting bonds.

Mark SebastianGUEST
It's still in kind of like this flux, right? You still have the 30-year at 5.25 and the 10-year at 4.7-ish.

Mark SebastianGUEST
But they stopped exploding higher, dropped, rallied, and have kind of sat here.

Which of those two movies do you prefer? Are you down for the scary movie, or are you down for the rom-com?

Mark SebastianGUEST
I think the market for now... has belief that the government is going to step in if that starts to get away again.

Mark SebastianGUEST
Now, they shot their shot on the Euro-JPY trade, but they still have other levers they're going to press.

First off, have you pulled any pearls of wisdom from your six or seven additional viewings now of the Motu film that you didn't see on the first time? And then B, what are your thoughts on this kind of wild ball week we're having, sir? And this non-farms rally

Mark SebastianGUEST
today? You know, everything I'm seeing says that, you know, on Thursday, between Thursday and Friday, Japan and the United States pulled out a liquidity bazookas, each of them, and fired it at this market and the market absolutely took off.

Mark SebastianGUEST
Now, in the process, the United States managed to piss off a bunch of Europeans because the transaction they executed was unique.

Mark SebastianGUEST
They figured out a very smart way to boost the yen without actually causing brown problems.

Mark SebastianGUEST
That might have been their one shot to do that without having to intervene in a different way.

Mark SebastianGUEST
But that liquidity has thus far held up the yen, and you combine the weak non-farms and some pretty decent earnings, and you get the 30-year coming off over.
