The Rubin Cult and the Marathon’s Last Mile

We’ve spent the better part of three years waiting for the "soft landing" to actually touch the tarmac. It’s the longest descent in aviation history, managed by a flight crew at the Fed that seems to have confused the runway with a scenic tour of the stratosphere. Here we are, late January 2026, and the macro picture looks less like a graceful touchdown and more like a mid-air refueling that never ends.

The UK’s December CPI print, which hit our screens a few weeks back and is still haunting the G7 bond markets, showed inflation ticking back up to 3.4%. It’s a stubborn, jagged little pill. We were told the "last mile" of the inflation fight would be the hardest, but nobody mentioned it was a marathon run in a hall of mirrors. The Bank of England is paralyzed, and the Fed, sitting on that 3.5%–3.75% range after the December cut, is staring at a labor market that refuse to break.

The markets are currently gripped by the "Vera Rubin" architecture cycle. If you aren't already hearing the term "Physical AI" five times before your first espresso, you aren't paying attention. NVIDIA is no longer a semiconductor company; it’s a theological concept. The "DeepSeek Shock" of early 2025—which briefly suggested that clever Chinese code could make massive compute spends redundant—feels like an ancient myth now. The narrative has shifted. The hype has migrated from chatbots that write mediocre poetry to humanoid robots and "Agentic AI" that supposedly manages your supply chain while you sleep.

The irony is thick. We are building "AI factories" to produce intelligence at a scale the world has never seen, yet we still can’t figure out how to get a 2% inflation target to stick.

The equity bulls are betting that Vera Rubin’s five-fold inference jump will finally deliver the productivity miracle that justifies these multiples. But look at the plumbing. The 20-year bond auctions are getting messier. The "Sovereign AI" trade—where every nation from Singapore to France builds its own domestic compute silo—is keeping NVDA at the $5 trillion gate, but it’s also a massive, inflationary capital expenditure race. We are de-globalizing the very brainpower of the planet.

On the crypto front, the Ethereum ETFs have become the boring, beige wallpaper of the institutional world. The "surprises" are gone. We’ve replaced the visceral, chaotic energy of the early 20s with the sanitized, fee-collecting machinery of Wall Street. It’s efficient, sure. It’s also a sign that the frontier has been settled, fenced in, and leased back to us at a premium.

We are living in an era of "permanent transition." Transitioning from general-purpose computing to GPUs, from global trade to sovereign clusters, and from a world of cheap money to this high-altitude plateau.

The danger isn't a sudden crash. It’s the slow, oxygen-deprived realization that this is just how things are now: expensive, complex, and perpetually on the verge of the next "industrial revolution" that always seems to require just one more trillion dollars of investment.

Stay sharp. The Rubin era is here, but the bill is still in the mail.

What I’m Watching:

• The 20-Year Auction: If the "fiscal complacency" Adam Crisafulli warned about last year finally snaps, the long end of the curve is going to get ugly.

• The "DeepSeek" Ghost: Watch for any new efficiency breakthroughs that threaten the "compute-at-any-cost" model. The Vera Rubin hype is vulnerable to a software-side rug pull.

• The BoE’s Next Move: If the UK can't get that 3.4% back under 3%, the "higher for longer" ghost is coming back for a 2026 encore.
