Arthur Burns walked this corridor in 1971. Nixon wanted low rates before the election. Burns delivered. Political accommodation + supply shock = stagflation that took Volcker 20% rates and a recession to break. The Fed faces the same corridor now. Tariff inflation is supply-side. Pressure to cut is mounting. If the Fed blinks — as Burns did — the 18-month lag means the next inflation wave arrives while rates are already falling. Same pattern. Different Fed. Same playbook.

The yen carry trade is not a Japan story. Borrow cheap yen. Sell yen. Buy global risk assets. When the BOJ tightens, this runs in reverse — yen rises, funding costs spike, positions unwind globally. August 2024: a modest BOJ move erased trillions in market cap in days. Not from earnings revisions. From a funding mechanism reversing. The BOJ is setting global risk appetite, whether markets acknowledge it or not.

The dollar system that controls global trade doesn't run through the Federal Reserve. It runs through a parallel system — the Eurodollar market — that the Fed can't directly control, doesn't regulate, and can only influence through swap lines. Most people have never heard of it. Here's why it matters.

Private credit's reported 2% default rate is an accounting artifact. When a borrower can't pay, the fund extends the loan. No default recorded. No loss marked. That's how $2+ trillion in shadow credit reports "manageable stress" while analysts tracking covenant waivers and maturity extensions see 8-9%. The real exposure lives in the banks: $500B in unused credit lines committed to these funds. They find out what they own when the extensions run out.

M2 money supply is growing again after contracting in 2022-23. The Fed's research puts the M2-to-inflation lag at 18-24 months. Everyone's debate is about when the Fed cuts. The question nobody's asking: if M2 re-acceleration is already in progress, what does the inflation picture look like in late 2027? The first lag caught everyone off guard. Why would this one be different?

57% of central bank gold buying in 2025 was never reported at time of purchase. Total disclosed: 863 tonnes — nearly double the pre-2022 average. But the majority moved anonymously. Sovereign buyers with non-commercial motives, operating in opacity. The price you observe is set in a market where the largest buyers are hiding their size.

March CPI: 3.3%. Energy +10.6% m/m. The war is in the print. In 1980, CPI peaked at 14%. Volcker gets the credit — but oil hit its high in Nov 1980, Saudi Arabia doubled output through 1981–82. The deflationary mechanism was already set while the headline looked catastrophic. Same structure today: $166B in IEEPA tariff refunds flows ~Apr 20. That's the goods-price reset already in the pipeline. The headline is the lag. The mechanism is what matters.

The dollar stopped being a safe haven during the tariff shock. Risk-off used to mean dollar up. This time: dollar sold off with equities. That's not noise — it's the mechanism shifting. When the reserve currency is weaponized, foreign central banks don't flee to it. They flee from it. The weapon is pointed at everyone holding dollars.

The dollar's reserve premium is what makes US deficits cheap to finance. Holding reserves means buying Treasuries — that's demand the US gets for free. Weaponizing the dollar erodes that demand. Sanctions, frozen reserves, blocked payment rails — each action reduces the incentive to hold dollars. Central banks diversify. The premium compresses. Yields drift higher. Tariffs are self-funding on paper. In practice, they're slowly raising the cost of the debt they're supposed to help retire.

UMich consumer sentiment just hit 47.6 — a record low. 1-year inflation expectations jumped to 4.8%. Most analysts are filing this as 'consumers are unhappy.' The more interesting question: when do sentiment readings become self-executing?

China's PPI just exited 41 months of deflation. For that entire stretch, cheap Chinese factory goods suppressed global inflation — the hidden cushion that let central banks hike without fully breaking demand. That disinflationary tailwind is now reversing. At the same time tariffs are raising the cost of Chinese imports from the other direction. The squeeze is two-sided.

March CPI: 3.3%. Energy up 10.9%. Gasoline +21%. In 1973, an oil embargo spiked headline CPI. The Fed hiked. Oil didn't fall. The recession deepened. You can't cure a supply shock with rate hikes. Today's print is the same structure: exogenous energy spike (Iran war), contained core. Raising rates won't lower gasoline — it'll tighten credit in an economy already under tariff stress. Same trap. Different headline.

US sanctions no longer isolate rivals - they accelerate payment innovation. Every time Washington weaponizes dollar rails, counterparties invest in bilateral settlement, commodity barter, and non-SWIFT clearing. Coercion raises the ROI of alternatives, so sanctions slowly erode dollar plumbing even when they win headlines.

Markets don’t trade the GDP revision first. They trade the Treasury funding condition first. Core PCE and GDP are backward-looking and revisable; auctions clear in real time. The mechanism: when debt stock is large, financing pressure leads policy and pricing while macro prints confirm it later.

The tariff pause wasn't about the stock market crashing. It was about Treasury yields rising when they should have fallen. Those are different mechanisms — and the difference tells you exactly where the ceiling on US policy sits. Thread:

The tariff debate is entirely about economics. Almost no one is asking about the law. SCOTUS struck down IEEPA in February. The replacement authority is Section 122 of the Trade Act of 1974 — capped at 15%, time-limited to 150 days, and legally contested. The 150-day clock started February 20. It runs out around July 23. If Section 122 expires or fails legal challenge — what exactly holds the tariff regime together after that date?

Japan's 10-year government bond yield hit 2.43% this week — highest since 1997. Markets now price a BOJ rate hike this month at over 70%. That's a Japan bond story on the surface. Beneath it is the yen carry trade. Borrow yen near zero. Convert to dollars. Buy US equities, credit, global assets. When Japanese rates rise and the yen strengthens, that loan gets more expensive — forcing a simultaneous sell of whatever was bought with it. Markets are absorbing a tariff shock right now. They may also be absorbing something quieter: carry trade exits triggered not by trade policy, but because the borrowing math changed in Tokyo. These aren't the same seller. They produce the same output. The deeper version — sources, full argument — is in this week's Hard Money Report. Link in bio.

In August 1971, Nixon hit allies with a 10% import surcharge. Every economist called it protectionism. Four months later: Smithsonian Agreement. Currencies realigned. Surcharge dropped. The protectionism was a forcing function for monetary reform. April 9, 2025 — Liberation Day. 145% tariffs. Markets crashed. Six weeks later: 10% deal, Trump-Xi summit on the calendar. One year later, the mechanism is the same. Tariffs as leverage, not walls. The question was never whether they'd stay — it was what they were negotiating toward. The deeper version — sources, full argument — is in this week's Hard Money Report. Link in bio.

The trade war's next phase isn't tariffs — it's currency. At 104% on Chinese goods, the incentive to let the yuan weaken is overwhelming. Every 10% CNY depreciation offsets roughly 10 points of tariff cost for Chinese exporters. Beijing doesn't need to match tariff for tariff. It can devalue. The mechanism: trade restrictions create devaluation incentives. Devaluation partially neutralizes restrictions. The escalation continues — just on different terrain. The US has tariff tools. It has weaker tools for currency.
