--- title: "Macro FAQ" description: "Questions and answers on monetary plumbing, interest rates, currency dynamics, and the structural shifts in the global financial system." updated: 2026-10-03 author: "Philipp D. Dubach" canonical_url: "https://philippdubach.com/faq/macro/" source_url: "https://philippdubach.com/faq/macro/index.md" --- # Macro FAQ *Philipp D. Dubach · Updated October 3, 2026* --- Pulled from posts in the Macro category, newest first. Each answer reads as a citable claim and links back to the source post for the chart data, the footnoted derivation, or the broader thesis it fits inside. The framing is structural, not cyclical. Macro here means treating the dollar system as a plumbing problem first and a narrative second. Pozsar's Bretton Woods III as a working framework. Japan's $5T external position as a balance-sheet constraint. The $12.6T US repo market as the actual transmission channel. Europe's $24T payment-infrastructure realignment as an arbitrage trade dressed up as sovereignty. Recurring questions probe the levels-versus-rates problem (why falling inflation rates don't help when price levels are still elevated), the dual-mandate tension under structural shocks, middle-power realism as the new geopolitical default, and Britain's strategic limbo as a worked example of post-Brexit drift. Answers cite specific actors: Pozsar, Stewart, Thaler, named central bankers, named bond-market participants. Not aggregated "experts say." The default move is follow the balance sheet, not the press release. ## Frequently Asked Questions ### What is John Cochrane’s explanation of inflation? Cochrane links inflation to the fiscal backing of government liabilities. In his framework, prices can rise when nominal claims increase without a corresponding increase in expected future primary surpluses, or when expectations of that backing deteriorate. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### What is the fiscal theory of the price level? The fiscal theory of the price level relates the real value of nominal government liabilities to the expected present value of future primary surpluses: taxes minus noninterest spending. Its causal predictions depend on assumptions about fiscal and monetary policy. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### Does government debt cause inflation? More government debt does not mechanically produce inflation. In Cochrane’s framework, expected fiscal backing matters: borrowing can avoid inflation if people expect sufficient future surpluses, while a loss of confidence in that backing can affect prices even without new borrowing. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### Why do prices stay high when inflation falls? Falling inflation means prices are rising more slowly; it does not mean the price level is falling. A temporary inflation burst can therefore leave a permanently higher price level. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### Does John Cochrane support raising interest rates to fight inflation? Yes. In this lecture Cochrane supports raising rates in response to inflation. He questions how models account for the higher government interest costs and the accompanying fiscal response. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### Does AI investment cause inflation? AI investment can increase demand before new productive capacity arrives. Its economy-wide inflation effects depend on supply constraints and policy responses; private borrowing is not equivalent to unbacked government transfers. From [John Cochrane’s Lesson on Inflation](https://philippdubach.com/posts/john-cochranes-lesson-on-inflation/). ### What was the Fable 5 AI kill switch? On June 12, 2026, a US export-control directive required Anthropic to suspend Fable 5 and Mythos 5 for foreign nationals. Anthropic could not check nationality in real time, so it disabled the models worldwide. Access remained off through June 21. I treat this as the first clear use of an AI 'kill switch'. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### Why did Anthropic suspend Fable 5 and Mythos 5? A US export-control order required the suspension after the government cited national security and a claimed jailbreak. A jailbreak uses prompts to bypass a model's safeguards. Anthropic disputed the basis. It called the flaw a 'narrow, non-universal jailbreak' available from other models. The company complied because it could not screen users by nationality in real time. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### What was the AI Diffusion Rule, and why was it rescinded? The January 2025 US rule divided countries into three tiers for access to AI computing power. It placed European Union members in two different tiers. The government rescinded it in May 2025. The official notice said the rule had 'downgraded' allies to second-tier status. Allied access was therefore a discretionary privilege. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### Is Europe in economic decline compared with the US? On living standards, mostly no. Paul Krugman argued that much of the measured productivity decline came from price-index methods. A price index tracks changes in prices over time. The median living-standard gap remained roughly stable. The strategic problem is different: Europe uses frontier technology that it neither builds nor controls. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### What does European tech sovereignty mean? It means Europe can control essential chips, cloud services, AI models, data, and infrastructure without revocable dependence on foreign providers. The June 2026 European Union proposals included Chips Act 2.0 and the Cloud and AI Development Act. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### Why does ASML matter for European technology sovereignty? ASML is the only maker of extreme-ultraviolet (EUV) lithography systems. Chipmakers use these machines to produce leading-edge chips. ASML is therefore Europe's strongest technology chokepoint. Yet Europe still depends on foreign graphics processors, design software, cloud services, and frontier models. One chokepoint does not create autonomy. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### What is weaponised interdependence? Henry Farrell and Abraham Newman use this term for power created by control of economic networks. When an economy relies on a few hubs, a hub owner can cut off downstream users. They call this the chokepoint effect. The US-controlled AI stack of chips, cloud services, and models fits that pattern. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### Do open-weight models such as DeepSeek bypass US export controls? Partly. Open weights are model parameters that users can download and run. They are difficult to embargo once distributed. However, cloud services, application programming interfaces, and advanced chips cannot be downloaded with the model. These dependencies preserve the chokepoint. From [Krugman, Fable 5, and Europe in Decline?](https://philippdubach.com/posts/krugman-fable5-europe-decline/). ### Why does the economy feel bad when inflation is down? The economy feels bad because people experience price levels, not rates of change. Inflation fell from 9% to 2.4%, but cumulative prices rose roughly 25% since 2020, with groceries up 29.4% and housing affordability at its lowest since the 1980s. Economists celebrate the rate normalizing; consumers live with the permanent level shift. This levels-vs-rates disconnect is the structural explanation for the vibecession. From [People Live in Levels, Not Rates](https://philippdubach.com/posts/people-live-in-levels-not-rates/). ### What is the levels-vs-rates problem in economics? The levels-vs-rates problem describes a disconnect between how economists measure inflation (year-over-year rate of change) and how consumers experience it (cumulative price level). Inflation falling to 2.4% means prices are rising slowly again. It does not mean the 25% cumulative increase since 2020 reverses. A grocery bill that cost $150 in 2020 costs $194 today and will never cost $150 again. From [People Live in Levels, Not Rates](https://philippdubach.com/posts/people-live-in-levels-not-rates/). ### What did Jon Stewart say about economics to Richard Thaler? On February 4, 2026, Stewart hosted Nobel laureate Thaler on 'The Weekly Show' to discuss behavioral economics. In the conversation Stewart argued, in his own framing, that economics functions to maximise shareholder value and characterised nudge theory as inadequate for systemic problems. He then sketched a market-based mechanism for carbon mitigation that, as several economists noted publicly afterward, resembled the carbon tax Thaler had outlined moments earlier. The episode generated public commentary from economists including Jason Furman and Jerusalem Demsas. From [People Live in Levels, Not Rates](https://philippdubach.com/posts/people-live-in-levels-not-rates/). ### What is vibepression and how does it relate to the vibecession? Vibepression is a term coined by Charles Schwab's Kevin Gordon in December 2025 to describe the deepening of the vibecession, a concept Kyla Scanlon introduced in June 2022. As of February 2026, the University of Michigan consumer sentiment index sits at 57.3, the 3rd percentile of its historical range, despite GDP growth of 4.4% and unemployment of 4.3%. The vibecession never resolved; it got a bleaker name. From [People Live in Levels, Not Rates](https://philippdubach.com/posts/people-live-in-levels-not-rates/). ### Are real wages outpacing inflation in 2026? In aggregate, yes, since June 2023. But the distribution is K-shaped: high earners held 4.5% wage growth while the bottom quartile fell from 7.5% to roughly 3.5%. The Economic Policy Institute reported in February 2026 that low-wage workers' real wages actually declined in 2025, reversing pandemic-era compression that had closed up to one-third of the post-1979 wage gap. From [People Live in Levels, Not Rates](https://philippdubach.com/posts/people-live-in-levels-not-rates/). ### Will prices go back to pre-pandemic levels? No. Prices will not return to pre-pandemic levels. Cumulative CPI is up roughly 25% since early 2020, with food-at-home up 29.4% and housing costs up 30-45%. Reversing this would require sustained deflation, which central banks actively prevent because falling price levels cause recessions. The inflation rate has normalized at 2.4%, but the level shift is permanent.
