Episode 024: Crisis in Europe

Introduction The European crisis that Marvin Barth and Mark Farrington have long warned of appears to have begun…while Marvin and Mark were focused on the “mother of all resolution windows” in the US ahead of the US midterm elections, the AI race, Fed credibility, and geopolitics. Mark and Marvin review the thesis for why Europe was a growing pile of dry tinder waiting for a spark before turning to what events and forces coalesced to create that spark. They then discuss how Europe’s increasing self-isolation, its deep and difficult to reconcile problems, and the loss of a credible German…

Episode 023: Noise awaiting signal
Introduction In this episode of Thematic Edge, Marvin Barth and Mark Farrington revisit the “resolution window” stretching from the summer through the US midterm elections examine what market signals we’ve gleaned so far. They assess the latest inflation data and central bank decisions, the changing shape of the US Treasury curve, Scott Bessent’s management of the bond market and the strength of corporate earnings. They also examine the growing anxiety surrounding AI, from regulation to US-China competition to the rapidly expansion of financing needs for the investment boom. They note that…

Episode 022: Competition for capital
Introduction In this episode of Thematic Edge , Marvin Barth and Mark Farrington reunite to examine what is really driving the rise in sovereign bond yields around the world. Their central argument is that the move is bigger than fiscal policy or any single government: capital is becoming more expensive as investment demand rises, global savings come under pressure and central banks struggle to rebuild credibility. The conversation moves from Kevin Warsh’s first months at the Federal Reserve and the bond market response to the Iran war, to Treasury buybacks, FX intervention and the…

Episode 021: Alexander Stahel & Russia's endgame
Introduction In this episode of The Thematic Edge , Marvin Barth and Mark Farrington speak with Alexander Stahel, Chief Investment Officer of Burggraben Holdings and author of The Commodity Compass , about an emerging crisis in global petroleum product markets. The conversation examines how the war with Iran, Ukraine’s increasingly sophisticated attacks on Russian refining infrastructure and China’s focus on domestic energy security have combined to create severe pressure in diesel, gasoline and jet fuel markets. They explore how Ukraine’s strategy has moved beyond damaging Russian energy…

Episode 020: Sintra, forward guidance & the dollar
In episode 020 of Thematic Edge , Marvin Barth and Mark Farrington consider the broader implications of the European Central Bank’s retreat in Sintra, Portugal where there seemed to be shift in global central bank philosophy led by new Fed Chairman Kevin Warsh and his drive to end the practice of forward guidance. Marvin and Mark discuss what the end of forward guidance means for near-term Fed policy and markets, and how Sintra may have helped Chairman Warsh push a rate hike back home. They also discuss how forward guidance and increasingly activist monetary policy changed market behavior —…

Episode 019: "Macro Crypto" with Arthur Hayes
In this episode of Thematic Edge, Marvin Barth and Mark Farrington sit down with Arthur Hayes to explore one of the most important questions in crypto today: what ultimately gives Bitcoin value? While all three agree that liquidity, monetary policy and sovereign incentives shape markets, they discuss their differences in evaluating fundamental value. Arthur Hayes is one of the most influential figures in the history of cryptocurrency. He co-founded BitMEX, once the world’s largest crypto derivatives exchange, pioneered the perpetual swap contract that now dominates crypto trading, and helped…

Episode 018: Fed regime change
In this episode of Thematic Edge, Marvin Barth and Mark Farrington examine whether central banks are finally being forced to confront a changing inflation regime. They argue that policymakers have been too willing to look through supply shocks, too focused on protecting growth, and too slow to respond to rising inflation expectations. The discussion centers on the arrival of Fed Chairman Kevin Warsh and whether his appointment signals a broader shift in central banking philosophy around the world. Key themes • Why central banks may have misread the inflationary consequences of the Hormuz…

Episode 017: "Mark"ing to market: Iran & China views
In this episode of Thematic Edge , Marvin and Mark examine the evolving Iran conflict, the shift in US strategic thinking, and the emerging logic of trying to “make business not war” amid Global bifurcation . The discussion explores why the expected energy shock hasn’t been as severe as projected, how the US has pivoted toward a maritime containment strategy, and why the US has shifted its focus to controlling global choke points. Marvin and Mark also examine China’s hoarding strategy across commodities, reserves, collateral, and logistics, arguing that Beijing has spent years building…

Episode 016: Fed independence
In this special episode of Thematic Edge, recorded around the Hoover Institution Monetary Policy Conference at Stanford University, Marvin Barth explores why the greatest risks to Federal Reserve independence may be the Fed’s own policy errors, institutional overconfidence, and expanding mandate. Through conversations with leading economists, former policymakers, and Fed officials, the discussion examines the growing tension between fiscal sustainability, monetary policy, bank regulation, and political control. Key themes * Why central bank independence ultimately depends on fiscal…

Episode 015: US & Fed outlook with Danny Dayan
In this episode of Thematic Edge , Marvin Barth and Mark Farrington are joined by Danny Dayen for a wide ranging debate on inflation, monetary policy, and whether the Federal Reserve is now behind the curve. The discussion begins from an unusual point of agreement. Both Marvin and Danny argue the Fed has committed a sequence of policy errors that risks overheating the US economy and reigniting inflation. But from there, important differences emerge, especially over the likely conduct of a Warsh Fed, the role of balance sheet policy, and whether supply shocks now require an explicitly hawkish…

Episode 014: Iran blockade
A detailed and at times sharply contested discussion on the strategic direction of the Iran conflict following the collapse of US-Iran peace talks and what it means for markets (recorded at noon London time on 13 April). In this episode, Mark and I analyse the shift from an historically intense air campaign to a US-led maritime interdiction strategy. While we both agree that the US is attempting a novel “sovereignty-denial” strategy for regime change, we differ on how much control the US will have over the intensity of the conflict from here. We discuss how the US is shifting…

Episode 013: Iran strikes credit with Zoso Davies
This week Mark Farrington and I are joined by Zoso Davies , formerly Managing Director in European Investment Grade Credit Research at Barclays, where he spent over 15 years analysing major credit cycles including the European sovereign crisis, Brexit, and COVID. Now at a leading London based hedge fund and author of Macro Credit Thinking , Zoso brings a rare combination of top down macro perspective and deep credit market expertise. The discussion reframes how to think about credit risk as markets from stable but nervous about private credit to the realization that Iran-related disruptions…

Episode 012: Doomberg - Strategic implications of the Iran war
A sharp and wide-ranging discussion on the strategic consequences of the Iran war. In this episode, Doomberg joins Marvin Barth and Mark Farrington to unpack why markets have remained surprisingly calm despite escalating violence in the Middle East, what may be coming next, and what the long-term, strategic consequences of this conflict are likely to be. The conversation digs deep into the structure of the global energy system. Key themes: * Market resilience despite conflict, supported by inventories, spare capacity, and supply leakage * Escalation risk and the limits of rerouting flows…

Episode 011: Iran implications with Erik @YWR
How could the Iran conflict reshape global markets, China risk premiums and emerging market capital flows? Marvin Barth and Erik @YWR discuss geopolitics, uncertainty and the investment implications of a changing global order. In this episode, they explore whether a US-aligned Middle East could reduce geopolitical risk, why emerging markets may benefit from shifting capital flows, and whether China’s equity story changes if Taiwan risk declines. The conversation also examines Europe’s strategic positioning, the future of the dollar, and the broader macro consequences of global power…

Episode 010: Forest fire insurance
Forest Fire Insurance explores how risk truly builds in financial systems and why volatility is not the enemy it is often portrayed to be. Marvin Barth and Mark Farrington are joined by David Dredge, CIO of Convex Strategies, to unpack the idea of self organised criticality in markets using the forest fire analogy. The discussion ranges from leverage, correlation and contagion to the failures of Sharpe ratio thinking and the dangers of suppressing volatility. The conversation moves through convexity, tail risk, demographic decline, central bank policy and the growing fragility of the global…

Episode 009: Trump 2.1 shock
Unfortunately, the audio for this episode was terrible, so in addition to the time-stamped table of contents, a full, edited transcript is included below. In this episode, Marvin Barth and Mark Farrington reflect on a sequence of events that together signal a decisive shift in US strategy, from Venezuela to Greenland, and from emerging markets to monetary policy. They examine how recent US actions have reasserted strategic deterrence, clarified a new Western Hemisphere doctrine, and forced allies and adversaries alike to confront an uncomfortable reality. Whether welcomed or resented,…

Episode 008: Nigeria in focus
Nigeria is the largest economy and population in Africa, is abundant in natural resources, is an emergent cultural and technology center, and increasingly a regional manufacturing hub. Senator Ede Dafinone of Delta Central State (the main oil-producing region) explains the reforms of President Tinubu, the vast potential opportunities they may release, and how this lynchpin of Africa can navigate strategic competition between the US and China. 0:33 Why Nigeria merits your attention. 2:40 Who is Senator Ede Dafinone of Delta Central State? 6:19 The basis of Nigeria’s cooperation with US…

Making sense of Venezuela with David Kilcullen
The Thematic Edge opens 2026 with its first guest, David Kilcullen , retired Australian Army colonel, intellectual architect of both the “Surge” in Iraq and Afghanistan, and the world’s foremost authority on counterinsurgency. Colonel Kilcullen helps us make sense of what happened in Venezuela on 5 January and what to expect going forward. The discussion is structured around three questions that matter for markets. * First, what actually happened operationally, and what it reveals about escalation control, deterrence, and the limits of legacy air defence systems. * Second, what the episode…

Episode 006: Fed reform & US National Security Strategy
After a brief hiatus, the Thematic Edge is back! In the first half of this week’s episode, Mark queries me on Fed reform, a consistent theme of senior Trump officials that hasn’t received sufficient attention given its immense implications: what do they want to do and what can they do without Congress. In the second half we switch roles as I pull from Mark the real international relations implications of the abrupt turn in the latest US National Security Strategy paper. 0:00 Intro 2:23 Who will be the next Fed chairman? 3:23 Fed reform and financial deregulation is more important than low…

Episode 005: Forward guidance’s end
A very lively discussion this week that goes on a bit longer than usual as Mark & I get into a disagreement over the implications of Chinese gold-backed stablecoins. But before the fireworks, Mark & I review what President Trump achieved at ASEAN and APEC, how his earlier successes set him up for it, and what it means for Global bifurcation ; then we fire both barrels at the failure that has been central bank forward guidance and our prediction (hope?) that this travesty is about to meet it well deserved, but likely messy, end as fundamentals expose the fundamental errors in central banks’…

Episode 004: Officialdom grudgingly accepts stronger data
This week, Mark Farrington and I discuss what I learned from the semiannual World Bank-IMF meetings last week in Washington. Where do both policymakers’ and markets’ center of gravity lie? 0:00 Introduction: Impressions of World Bank-IMF meetings 2:25 IMF’s forecasts and embedded biases 4:08 Market participants’ views 6:13 Benchmarked managers more consensus than absolute-return managers 9:14 Strongest pushback on my views?

Episode 003: Good & bad government interventions
This week Mark and I discuss how “we’re all state capitalists now” but that both new Japanese Prime Minister Takaichi and US President Trump make an error when they try to include central banks in that effort. We discuss what markets are missing — inflation — and how that’s likely to be a key risk theme for 2026, and we touch upon whether the current equity boom is Dot.com 2.0, or something different. 0:07 The message of new Japanese Prime Minister Takaichi and what it means for Japan and the yen. 6:23 We’re all state capitalists now, but where do governments need to draw the line. 12:43 Can…

Episode 002: The Fed fumbles, BoJ pauses, & "dollar gamma" awaits
Mark and I covered a lot in this episode. We start with a quick recap of the Bank of Japan meeting Friday and the Federal Reserve meeting two days earlier. But we spend most of our time discussing a new piece by Mark, Dollar upside gamma: Systemic pressures , that mostly aligns with my long-standing views but raises both some critical differences and questions about the future. 0:00 Intro 1:18 The Bank of Japan pauses but October is live for another rate hike. 4:53 Mark calls 25 and done for the Fed; Marvin thinks it was a Train wreck , a clear policy error that raises the risks that they…

Episode 001: Introducing the Thematic Edge
Mark Farrington of the Global Watchtower and I have kicked off our own podcast on the Themes driving markets. Mark was practicing thematic investing as a portfolio manager long before it became a “thing” and a thematic approach to analysis of the global political economy has been my modus operandi for a quarter century. Mark and I have been debating markets for over twenty years and thought we’d bring that debate into the public. In this, our first episode we talk about the shifting sands of geopolitics in the wake of China’s Shanghai Cooperation Organization meetings, what it means for the…
