    Podcast Summary

    • Carry trade unwindingThe carry trade unwinding is a significant market event, but it's important to separate fact from fiction and avoid overdramatizing its potential impact. The size of the carry trade is often exaggerated, and not all yen-denominated assets are part of the carry trade.

      The carry trade, a financial transaction involving borrowing in lower yielding currencies and investing in higher yielding assets, has been a topic of concern in financial markets recently due to its unwinding. However, the conversation around the potential implications of this unwinding, which some suggested could lead to a financial crisis, has quickly faded as markets recovered. Hyun Sung Shin, economic advisor and head of research for the Bank for International Settlements, clarified on Odd Lots that the carry trade is a common practice in financial markets and its unwinding is not necessarily a cause for alarm. He explained that the size of the carry trade is often exaggerated, as not all yen-denominated assets are part of the carry trade. Overall, while the carry trade unwinding is a significant market event, it's important to separate fact from fiction and avoid overdramatizing its potential impact.

    • Carry Trade Impact on Financial MarketsThe carry trade, involving borrowing in low-interest currencies and investing in higher-yielding assets, contributes significantly to financial markets, with around $270B in yen borrowing through various channels. While much is for hedging, the risk of selling borrowed yen instead of parking in safe assets could cause instability.

      That the carry trade, which involves borrowing in a low-interest currency like the Japanese yen and investing in higher-yielding assets, was a significant factor in financial markets during a recent episode of market stress. However, the scale of this activity is larger than commonly perceived, with estimates suggesting around $270 billion in yen borrowing through both on-balance sheet and off-balance sheet transactions. The borrowing often takes place through inter-office accounts within foreign banking groups, but a significant portion occurs in the FX swap market, where parties exchange currencies with the agreement to reverse the transaction at a later date. While much of this activity is used for hedging purposes, there is a risk that some parties may choose to sell the borrowed yen instead of parking it in safe assets, potentially contributing to market instability. It's important to monitor the size and behavior of carry trade activities to better understand their impact on financial markets.

    • Foreign Exchange SwapsThe FXSWAP market, a $14 trillion market, plays a crucial role in managing currency risk for financial and non-financial institutions, enabling them to invest in assets of another currency regardless of their funding currency, and providing liquidity to emerging market exporters, thereby reducing currency constraints and expanding credit.

      The Foreign Exchange Swap (FXSWAP) market, which is around $14 trillion, plays a crucial role in hedging currency exposure for both financial and non-financial institutions. For non-financial institutions like importers or exporters, swaps help manage currency risk until the maturity of transactions. However, since the global financial crisis, financial uses of FXSWAPs have grown significantly, enabling institutions to invest in assets of another currency regardless of their funding currency. This global perspective on financial conditions is essential as it allows institutions to deploy funding in one currency and invest in another, expanding credit in the overall system. The FXSWAP market also provides additional liquidity for emerging market exporters seeking dollar funds, thereby reducing currency constraints and expanding credit. Overall, the FXSWAP market is a vital tool for managing currency risk and diversifying investments in today's global economy.

    • FX swap transactions during financial stressUnexpected changes in FX swap transactions during financial stress can occur despite minimal changes in swap basis, requiring careful consideration of risk management and loss mitigation strategies to prevent amplification and volatility

      During periods of financial stress, the direction of FX swap transactions can change, and borrowing yen instead of dollars can occur. This was evident during a mini crisis in July 2024, when the effects swap basis between the dollar and yen hardly moved despite the volatility in the currency market. Contrary to expectations, dealer banks continued providing liquidity, allowing the reversal of the move to happen easily. However, the broader equity market stress went beyond what could be explained by traditional carry trades alone. Instead, it's essential to consider how risk management and loss mitigation strategies can contribute to amplification and volatility. For instance, if a risk management rule is triggered, it could lead to position cuts, exacerbating market moves. The mini crisis of July 2024 was a reminder that the interplay of various market factors can lead to complex market dynamics.

    • Interconnected risks in financial marketsDuring market stress, interconnected risks in various financial markets can amplify losses and have far-reaching consequences. Improving transparency and risk management strategies is crucial to address these issues effectively.

      During times of market stress, interconnected risks in various financial markets can amplify losses and have far-reaching consequences. For instance, a firm might have one team engaged in a carry trade and another team invested in technology stocks, but if risk limits are triggered, the entire portfolio could be affected. The lack of transparency in FX swaps and the instigator of these transactions can also make it challenging to understand and mitigate these risks. The financial industry needs more refined data and a better understanding of interconnections between different markets to address these issues effectively. Overall, it's crucial to recognize the interconnected risks in various financial markets and work towards improving transparency and risk management strategies.

    • Market-based financial indicatorsIn the new market-based financial system, money flows to the most accommodative section and swap markets facilitate this fungibility. Keep track of market-based indicators for a better understanding of the financial landscape.

      Financial conditions, as measured by traditional indicators like interest rates and credit spreads, can be misleading in a world where money is easily swapped between currencies through non-bank channels. The global financial system has shifted from being bank-based to market-based since the Global Financial Crisis, and this has led to a greater emphasis on market-based indicators like FX and SWAP markets. In this new environment, money will flow to the most accommodative section of the money market, and the swap is the instrument that facilitates this fungibility. The carry trade, which involves borrowing in a low-interest-rate currency and investing in a high-interest-rate currency, is an example of how this works. Although the yen carry trade has normalized since it hit the headlines, it may re-emerge as market conditions change. It's essential to update our perspective on financial markets and keep track of the latest indicators to fully understand the current financial landscape.

    • Financial market factorsPolicymakers must consider factors beyond economic indicators, address procyclical margin variations, ensure adequate margins, and stay updated with financial system's evolving realities to prevent sharp market swings.

      The financial markets can be influenced by factors beyond traditional economic indicators, and policymakers must consider the bigger picture, including the structure of the financial system and the potential for amplification effects. The March 2020 episode with the treasury market stress highlighted the need to address procyclical margin variations and ensure that margins don't get eroded too thinly during good times to prevent sharp swings in the market. Additionally, there is a need for better data on emerging aggregates and a continual effort to stay updated with the financial system's evolving realities. While hindsight is 2020, the importance of considering the broader implications of financial market movements cannot be overstated.

    • Fed's rate cut during COVID-19The Fed's rate cut during COVID-19 was justifiable given the economic conditions, but identifying potential financial crises before they occur is a constant challenge for regulatory bodies

      While the sudden decision by the Federal Reserve to cut interest rates by 100 basis points during the height of the COVID-19 market turmoil in March 2020 may seem questionable in hindsight, it may have been justified based on the economic conditions at the time. The BIS emphasizes that extraordinary interventions should only be considered when markets are experiencing complete dysfunction and the flow of finance to real economic activity is suffering. Regarding the observation of speculative excess bubbles, the BIS acknowledges that while they have reliable measures in retrospect, it's an ongoing struggle to keep up with constantly changing markets and identify potential issues before they become crises. The BIS continues to refine its checklist and methods for identifying potential risks, but it's an ongoing process that requires constant effort and study.

    • Carry Trade and Market VolatilityThe carry trade's relationship to market volatility is complex and requires recognizing interconnectedness, distinguishing causality from correlation, and considering multiple sources of funding and liquidity.

      Understanding the complexities of global financial markets requires a nuanced perspective and recognition of interconnectedness. During a recent podcast episode, the topic of the carry trade and its relationship to market volatility was discussed. The speakers emphasized the importance of distinguishing causality from correlation, as well as recognizing the fungibility of money and the need for a global financial conditions index. The carry trade, which involves borrowing in low-interest-rate currencies to invest in higher-yielding assets, can be influenced by various factors, and the unwinding of this trade doesn't necessarily cause market volatility. Furthermore, the availability and cost of credit do not always align, and recognizing this interconnectedness can help make sense of seemingly disconnected market events. The speakers also discussed the importance of considering multiple sources of funding and liquidity when analyzing financial conditions. Overall, the conversation highlighted the importance of a holistic perspective when analyzing financial markets and the need for tools like a global financial conditions index to help make sense of complex market dynamics.

      Adam Tooze on the Big Misconceptions of the Chinese Economy

      Adam Tooze on the Big Misconceptions of the Chinese Economy

      One of the big buzzwords over the last year or so has been "overcapacity." There's a constant line of argument that China is unfairly flooding the world with unprofitable goods and creating huge, unsustainable imbalances. Western countries, particularly the US (but also Europe), have responded by raising tariffs and engaging in domestic industrial policy in order to compete. But is the strategy sound? Are the basic premises of the problem correct? On this episode of the podcast, we speak with Columbia Professor Adam Tooze, the author of several books, as well as the popular Chartbook newsletter. He argues that the overcapacity framing is misguided, and that the US may be making a mistake putting its chips down on an industrial revival. He talks us through some of the actual weaknesses of the Chinese model, as well as its global political reverberations.

      US Trade Rep Katherine Tai Describes the New Era of Globalization

      US Trade Rep Katherine Tai Describes the New Era of Globalization

      One of the rare areas of bipartisan consensus in the US right now, is on the need to change our trading relationship with China. Former President Donald Trump started a process of putting tariffs on Chinese goods and limiting the export of certain key technologies. This has only expanded under the Biden administration, with expanded restrictions on things like electric vehicles, solar panels, and semiconductors. So what's the thinking behind this drive? What are the goals and what are the risks? On this episode we speak with the United States Trade Representative Katherine Tai. Ambassador Tai describes what she sees as a rethink, or a new version of, globalization. She explains the new worker-centric priorities, how trade fits into domestic investments, and what a healthy version of international economic relations actually looks like.

      The Booming Crypto Use Case That's Happening Right Now

      The Booming Crypto Use Case That's Happening Right Now

      Pretty much since the moment that cryptocurrencies came into existence, there's been a chorus of skeptics who argue that they solve no real world use cases, except for gambling and speculation. For a while, there was a lot of hype about things like Web3 or DeFi, but for the most part, these still remain in the realm of pure speculation and gambling. And so, the ultimate use case for crypto remains elusive. Our guest on this episode argues otherwise. He thinks that stablecoins, such as Circle or Paxos, which are backed by actual dollar instruments in regulated institutions running on public blockchains (like Ethereum or Solana) are solving a genuine problem in transmitting money, beyond just speculating on other cryptocurrencies. Austin Campbell is an adjunct professor at Columbia Business School and the founder of Zero Knowledge Consulting. He also comes with a long resume at both crypto and legacy financial institutions. He explains why stablecoins are having a moment and explains the problems they currently solve (particularly internationally) and why legacy payments infrastructure is unlikely to serve the same needs.

      How Hedge Funds Discover the Next Superstar Trader

      How Hedge Funds Discover the Next Superstar Trader

      One of the problems in investing or trading is that — to use a common disclaimer — past results are no guarantee of future success. Someone can have a great track record in their stock picks, but maybe they just got lucky. Or maybe they were particularly well-dialed into one market regime that inevitably shifts. Or maybe they're actually just better than other traders. For multi-strategy hedge funds or "pod shops," there's an ongoing battle to hire or train the next great portfolio manager. But how can managers tell who is actually good and who isn't? On this episode of the podcast, we speak with Joe Peta, who was previously the head of performance analytics at Point72 Asset Management and has had a long career in the trading world. He's also an avid fan of sports gambling, and the author of the recent book, Moneyball for the Money Set, which attempts to take some of the talent analytical principles that originated in Major League Baseball and apply them to evaluating portfolio managers. He talks us through the traditional approach funds use to find or create superstars, and how these approaches can be improved upon using more rigorous, quantitative methods.

      The Black Hole of Private Credit That's Swallowing the Economy

      The Black Hole of Private Credit That's Swallowing the Economy

      There's been a lot of talk about private credit in recent years. The market has exploded in size, and there are worries that it could be a bubble that eventually bursts and sparks disaster. But there are other negative effects from private credit that might already be happening. In a new paper called "The Credit Markets Go Dark," co-authors Harvard Law School professor Jared Ellias and Duke University School of Law professor Elisabeth de Fontenay argue that the $1.5 trillion market for private credit is already having a big impact on the economy — and not in a good way. They say that the rise of private credit marks a seismic change for corporate governance and dynamism.

      Adam Posen on the Dangers of Jerome Powell's 'Rifle Shot' Jackson Hole Speech

      Last week at Jackson Hole, Federal Reserve Chair Jerome Powell delivered a short and powerful speech indicating that it's time for a policy pivot. The goal now, from his perspective, is to prevent further deterioration of the US labor market. His speech didn't delve much into theory or nuance. In this episode, we speak with Peterson Institute President, Adam Posen, who found the speech unsatisfying. He argues that the state of the labor market, while cooling, didn't merit a "rifle shot" approach, such as the one Powell delivered. He explains his concerns and how he sees the risks materializing from here.

      A New Way for the Fed to Fight a Market Crisis

      A New Way for the Fed to Fight a Market Crisis

      When the Treasury market broke in March 2020, the Federal Reserve intervened in extraordinary fashion. It purchased more than $1 trillion worth of Treasury securities in that month alone. Superficially, this looked a lot like the Quantitative Easing that we came to know during the GFC. But it's purpose was different. This wasn't about depressing the yield curve or providing a form of strong forward guidance. Instead, it was the Fed taking on a role of the "market maker of last resort," so to speak. And yet, despite the different goals, the two different operations look the same and are carried out by the same officials (the members of the FOMC). This creates confusion, cost, and can create a situation where it looks like the Fed is working against itself. On this episode of the podcast, which was recorded in Jackson Hole at the Kansas City Fed's annual Economic Symposium, we speak with University of Chicago Booth professor, Anil Kashyap. He presented a paper at the conference proposing a separate tool within the Fed that can handle balance sheet operations for financial stability. We discussed his proposal along with broader questions about the transmission of monetary policy.
