Recorded in China, the episode features Matthew Klein, co-author of Trade Wars Are Class Wars, and Professor Ning Zhu, author of China's Guaranteed Bubble. The discussion explores the forces reshaping the world economy, including China's slowing property market, America's rising debt, trade imbalances, financial markets, globalisation and the evolving relationship between geopolitics and economics.
A major discussion begins when Kamath questions why investors continue lending to the US government at roughly 4% despite record levels of debt. He asks why US Treasuries remain among the world's safest assets as America's borrowing continues to increase. Klein attributes this confidence to expectations about future US growth and inflation, while Zhu argues that the reason is more straightforward: no other market provides the scale and liquidity required by global reserve managers.
When asked where yields could stand in ten years, Klein challenges market expectations, suggesting they could rise if AI-driven investment increases returns across riskier assets. He also cautions against assuming that ageing populations automatically lead to higher rates, noting that the research behind that argument largely comes from young, fast-growing societies rather than truly aged economies such as Japan. Zhu maintains that safety remains more important than yield and says the US continues to have no genuine competitor on that measure.
The conversation then turns to the future of the US dollar and China's efforts to internationalise the renminbi. Both economists agree that de-dollarisation requires a credible alternative rather than dissatisfaction with the existing system. They argue that neither the renminbi nor the euro has developed the deep and open capital markets required to become a major replacement.
Klein highlights what he describes as a counterintuitive development: dollar-backed stablecoins could further strengthen the dollar's global position by creating a faster and cheaper way to transact in dollars, even as discussions around de-dollarisation become more prominent. Zhu says exchange rates will remain the natural pressure valve for trade imbalances. He notes that the renminbi experienced a 30% devaluation over the past decade and has appreciated 10–15% since last summer, although he acknowledges that China's trading partners still consider the adjustment too slow.
The economists also challenge conventional assumptions about how markets respond to major events. Klein recalls how Japan's 1995 Kobe earthquake unexpectedly strengthened the yen rather than weakening it, showing that capital flows, liquidity and investor positioning can often have a greater influence than traditional economic expectations. The example reflects a wider argument that markets frequently behave differently from textbook predictions.
One of the episode's most significant discussions focuses on why inflation has not returned despite years of aggressive monetary stimulus. Zhu suggests that much of the liquidity created did not disappear but instead moved into asset prices, including US stocks and Chinese property before 2021. He links this trend to growing wealth inequality and its consequences for political polarisation.
Behavioural economics becomes a central theme as Zhu discusses his research into China's housing bubble. He explains how governments, developers and consumers gradually developed the belief that property prices could only move upward. Kamath connects the idea with India, where developers often argue that land prices never fall. Zhu says stronger property taxes are among the few effective measures to discourage the speculation that allows such beliefs to develop.
The discussion expands beyond China and the United States to a more fragmented global environment shaped by geopolitics, demographics and inequality. Both guests describe India as one of the world's most promising long-term growth stories while emphasising the importance of greater economic understanding as global interdependence changes.
The episode concludes with a focus on uncertainty and adaptability rather than prediction. When asked what could come next for China, the dollar and the global economy, Zhu offers the advice to "Embrace whatever comes," while stating that change is the only constant. The conversation highlights adaptability as a crucial factor in navigating future economic shifts.
