Nikhil Kamath Explores China's Housing Crisis, America's Debt and the Future of the Global Economy with Matthew Klein and Professor Ning Zhu

The world is asking bigger economic questions than it has in decades. Why hasn’t the world seen more inflation, despite over a decade of massive money-printing? Is the dollar still dominant because it’s the best currency—or simply because there’s no viable alternative? Is China’s property crash over — or is the bubble psychology still there?

Matthew Klein and Professor Ning Zhu with Nikhil Kamath on People by WTF

In the latest episode of People by WTF, Nikhil Kamath sits down with economist and author Matthew Klein, co-author of Trade Wars Are Class Wars, and Professor Ning Zhu, author of China’s Guaranteed Bubble. Recorded in China, the conversation moves beyond headlines to examine the forces reshaping the global economy—from China’s slowing property market and America’s growing debt to trade imbalances, financial markets and the future of globalisation.

One of the episode’s liveliest exchanges begins when Kamath questions why investors continue lending to the US government at roughly 4% despite record levels of debt. If America’s borrowing keeps growing, why does the world still treat US Treasuries as one of its safest assets? Klein points to confidence in future US growth and inflation; Zhu points to something simpler—no other market offers the scale and liquidity that reserve managers need. Asked where yields might be in ten years, Klein pushes back on market consensus, arguing they could actually rise if AI-driven investment lifts returns across riskier assets—and cautions against assuming an ageing population pushes rates up by default, since the research behind that claim comes largely from young, fast-growing societies rather than truly aged ones like Japan. Zhu’s answer stays simpler: safety still beats yield, and by that measure, the US has no real competitor.

The discussion naturally turns to the future of the US dollar and China’s ambition to internationalise the renminbi. Both economists agree de-dollarisation requires a credible alternative, not just dissatisfaction with the dollar — and argue neither the renminbi nor the euro has built the deep, open capital markets needed to become one. Klein points to a counterintuitive twist: dollar-backed stablecoins may be entrenching the dollar’s dominance further, offering a faster, cheaper way to transact in dollars even as de-dollarisation rhetoric grows louder. Zhu sees the exchange rate as the natural pressure valve for trade imbalances looking ahead—the renminbi, after a decade-long 30% devaluation, has already appreciated 10–15% since last summer, though he acknowledges China’s trading partners still see the adjustment as too slow.

The conversation also overturns 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, illustrating that capital flows, liquidity, and investor positioning often matter more than conventional economic logic. The example becomes a broader reminder that markets rarely behave as textbooks predict.

One of the episode’s more provocative moments comes when Kamath asks why inflation hasn’t returned despite years of aggressive monetary stimulus. Zhu offers a theory: much of that liquidity didn’t vanish; it flowed into asset prices instead — US stocks, Chinese property before 2021 — quietly building wealth inequality rather than showing up in the CPI, with consequences he links to today’s political polarisation.

Behavioural economics becomes a central theme. Drawing on his research into China’s housing bubble, Zhu explains how governments, developers and consumers gradually convinced themselves that property prices could only move in one direction—a pattern Kamath recognises instantly in India, where developers insist land prices never fall. Zhu argues stronger property taxes are one of the few real correctives, since they discourage the speculation that lets such beliefs take hold in the first place.

The discussion expands beyond China and the United States to examine a world becoming increasingly fragmented, where geopolitics, demographics and inequality are reshaping trade, investment and policymaking. Both guests describe India as one of the world’s most promising long-term growth stories while calling for greater economic understanding as global interdependence evolves.

The episode closes on a note of humility rather than prediction. Asked what comes next for China, the dollar and the global economy, Zhu offers a simple piece of advice, besides positing that change is the only constant: “Embrace whatever comes.” It is a fitting conclusion to a conversation that repeatedly argues that adaptability—not certainty—may prove the world’s most valuable economic advantage.

The episode explores not just what is changing in the global economy, but how those shifts could influence investment, business and policymaking in the years ahead. The episode is available now on YouTube, Spotify and all major podcast platforms.
