This paper investigates the relationship between foreign private demand for treasuries and yield curves. By leveraging the forced rebalancing of the largest pension fund, I show that large foreign investors transmit foreign stock market shocks to U.S. bond markets. I find that a one-standard-deviation change in pension fund flows, approximately 3.6 billion dollars, leads to a monthly reduction of at least 4-5 basis points in U.S. yields. These findings highlight the role of foreign private investors as significant marginal investors. Similar effects are observed in the UK Gilt market.

The exchange-traded fund (ETF) market has become the most important recent development in financial markets. I show that the ETF network — the linkages between ETFs based on portfolio weights — catalyzes the propagation of price dislocations, the gaps between prices and fundamental values. Arbitrage activity induces price dislocations in connected ETFs, followed by responses in returns and subsequent reversals with an effect of 3–7% per year. While own fund flows create price pressure, bundled flows from neighboring funds can exert stronger price pressure in the opposite direction. This channel partially explains how price dislocations naturally arise in the ETF market.

Although real integration conceptually plays an important role for the comovement of international equity markets, documenting this link empirically has proven challenging. We construct a new dataset of theory-guided, relevant measures of bilateral trade in final and intermediate goods and services. With these measures, we provide evidence of a strong link between changes in real integration – in particular global value chains – and equity market comovement. This also holds when controlling for financial openness and other factors that could confound the role of real openness. These results suggest that supply chain disruptions, for instance due to political tensions and the COVID-19 crisis, might also affect the interconnections between stock markets via rippling through the global production network.
