Chinese private portfolio equity outflows, though small compared to other Chinese outflows, are growing rapidly because of capital account liberalization and capital flight. Using granular stock-holding data on Qualified Domestic Institutional Investor (QDII) mutual funds, we identify a nascent financial channel of international transmission of Chinese monetary policy to world stocks. Event study analysis around monetary policy announcement days reveals that monetary policy tightening depresses returns of country equity indexes and individual U.S. stocks with QDII fund exposure relative to non-exposed stocks. The results are robust to controlling for the real transmission channel of Chinese monetary policy and other confounders. The effect is driven by smaller and less liquid firms, but not by China-concept stocks or those highly exposed to China’s macroeconomic shocks. We also find that the results are driven by household portfolio rebalancing from more to less risky assets following the announcement.

NON-TECHNICAL SUMMARY
FOCUS
This paper investigates the international financial transmission of China’s domestic monetary policies through private portfolio equity flows. Although Chinese private portfolio outflows remain relatively small, they are expected to expand as China pursues the internationalization of the Renminbi and seeks to mitigate pressures from a weakening U.S. dollar. The findings highlight an emerging financial channel through which China’s domestic policies increasingly shape international capital movements and global financial stability.
CONTRIBUTION
Using granular stock-holding data from China’s Qualified Domestic Institutional Investor (QDII) mutual funds, this paper uncovers a nascent financial channel through which Chinese monetary policy transmits internationally to global equities. To assess the impact of Chinese monetary policy changes, we conduct an event study around monetary policy announcement days, which occur at a higher frequency than portfolio rebalancing decisions. This research contributes to the literature on international monetary transmission and global shocks, expanding limited work on China’s role. It also deepens understanding of China’s macroeconomic influence, exchange rate management, and financial liberalization within the broader context of global financial integration.
FINDINGS
We find that, on monetary-tightening announcement days, country equity indexes and U.S. stocks held by QDII funds underperform comparable non-exposed stocks. This is robust to controls for real-economy channels and other confounders. The impact concentrates in smaller, less-liquid firms; it’s not driven by “China-concept” or macro-exposed stocks. Evidence indicates Chinese households rebalance from riskier to safer assets after tightening, revealing a nascent international financial channel. Interestingly, unlike other countries’ private equity outflows, China’s flows are largely retail-driven. As China continues to liberalize its capital outflows, understanding these dynamics will only become more important for policy makers.
