This paper studies the transmission of monetary policy to the stock market through investors’ discount factors. To isolate this channel, we investigate the effect of US monetary policy surprises on the ratio of prices of the same stock listed simultaneously in Hong Kong and Mainland China, and thereby control for revisions in cash-flow expectations. We find this channel to be strong and asymmetric, with the effect driven by surprise monetary policy interest rate cuts. A 100 basis point surprise cut results in a 30 basis point increase in the ratio of stock prices over 5 days. These results suggest significant slow-moving reductions in stock market risk premia following accommodating monetary policy surprises.

This paper examines whether China’s switch back and forth from fixed to floating exchange rates in 2005 and 2008 changed the contribution to stock price discovery by foreign and domestic investors. During that time, mainland investors could only trade the RMB-denominated A-shares in the domestic Shanghai and Shenzhen markets, while the dual-listed HKD-denominated H-shares were available only to overseas investors. Using intraday data on overlapping trading hours, we find that the switch from a fixed rate to managed floating in July 2005 increased the H-shares’ contribution to price discovery; while the exchange rate regime reversal in July 2008 allowed the domestic stocks to regain their dominance in information shares. These results imply that, in a market subject to restrictions on capital flows, a flexible exchange rate regime increases the propensity of investors to trade foreign-issued stocks to speculate on the RMB exchange rate, which raises overseas investors’ contribution to price discovery.

This paper assesses the impact of the recent financial reforms in China. Following the country’s accession to the World Trade Organization, financial liberalisation has picked up considerable momentum. Measures introduced encompass deregulation in the banking sector and refinements in various financial markets, as well as allowing more freedom for Chinese and foreign investors to participate and interact domestically and overseas. Compared to other studies on financial liberalisation, this study focuses on a relatively narrower aspect of financial reforms namely, the impact on stock market liquidity. Using a panel data set drawn from the Shanghai stock market, we find a positive and significant liquidity impact associated with the recent round of measures, which reflects not only an improvement in capital allocation efficiency in China’s equity market but, from a financial stability point of view, also a reduction in its vulnerability. The finding also provides evidence on one of the important channels in which financial liberalisation can be transformed into economic growth over time.
