Trader’s remarks: Chinese stock markets have followed a crazy path in the last couple of years. A weakening outlook for Chinese growth and slip in China’s currency have combined to put pressure on other emerging economies. With emerging markets faltering and Chinese rebalancing incomplete, rich economies are left as the lone engine of economic growth. That is a worrying prospect. Rich-world governments have exceptionally little wriggle-room to act to boost up their economies. Interest rates are still at rock bottom, if not negative and debt and deficits remain at levels that would inhibit recession-busting spending policies.
