To begin delving into the recent out-performance of the US stock market relative to its international peers, we need to reflect on the global fiscal and monetary response to the last crisis. After the great financial recession of 2008/2009, the main driver of stock market performance was the combined reduction of interest rates by the world’s largest central banks. When rate cuts failed to stimulate sufficient economic growth – and conscious of the failure of monetary largesse to stimulate the Japanese economy – the Federal Reserve embarked on successive rounds of ‘experimental’ quantitative easing. The US government also played its part, introducing the Troubled Asset Relief Program – TARP. Despite these substantial interventions, the velocity of circulation of money supply plummeted: and, although it had met elements of its dual-mandate (stable prices and full employment), the Fed remained concerned that whilst unemployment declined, average earnings stubbornly refused to rise.

Eventually, the US economy began to grow and, after almost a decade, the Federal Reserve, cautiously attempted to reverse the temporary, emergency measures it had been forced to adopt. It was helped by the election of a new president who, during his election campaign, had pledged to cut taxes and impose tariffs on imported goods which he believed were being dumped on the US market.

Europe and Japan, meanwhile, struggled to gain economic traction, the overhang of debt more than offsetting the even lower level of interest rates in these markets. Emerging markets, which had recovered from the crisis of 1998 but adopted fiscal rectitude in the process, now resorted to debt in order to maintain growth. They had room to maneuver, having deleveraged for more than a decade, but the specter of a trade war with the US has made them vulnerable to any strengthening of the reserve currency. They need to raise interest rates, by more than is required to control domestic inflation, in order to defend against capital flight.

In light of these developments, the recent divergence between developed and emerging markets – and especially the outperformance of US stocks – is understandable. US rates are rising, elsewhere in developed markets they are generally not; added to which, US tariffs are biting, especially in mercantilist economies which have relied, for so many years, on exporting to the ‘buyer of last resort’ – namely the US. Nonetheless, the chart below shows that divergence has occurred quite frequently over the past 15 years, this phenomenon is likely to be temporary: –
