“President Trump ruffled feathers by criticising the Fed”

The S&P 500 Index experienced one of its worst Octobers since 1928, according to S&P Dow Jones Indices. Historically, the worst-performing Octobers for the S&P 500 Index have been followed by negative Novembers, although most of these were subsequently followed by positive Decembers. Over October as a whole, the S&P 500 Index fell by 6.9% while the Dow Jones Industrial Average Index fell by 5.1%. Technology-related companies fared particularly badly during the month, and the Nasdaq Index dropped by 9.2%. Sentiment was rattled by lacklustre third-quarter earnings releases from prominent companies, including Amazon, Google parent company Alphabet, Caterpillar and 3M, although investors drew some encouragement from strong third-quarter reports from Morgan Stanley, JPMorgan Chase, Citigroup and UnitedHealth.

Having grown at an annualised rate of 4.2% in the second quarter of 2018, the US economy expanded by 3.5% during the third quarter, underpinned by consumer and government spending. The International Monetary Fund (IMF)  downgraded its forecast for economic growth in the US next year from 2.7% to 2.5%. Elsewhere, President Trump ruffled feathers by criticising the Federal Reserve’s (Fed’s) tightening monetary policy, saying: “The Fed is doing what they think is necessary, but I don’t like what they’re doing … we don’t have to go as fast”.

The rate of unemployment fell from 3.9% in August to 3.7% in September to reach its lowest level since 1969. However, the US economy created only 134,000 jobs during September, compared with a 12-month average of 201,000 per month, although this could be attributable in part to the impact of Hurricane Florence. Annualised growth in average hourly earnings moderated from 2.9% in August to 2.8% in September.

Having previously reached an agreement with Mexico in August, the US finally settled a trade deal with Canada. The new deal – The United States-Mexico-Canada Agreement (USCMA) – will replace the North American Free Trade Agreement (Nafta) and will govern almost US$1.2 trillion in trade. Despite this, according to the IMF, the trade war between the US and China risks making the world a “poorer and more dangerous place”.
