South Africa's rand retreats

South Africa's rand weakened on Friday as the emergence of a fresh source of tension between the United States and China after Beijing moved to impose a new security law on Hong Kong hurt demand for currencies seen as higher risk.

The stock market also slipped as further strains in the Sino-US relationship offset optimism over a global economic recovery from the coronavirus. At 1645 GMT, the rand was 0.64% weaker at 17.7220 per dollar, having rallied to 17.5100 in the previous session, its highest since March 27.

The Johannesburg Stock Exchange (JSE) followed the main global markets and shed the last few days' gains, with the benchmark FTSE/JSE all-share index losing 1.7% to end the week at 50,156 points.

The top 40 companies' index fell 1.68% to close the week's trading at 46,441 points.

Bonds weakened alongside the currency, with the yield on the 2030 government bond adding 17.5 basis points to 9.075%. Thursday's rise was spurred by the South African Reserve Bank's decision to cuts its main lending rate for a fourth time this year to provide relief to households and firms battered by a nationwide lockdown linked to the coronavirus outbreak.

With friction between Washington and Beijing already mounting over the source of the coronavirus pandemic, China's proposal on Thursday to impose security laws on Hong Kong prompted a strong warning from US President Donald Trump.
