Egypt's main stock index, the EGX30 fell 1.46 percent to 8,211 points and the broader EGX70 slid 0.74 percent.
Comments made by Egypt’s presidential frontrunner Abdel-Fattah El-Sisi about his economic plan for the country may have contributed to the slump, according to Issa Fathy, vice president of the securities division at Cairo's Chamber of Commerce.
“Some of El-Sisi’s statements about controlling inflation frightened investors with the prospect of government intervention,” Fathy told Ahram Online.
In the second part of his first ever televised interview aired on Monday night, the popular former military leader spoke of installing "parallel mechanisms" to control prices if the private sector wasn't capable of doing it alone, and of urging the private sector to shrink its profit margin.
Egypt has seen inflation fluctuate sharply for the past three years. Most recently, annual inflation eased in April to 9.1 percent, but monthly inflation increased 0.6 percent in the same month.
