Matzah prices in Israel have increased by up to 36% ahead of Passover, prompting the Economy Ministry to consider price regulation. Two leading matzah manufacturers, Matzot Yehuda and Matzot Rishon, are being investigated to assess the need for price controls. Despite rising costs, Passover matzah prices vary across major supermarket chains. The government has stated that it will take action if excessive profits are found, emphasizing the importance of affordable matzah for families during the holiday.
