Point-of-sale transactions routed through Pakistan’s main digital payments system fell by nearly 50% the day after former Prime Minister Imran Khan’s arrest ignited countrywide protests and prompted authorities to shut down mobile internet services, data showed on Thursday.

The reason for the slump was primarily the mobile broadband suspension, in addition to lower footfall at the limited number of stores opened due to the political turmoil, payments system operator 1LINK told Reuters.

The violent protests that followed Khan’s arrest on Tuesday by the country’s anti-graft agency have hit commercial activity in Pakistan hard.

Mobile data services have remained shut since Tuesday night on the orders of the interior ministry – the longest such continuous shutdown in a country that often suspends communications as a tool to quell unrest.

Many major roads and businesses have also remained shut, mainly in the eastern city of Lahore, Pakistan’s second-largest city.

Data shared with Reuters by 1LINK on point-of-sale (POS) through its platform showed international payment card transactions were down on Wednesday by 45% in volume, from a daily average of 127,000 during the week of May 1 to 7 to approximately 68,000 on May 10.

The daily value of transactions using international payment cards was down 46%, from 606 million rupees ($2.14 million) to 330 million rupees ($1.16 million) on May 10.

1LINK is Pakistan’s major facilitator of POS digital payment transactions for international platforms such as Visa and Mastercard.

Transactions on Pakistan’s only domestic payment scheme, PayPak, were down 52% in volume to 18,000 transactions on Wednesday, and 56% down in value to roughly 62 million rupees ($218,775).

The State Bank of Pakistan did not immediately respond to questions sent by Reuters.
