Saudi Arabia has sent a request for proposals (RFP) to banks for a planned U.S. dollar sukuk. The debt sale would be Saudi's second international bond offering, after the sovereign issued a debut $17.5 billion bond in October last year. Saudi Arabia is also expected to issue a conventional bond later this year. The kingdom's bond plans are part of its push towards a more diversified economy that is less reliant on oil exports. The RFP was issued at a busy time in the Gulf with other countries also planning to raise funds internationally to offset the impact of lower global oil prices. Bahrain launched a tap of its $1 billion 2028 bond on Tuesday, while Oman is expected to announce the launch of a new bond this week.
