Digital Currencies Issued by Central Banks:Central banks are developing digital currencies as a result of cryptocurrency market volatility and the rise of the digital yuan (e-CNY). They are treading carefully to develop their own prototypes to guard central bank independence and are cognizant that introduction of CBDCs may alter the financial markets in their jurisdictions. There is also a geopolitical component to CBDCs as they pertain to financial sovereignty.
U.S.-China Divide on CBDCs: The U.S. Federal Reserve (Fed) Board still debates digital dollar, while the Fed Banks of New York and Boston have developed CBDC prototypes. The White House is pursuing CBDC development. Meanwhile, China has launched e-CNY pilots in 26 cities, has partnered and competed with the Society for Worldwide Interbank Financial Telecommunication (SWIFT), and has joined the Bank for International Settlements (BIS) Innovation Hub-led CBDC interoperability tests.
Gulf States Vary in CBDC Development Stages: The Saudi Central Bank and the Central Bank of the United Arab Emirates (UAE) have conducted Project Aber, while Bahrain is in CBDC development stage. CBUAE has also participated in Project mBridge, in which interoperability was successfully tested with the central banks of China, Hong Kong, and Thailand. Meanwhile, Qatar and Oman are still in the research stage.
Korea and Singapore as Gulf CBDC Partners: The Bank of Korea (BOK) has piloted domestic tests with blockchain partners, while Samsung Electronics is developing the offline transaction CBDC prototypes. South Korea will be developing tokenized assets and wholesale CBDCs. The Monetary Authority of Singapore (MAS) has run interoperability tests with global partners for retail CBDCs. BOK and MAS will conduct Project Mandala at BIS, serving as potential partners for Gulf states in CBDC development and tests.
CBDCs are digital currencies issued by the central banks for which they are legally liable. CBDCs can be categorized into retail CBDCs for everyday transactions by individuals and businesses, and wholesale CBDCs for low-frequency, large-sum, or cross-border transactions by financial institutions. Currently, over 100 countries are advancing in CBDC development, whether in the research (46), or development (33), or pilot (21) phases. In addition, some jurisdictions (11) have already launched their CBDCs.1
Digital Currencies Issued by China’s Central Bank
Since the People’s Bank of China (PBOC), China’s central bank, began the development of the digital yuan (e-CNY) (which is not based on blockchain2 according to the PBOC) and showcased it during the 2022 Beijing Winter Olympics, concerns about surveillance and data privacy have been raised globally.3 These concerns persist, but opinions have shifted over time, especially with the Bank for International Settlements (BIS) releasing reports on CBDCs4 and launching Innovation Hubs around the world. The BIS has conducted interoperability tests through multiple CBDC projects with several like-minded central banks that are BIS members.
Digital Currencies Issued by the Central Bank of Saudi Arabia and UAE
In the Gulf, the Saudi Central Bank, previously known as the Saudi Arabian Monetary Authority (SAMA), and the Central Bank of the UAE (CBUAE) have conducted a CBDC interoperability test in 2019 under Project Aber (meaning ‘crossing borders’ in Arabic).5 In addition, the CBUAE participated in the interoperability test through Project mBridge at the BIS with the PBOC, Hong Kong Monetary Authority (HKMA), and the Bank of Thailand (BOT) in 2022.6 Bahrain is currently developing its CBDC prototype.7 In the broader Middle East and North Africa (MENA) region, the Bank of Israel completed two BIS-led interoperability tests: Project Icebreaker with the central banks of Sweden and Norway (which are outside the Eurozone) and Project Sela with HKMA, both completed in 2023.8
Variation in the Development of Digital Currencies Issued by Central Banks in the Gulf Countries
Among other Gulf Cooperation Council (GCC) states, Kuwait is progressing slowly, while Qatar and Oman have not advanced beyond the research stage.9 Why do disparities persist among Gulf states in CBDC development? Is the gap a result of varying levels of interest in CBDC development influenced by geopolitics, or does it stem from differing levels of technological capacity? If the gap is linked to technological capacity, could collaboration with technologically advanced countries from outside the region pave the way for CBDC blockchain development and interoperability tests? This issue brief investigates CBDC developments in the Gulf region as societies go cashless and other competing digital currencies (stablecoins and cryptocurrencies) expand their presence in the global financial market.
Given the different approaches by the United States (U.S.) and China on CBDCs, and the ongoing geopolitical tensions between them, Gulf countries are proceeding cautiously in the realm of CBDCs. This issue brief elucidates the contrasting positions on CBDCs in the U.S. and China, along with providing insights from South Korea and Singapore on their pilots and interoperability tests. Subsequently, the brief outlines CBDC development cases in the Gulf and Israel. It concludes with recommendations for Gulf states still in the research phase for CBDCs, proposing South Korea as a potential adviser and provider for CBDC blockchains based on its three previous pilot tests. Additionally, Singapore can be a partner for interoperability tests, given its involvement in multiple BIS projects.
In the U.S., conflicting interests and opinions regarding the launch of a digital dollar persist. The Fed’s Board of Governors itself has not arrived at a decision regarding CBDCs,10 and while the White House supports them,11 obtaining congressional approval and consensus can prove challenging due to diverse interests in the sophisticated U.S. financial market.
Meanwhile, there is a widespread perception in the United States that the U.S. dollar is firmly established as the global reserve currency, and although the digital yuan may pose a partial threat in the digital domain, it is not viewed as a significant challenge. Digital currencies, including cryptocurrencies and stablecoins, which are often pegged to the dollar or other assets, coexist and compete. Yet, regulating these digital currencies presents challenges, as there is no specific set of laws governing cryptocurrency. Consequently, the U.S. Securities and Exchange Commission (SEC) regulates the crypto industry on a case-by-case basis for violations of pertinent legislation, including the Securities Act of 1933 and the Securities Exchange Act of 1934.12
While China expands digital yuan pilots within its jurisdiction under the PBOC, the United States is closely monitoring digital yuan interoperability tests via the BIS (with the HKMA involved as the connecting node), in particular Project mBridge.13 This project, which includes the Bank of Thailand and the CBUAE, is gaining traction. In 2019, The Boston Fed discreetly conducted a pilot study for CBDCs under Project Hamilton in collaboration with the MIT Digital Currency Initiative.14 The New York Fed has been conducting a pilot for wholesale CBDCs under the inaugural Project Cedar with the installation of a BIS Innovation Hub (New York Innovation Center). The New York Fed has also collaborated with the Monetary Authority of Singapore (MAS) on connecting Project Cedar with Project Ubin.15
China is a front runner in CBDC development and has been expanding the digital yuan pilots across 26 cities16 in 17 provinces and the four municipalities of Beijing, Shanghai, Tianjin, and Chongqing.17 The cities that have been designated as pilot cities are southeast of the Hu Huanyong line.18 The partners for the PBOC’s digital yuan pilots include the seven major state-owned banks and other domestic commercial banks.19 The China branches of foreign banks also announced their joining of the pilot.20 Most recently, China has announced a QR code launch for digital yuan pilots in September 2023.21 China’s digital yuan transactions reached 1.8 trillion yuan (approximately $250 billion) by the end of June 2023,22 after hitting the 100 billion mark in August 2022.23 The PBOC also attempted its initial cross-border in digital yuan at the end of 2023.24 To use the digital yuan, consumers must download the digital RMB app25 and must consent to the usage of the digital wallet inside the app. Despite financial market participants’ and experts’ speculations that the use of the digital yuan aims to outplay WeChat pay and Alipay, the pilot tests co-exist with these digital payment apps.
Mu Changchun, the director of the Digital Currency Research Institute (DCRI) at the PBOC, emphasizes financial inclusion as a major goal of launching the digital yuan. This goal aligns with improving the efficiency of the central bank’s payment system and providing a backup for retail payment systems. However, speculations persist regarding China’s geopolitical motives for de-dollarization by offering an alternative transaction method to the dollar. To expand the digital yuan globally, the DCRI became part of a joint venture with the Society for Worldwide Interbank Financial Telecommunication (SWIFT), called Finance Gateway Information Services Co., partnering with China’s Cross-border Interbank Payment System (CIPS) and the Payment & Clearing Association of China – both supervised by the PBOC.26 This collaboration involves China partnering with SWIFT via CIPS while competing with the Belgium-based SWIFT—the foundation for U.S. financial sanctions. To evade U.S. sanctions, the transactions in CIPS must be in renminbi by CIPS members.27
South Korea’s Pilot Tests for the Digital Won Issuance.
In South Korea, the Bank of Korea (BOK) conducted three stages of CBDC pilot tests focusing on domestic pilots rather than interoperability tests with other jurisdictions. During the previous administration under Former President Moon Jae-in, heavy crypto trading prompted the South Korean government to regulate the crypto market by mandating all crypto exchanges to forego anonymity in individual wallets. Decentralized finance (DeFi) in this regard became difficult.28 The BOK conducted research for CBDCs from legal and technical perspectives, including two-stage mock pilot tests (August 2021 to October 2022)29 and two additional pilots within the BOK with stakeholders of financial institutions since December 2022. For the third stage, Samsung Electronics collaborated with BOK on offline CBDC technology using eSE (embedded Secure Element) chipsets through a memorandum of understanding (MOU).30
Issues pertaining to South Korea’s CBDC development and pilots included legal concerns31 about the BOK becoming the sole issuer of CBDCs,32 considerations for market volatility and competition, and technical difficulties regarding the transaction time when the CBDC prototype is built upon a blockchain. While the BOK has committed to CBDC development through pilot tests, it underlines through publications that there is no official intent to issue the digital South Korean won (KRW).
The BOK’s CBDC pilot evolved from six nodes (BOK and five virtual participant banks) based on a single cloud service to a connected pilot encompassing 12 Information technology (IT) centers with 18 nodes.33 The test revealed that the CBDC mock system in expanded form is functional.34 For improved operability of the expanded CBDC system, investigation into the transaction queue size and block construction would be required for continuous large-sum transactions to resolve the time lag in response wait times.35 Given that the South Korean fintech spectrum already provides numerous options for real-time transactions, the BOK sees limited benefit for retail CBDCs in South Korea, and is poised to construct an infrastructure for CBDC interoperability with BIS for large-sum transactions focusing on tokenized assets and wholesale CBDCs.36 The BOK will be participating in Project mBridge for interoperability tests and37 will be conducting wholesale CBDC interoperability tests for Project Mandala alongside the MAS, the Central Bank of Malaysia, and the Reserve Bank of Australia, as announced on October 4, 2023.38
Singapore’s Pilot Tests for the Digital Singapore Dollar Issuance.
On the other hand, Singapore has taken a comprehensive approach to CBDCs, conducting interoperability tests and engaging various stakeholders, including central banks and fintech companies. The MAS launched a BIS Innovation Hub in its jurisdiction, addressing the legal landscape for a digital Singaporean dollar (SGD). It has also conducted several interoperability projects with international financial institutions and various central banks via the BIS. Starting with domestic standalone Project Orchid for Singapore, which explored various designs for the digital Singapore dollar,39 the MAS has conducted Project Ubin and collaborated on Project Cedar Phase II with the New York Fed to test whether blockchains could enhance cross-border multi-currency transactions using wholesale CBDCs.40 Its Project Dunbar with the Reserve Bank of Australia, the Central Bank of Malaysia, and the South African Reserve Bank yielded results on enabling cheaper, faster, and safer cross-border payments.41 The MAS has also collaborated with the Swiss National Bank and the Bank of France on Project Mariana through the BIS, to test the cross-border trading and settlement using wholesale CBDCs.42 The MAS has been instrumental in bringing central banks together with different stakeholders in the financial and tech industries, ranging from the Bank of Korea, the Bank of Italy, the Development Bank of Singapore (DBS), the International Monetary Fund (IMF), Amazon, and J.P. Morgan, and proposing a “purpose-bound” CBDC, focused on issuing digital currencies without relying on a designated mediator.43 Overall, Singapore’s CBDC policy is geared towards flexibility, encompassing both wholesale and retail versions, blockchains, and various options including tokenized assets and stablecoins issued by the private sector.
In the Gulf region, SAMA and the CBUAE conducted their interoperability test through Project Aber in 2019. Project Aber, presumed to bring Gulf stakeholders to test multiple currency interoperability with the digital yuan, was not conducted in conjunction with BIS. Yet, Project Aber tested wholesale CBDC interoperability between Saudi and Emirati central banks, with three major retail commercial banks participating on each side. The Qatar Central Bank (QCB) remains in research mode44, while exploring the potential blockchain technology for Qatar’s CBDCs. It is estimated that QCB’s timeline to develop CBDC blockchains stretches to 2027.45
By comparison, the Bank of Israel has had two successful projects through the BIS for interoperability; most recently Project Sela with the HKMA46 and Project Icebreaker with Norges Bank (the central bank of Norway) and Sveriges Riksbank (the central bank of Sweden), in a partnership with the BIS Innovation Hub Nordic Centre.47 Given that HKMA is a participant in Project mBridge that connects with PBOC and that Norway and Sweden are outside the Eurozone but part of the European Economic Area, Israel’s role appears to be connecting the European region with the Asian region in terms of CBDC interoperability tests through the BIS.
Geopolitical and technological dimensions can explain the gaps between states in the region regarding their CBDC development. In the Gulf region, economic ties with China have become indispensable, but given the U.S.-China divide, countries are weary of the geopolitical climate regarding the issuance of CBDCs. Most Gulf states have their currencies pegged to the U.S. dollar, although they are exploring alternative settlement options in Chinese yuan via the Shanghai Petroleum and Natural Gas Exchange.48 One significant factor that has delayed CBDC development is the lack of technical expertise on digital blockchain technology or its application to a CBDC prototype, as well as uncertainty regarding how to select a trustworthy partner for collaboration. Given that blockchains are pursued for CBDC operability and interoperability tests are needed for cross-border transactions, identifying the right central banks and blockchain developers to work with on CBDCs will be an immediate task for Gulf states that are slow in CBDC development.
The surge of digital currencies, including cryptocurrencies and stablecoins, coupled with their volatility on the global financial market and China’s development of e-CNY, have prompted central banks worldwide to explore and develop their own CBDCs.
While various pilots, such as Project mBridge at the BIS and those in similar countries by central banks such as the MAS, along with standalone pilot tests by the BOK, indicate considerable interest in CBDCs, countries are approaching CBDC adoption cautiously. The key qualities for fintech cooperation on CBDCs for central banks are not only like-mindedness, but also matching the goals of CBDC development with trust and technological rigor to achieve interoperability. In this context, two Asian economies may be potential partners for Gulf states:
Seeking expertise from South Korea on blockchains and partnering with Singapore on CBDC interoperability tests via the BIS could prove beneficial for countries in the Gulf region.
