Book Description
This paper explores whether a broader role for the SDR could contribute to the smooth functioning and stability of the international monetary system (IMS). Recent staff assessments highlighted that the IMS has displayed considerable resilience. But episodes of stress point also to some weaknesses, including in external adjustment mechanisms; limitations of official liquidity provisions through the Global Financial Safety Net (GFSN); and large-scale reserve accumulation—with systemic side effects. Those weaknesses, together with the expansion of the SDR basket, have renewed interest in the SDR and motivated a discussion of whether there is an economic rationale for a broader SDR role. The paper looks into how those weaknesses can be mitigated by three concepts of the SDR: the official SDR, the reserve asset administered by the IMF (O-SDR); SDR-denominated financial instruments, or “market SDRs” (M-SDR); and the SDR as a unit of account (U-SDR). However, the paper does not propose specific reform options.

Book Description
This book edited by Michael Mussa, James M. Boughton, and Peter Isard, records the proceedings of a seminar held at the IMF in March 1996 on the future of the special drawing right (SDR), given changes in the international monetary system since the inception of the SDR. The seminar focuses on the differences in opinion in the international community on the desirability or feasibility of an additional allocation of SDRs.

Book Description
Following the recent diagnostic of the international monetary system (IMS), the IMF will explore whether a broader role for the SDR could contribute to its smooth functioning. The economic rationale for or against broader use of the SDR will be examined, focusing in particular on identifying any gaps and market failures the SDR could help address in light of the increasingly multi-polar nature of the global economy and growing financial interconnectedness. This note sets out some initial considerations on this matter. The note sketches some key issues bearing on the role of the SDR in each of three concepts: (i) the official SDR, or “O-SDR”, the composite reserve asset issued and administered by the IMF; (ii) SDR-denominated financial market instruments, or “M-SDRs,” which could be both issued and held by any parties; and (iii) the SDR as a unit of account. M-SDRs reduce foreign exchange and interest rate risk relative to single-currency instruments, but there are some drawbacks and challenges. The basket nature of M-SDRs would allow the volatility of returns to be lower than for a similar singlecurrency instrument. However, the SDR only represents one of many possible sets of portfolio weights, and issuers or investors could use existing instruments to replicate their preferred weights at a relatively low cost. There are also challenges to market development, including settling and clearing of M-SDR transactions, dealing with potential basket redefinition, and fostering secondary market trading in order to generate liquidity and market depth. There are potential benefits to using the SDR as a unit of account, which have to be weighed against other considerations. Publishing economic statistics and financial statements in SDR terms could help users identify valuation changes. Statistical authorities would need to invest in communicating the rationale for any change in practices. While the official SDR under its current framework is not playing a significant role in the IMS, a re-examination of its role is expected to inform whether any specific reform options should be pursued. The evolution of the IMS has given rise to an active debate on how much concern is posed by high rates of reserve accumulation, global imbalances, and rising claims on reserve issuers, and on whether the O-SDR could contribute to addressing these issues.

Book Description
On March 5, 2021, the IMF’s Executive Board approved an extension of the current Special Drawing Right (SDR) valuation basket by ten months from September 30, 2021 to July 31, 2022. The IMF normally reviews the composition and valuation of the SDR basket every five years. The extension effectively resets the five-yearly cycle of SDR valuation reviews, with the next review to be completed by mid-2022 and the new basket becoming effective on August 1, 2022. The ten-month extension contributes to the Fund’s ongoing efforts to prioritize work during the COVID-19 crisis and allows for a more suitable effectiveness date of the new basket, which does not coincide with some major markets being closed. The approved extension, as well as effectiveness date of a new basket, is intended to facilitate the continued smooth functioning of SDR-related operations.

Book Description
Against the backdrop of the global financial crisis, the IMF has decided to implement a US$250 billion general allocation of special drawing rights (SDRs). In addition, the Fourth Amendment of the Fund’s Articles of Agreement has recently become effective, and will make available to SDR Department participants a special allocation of up to an additional SDR 21.5 billion (US$33 billion). Nearly US$115 billion of these combined allocations will go to emerging market and developing countries, including about US$20 billion to low-income countries (LICs), thereby providing an important boost to the reserves of countries with the greatest needs.

Book Description
This paper provides the basis for the quinquennial review by the Executive Board of the method of valuation of the Special Drawing Right (SDR). The review covers the composition and weighting of the SDR currency basket, and the financial instruments used to determine the SDR interest rate. In the five-year period for this review (2017‒21), developments in key variables relevant for the SDR valuation suggest that there have been no major changes in the roles of currencies in the world economy. The countries and the currency union (euro area) whose currencies are currently included in the SDR basket remain the five largest exporters and their currencies continue to account for the majority of international financial transactions. Moreover, staff analysis finds that the COVID-19 pandemic and recent fintech developments have no systematic or material impact on the SDR valuation. The paper proposes to maintain the current composition of the SDR currency and interest rate baskets, as well as the method for determining the currency weights and currency amounts in the basket. In line with the Board-approved methodology, the paper proposes updated weights for the currencies in the SDR basket. These maintain the same ranking of the initial weights set in the 2015 review, with slightly higher weights for the U.S. dollar and the Chinese renminbi and, accordingly, somewhat lower weights for the British pound, the euro, and the Japanese yen. The paper also proposes to make explicit the treatment of data gaps in the SDR valuation framework. Findings from a survey of SDR department participants and prescribed holders are used to follow up on operational issues raised in earlier valuation reviews. The new SDR valuation and interest rate baskets are proposed to come into effect on August 1, 2022 for a period of five years.

Book Description
This paper proposes an extension of the current SDR valuation basket for a period of nine months to September 30, 2016. This extension would respond to feedback from SDR users on the desirability of avoiding changes in the basket at the end of the calendar year and facilitate the continued smooth functioning of SDR-related operations. As discussed at the informal Board meeting on July 29, this proposal does not in any way prejudge the outcome of the Review of the Method of Valuation of the SDR.
