The International Monetary Fund delivered a valuable imprimatur of respectability to Beijing last week, when it declared that its exchange rate was probably no longer undervalued. The assessment was not a surprise: respected independent outfits such as the Peterson Institute and the consultancy Oxford Economics have been saying similar for a while.
国际货币基金组织(IMF)近日宣布人民币汇率很可能不再被低估，这相当于对北京的声誉予以了宝贵的认可。这样的评估结果不算出人意料：包括彼得森国际经济研究所(Peterson Institute)与咨询机构牛津经济研究院(Oxford Economics)在内，许多受尊敬的独立机构一段时间以来就一再表达了类似的看法。
The judgment increases the already rising probability that the renminbi might be included in the units that make up Special Drawing Rights (SDR), commonly though inaccurately known as the IMF’s currency, when the composition of the basket is reassessed later this year. Some regard this as a pivotal moment in the internationalisation of the renminbi. But history suggests that, while it may be symbolically important, membership of the SDR is neither necessary nor sufficient for the renminbi’s acceptance as a global reserve currency.
IMF的结论提高了一种本来就在不断上升的可能性：今年晚些时候IMF重新评估特别提款权(SDR)货币篮子的构成时，有可能决定将人民币纳入这个篮子。所谓SDR，也就是人们常说的IMF货币，虽然这种叫法并不准确。有些人认为，这将是人民币国际化进程中的一个关键时刻。但历史经验表明，虽然加入SDR或许具有重要的象征意义，但对于人民币成为一种公认的全球储备货币来说，这既非必要条件，也非充分条件。

The SDR asset, sometimes likened to a monetary Esperanto, is a peculiar creature. Created in the 1960s to meet the world’s demand for reserve assets when the dollar — constrained by its link to gold — could not do so, that rationale disappeared when the Bretton Woods system collapsed in the early 1970s. Since then, even after the creation of $250bn in SDRs in 2009 to boost reserves and liquidity during the global financial crisis, they make up less than 4 per cent of non-gold global official foreign exchange reserves, less than half the level in the 1970s.
SDR资产是一种奇特的产物，有时被比喻为货币领域的世界语。它诞生于上世纪60年代，目的是满足世界对储备资产的需求，因为当时美元受制于与黄金挂钩无法担当此任。然而，当布雷顿森林体系(Bretton Woods)于上世纪70年代初瓦解后，这种理由也就不存在了。从那时起，包括在2009年新增2500亿美元SDR以提振全球金融危机期间的储备和流动性之后，其在全球官方非黄金外汇储备中所占的比例都不到4%，还不到上世纪70年代水平的一半。
This renders the SDR largely irrelevant except in a minor role as an accounting unit: the basket of four currencies that compose it — the dollar, the euro, the yen and sterling — is occasionally used to value internationally traded goods. There is no liquid private market in SDR assets and to use SDRs for intervention or other purposes first requires them being broken down into their constituent currencies.
这使得SDR大体上变得无足轻重，除了作为一种核算单位的次要角色：由4种货币（美元、欧元、日元和英镑）构成的货币篮子只是偶尔被用于评估国际贸易商品的价值。目前不存在具有流动性的SDR资产私人市场，而要利用SDR资产进行干预或其他目的，首先需要把它们分解为成分货币。
A few years ago Zhou Xiaochuan, then governor of the People’s Bank of China, called for the SDR to become a super-sovereign reserve currency. That call was treated respectfully as a contribution to the global monetary governance debate in much of the world. In the US, probably correctly, it was regarded as part of China’s campaign to get other countries to bail it out of its own lopsided reserve accumulation policies by allowing Beijing to transform its dollar-denominated reserves into SDRs without selling its dollars on the open market.
中国人民银行行长周小川几年前曾呼吁将SDR变成一种超主权储备货币。他的呼吁在世界大部分地区被尊称为对全球货币管理辩论的贡献。在美国，周的呼吁被认为是中国策略的一部分，目的是让其他国家帮助自己摆脱不平衡的外汇储备积累政策，方便北京将美元计值的储备资产转变为SDR资产，而无需在公开市场出售美元——这种观点或许是正确的。
The renminbi’s potential addition to the SDR, whose basket is reviewed every five years, carries risks for the credibility of the asset itself. If the unit is to take off as a reserve and indeed privately held asset, it will need to develop a deep and liquid market. This may not be assisted by the addition of a currency like the renminbi which, though its use has been growing rapidly, is still not much traded in foreign exchanges and which has a very small share of global bond markets and cross-border bank lending.
人民币加入SDR（其货币篮子每五年审核一次）会给SDR资产自身的信誉带来风险。如果SDR要成为一种储备资产甚至是私人持有的资产，它需要发展成一个具备深度和流动性的市场。而人民币的加入可能并不会助推这一进程，虽然人民币的使用量一直在迅速增长，但它在外汇市场中的交易量仍然不多，而且在全球债券市场和跨境银行放贷中所占份额也很小。
It is not at all clear that the renminbi meets the IMF’s requirement to be “freely usable”. The renminbi is neither fully convertible nor free-floating, remaining subject to capital controls and opportunistic open market intervention. The inclusion of illiquid currencies has weakened the SDR in the past. To make it tractable at all, the IMF membership had to whittle the basket down from its original sixteen currencies in the 1970s to five after 1981, later compressed to four as the D-Mark and the French franc were subsumed into the euro.
目前完全不清楚的是，人民币是否满足IMF关于“可自由使用”的条件。人民币既不是完全可兑换，也不能自由浮动，仍受制于资本管制以及相机而动的公开市场干预。历史上，IMF将低流动性货币纳入SDR曾削弱了SDR。为了更加便于管控，IMF不得不将货币篮子从上世纪70年代的16种货币削减至1981年后的5种，后来随着德国马克和法国法郎被并入欧元又减少至4种。
As for the renminbi itself, it would undoubtedly get a symbolic boost to its credibility by being invited into the SDR basket with the big kids. But reserves managers around the world are conservative and independent characters, and are unlikely to outsource their assessment of what constitutes a liquid and reliable currency to a politically influenced process at the IMF. They are much more likely to want to hold renminbi assets if they know they can be bought and sold easily and quickly and that the value of the currency is not going to be jerked around by political meddling.
至于人民币本身，被邀加入SDR货币篮子（从而跻身主流货币行列）对其信誉无疑会起到象征性的提升作用。但世界各地的外汇储备管理者都是保守、独立的人士，他们不大可能会将自己评估一种货币是否具有流动性和可信度的任务外包给IMF的一项受政治影响的程序。如果他们知道人民币资产能够便利、快速地买卖，而且其价值不受政治干预所左右，他们会更有可能想要持有人民币资产。
Precautionary reserves are held for the purposes of market intervention, not to earn a return, so deep and liquid markets are leading concerns. SDR membership is neither necessary nor sufficient for reserve asset status. The Swiss franc, for example, is quite widely held as a reserve currency (certainly relative to the size of the Swiss economy) without being in the SDR basket.
持有预防性储备的目的是为了进行市场干预，而不是为了获得回报，所以有深度、有流动性的市场是首要的考量。SDR资格对于储备资产地位来说既不是必要条件，也不是充分条件。例如，瑞士法郎并没有被纳入SDR货币篮子，但它被相当普遍地（当然是相对于瑞士经济规模而言）作为一种储备货币而持有。
Researchers at Citi asked official reserves managers recently if they agreed that SDR membership would increase their willingness to hold renminbi assets (Citi economists themselves are bullish on the issue). On average they found the answer somewhere between “agree” and “neither agree nor disagree”: not nothing, but unlikely to be a major influence.
花旗(Citi)的研究人员最近询问了官方储备管理者，他们是否同意，人民币加入SDR将增加他们持有人民币资产的意愿（花旗的经济学家们对此持乐观态度）。总的看来，他们发现答案介于“同意”和“既不同意也不反对”之间：不是没有影响，但不大可能造成重要影响。
As it happens, perhaps unexpectedly, the euro may serve as an example of reserves management reality overcoming symbolism. Upon its launch in 1999, the euro was often predicted to rival the dollar as a global reserve asset, eliminating the exchange rate risk between different European currencies and forming the basis of a large and unified pool of assets.
欧元或许可以作为外汇储备管理方面现实战胜象征意义的一个例子，这一点人们可能不曾料到。1999年欧元问世时，人们通常预计欧元将会与美元竞争全球储备货币的地位，它将消除欧洲不同国家货币间的汇率风险，并作为一个庞大而统一的资产池的基础。
In practice, the euro’s share of reported global reserves, after rising to around a quarter, stalled and then somewhat fell back. The inept management of the euro crisis may be a factor, as may the fact that the eurozone sovereign bond market remains fractured into liquid safe assets (Bunds) and riskier instruments (most of the rest). But even before the crisis, the habit of European politicians in trying to talk down the euro whenever they considered it to be threatening their exports caused amused head-shaking by their American counterparts, who regarded the hands-off “strong dollar” policy as integral to the greenback’s status as a reserve currency. (Of course, it remains to be seen what effect on confidence will have the campaigns of quantitative easing in all four SDR currency areas, with consequent large swings in exchange rates, albeit without forex intervention.) China is likely to keep the nominal renminbi-dollar rate stable between now and the decision on the SDR at the end of the year, but is unlikely to eschew various forms of meddling indefinitely.
在现实中，欧元在全球外汇储备公开数据中所占的份额先是上升至25%左右，然后停滞不前，后来又有所回落。对欧元区危机处理不当可能是一个因素，而以下事实可能也有影响：欧元区主权债券市场仍分裂为流动、安全的资产（德国国债）和风险较高的工具（其余大部分）。但在危机爆发前，欧洲政界人士每次感觉出口受到威胁时就试图口头压低欧元的习惯，屡屡让美国同行笑着摇头，后者将放任自流的“强势美元”政策视为美元储备货币地位的一个要素。（当然，所有4种SDR货币区域都采取的量化宽松以及尽管没有外汇干预却伴随而来的汇率大幅波动，会对市场信心产生怎样的影响还有待观察）。从现在开始到年底IMF做出关于SDR的决定前，中国很可能会保持名义人民币兑美元汇率的稳定，但不大可能无限期地回避使用各种形式的干预措施。
China has been moving, sometimes slowly and jerkily, towards turning the renminbi into a floating convertible currency and a reserve asset. The prospect of SDR membership may encourage that process, or at least help to lock in what progress has been made so far. But it seems unlikely, by and of itself, to make a material difference to whether renminbi-denominated assets become a major part of the world’s foreign exchange reserves in the medium term.
中国一直在朝着将人民币转变成一种自由浮动可兑换货币以及一种储备货币的方向前进，虽然有时行动缓慢，脚步不稳。加入SDR的前景可能会鼓舞这一进程，或者至少有助于巩固迄今取得的进展。但中期内要使人民币资产成为世界外汇储备中的重要组成部分，单凭加入SDR这一点似乎不大可能起到什么实质作用。
