0.  前言

這篇不到800字的短文說得上短小精悍(請見本欄下一 )人民幣能否取代美元?」是一個熱門話題;為了讓我自己有所了解,也方便網友們閱讀,第一節中我先簡單譯述該文重點;請參考本欄轉載原文所附各段序號。我不揣簡陋,略誌數語於第二節;各位可以自行判斷作者結論是否說得通

另請參見此欄此欄從根兒上理解美元【湯山老王】(視頻)

1.

評論

首先聲明:我不是財經、金融、或外匯專家,以下淺見純屬獻曝。

1)  
我雖然不是專家,已如上述;但以見過豬走路的常識來看,原文第6 – 8段所說,應該稱得上「言之成理」。
2)  
如果接受這個判斷,則原文第9 – 10段所說,也就「言而有據」了。
3)  
原文第11段的結論,在我看來,則不免「武斷」之譏;理由如下:
3a) 
我在第1-4)小段用了原文所無的必要條件」一詞。實務上,一個條件」是否必要」;以及某人、某事、某物等是否具有」該條件」兩者;和客觀環境相關。換句話說,如果美國淪為二流國家如英、法、德等,則美元現有的「流通性」和市場深廣度」可能隨之泡湯。反之,如果中國在經濟規模和整體國力上大幅超越美國,則人民幣的「流通性」和市場深廣度」可能跟著一飛沖天。
3b) 
同理,任何政策」或治理」理念/方式都是客觀環境的函數。目前中國政府對外匯」和金融機構」的管控,應該不是因為:具有控制狂」特質的人才能爬到中央政治局常委的地位;而是因為:在國內、外政治環境的制約下,不得不採取這些措施。或者說,中國領導階層認為:(至少在他們認知裏)這些措施是應付中國目前客觀環境最適當的策略。
4)  
我同意:三、五年內,甚至10 -- 20年內,人民幣都難以取代美元在國際貿易和外匯市場上的地位。一來百足之蟲死而不僵」和瘦死的駱駝比馬大」;二來,雖然中國超越美國這個結果毋庸置疑,但因為各種變數太多,時程上還真不好說。
5).  
最後,我認為:不論以社會主義或資本主義掛帥,市場」和控管」這兩個概念具有內在矛盾」。同樣的,做夢」和控管」這兩個行為也具有執行面矛盾」。我不是說:領導者必須在兩者間做一個取此捨彼」的決定;而是說:兩者間需要取得一個黃金平衡點」。否則,落個兩頭空不是意外之事。萬一搞到全民揭竿而起才春夢乍醒,那就會遺臭或貽笑萬年了。

Why China’s Yuan Can’t Replace the U.S. Dollar

Milton Ezrati, 05/21/25

1.  Now that Washington and Beijing have reached a 
compromise on trade, currency concerns have re-emerged. The worry (or hope, depending on the publication or podcast) is that China’s yuan will supplant the dollar as the premier global currency. Beijing certainly likes the idea of the yuan becoming the preferred means of exchange for bankers and currency traders.

2.  For years, Chinese policy has strived to raise the yuan’s international stature. However, the yuan still has a long way to go to supplant the dollar, and it is far from apparent that the 
Chinese Communist Party’s (CCP) obsession with control will ever allow the changes needed for that to happen.

3.  Of course, there is no denying that the 
U.S. economy and the dollar have long since lost the overwhelming dominance they once held. That is clearly a consideration that every nation on earth has taken into account. But in this matter, comparative differences matter more than absolute dominance. The dollar, for all the decline fall from its former strength, remains the only currency that has all the characteristics needed to serve as a global reserve. That is especially true when compared to China’s yuan.

4.  Beijing has done much to raise the yuan’s international stature, actions that have rightly captured media attention. Indeed, Beijing has strived to create what some have called a “
Sino-centric system.” China demands yuan-based trade and capital flows in large parts of its far-flung Belt and Road Initiative (BRI). It has created an Asian Infrastructure Investment Bank that deals with yuan-based loans and transfers. Beijing successfully pressed the International Monetary Fund (IMF) to include the yuan among currencies it offers through “special drawing rights.” The People’s Bank of China (PBOC) has added to this effort by promoting a digital yuan.

5.  But all this effort has barely moved the needle against the
 dollar’s use in international transactions. Some 80 percent of global trade is conducted in dollars, even when Americans are not involved. The dollar lies on one side or the other in some 90 percent of all currency transactions. In contrast, the yuan is present in a mere 4 percent of such transactions, and even the euro can claim only a 30 percent share. The conversion of Egyptian pounds into yuan, for instance, typically occurs via the dollar. So, too, most other currencies. 

6.  These well-entrenched relationships have taken years to develop, and it would take years to unwind in the yuan’s favor. Moreover, the yuan has two other disadvantages in its quest to supplant the dollar. China’s financial markets have neither liquidity nor what financial people call market depth, which is needed for the role of global reserve. 

7.  Liquidity is essential. Importers, exporters, and their financial support demand the global currency to be able to trade seven days a week, twenty-four hours a day. Their business demands that kind of convenience and flexibility. The dollar offers it. The yuan does not. Then, there is the size of dollar-based financial markets. The overwhelming amount of dollar assets outstanding and the huge trading flows that go on all the time mean that people can move huge sums with minimal effect on the prices of either currencies or financial assets. Dollar-based markets offer this. Yuan-based markets do not.

8.  Because global trade and finance demands that people hold deposits and assets in the reserve currency, they also seek a variety of financial instruments to choose from, some short-term, for example, some long-term, and some offering derivatives that allow hedges against volatility. Again, dollar-based markets offer such a variety in abundance; Yuan-based markets are unable to compete.

9.  Though yuan-based markets could develop such levels of liquidity and depth over time, there is still another major impediment. In order to accomplish this, China’s authorities—the CCP— would have to abandon their obsession with control. The People’s Bank of China (PBOC) would have to end its present insistence on keeping the yuan’s foreign exchange value within a tight range and allow it to float freely on global markets. 

10. To offer people the ability to buy and sell assets and currencies easily with a minimum of price disruption, Beijing would need to give up its present insistence on 
controlling capital and investment flows into and out of the country as well as its insistence on restricting what financial institutions can do business in China. 

11. Such necessary change is not just contrary to current Chinese practice. It is antithetical to the CCP’s approach to governance. If not impossible, such changes certainly are not likely. The dollar’s premier status will certainly face challenges in time, but the yuan does not threaten as yet and does not look as if it ever will.
