金融世界 第十五讲
上一讲中我们为您介绍了 floating exchange rates 和 fixed exchange rates，浮动汇率与固定汇率。澳广金融节目主持人巴里克拉克介绍说，二十世纪的固定汇率制不仅未能保持汇率的稳定，而且还为投机者提供了机会。
但是实行浮动汇率制也同样有它的不利之处。不断变化的汇率为工商业的运作带来许多不确定因素。
不过，澳洲广播电台金融节目主持人巴里克拉克继续介绍说，各国的中央银行或储备银行大都会在关键时刻对市场进行干预，以减缓货币汇率的剧烈动荡。
巴里克拉克在他的讲话中提到了这样一些词汇：
1 Reserve Bank 储备银行
2 cushion 缓冲垫，减震器
3 intervene 干预
4 contention 辩论
5 on balance 总的来说
6overshooting 过火，过激
下面我们听一遍巴里克拉克的谈话及中文翻译：
The Reserve Bank tries to play a role in providing a comfort cushion by intervening from time to time in the foreign exchange market with a view to limiting its more extreme fluctuations.
Whether the central bank should be doing this, and whether it actually can influence exchange rates in the face of market forces, are matters of some contention.
From its own analysis, the Reserve Bank is persuaded that, on balance, it plays a useful role in limiting overshooting in the market.
巴里克拉克说，储备银行试图在减缓市场冲击力方面发挥作用，对外汇市场不时进行干预，目的是要限制它更剧烈的动荡。
中央银行是否应当采取这样的行动，以及它在面对市场力量时是否真能对汇率发挥影响，是需要继续讨论的问题。
储备银行通过它自己的分析，确信它总的来说在限制市场的过激行为方面能够发挥有益的作用。
下面我们再听一遍巴里克拉克的这段谈话。（略）
刚才我们谈到了中央银行对外汇兑换市场的干预。许多经济学家对中央银行进行干预的效果持怀疑态度。美国斯坦福大学经济学教授安妮克鲁格就是其中之一。她说：
The first question is: can a central bank out-guess the market in terms of where the underlying market forces are taking the exchange rate? More interventiongs than not, I think, historically, have been when the central bank has been betting against the market. You may recall in 1992 when you had the upheavals in the European currencies, where there were a lot of bets against the markets and a lot of money was lost on the part of a lot of countries, including the Bank of England. So that basically, there's a real risk in central bank intervention.
安妮克鲁格教授说，首先的问题是，中央银行是否能够猜中潜在的市场势力会把市场汇率带向何处。我认为从历史上来看，多数市场的干预都是中央银行逆市场走向下的赌注。可以回想一下1992年欧洲货币的那场大动荡。当时许多人都逆市场而动，投下大批赌注，很多国家都损失了大笔的资金，包括英格兰银行在内。因此基本上来说，中央银行的干预确实存在着危险。
I think central bank intervention is dangerous. They're betting on one side of the market and then that gives speculators a one-sided bet, because they know that they can't really lose by going on the other side.
我认为中央银行的干预是危险的。它们就市场的一方打赌，这就给了投机者向另一方下赌注的机会。因为投机者知道投向另一方就肯定不会输。
