Central banks probably invest greater resources than any individual agent into studying the economy, assessing the economic situation and making forecasts. Reasonably, central banks should also know more about their own intentions than any other agent. It is therefore possible to construct theoretical cases where a lower degree of transparency is preferable to a higher degree. But on the whole the research appears to indicate quite clearly that a high degree of transparency is something the central banks should aim at. It is easy to agree with this conclusion. Here I think that the demands on a public authority in a democracy have great importance. Then I believe that in practice there are limits as to how transparent a central bank can be. In some respects it is quite simply difficult to be open and clear. This applies, for example, to how much emphasis the central bank places on stabilising the real economy relative to stabilising inflation. In theoretical models this is usually represented by a special parameter in the central bank’s so-called goal function. However, placing a value on this parameter which is then published would probably be  2  Morris, S. and H.S.

Since 2000, and especially in recent months, the picture has changed. The mines have opted for another strategy and have cut back on price hedging. This strategy change can be partly attributed to more positive expectations regarding the gold price. As a result of the central bank agreement on gold sales, producers no longer fear large-scale sales by the central banks. Moreover, it seems that producers have recently become more upbeat in their assessment of private investment demand. It is interesting, in this respect, that gold producers' hedging activity tends to accelerate market trends. When they expect price decreases, prices do in fact decrease faster as a result of hedging, and when they expect price rises, prices do rise faster owing to the decrease in hedging. Such strategy changes, which are always due to changed market expectations, have to be reckoned with in future as well. •  Reviving private investment demand in the industrialised countries has also contributed to giving the gold price a boost. This phenomenon has been particularly pronounced in Japan, but Europe and the United States have also seen gold demand booming. Economic imponderables, concern over the financial health of some companies, heightened political tension in different parts of the world, the terror attacks of September 2001 and concomitantly subdued stock markets have caused investors to increase their holdings of the  BIS Review 39/2002  1  yellow metal. It seems as if gold is, for the time being, once again assuming its role of a safe haven investment.
