But data from different decentralised sources are not structured, there is a lack of transparency in methodology, no representativeness, and no use of international standards, concepts and semantics. Hence, there is a need to streamline the wealth of information to structured, understandable, shareable and most of all, reliable data of the future. The latter is prerequisite to preclude devaluation of the data, and statistics plays a critical role in preserving the value of data. In the new era when we have open access to multiple sources of information, it is not enough official statistics to be disseminated more effectively, but it has to be accepted, understood and trusted by the general public. Good official statistics, as dramatically shown during the Covid-19 crisis, can be crucial to provide a first line of defence against misinformation (Biancotti et al., 2020)2. High quality and reliable statistics is the "weapon" against fake news and divisive messages. More than ever as policy makers we are faced with misinformation, fake news and speculations that can undermine our ability to act effectively. The digital environment, the growing role of social media and absence of clear regulatory framework propelled the dissemination of the so called "mal-information". For example, we as a central bank, faced ungrounded speculations against the exchange rate on a couple of occasions. Keeping us 24/7 alerted is the least damage that this type of irresponsible behaviour implies.
4  BIS Review 145/2010  As I mentioned earlier, the Fund has become larger than we expected a decade or so ago as high oil prices have more than compensated for fairly low returns in international capital markets. Looking ahead, market prices suggest that interest rates are expected to remain low for many years. Real interest rates on long-term bonds have been depressed by central bank government bond purchases. Let us nonetheless assume an average nominal return on the Fund’s fixed income instruments of 3 per cent ahead. On the other hand, there are no signs that return requirements in equity markets are low. Dividend payments are high in relation to companies’ market value. Simple valuation models 9 indicate that shareholders require a rate of return between 8 and 10 per cent, a fairly normal level. This results in an overall nominal return of between 6 and 7 per cent. In addition, positive contributions to the return are expected from non-government bonds, active management and real estate. There is considerable uncertainty surrounding these estimates. Nevertheless, Norges Bank’s view is that it is still reasonable for the government to base its withdrawals from the Fund on an expected annual real rate of return of 4 per cent. The increase in the equity allocation from 40 per cent to 60 per cent does not provide a basis for higher withdrawals from the Fund, but reflects prospects for somewhat weaker returns in international markets today than was the case ten years ago.
