Healthy markets require solid data based on reality.
It is hard enough to determine what, when and how to invest even with solid data. We live in an unpredictable and chaotic world, and the last thing that investors need is misinformation and distortions. That is why the LIBOR manipulation scandal is so infuriating; as banks skewed the figures, they skewed entire marketplaces. The level of economic distortion is incalculable — as LIBOR is used to price hundreds of trillions of assets, the effects cascaded across the entire financial system and the wider world. An unquantifiable number of good trades were made bad, and vice verse. Yet in truth we should not expect anything else from a self-reported system like LIBOR. Without real checks and balances to make sure that the data is sturdy, data should be treated as completely unreliable.
Unsurprisingly, it is emerging that many more self-reported figures may have been skewed by self-reporting bullshittery.
The Telegraph noted:
The Libor scandal could be repeated in a number of other “self-certifying” markets where prices are determined, he said.
