Reforming the over-the-counter derivatives market: what’s to be gained?
While derivative financial instruments have made the hedging and exchange of risk more efficient, the recent crisis showed that they also pose a substantial threat to financial stability in times of systemic turmoil. Underlying much of this threat is the lack of transparent reporting in the over-the-counter market for these instruments. This Commentary discusses the advantages of one solution to the transparency proble: moving the settlement or trading of derivatives to exchanges or clearinghouses.Derivative securities ; Financial market regulatory reform ; Over-the-counter markets
Credit default swaps and their market function
Credit derivative instruments allow default risk to be segregated from debt of all kinds. They have granted investors the ability to hedge their portfolios and provided numerous institutions with a new source of income. However, the market for credit default swaps is neither transparent nor regulated, perhaps undermining the stability of the financial system it has helped innovate.Credit derivatives ; Swaps (Finance)
Effective practices in crisis resolution and the case of Sweden
The current financial crisis is a painful reminder that the developed world is not yet immune to these devastating shocks. But while we haven’t learned to prevent them, we have learned some lessons about what is necessary to contain them once they begin and to limit the damage that follows. As policymakers worldwide focus on resolving the current financial crisis, they might look to Sweden as a useful model for effective strategies.Financial crises - Sweden
Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases
The production of peroxide and superoxide is an inevitable consequence of
aerobic metabolism, and while these particular "reactive oxygen species" (ROSs)
can exhibit a number of biological effects, they are not of themselves
excessively reactive and thus they are not especially damaging at physiological
concentrations. However, their reactions with poorly liganded iron species can
lead to the catalytic production of the very reactive and dangerous hydroxyl
radical, which is exceptionally damaging, and a major cause of chronic
inflammation. We review the considerable and wide-ranging evidence for the
involvement of this combination of (su)peroxide and poorly liganded iron in a
large number of physiological and indeed pathological processes and
inflammatory disorders, especially those involving the progressive degradation
of cellular and organismal performance. These diseases share a great many
similarities and thus might be considered to have a common cause (i.e.
iron-catalysed free radical and especially hydroxyl radical generation). The
studies reviewed include those focused on a series of cardiovascular, metabolic
and neurological diseases, where iron can be found at the sites of plaques and
lesions, as well as studies showing the significance of iron to aging and
longevity. The effective chelation of iron by natural or synthetic ligands is
thus of major physiological (and potentially therapeutic) importance. As
systems properties, we need to recognise that physiological observables have
multiple molecular causes, and studying them in isolation leads to inconsistent
patterns of apparent causality when it is the simultaneous combination of
multiple factors that is responsible. This explains, for instance, the
decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference
