Well, to be fair, derivatives almost did blow up the world in 2008. Definitely overestimated in terms of impact, but really something we should have a better handle on.
- retube 11y agoExcept that derivatives were not the cause of the financial crisis. Over-enthusiastic mortgage lending to poor borrowers caused the financial crisis.
- RobertoG 11y agoOver-enthusiastic mortgage lending to poor borrowers without risk, because the risk was wisely managed and diversified through perfectly designed, financial, innovative products that covered all the bases (for a nice commission, of course).
- retube 11y agoYes but those products (Mortgage backed Securities) are cash products, like a bond or equity, NOT a derivative.
- RobertoG 11y agoDepends on the definition. The wikipedia editors think it is: https://en.wikipedia.org/wiki/Derivative_%28finance%29#Mortgage-backed_securities https://en.wikipedia.org/wiki/Derivative_%28finance%29#Mortg...
- skylan_q 11y agoThe mortgages everything was based on were junk, because they were guaranteed by the GSEs that couldn't handle the rate and size of the defaults on junk mortgages. Everything based on junk mortgages were junk.
- daveguy 11y agoThat is one part of it. Those mortgages could be blended into derivatives, which could then be run up in a speculative bubble. Pretending there was a single cause for the financial crisis is a little disingenuous on both our parts.
- retube 11y agowhat does "blended into derivatives" mean? Yes mortgages were sold on a packaged up into MBS (Mortgage back securities), but these are cash products, like a bond or equity, NOT a derivative.
- maxerickson 11y agoThere were MBSs built by splitting bundles of other MBSs into various tranches. Those certainly seem to be derivatives. What would they be called if they aren't derivatives?
- JumpCrisscross 11y agoPortfolios. There are synthetic MBSs, too. Those are derivatives. They were also relatively uncommon.
- retube 11y ago> What would they be called if they aren't derivatives? Securitised bonds, which is a cash product. The distinction between a cash & derivative product is really simple - one is leveraged the other isn't. E.g if I buy 100m of MBS I actually have to cough up 100m in cash - I am buying both the interest and principal repayments of the underlying mortgages. On the other hand if I enter into an interest rate swap with 100m notional I don't pay anything at all (assuming traded at spot market levels, and ignoring initial margin). The risk, or sensitivity, to interest rates is the same on both, but am only paying out cash for the securitised bond. Hence the bond, or MBS is "cash" and the swap is "derivative".

- jackcosgrove 11y agoDerivatives did exacerbate the unwinding of the mortgage mess, because the chain of title was so convoluted. I've read reports of people who were given homes in south Florida because the owners of mortgage debt were unable to finish foreclosure proceedings before the statute of limitations ran out. That is an extreme case, but the milder case of banks being landlords when that's not what they're good at, plus borrowers being stuck in foreclosure limbo longer than should be necessary, introduces unnecessary friction in the economy that wastes time and money. This could be the self-regulating limit for derivatives - the legal time required to unwind them in the case of mass redemptions, bounded by the business cycle length and statute of limitations for a locality.
- mullingitover 11y agoWeren't the banks selling each other credit default swaps they couldn't cover, such that the moment a single bank went under it triggered the collapse of the entire banking system? Blaming the mortgage lending is like saying, "I didn't blow up the neighborhood with my unsupervised warehouse full of explosives, it was those damn kids playing with matches!"
