Maybe that’s a disturbing mental image, but the title is more than apt given Gensler’s recent NYT oped, “Libor, Naked and Exposed.” As is his wont, demonstrated repeatedly on Frankendodd-related issues such as clearing and SEF mandates, Gensler presents a misleading and distorted analysis to advance some regulatory or political agenda.
Gensler questions the integrity of Libor. This is certainly understandable in the light of the deluge of revelations in the past couple of months. But the “evidence” that Gensler uses to justify his skepticism is completely off point, and certainly grossly overstates the impact of any manipulation on this important benchmark rate.
The first comparison Gensler makes is between Libor and Euribor. He notes that dollar Euribor is about double dollar Libor. But what Gensler omits to say is that this is an apples to horse apples comparison, given the major differences between the banks in the Libor and Euribor panels. The former includes major banks (crucially, TBTF banks that benefit from the implicit and explicit support of governments and central banks), and most notably major US banks with ready access to dollar funding. The latter includes something of a dog’s breakfast of foreign banks. It has two Spanish and one Portuguese cajas and five German landesbanken, for crissakes. And Dexia! The Euribor panel banks are all weaker, and don’t benefit from the same safety net as the banks in the Libor panel. Moreover, since the beginning of the crisis, foreign banks have much greater difficulty in securing dollar funding than US banks. Even big European banks (such as French giants like Paribas) have faced acute dollar funding problems. This is one reason why they have been deleveraging, and selling off dollar assets. The Euribor banks almost certainly have even worse problems.
This issue of fragmentation of funding markets also bears on Gensler’s second piece of evidence: the divergence between Libor and the dollar rate implicit in FX swap prices. Gensler treats the violation of the interest rate parity relation as an indicia of manipulation.
But again, this reflects the acute problems European banks have faced in securing dollar funding. They can borrow in Euros, but have to swap it into dollars to fund their dollar assets. They are willing to, and the market is making them, pay a premium to execute this transaction.
Gensler claims “this divergence between theory and practice has yet to be adequately explained.” Really? It is well-understood. Don’t believe me? How about some economists from the New York Fed? They investigated this issue in detail in 2009, and concluded that the divergence in the basis between the FX swap implied USD rate and USD Libor was caused by the dislocations associated with the financial crisis.
Indeed, Gensler’s oped implicitly recognizes this: he notes that implied and Libor rates have not been aligned “since 2008.” Hmm. What happened in 2008? Think, think, think. A financial crisis maybe? Could that be it? I’m thinkin’.
One key piece of evidence that FRBNY economists Coffey, Hrung, Nguyen, and Sakar present is that the basis blowout was not limited to Libor. It was also present when they used the New York Funding Rate produced by ICAP. It was also present when they used Eurodollar deposit rates.
Look, anybody who has followed this knows that basis relationships that had been steady as a rock for years went haywire starting in August, 2007. (Happy Anniversary!) The CDS-cash bond basis went haywire. Interest rate spreads (e.g., OIS-Libor) went haywire. Spreads between borrowing rates across banks have become much more dispersed and become much more volatile. (This relates directly to the Euribor-Libor comparison: banks are much more heterogeneous now than in, say, 2006, making comparisons between averages across different groups of banks much less meaningful now than then.)
This pertains to another piece of evidence: the lack of comovement between bank CDS spreads and their Libor submissions. This could be informative, particularly in normal times, but it is problematic during crisis times. CDS spreads and yields on the underlying cash bonds diverged dramatically, and often exhibited little comovement, during the period of the crisis. CDS spreads were being driven by liquidity and risk aversion issues. If the CDS-cash bond basis became much more volatile, it’s not at all surprising that the CDS-Libor spread also became much more variable, given that CDS and cash bonds have closer kinship than CDS and unsecured short term borrowings.
Noticing a pattern here? Basis relationships of every sort became much more volatile during the crisis period, and hence are far less reliable evidence of manipulation in Libor than would have been the case more than 5 years ago. In essence, Gensler is trying to tell time with a broken watch.
Recall that Gensler mentions “the divergence between theory and practice.” Anybody who has been paying attention understands why that’s true. The theory is predicated on an assumption of frictionless financial markets. Financial markets where capital and liquidity constraints are not binding, thereby permitting arbitrageurs to eliminate swiftly divergences in prices across related markets. That was a reasonable approximation of reality in say, July, 2007: certainly in July, 2005. It is completely unreasonable post-August, 2007.
Or as the FRBNY economists put it:
The widening of the basis illustrates the breakdown in arbitrage relationships that has afflicted many markets during the financial crisis. For example, eurodollar interest rates in New York and London diverged during the crisis-as did yields on corporate bonds and credit default swaps, which are closely related securities. The element common to all of these phenomena was increased funding costs, which impeded arbitrageurs from shrinking the basis between these types of securities. In addition, counterparty credit risk became prominent, and previously risk-free arbitrage trades suddenly became risky . . . funding constraints and counterparty risk explain the rise in the basis and the relative importance of each factor changed as the crisis evolved. [Emphasis added].
Since then, the coefficient of financial friction has reached record levels. Capital and liquidity and funding constraints are binding everywhere, and binding hard. In particular funding markets-and Libor is a measure of a funding costs for some banks-have been dysfunctional for 5 years. Severely dysfunctional. Most of the European banking system relies on the ECB for funding. Markets across regions that were once highly integrated are now fragmented as never before.
This is particularly important for dollars. Having access to dollar funding via deposits and access to the Fed (like major US banks) is completely different than having to raise dollars through wholesale markets, like most European banks that have been hit hard by the flight of US money market funds and other sources of dollar liquidity. This is what drives things like the Euribor-Libor differential, and the swap-Libor basis.
Hell, there is fragmentation of funding even within currency areas, in particular, the Eurozone. European subsidiaries are attempting to fund their local lending with local deposits, especially in countries where conversion risk (i.e., the risk that a country will leave the Euro) is acute. For instance, Italian subsidiaries of French banks are funding their loans to Italian businesses with local deposits, rather than money from the parent banks.
In other words, Gensler is relying on a textbook model that presumes a frictionless world. That ain’t our world, today. The textbook needs to be thrown out. But Gensler uses it as his bible.
There are two explanations of this, both quite frightening.
The first is that he really doesn’t understand this. That he doesn’t understand that the financial system has suffered cataclysmic shocks and doesn’t work the way it used to. It would inspire confidence, wouldn’t it, that an individual playing a crucial role in reshaping that financial system through the promulgation of rules under Frankendodd doesn’t understand why things are working-or not working-the way they are?
The second is that he is a fan of the band Say Anything. That he knows that his “evidence” has nothing to do with Libor manipulation, but he is saying it to advance some regulatory or political agenda.
I’m betting on the second alternative, because Gensler is a serial offender in this: look back at my posts from 2009 and 2010 and you will see numerous times where I called BS on the former Goldman managing director for making ludicrous statements about financial markets-all of which were calculated to justify Frankendodd and a massive expansion of Federal regulation of derivatives markets.
Regardless of the reason, one thing is clear: Gensler’s misleading analysis lies naked and exposed. This is not to say that Libor was not manipulated. It is to say that what Gensler hypes is not evidence of the existence of manipulation, or the magnitude of its effect.
It is unfortunate that he penned such a distorted oped, given that his agency provided a very rational proposal to reform the Libor fixing process in its Barclay’s settlement order. Gensler should limit himself to promoting that proposal, rather than writing pieces that sow confusion and promote misunderstanding about a highly contentious issue that could have huge and costly impacts on banks-and hence on the world financial system, stressed as it already is. That is not constructive. It is irresponsible and dangerous.
