Back to the Fed Future, or You Had One Job

In the Gilded Age, American financial crises (“panics,” in the lexicon of the day) tended to occur in the fall. Agriculture played a predominant role in the economy, and marketing of the new crop in the fall led to a spike in the demand for cash and credit. In that era, however, the supply of cash and credit was not particularly elastic, and these demand spikes sometimes turned into panics when supply did not (or could not) respond accordingly.

The entire point of the Fed, which was created in the aftermath of one of these fall panics (the Panic of 1907, which occurred in October), was to make currency supply more elastic and thereby reduce the potential for panics. In essence, the Fed had one job: lender of last resort to ensure a match of supply and demand for currency/credit, when the latter was quite volatile.

This week’s repospasm is redolent of those bygone days. Now, the spikes in demand for liquidity are not driven by the crop cycle, but by the tax and corporate reporting cycles. But they recur, and several have occurred in the autumn, or on the cusp thereof (this being the last week of summer).

One of my mantras in teaching about commodities is that spreads price bottlenecks. Bottlenecks can occur in the financial markets too. The periodic spikes in repo rates–not just this week, but in December, and March–relative to other short term rates scream “bottleneck.” Many candidates have been offered, but regardless of the ultimate source of the clog in the plumbing, the evidence from the repo market is that there are indeed clogs, and they recur periodically.

The Fed’s rather belated and stumbling response suggests that it is not fully prepared to respond to these bottlenecks, despite the fact that their regularity suggests that the clogs are chronic. As the saying goes, “you had one job . . . ” and the Fed fell down on this one.

And maybe the problem is that the Fed no longer just has one job, and it has shunted the job that was the reason for its creation to the back of the priority list. Nowadays, the Fed has statutory obligations to control employment and inflation, and views its main job as managing aggregate demand, rather than tending to the financial system’s plumbing.

This is concerning, as dislocations in short-term funding markets can destabilize the system. These markets are systemically important, and failure to ensure their smooth operation can result in crises–panics–that undermine the ability of the Fed to perform its prioritized macroeconomic management task.

One of the salutary developments post-crisis has been the reduced reliance of banks and investment banks on flighty short-term funding. The repo markets are far smaller than they were pre-2008, and the unsecured interbank market has all but disappeared (representing only about .3 percent of bank assets, as compared to around 6 percent in 2006). But this is not to say that these markets are unimportant, or that bottlenecks in these markets cannot have systemic consequences. For the want of a nail . . . .

Moreover, the post-crisis restructuring of the financial system and financial regulation has created new potential sources of liquidity shocks, namely a supersizing of potential demands for liquidity to pay variation margin. When you have a market shock (e.g., the oil price shock) occurring simultaneously with the other sources of increased demand for liquidity, the bottlenecks can have very perverse consequences. We should be thankful that the shock wasn’t a Big One, like October, 1987.

Hopefully this week’s tumult will rejuvenate the Fed’s focus on mitigating bottlenecks in funding markets. Maybe the Fed doesn’t have just one job now, but this is an important job and is one that it should be able to do in a fairly routine fashion. After all, that job is what it was created to perform. So perform it.

  1. “Spreads price bottlenecks.” This is on a par with Chomsky’s “Colorless green ideas sleep furiously,” in other words completely meaningless. Please re-phrase in intelligible English.
