What’s it with September and October being weak months for shares?  Has this at all times been the case?

Sure. Probably the most intense panics on Wall Avenue have tended to happen through the late summer time and early autumn months. This may be traced all the way in which again to the 1800s. A number of notable examples of outstanding panics embody Black Friday of 1869, the Panic of 1873 and the Panic of 1907.

However why September and October?

It’s a byproduct of an previous weak spot within the U.S. monetary system.  Previous to the reintroduction of a central banking system with the passage of the Federal Reserve Act of 1913, the U.S. was restricted in its potential to regulate the cash provide in response to market situations.

The inelasticity of the U.S. foreign money made the late summer time and early autumn months an particularly precarious time, as a result of agricultural financing cycle. Within the 1800s, the U.S. financial system nonetheless relied closely on agricultural manufacturing.  For the primary eight months of the yr, American farmers had a restricted want for capital, so extra funds held on deposit in state banks have been shipped to New York banks or belief corporations to earn the next price of return.

When harvest time arrived in August, state banks started withdrawing their capital from New York, as farmers drew on their accounts to fund transactions required to ship crops to market.

The agricultural financing cycle created persistent shortages of money in New York Metropolis through the autumn months. If these shortages occurred to coincide with a monetary shock, there was little flexibility within the system to stop a panic. 

How did the federal government reply to those panics?

The restricted potential of the federal government to react was the first impetus for the passage of the Federal Reserve Act of 1913. The Act granted the Fed the facility to function a lender of final resort throughout monetary crises. Previous to the Act, main financiers (most notably J.P. Morgan) have been compelled to assemble advert hoc options that relied totally on non-public capital. After the U.S. barely prevented a catastrophic collapse of the monetary system through the Panic of 1907, there was simply sufficient political help for the return of the third and last iteration of a central banking system in america. 

Did the creation of the Federal Reserve present extra stability to markets? 

Sure, and if one compares the frequency, depth and distress of monetary panics through the 1800s, that is plainly evident. In equity, the Fed made just a few errors alongside the way in which, with probably the most notable being its failure to cease the contagion of financial institution failures within the Nineteen Thirties. However, by and enormous, the U.S. monetary system has been way more secure for the reason that Federal Reserve grew to become operational in late 1914. 

Nonetheless, the U.S. financial system just isn’t primarily agricultural anymore.  Why are September and October nonetheless weak months?

Individuals are likely to worry issues which have occurred earlier than even when they do not bear in mind the origin of the worry. It might be that the autumn panics have repeated so many occasions that they’ve change into a self-fulfilling prophecy. In different phrases, folks anticipate them, and since they anticipate them, they behave in methods (i.e., decreasing danger in late summer time and early fall) that make them extra possible. I do know this appears like a stretch, however it does appear to be it could truly be actual.
