The Fed was very hands off in the early 1930s:
> […] At the onset of the Great Depression in 1929–1930, the Fed maintained a “hands-off” approach, believing the economy simply needed to “wring out its excesses.” This is somewhat ironic in that Fed policy itself greatly contributed to the financial excesses of the 1920s. Nevertheless, the Fed failed to recognize the nature of the economy.
> When the Great Depression hit in 1929, the Fed’s instinct was to do little and let the economy and markets correct. But the Fed seemed to have no sense of how big the credit bubble from the 1920s was. Consequently, from 1929–1933, the Fed remained committed to a tight monetary policy. Under the gold standard then in force, when the gold balances held by the government contracted, the money supply did so as well. Faced with the increasing economic turmoil, US businesses and the public at large trusted gold more than paper currency. Overseas investors, fearing a potential devaluation of the dollar, preferred gold too. This created a gold drain. As the Fed’s gold stocks declined, the United States unwittingly reduced credit in the economy. Over the 1929–1933 period, the US money supply contracted sharply, declining by roughly one third between 1929 and 1933, and the country experienced its worst ever downturn, with unemployment soaring to roughly 25%.

It was the interventionist policies of new New Deal and its various spending and jobs programs that helped the recovery begin. As well as getting off the gold standard:

If you think things are bad with government intervention and regulation, you may wish to examine history about things before it became a thing:

IMHO the (US) financial system has been much more stable with more of a government / Fed hands-on approach.
Certainly there were crashes (1987) and bubbles (1999), but that was more on the private sector side. At least one problem was due to not enough oversight:
People hear this and think "everyone was broke", but there literally was just no money. We hadn't fully figured out modern monetary policy at that point, and the old ideas of austerity reigned supreme for policymakers.
And yet, no. No one spoke of austerity. The government wasn't austere. Hoover's Treasury Sec., Andrew Mellon, wanted to "liquidate, liquidate, liquidate" in 1929, but that didn't happen. More government largesse than Roosevelt went with would not have resolved things, not all other things being equal.
The key thing was the Fed was (early on) complying with how the gold standard worked, which is a finite amount of cash being available, and only being able to be increased by having more of the shiny stuff.

This is one of the reason why the gold standard (or any "hard" currency) is a bad idea:

The sooner the US (and other countries) got off the gold standard, the sooner their economies started to recover:
> In the end, recovery from the Great Depression does not begin until countries give up on the combination of the Bagehot Rule and of commitment to sound gold-standard finance. Those countries that have central banks willing to print up enough money so that people are willing to spend it--it is when you adopt such policies that your economy begins to recover. If you don’t, you become France, which sticks to the gold standard all the way up to 1937, and never gets a recovery. When World War II begins, Nazi Germany’s production--equal to France's in 1933--had doubled between 1933 and 1939. French production had fallen by 15%.

There was a misstep in 1936 when there was pressure to raise rates and also to reduce spending due to deficits, and so rates were raised and austerity was enacted… and the economy tanked again.
