Remember that an increase in M1 doesn't mean "more money for everyone"! It just means more reserves for banks.

I think the key thing here is to look at is increase of bank deposits (I.e. money for you and me). That is M2 MINUS central bank reserves and notes and coins in circulation. If you look at this you'll see that bank deposits have only increased modestly despite the large increase in M1. From this you can infer that the FED's "money printing" isn't really affecting Main Street very much. I.e. currently not causing much inflation.

What's happening? The FED is creating new reserves and using those to buy bonds. The reserves remain in financial institutions and should incentivise banks to lend - or at least that is the theory. Lending is how bank deposits (money for you and me) are created. The reserves which the FED creates to buy bonds (which are assets of commercial banks) doesn't end up in people's Bank accounts (which are liabilities of commercial banks). Instead, the reserves remain sloshing around in the banks.

My view is that money supply is endogenous. That is, new bank deposits are created when new loans are made. Currently, there is not a demand for loans so there won't be a huge increase in the M2 money supply as a result of these FED bond purchases. Perhaps demand might increase in the future, in which case the US will see inflation. I suspect once the economy recovers and inflation (as measured by the FED) increases then they'll start performing open market operations to sell the bonds they bought and thus remove the excess reserves from the financial system.

Doesn't M1 exclude bank reserves?

Edit: Indeed. M1's definition: "M1 includes funds that are readily accessible for spending. M1 consists of: (1) currency outside the U.S. Treasury, Federal Reserve Banks, and the vaults of depository institutions; (2) traveler's checks of nonbank issuers; (3) demand deposits; and (4) other checkable deposits (OCDs), which consist primarily of negotiable order of withdrawal (NOW) accounts at depository institutions and credit union share draft accounts. Seasonally adjusted M1 is calculated by summing currency, traveler's checks, demand deposits, and OCDs, each seasonally adjusted separately.

I agree with this line of argument for the 2008 era quantitative easing! But my read is that M1 explicitly excludes bank reserves, so the M1 created can't be locked-up reserves, right?

Gosh, you are right (and I'm completely wrong). I've royally messed up my money definitions. What I meant by M1 was actually M0... Or the base money supply. It also seems that each country uses the same MX symbols but they mean different things in different countries. I've got the graphs on the FED website now and it seems that bank deposits have increased a shit load. Probably due to the recent "stimulus" measures.

It seems the FED did increase base money supply - it's balance sheet size went up by around 3 trillion dollars at the start of 2020 - and bank deposits have subsequently increased quite a lot (M1 and M2 gone up) and this is probably due to the stimulus measures because either way the money ends up in someone's bank account. I think also some of it is probably due to risk averse businesses maxing out their credit lines to get them through the lockdowns... so we'll see an increase in M1/M2 there as well.

So whilst the first part of my original comment was wrong because of the incorrect definitions and reasoning, I think the second part accidentally remains true, in that we should, in theory, start to see inflation increase and from that point you would expect the FED to start removing excess reserves from the system and tightening things up a bit.

Totally understandable! hah I did like three loops through the different definitions to straighten myself out before I got the confidence to reply back. Tricky and inconsistent definitions indeed.

I'd also like to celebrate that we can have learning exchanges like this on HN! That's awesome. Thanks for all the great things you've brought to the conversation rojeee!

Plus, nothing like that with a dose of zero-indexed irony :) Looks like CS isn't alone in the zero-indexed world.

[rojeee]

Sorry about that! Yes, I agree, it's quite nice to be able to have such conversations.

If you want to learn more about the modern monetary system I would recommend doing Perry Mehrling's - "Economics of money and banking" course. It's on Cousera but some of the lecture notes are available here [0]. Thoroughly recommend it! Cheers
