> How does this chart [0] show a debasement of any sort?

It's the gigantic jump in the blue line almost halfway between 2008 and 2010. A spike in the value of "all assets" is the definition of currency devaluation.

Hey, sorry for not providing more context, the blue line is the Fed's balance sheet and the red line is inflation.

Yes, the Fed's balance sheet skyrocketed, but inflation (the value of money vs. goods & services) remained lower than before that line spiked.

So why did they stop growing their balance sheets then?

RC_ITR 1593 days ago

Because QE is an active tool to support credit liquidity and they determined that markets were liquid enough to remove that support.

EDIT: And just to be very clear to the 2 people who read this comment, maintaining a balance sheet is still market support b/c you still buy treasuries on the open market to offset the principle of your existing treasuries that reach maturity. So stopping the growth of the balance sheet just means you're not accelerating support. Tapering is the thing that you do if you're worried that your balance sheet is 'debasing' the currency.

> Inflation was strongly negative

It's not clear to me if you're talking about monetary or price inflation.

> some economists have interpreted price inflation as a desperate method by which the public, suffering from monetary inflation, tries to recoup its command of economic resources by raising prices at least as fast, if not faster, than the government prints new money.

Only the long-debunked Austrian school defines inflation as a function of supply alone. The rest of the world moved on to defining inflation in terms of the measured, real-world change in the purchasing power of money - which comes under pressure from a number of different factors that aren't captured by supply.

For instance, supply chain disruptions making basic goods more expensive and increasing competition for them. Or, zoning policy prohibiting construction of new housing sufficient to meet demand in high-growth metro areas raising the cost of housing. Or zoning policies in suburban areas making housing 2x bigger on average now than in the 1970s. [1]

Defining inflation as a function of supply distracts us from the real-world problems causing broad-based increases in price.

lol.

price is a function of supply and demand already. you don't need to redefine inflation unless you're trying to dupe feeble-minded rubes.

Purchasing power is a function of a whole ton of things, including supply chains. If goods require more inputs or are less efficient to produce that will increase their price. This in turn decreases the relative purchasing power of a dollar. This can happen due to all sorts of externalities, for instance a tax. Or it can go down due to efficiencies in manufacturing technology or biotech. Or, a massive global pandemic leading to supply chain disruptions can cause prices to go up. Or housing can become more expensive because of zoning rules.

The "supply of currency units" is a fundamentally inadequate measure to capture this. It is too simplistic. Nobody takes it seriously except for a small group of very vocal online crackpots because it is so obviously unfit for purpose. [1]

We re-defined it as our understanding grew. The way we update practically any model in the face of new evidence.

Japan single-handedly demolishes the Austrian model. Their M2 supply grew 3X from 1990 to present but inflation remained 0% measured over thirty two years. Prices did not change from 1990 to 2022. [2, 3]

you're again conflating price and monetary inflation. and again mixing in somebody else's prejoratives to flavor your discussion of their topics.

here's a link [1]

No, I'm not. The idea that supply increase is inflation is a rejected Austrian economics concept with no basis in reality.

> An increase in supply is not a debasement. That is measured post-facto based on its impact.

An increase in supply is always a debasement.

It's true that you might see the following chronology:

1/1/2020: value of the currency measured

6/6/2020: supply of the currency increased

1/1/2021: value of the currency measured; it's higher than it was last year!

But that doesn't mean the issue on 6/6/2020 wasn't a debasement. It definitely was, and the reason it doesn't look that way is your very low-resolution measurement of value. If the supply increase hadn't happened, the value on 1/1/2021 would have been even higher.

An increase in supply alone isn't debasement. A higher supply doesn't imply a lower value, because what you do with that new supply matters. If you mint a $10T coin and throw it under your mattress, then you haven't decreased the value of anything even though the supply has increased dramatically.

This is why we measure, and why Austrian economics fell out of favor decades ago.

See Japan for a concrete example. [1, 2] Their M2 money supply is almost 2.5X higher since 1990 but their CPI is dead flat over the same time period. It's actually seriously problematic for them.

> If you mint a $10T coin and throw it under your mattress, then you haven't decreased the value of anything even though the supply has increased dramatically.

How has the supply increased in this scenario? What if, instead of minting the coin, you just tell people that you've done so?

The supply of money has only increased if you're able to spend the putative addition to the money supply.

You can tell them all you want, but as Japan shows us, it doesn't actually matter. What matters is what you do with the supply which is why we measure.

Let's focus on the opening question, "how has the supply increased in this scenario?".

I'm sorry I don't understand the question.

Are you asking how supply works in my hypothetical, simplified example where the point I'm trying to make is that new supply in isolation doesn't matter - what you do with it does?

Or as you asking how it happens in the real-world example of Japan, where their supply increased from 400000B JPY to 1200000B JPY between 1990 and present, while everything remained the same price? And how this is seriously problematic in their economy?
