But it's not just the rate with the central bank, they're forcing high street banks to prove that their systems can handle negative interest rates for consumer loans and mortgages.

It's obvious that it doesn't work. In order banks be able to lend money it's necessary the existence of business and households that want to spend money instead of saving.

What we are seeing, is the result of using the wrong tool, monetary policy instead of fiscal policy, because ideological reasons.

That’s the idea, yes. But it should be pretty obvious that it doesn’t work, for the same reasons QE doesn’t. Because banks can’t actually ‘loan out from reserves’ to their customers (they can loan reserves to other banks, but can’t to anyone who doesn’t have an account with the central bank). It actually can’t be made to work in terms of accounting operations. The role of reserves is settling transfers, so the bank obviously needs to have them as part of the process, but that happens later, after the loan is written (which creates the asset (loan) and liability (deposit) on the bank’s balance sheet). So having excess reserves doesn’t really increase the bank’s ability to extend more loans anyway, and taxing reserves just makes the bank want to buy more equities to get a positive rate.

It's when, despite low/negative rates, borrowers prefer to hold cash than to take out loans.

The biggest problem is that the things people want to buy are in short supply. So the extra money doesn't actually help anything, you just get asset price inflation.

I want to buy a house. If everyone has access to cheap mortgages, then everybody can buy a house! But there is a hard limit on how fast we can build housing. Even renovating a home has the same problem. Contractors in my area are raising their hourly rate now because everybody wants their home renovated! But there aren't enough contractors for everyone, so the price just goes up.

Look at the video card market. There's a hard limit on the amount of video cards that the industry can produce. That doesn't change if suddenly everyone can afford the $2,500 price tags. The price just goes up by exactly the amount of money people get loaned!

And there's a hard limit on the amount of entertainment I can consume in a day. A person has about 16-20 hours a day MAX to consume media. We literally can't listen to any more music, there's not enough time in the day. I can't spend any more money on media because I am physically unable to consume more.

I don't see how this would stimulate anything? The reason I'm not buying anything isn't because I can't afford it, it's because it's not available at all! (Probably why the stock market is experiencing volatility right now - it's the only thing providing utility right now)

You say that, but this is already happening in some places: https://www.theguardian.com/money/2019/aug/13/danish-bank-la...

They're trying to avoid retail deflation. That is not usually related to asset deflation.

Asset inflation has been raging for at least a decade, maybe 2, inflating stock assets, housing and commodities, bitcoin and anything else which promises some return to unseen levels, since they started QE and dropped the low risk rate of return to 0. Retail inflation which they're trying to control is pretty much unaffected by QE and ZIRP and whatever levers they are pulling are not working, they just haven't noticed yet.

So at this point, if someone offers you free money, you say thanks very much and put it in the stock market, like everyone else, because where else can you get a return? And that goes on until the whole thing explodes in a panicked crash when public pretension differs too much from private reality.

Oops.

If someone gives me a $10M loan at -1% interest, I would spend $200 on suitcases and a vacuum sealer kit and $200 to hire a mini-digger. I'd then go dig a 6 foot hole in a forest somewhere and hide the money as cash. I'd install some weather stations around the site with PIR sensors and 4G ($25 each, x4) just to see if someone comes hunting for my cash.

After 5 years, I return the cash. I earn $500k. Subtract off the $500 it cost me to set up and that's a pretty tidy profit for 2 days of my time. The chance of theft is well under 1% as long as nobody else knows where it is, so I still make a tidy profit even with a risk premium.
