In a cashless economy there would be possible to invest into cryptocurrencies. I would imagine that hoarding, say, Bitcoins, would become popular if banks set up high negative interest rates.

@user161005 not sure if people would hoard crypto -research shows that crypto behaves like a speculative asset not as a currency-  but people would probably started “hoarding” more regular assets which is the whole point of negative intrastate rates, to get rid of the excess uninvested savings. But the negative interest rates can be very low if society is cashless - it’s also not possible that the society completely switches to some another form of money if the original money is legal tender so all taxes have to be paid with it which is what creates demand for fiat money in the first place.

@1muflon1 1. But does it mean that a cryptocurrency is UNABLE to behave as a currency? Today cryptocurrencies kind of stuck due to network effect , there is not much use in using them, but to speculate. Situation that you described would simulate adoption of cryptocurrencies on wider scale, making speculation lesser part of their circulation. 2. Okay, so there would be two currencies, one used for taxes and one for everything else. I don't see how such incomplete adoption would make much difference.

The problem is that since you still need the original currency for taxes it’s not that useful to use the 2nd currency (you could make the same story for commodity money no crypto required).

@1muflon1 1."still need the original currency for taxes it’s not that useful to use the 2nd currency" I don't see why need to pay taxes makes 2nd currency impractical. Nothing prevents a company from converting small percentage of its 2nd currency into tax-currency. 2."if you spend your money you are fine". Liquidity of commodities won't beat liquidity of money. If I want liquidity I will prefer money to money. 3."but then crypto is extremely volatile".

volatile. Also it’s not even true supply can’t be increased. Not all crypto works like bitcoin and even in bitcoin there is upper limit but the supply still can grow. Demand is additional problem with crypto.. since there is no underlaying intristic value in it you can’t be confident demand will always increase. Even if the value of crypto would empirically just always increase because demand always would it would just solidify bitcoin as investment asset - deflation is also form of price instability and high deflation gives incentive to people to not use the money as money but as investment

@Giskard I am not even 100% sure it contradicts mine. I would agree that under negative rates supply of credit will drop - that’s even the main point usually neg interest rates occur when real Int is neg. which indicates excess of saving and credit. If BBking answer is made under assumption there is cash I would not call it wrong but in cashless society there would still be credit. This is because it’s better to borrow 100 today for 90 tomorrow then having 100 today on deposit account and get 80 tomorrow due to negative interest on deposit - hence there could still be incentive to borrow

You are right that this is the reason why interest rates normally have been positive (up until now). However, for instance in fast declining populations you might envision a lot of people want to offer credit despite highly negative rates if there are no better alternatives to save.

@JonT, sure people may be willing to accept negative interest rates. I just don't think it is realistic that it will ever happen. Realistically, the worst way to save will remain to keep your money in your bank account at 0% interest, which will always be better than negative interest. Declining populations will not change that.

@BBKing but at negative interest rates in cashless society also deposit interest rates would be negative! In fact even in Netherlands at some banks the interest rate on some deposit account (above 1000000e) the interest rate is already negative and we are not even completely cashless (which why banks applied it to only accounts with over 1000000e because where will you take that heap of cash?). If there is negative interest on your deposit account you still want to invest in bonds etc which at least offer less negative interest than deposit - it’s like a mirror image of normal situations

Yes, but very large negative interests (not minor ones as the OP suggests) would eventually imply negative borrowing rates, which could lead to almost infinite demand for loans in a market that could not clear. Especially with the competition we see in banking today, I simply don't see highly negative deposit rates and interest rates as realistic. In a cashless society there are also no costs to storing cash (which could be a rationale for negative deposit rates).

Not the same question, but it sort of answers my question. Thanks. The questions link to an IMF blog article which says that the lower bond on interest rates can be solved by removing cash or splitting electronic money and normal cash into two currencies and let the hard currency float. So I guess that implies that IMF think that the main constraint for negative rates are hard cash.
