It’s trader’s intuition. I can give you some rough data that gives me these strong hunches about the dynamics at play. Your predictive models are only as good as the assumptions you make so I will give you ones I have made and give some rough data that I think supports them.
Assumptions:
1). The vast majority of the POOL being sold each day is derived from the liquidity mining associated with USDC and DAI LMs.
2). If we reduce this reward drastically it will have a profound upwards effect on the price.
3). The upward effect will compensate to maintain the current APYs on the pools.
4). We will be getting more bang for our buck; hence diminishing returns will decline
So for starters, take the top list of addresses displayed in pooltogether for the biggest players in the USDC and DAI pools. See which ones are selling and which ones aren’t. Find the proportion and apply that profile to the entire profile of players. That seems reasonable to me. I found that 86% of DAI (skewed heavily by the 35mm depositor) and 63% of USDC POOL that’s dripped is being sold on the market. That means 0.632295.1 + 0.862295.1 = 3419.699 POOL @ 19.4 = 66,342 USD worth of POOL is on average sold each day.
The average volume on Uniswap per day over the last month is roughly 500k doing a rough eye test. That means each time this is sold and bought equates for 66,342*4 = 265,368.64 USD worth of that volume. That’s 53% worth of the volume just to maintain the price at a certain level where buyers and sellers are cancelling each other out. This doesn’t account for trading bots that are doing trading strategies or front running bots or arbitrage / rebalancing between sushiswap and other short term activities from traders, so that is a massive proportion of the volume imo. I know there are other markets listed on coingecko, but nearly all of that is fake. The real volume is on uniswap and some is on sushiswap so maybe it would be fair to have included that volume too. Anyway, back to this rough looking model.
Lets paint a hypothetical model:
You could model this, take the uniswap price action over the last 14 days or longer and assume that the liquidity miners that are selling are doing so with a reduced reward. So for example, if we cut the rewards in half farmer 1 is selling 100 POOL instead of 200 POOL. Let’s also assume that buyers behaviour does not change.You can then find out what the price of POOL would have been. Again, because all I ever do is ballpark, instead of 3419 POOL been sold to the market, what spread markup is there for only selling 1709.5. I get 1.69%. So each day, the market is 1.69% higher. Over the 2 week period, instead of the price being $19.4 2 weeks ago, it would be 19.41.0169^14 = $24.52 and 19.41.0169^30 = $32.07 after 1 month.
Of course markets don’t work like this, when the price goes up some buyers down at $19.4 will get put off buying and the buying power dissipates you could argue. You could also argue that they were accumulating down there and end up fomo’ing in once it starts rising believing they won’t be able to buy down at $19.4 again. And in reality a market doesn’t just go up in a straight line. So there are many issues with this simple model, but it does get across that a reduction in supply does lead to a significant change to the market dynamics over time. The more important question I ask is, how does that affect the mentality of the buyers in the market? We know how it affects the sellers; it doesn’t they are still selling every few days.
And finally I’ll just add, in order to keep the APY I listed above constant if we reduced the rewards in half the price would need to be $40.84.
Current: 2295.9x(20.42) / 79,779,971x365x100 = 21.449032% APY
Halving the supply and maintaining the APY
21.44903279,779,971 / (365100*(2295.9/2)) = $40.84
Certainly if I saw a signal that the rewards were drastically coming down I would be revaluing what I thought the value of POOL was on the market and I’m sure others would too. It’s clear to me, given how many times POOL has got supported in this $16-$20 price band, that the buying pressure down at $19.4 would overtime overwhelm the sellers.
