What is Margin Funding or Lending?
Margin funding/Lending feature goes hand in hand with margin trading. If you are not a trader and prefer safer investments, this feature is for you.
Through your exchange main wallet, funds need to be move to the Funding/Lending Wallet, Bitfinex and Poloniex allows you to provide funding/lending in any of our various funding/lending currencies to traders. You can enter offers with your own chosen terms (return rate, duration, and amount). When an offer is taken by a trader/funding taker, the money in your funding wallet will be used by the trader to buy or sell bitcoins or supported currency(open a position). When the trader completes a trade by closing the position, bitcoins are bought or sold back and the money is returned to your wallet.Margin funding/Lending interest is paid to the provider in the same currency provided.
For example:
If a trader borrows USD to long BTC, the trader pays the funding cost to the funding provider in the equivalent value of USD at the agreed upon USD funding rate.
If a trader borrows BTC to short BTC, the trader pays the funding cost to the funding provider in the equivalent value of BTC at the agreed upon BTC funding rate.
What are the risks associated with offering funding?
The risks are considered low due to the design of the underlying risk-limiting engine, the following steps taken to prevent funding providers from losing money:
If a margin trader's position is at a loss, he will cover the loss with funds in his margin trading wallet. The funds in the margin trading wallet serve as collateral. The initially required margin to open a position is 30/40% of the value of the position size. For instance, to open a long position worth $3,333 USD, an initial margin of $1,000 USD is required.
A trader's position is forced liquidated when the net value of his account falls below the required margin (15/20% of the value of the margin position). For instance, if a user with a position of an initial value of $3,333 USD and $1,000 USD collateral would lose $500 USD or more, the position will automatically be force-liquidated.
Assume the BTC price is $250 USD/BTC and you hold a balance of $1,000 USD in your margin trading wallet. This would allow you to open a margin long position of (up to) $3,333 USD worth of BTC (3333 / 250 = 13.332 BTC). The $1,000 USD in your margin trading wallet serve as collateral in case the trader loses money on the position. All additional funds needed on top of the $1,000 USD collateral in order to be able to open the position ($2,333 USD) will be borrowed from liquidity providers. The minimal required margin is 15/20% of the value of the position: 15% of $3,333 = $500 USD.
When the net value of the account reaches $500 USD, the position will be force-liquidated. This will be the case when the loss on the position is $500 USD; this happens when 13.332 * BTC price = 3333 - 500 => when the BTC price is $212.496.
Let's assume the price drops to $212.496 USD/BTC. The position will be force-liquidated: after forced selling of the 13.332 BTC @ $212.496, there will be $2,833 USD available for repaying the borrowed $3,333 USD. The losses will be covered by the $1,000 USD serving as collateral in the trading wallet. After forced liquidation, the trader will end up with a margin trading balance of $500 USD, and the borrowed $3,333 USD margin funding will have been returned to the liquidity provider.
Note that these numbers will vary due to fees and interest payments. Also, a margin call triggers a market order, so the actual liquidation price can be a bit lower than $212.496 in the example, depending on available bids in the order book. This could result in a loss a little bit greater than $500 USD, but this will never be a big difference. In theory, we will never allow this to happen, the margin trader will be able to cover all losses on his position up to the point his account's net value is 0%; that is until the BTC price drops to $174.992 USD/BTC (2333 / 13.332 = 174.992).
In the event, and this has never happened, the market would drop (or rise) so fast that the forced liquidations cannot be matched quickly enough to bids/asks in the order book, we have algorithms in place to slow down liquidation to prevent the situation from spinning out of control. In theory, these measures could still cause margin traders to lose more than the funds they hold in their account as collateral. Up to a certain point, we will cover the losses from our own reserves; however, if the price would change so dramatically that the majority of all margin positions would drop below zero, losses eventually will be shared with margin funding providers. This has never happened in the existence of our platform, but in theory, it could happen.
Providing liquidity in margin funding is not risk-free; however, interest rates are typically far higher than you achievable at through a typical savings account. In the end, it's up to the user to weigh this risk and gains.
How are interest and fees calculated when offering margin funding?
Please see below an example of how interest and fees are calculated when you offer margin funding:
For instance you have an active $10,000 USD offer at 0.06% you would earn $6.00 USD per day. On those $6.00 USD a 15% fee is charged, so $0.90 USD. You will receive $5.10 USD per day that offer is active.
This can be done manually or you have the process automated. The loan bot can be found at mycoinsbot.com
