What is the supply of XHV and xAssets?

Because of the unique 'mint & burn' process with Haven the supply of XHV and all other xAssets will fluctuate according to demand. If $1Million xUSD gets minted then the same USD value of XHV has to be burnt in order to create that xUSD.

At the time of launch of the first xAsset (xUSD) there was approximately 13 million XHV. As Haven is PoW there are a certain number of new XHV being created as mining rewards with a maximum of 18.4 Million plus tail emission. Haven follows the same emission schedule as Monero.
