For anyone interested in what SBI is up to, here is their 3 month financial report ending June 30th http://www.sbigroup.co.jp/english/investors/disclosure/presentation/pdf/180731presentations.pdf
XRP is mentioned on pages (103, 108, 110, 111, 122, 127, and 132)
1) First blockchain remittence corridor(for SBI) from Japan to Thailand established and using xCurrent. We need as many corridors as possible, it will just increase the value of the network overtime. More banks, and companies will want to join RippleNet if there is a more efficient way to move money anywhere, anytime with lower costs. Great to see more remittance progress being made.
2) "SBI VC provides the narrowest spreads among spot transaction exchanges" Although it has the highest spread between the 3 digital assets listed, it's faster, cheaper and more efficient. I think with more liquidity in the market, the xrp spread will decrease even further.
3) Exploring the derivatives market! News from SBI yesterday: we are partnering with ClearMarkets. Now officially that partnership is shown in this report! This is yet another massive(but well known) use case for xrp. I'm not saying xrp will be used in every derivative to settle transactions. However, it is possible xrp could be used to settle a portion of either crypto based derivatives or a portion of all derivatives. Which, again for those of you who don't know is a market measured in the quadrillions of dollars. Maybe this all flows through codius, video below. Please recognize that this is all long term thinking, but it's shaping up to be very interesting to say the least). It's refreshing to see SBI working towards growing the xrp ecosystem along with Ripple and other developers.
