瑞波与罗宾汉达成合作，扩大RLUSD数字美元的应用规模
可以写进 IB、A-Level、AP、IGCSE 经济学论文的真实新闻案例：金融市场与银行、信息不对称与市场失灵
发生了什么
瑞波与罗宾汉达成协议，推广瑞波发行的数字美元RLUSD，为机构客户提供更多交易与融资选择，并改善罗宾汉自身的资金管理。
经济学角度
这体现了金融市场的创新与中介功能：新的支付与结算工具（稳定币）进入交易平台，可降低机构客户在交易和融资中的结算摩擦，也改变平台内部资金调度的方式。同时，数字美元的价值依赖发行方储备与赎回承诺，属于信息不对称问题，投资者难以完全核实其背后资产。
评估角度
短期内合作可扩大RLUSD的使用场景并提升平台资金效率，但稳定币的信用取决于发行方储备透明度与监管，若信任受损可能引发赎回压力；受益者主要是机构客户与平台，普通用户承担的风险未必同步下降。

English version
What happened
Ripple and Robinhood have agreed to promote RLUSD, Ripple's digital dollar, giving institutional clients more trading and financing options while improving Robinhood's own treasury management.
The economics
This illustrates financial-market innovation and intermediation: a new settlement instrument (a stablecoin) entering a trading platform can reduce settlement friction for institutional clients' trading and financing and change how the platform manages its own funds. At the same time, the digital dollar's value rests on the issuer's reserves and redemption promise, an information asymmetry problem since holders cannot fully verify the backing assets.
Evaluation
In the short run the partnership can widen RLUSD's use cases and improve the platform's funding efficiency, but the stablecoin's credibility depends on reserve transparency and regulation; if trust weakens, redemption pressure could follow. Institutional clients and the platform gain most, while ordinary users' risks may not fall correspondingly.
Practice question
Using this example, analyse how financial innovation such as stablecoins affects the efficiency and risks of financial markets.
