巴西正继续收紧加密资产监管。根据巴西央行最新发布的第 584 号决议,自 2027 年 1 月 1 日起,虚拟资产服务提供商在处理部分大额加密转账时,需先保留资产最长 24 小时,再决定是否放行。

重点针对跨境与自托管转账

这项措施主要针对两类去向:境外加密服务商,以及用户自托管钱包。触发门槛为单笔超过 1 万美元,或同一客户在同一天内累计转账超过 1 万美元。若机构内部风控认为存在异常,低于这一金额的交易也可能进入额外审查。

巴西央行表示,新规旨在应对金融欺诈资金借助虚拟资产快速转移的情况。监管方提到,稳定币等工具近年被更频繁地用于跨境转移资金,部分资金会直接流向境外平台,或进入由用户自行控制的钱包地址。

平台需通知客户并保存记录

在新机制下,24 小时并非一律强制等满。只要服务商已完成风险核查,并满足监管设定条件,相关转账可以提前放行。因此,这更像是一道反欺诈缓冲期,而不是普遍冻结措施。

除延迟放行外,虚拟资产服务商还需履行新的操作义务,包括在转账被暂缓时通知客户,并保存与欺诈事件相关的记录。

  • 已发生的欺诈事件
  • 欺诈尝试的记录
  • 机构采取的纠正措施

2027年起多项加密监管同步生效

这意味着,巴西正把原本用于支付领域的反欺诈控制,进一步扩展到虚拟资产服务。对监管机构而言,这也为平台审查高风险交易争取了更多时间。

这项转账规则并不是单独推进。巴西央行今年 7 月已将虚拟资产服务商纳入审慎监管框架,并要求相关机构自 2027 年 1 月 1 日起遵守资本、风险管理和信息披露要求。

此外,这些机构还需在 2028 年 6 月 30 日前全部纳入更严格的第 4 类监管分组,不再按规模大小区别对待。随着这些安排陆续落地,巴西的监管重点正从基础准入,转向持续监督平台如何管理资产、转账和财务风险。

补充信息:国际货币基金组织 7 月发布的金融体系稳定评估提到,自 2017 年以来,巴西加密活动增长明显,尤其是与美元挂钩的稳定币使用扩张较快,跨境加密资金流增速已快于传统资本流动和名义 GDP。
