交通银行被风控是指交通银行对某些账户或交易进行风险控制，以保障资金安全和合规经营。风险控制（Risk Control）是指针对不同类型的风险，采取不同的措施和方法，降低风险发生的可能性或减少风险发生后所造成的损失。

交通银行作为国内知名的商业银行之一，为了防范金融风险和维护金融市场稳定，采取了一系列的风险控制措施。这些措施包括对某些账户或交易进行限制、审核或监管，以避免或减少风险的发生。

一般来说，交通银行被风控的原因可能包括以下几种情况：

账户异常：如果交通银行检测到某个账户存在异常情况，例如频繁的大额转账、交易对手信息不明确等，银行可能会对该账户进行限制或审核。

资金来源不明：如果交通银行发现某个账户的资金来源不明，或者资金涉及违法犯罪活动，银行可能会对该账户进行风险控制。

风险预警：如果交通银行收到其他金融机构或监管机构的风险提示或预警，银行可能会对涉及的账户或交易进行风险控制。

交通银行被风控可能会对账户持有人的资金使用带来一定的影响，但这是为了保障整个金融市场的稳定和防范金融风险。如果账户持有人认为银行的风控措施存在不当之处，可以通过合法途径进行申诉或维权。
