The bank has seen the transaction and its flagged up a commonly used money laundering pathway. They constantly monitor accounts , some more than others. You may be one of hundreds of “money washing machines “ that is being used. They are probably monitoring a known route.
A few years ago my business account was put into a “ special department” I only found out when I had a mortgage (simple remortgage) refused at the last minute. My financial advisors rang me in a panic because there was no explanation. He had been given a number for me to contact, I rang them and a very pleasant manager explained my account was in this special dept ( I don’t remember the actual name) and was being investigated. I ask why and he said he could not disclose because it wasn’t my account that was under investigation, but one I was associated with.
I had a joint account with my DSis at the time so asked if it was her account he said no, since she had joint accounts with her DH I asked if it was my BIL. He said he could neither confirm nor deny ( his actual words), but he could say it wasn’t my DSis.
Since the main problem was the remortgage, I asked him if I severed the connection would they lift the sanctions on my accounts. He said yes.
Anyway after a heated discussion with my DSis, who didn’t believe me she agreed to take herself off the joint account and after many phone calls my financial advisors rang rang me to say they’d reversed the decision on the mortgage and it was going through. He was astounded since he’d never known them reverse a decision.
Now this was where it became a little weird. I rang my bank manager, who I knew quite well. His first comment was he’d just had my account returned to him ( I presume virtually since it’s all digital) he then said that he didn’t know that it had been removed from his department. I then told him the full story and even he didn’t know about the department it had been transferred to.
The manager reassured me that it hadn’t been tagged so I shouldn’t have problems in the futures and apologised profusely. Neither of us would have ever known about the special department if it hadn’t been for the mortgage debacle.
DSis and I made up, I explained that the last thing I needed was having my business account being restricted, wages and bills were due and it would have been a nightmare. She had done a bit of digging and her DH was in a lot of debt ( alcoholic, out of work spendthrift), they were on the verge of divorce anyway, and he wouldn’t explain what had happened. He claimed the special department had got it wrong. To this day he claims it was nothing to do with him. But his situation at the time was dire and I suspect he was about to assist in a money laundering scheme in order to earn some money.
My misfortune was having a business account that was linked via 3 accounts to BILs, my personal account, joint account with DSis and joint account DSis and BIL had. I suppose the bank automatically thought that it was a network of personal accounts between which money could easily be transferred. The transfer that triggered the cascade may well have occurred but BIL never disclosed what happened.
I spoke to my DH’s DB who was in police intelligence at the time and he agreed that in all likelihood the money was whatever BIL was up to had flagged potential money laundering and they’d shut down our little network of accounts but we were able to use them despite them going into “special “ department. Unfortunately, the big red flag that was attached to the network and security refused the mortgage at the last minute.
The manager in the “special “ department was lovely and without his cryptic help it saved us a lot of hassle.
