The Trump administration put sanctions on a Turkish bank.

The bank's name is Golden Global Yatirim Bankasi Anonim Sirketi.

The U.S. says the bank is a "critical financial lifeline" for Iran.

This action is part of a new U.S. effort.

The effort is called "Operation Economic Outcast."

It wants to separate Iran from its trading partners.

Treasury Secretary Scott Bessent started this operation last week.

The Treasury Department said the bank is in Istanbul.

The bank was set up to help Iran move oil money.

The money moved from China to Turkey.

In Turkey, the money could become cash and gold.

The bank also gave services to Iranian money groups.

Some of these groups got U.S. sanctions in 2022.

Bessent said money groups tied to Iran will learn a hard lesson.

He said the U.S. is serious.

He added that more sanctions depend on other countries.

They must stop supporting the "murderous Iranian regime."

But the big plan has not worked much so far.

The plan wants Iran's trading partners to stop.

The U.S. did not punish big partners like China and India.

Instead, it gave warnings and talked with them.

The sanctions came one day after a Turkish bank settled a U.S. case.

The bank is Halkbank.

It is state-run.

The case lasted nine years.

It was about Iran sanctions.

Officials moved about $20 billion in Iranian oil money.

The U.S. also started military strikes on Iran again.

This happened recently.

The result of this two-part plan is not clear now.
