The Federal Reserve stated in a statement today that it will prohibit policy makers and senior officials from purchasing personal stocks and bonds, and will restrict active trading. Buying or selling securities requires 45 days' prior notice, and such transactions require prior approval and investment holding for at least one year.

In addition, the Federal Reserve has stated that it will not allow any buying or selling during periods of heightened financial market pressure. Senior Federal Reserve officials, including regional Fed chairpersons, Fed directors, and senior staff, will only be able to purchase diversified investment vehicles such as mutual funds.

Although the existing regulations have certain limitations, they still allow officials such as regional Fed chairpersons to buy and sell stocks. Twelve regional Fed chairpersons will be required to publicly disclose financial transactions within 30 days.

There is also news coming from the US and Europe. On October 21st local time, the US Treasury announced that the US will lift punitive tariffs on products from Austria, France, Italy, Spain, and the UK.

According to the agreement, the United States, the United Kingdom, France, Italy, Spain, and Austria agreed to "transition from the existing digital service tax to a new multilateral solution, and promised to continue discussing this issue through constructive dialogue. The United States has agreed to waive punitive tariffs on the five European countries mentioned above.

European countries will temporarily retain the "digital service tax" that angers American companies and government officials. If the new global tax system takes effect within the next two years, these countries will provide tax credit policies, which in effect amounts to refunding technology companies' overpayments in the event of early implementation of global tax agreements.
