US interest rate, and exchange rate of Japan Yen and Korean Won

The trend of Japanese Yen and Korean Won within most of year 2022, as can be observed when reading together with the chart of USinterest rate, show how closely linked their relationship are.
Recently government of relevant countries have been attempting to change this situation by putting money into the foreign currency exchange market, but as long as interest rate of each of those countries aren't increasing accordingly, and US interest rate still keeping up, no change in this trend is expected.
