A senior IMF official (not a child in work experience) with the remarks:

• Recent Yen Drops Driven by Fundamentals, No Reason to Change Japan’s Economic Policy
• no need to change the accommodative monetary policy of the BOJ

The official was asked if an intervention to buy yen would be justified, said no:

• we do not see disorderly market conditions in the forex market

Sheesh, anyone with a brain cell pointed out the monetary policy divergence between the BOJ (super-easy) and Federal Reserve

Federal Reserve

The Federal Reserve System, more commonly known as the Fed, represents the central banking system of the United States. Like other central banks around the world, the Fed is responsible for monetary policy, in this case in the United States. The Fed is one of the most watched and followed entities for forex traders, given its large impact on the US dollar. Originally founded in 1913, the Fed was created to perform a wide range of functions. This includes stabilizing and maintaining flexible monetary policy in the United States while strengthening a financial system for the country. Its general functions are to set and guide monetary policy and oversee the efficient functioning of the economy, both of which serve the public interest. by the Federal Reserve Board of Governors. The current interest rate and expectations of future interest rate changes can influence the value of the US dollar. For example, if traders anticipate a change in interest rates based on announcements from the Board of Governors, this may cause the US dollar to appreciate or depreciate against other currencies. Forex traders should always be aware of Fed meetings and announcements and should follow developments within the central bank. Ultimately, the Federal Open Market Committee (FOMC) holds eight regular meetings per calendar year, where policies and interest rates are discussed and agreed upon. The best course of action is to stay on top of the news ahead of these meetings as a forex trader to make predictions on interest rates and whether to buy or sell the US dollar.
