The USD/JPY is considered the 2nd most liquid currency pairing in the FX markets, accounting for 13% of total transaction volume in the FX market. Japan's current account surplus supports its safe haven status. During periods of political and / or economic uncertainty, the Yen is the market's preferred choice. Monetary policy and trade dynamics are also key drivers for the pairing. Historically, carry trades have also been a key influence, with the Yen a funding currency.
