What moves the Japanese yen (JPY)?
By Charu Chanana, Market Strategist at Saxo
USDJPY is one of the most popular FX pairs traded globally. Policy divergence between the US and Japan has widened since the hawkish Fed shift, and carry trades became even more attractive. However, policy expectations both for the Fed and the Bank of Japan continue to play on the minds of traders, while recession and intervention risks also cloud the outlook. This has spurred huge volatility, and the upcoming BOJ meetings could remain very interesting.
The Japanese yen (JPY) is the third-most traded currency in the foreign exchange (forex) market after the US dollar and the euro, as well as an important reserve currency. Yen traders have had a wild ride recently with USDJPY rising from 110 to 150 during the inflation scare of 2022, which prompted a few rounds of currency intervention by the Japanese authorities in late 2022 and a hawkish tilt from the Bank of Japan (BOJ) at the December meeting. Since then, traders have been waiting for more hawkish signals from the central bank but continue to be disappointed. In the article, we will look at some of the factors that drive the biggest moves in yen.
Carry trades amid yield differentials
Japan has maintained very low interest rates for many years, and that has made JPY as the funding currency of the world. That means people can borrow yen cheaply to buy higher-yielding dollars or other currencies and seek higher interest rates in instruments such as Treasury bonds to boost their returns. This has led to a close relationship between the Japanese yen and US Treasuries. When yields on Treasury bonds rise, yen tends to weaken relative to the dollar. As long as the differential between Treasury yields and Japanese yields (which are fixed) continues to widen, there will be downward pressure on the yen.
BOJ policy expectations
Changes in central bank policy always plays on the minds of currency traders. More importantly, expectations of changes in central bank policy are key and usually influenced by economic growth, inflation, wage growth and other high frequency data. If data supports a stronger economy, market participants expect monetary policy could be tightened and that results is stronger currency.
The BOJ is the only major central bank to engage in outright yield-curve control, buying 10-year Japanese bonds to cap yields at 0.5%. Recent inflation trends in Japan have turned a corner, with inflation rising to over 3% YoY levels after years of deflation. This return of inflation suggests scope for some of the stimulus from the Japanese economy to be removed to avoid overheating, and that leads to expectations of a stronger yen. However, Japanese authorities continue to view the current inflationary pressures as temporary and import-driven, and have been resisting the pressure to normalize monetary policy.
With the yen at a historically low level against the dollar, the Japanese people have been left with a difficult choice to either continue to hold their savings and investments in the yen, or move money into foreign currencies. Banks have noted a surge in the latter and this could also prompt a re-think of the easy monetary policy. If that happens, the yen will likely strengthen, but be prone to significant volatility.
Any signs of BOJ tightening could lead to massive liquidity drain on the global economy as the carry trades that use the Japanese yen as the funding currency could start to be reversed. This explains market’s nervousness.
FX interventions
Interventions mean the government and central bank actively buying or selling in the open market to push the currency in the desired direction. Such interventions are unorthodox for developed economies, and last year Japan engaged in currency intervention for the first time in 24 years. Usually, results of interventions are also short-lived.
Historically, Japanese authorities have had a preference for a weak yen as it boosts exports and the industrialization of the Japanese economy. Therefore, interventions have mostly been seen when the yen became too strong. However, the most recent episodes of yen intervention in 2022 were intended to strengthen the yen after steep weakening. A lot of Japanese companies have also now shifted their production overseas and that means that a weaker yen isn’t benefiting export companies as much as it once did. Japan is also reliant on importing a lot of resources, mainly energy, and a very weak yen makes that expensive. Moreover, authorities usually intervene not because of a particular level that the currency has reached, but more if the pace of movement in the currency has been steep.
The Japanese yen is currently holding near a 7-month low against the US dollar and close to levels where intervention was seen last year. If the yen weakens again in response to a rapid rise in Treasury yields, currency intervention concerns could grow and that limits the scope for further yen selling. Recent US move to remove Japan from currency intervention watch list has also opened up further scope for the Japanese authorities to intervene without being labelled as a manipulator. Still, ammunition is likely to be preserved until USDJPY reaches closer to 145.
Safe-haven status
The Japanese yen is also considered a safe haven in times of economic or geopolitical stress. This means that the yen rallies when equity markets come under pressure, and it is therefore used for de-risking portfolios when economic conditions are expected to worsen. What made yen being tagged as a safe haven was the fact that Japan invests in high-risk bonds outside the country, and when conditions deteriorate, they can sell those bonds and convert to yen which creates a massive demand for yen and makes it strengthen. The yen is also very liquid so can be traded easily and is generally backed by a stable government.
