JPY Monthly

October in review

The USD/JPY opened the month at 144.80. The pair remained range-bound just below 145 from end-September through early October, with the intervention by Japanese authorities at this level on 22 September still fresh in mind. The USD/JPY rose as the dollar strengthened across the board, approaching the 22 September high of 145.90, following a series of hawkish comments by Fed officials and better than expected US employment data announced on 7 October. The pair broke past this level on 12 October and rose to around 146, then advanced to nearly 147 after BOJ Governor Haruhiko Kuroda said the Bank would maintain its easing policy. The USD/JPY then shot up to around middle of-147 level on 13 October following a stronger than expected US CPI print for September. On the 18th, the dollar strengthened across the board on the back of rising inflation expectations in the University of Michigan survey, and the USD/JPY rose to above middle of 148 level, breaching the 1998 high of 147.64. It then gradually advanced toward 150. During this period, Prime Minister Fumio Kishida and other Japanese authorities repeatedly tried to jawbone the yen higher but made no major moves, and the USD/JPY reached 150 on 20 October along with a rise in US interest rates. The pair continued to rise on October 21, climbing to 151 as US interest rates came under stronger upward pressure after foreign players entered the market and looked set to test 152. However, both US interest rates and the USD/JPY stopped rising following reports in a US newspaper that the FOMC might talk about adjusting the pace of rate increases at the November meeting. A few hours after this, the USD/JPY suddenly started to fall, plunging back to the 146 level. Some media outlets reported that the government would intervene in foreign exchange markets, but Japanese authorities refrained from commenting on the matter. The pair subsequently rebounded to 148 on the same day. On Monday 24 October, the USD/JPY rose past middle of 149 level0 early in the morning but quickly dropped to the 145 level before the start of trading in Tokyo. However, it then see-sawed back to 149 before weakening again along with a decline in US interest rates following a weaker than expected US PMI and shift to dollar selling. The USD/JPY fell back to the 145 level on 27 October, then made a comeback on the 28th with the dollar strengthening as the decline in US interest rates paused. BOJ Governor Kuroda's post-meeting press conference drew attention after the London market opened, as did the employment cost index announced in US trading hours, which remained high. The dollar strengthened and the USD/JPY pushed past middle of 147 level. The USD/JPY had recovered to above 148 at the time of writing this report on 31 October (Figure 1).

The dollar's strength has subsided due to the halt in the rise in US interest rates, partly due to reports in US newspapers, and easing of political instability in the UK with the change in prime minister. Meanwhile, OPEC Plus decided to cut production in anticipation of a near-term decline in demand. Crude oil prices have stopped falling after intermittent declines since June. Partly due to these changes in the environment, the Norwegian krone and the sterling strengthened markedly in October (Figure 2).

First yen-buying intervention in 24 years had some impact

On the evening of 22 September, the MOF announced that it would conduct a yen-buying currency intervention. The rise in the USD/JPY had gained momentum following the FOMC meeting on 21 September, the BOJ's monetary policy meeting on 22 September, and especially around the time of Kuroda's post-meeting press conference. It broke past its most recent high to reach 145.90, then fell back suddenly after 17:00 JST. Shortly after that, MOF’s Kanda announced that the government did intervene in the currency market and the USD/JPY fell by over five yen to 140.40 early in US trading hours. Reports estimate the size of the intervention at JPY2.9–JPY3.6trn based on changes in current account balances at the BOJ. The actual amount will be revealed in the MOF's Foreign Exchange Intervention Operations report released on 30 September at 19:00 JST. Assuming the size of the intervention is in line with reports, it would have been the third largest in yen-denominated terms and the largest ever yen-buying operation (Table 1). However, given that the basic unit of foreign exchange transactions are denominated in dollars, the size of the intervention would come to USD20-25bn at an exchange rate of 145JPY/USD. Japan's largest currency intervention amounted to JPY8.6trn on 31 October 2011, which would come to about USD100bn based on the exchange rate at the time of around 75JPY/USD. The USD/JPY rate fluctuated by up to 3.8% on the day of the recent intervention, compared to about 5.6% on 31 October 2011. Despite the differences in the direction of the operations (yen-buying vs yen-selling), we would have to agree with Finance Minister Shunichi Suzuki's assessment that at least the initial impact of the intervention was effective. In addition, although the USD/JPY subsequently rebounded to just below 145, it has become top-heavy at this level. The USD has strengthened across the board as the turmoil in the bond market due to the UK's tax cut announcement has spread. Despite that, concerns that Japan could intervene again appear to have limited a rise in the USD/JPY. The MOF explained that the intervention was aimed at dealing with rapid market fluctuations (yen depreciation) and was not an attempt to intentionally shift toward a stronger yen. Based on this, we think it is fair to say that the intervention has had a sustained impact (although for less than a week at this point).

We note that when currency intervention involves selling the dollar and buying the yen, the market tends to focus on how much foreign currency is available as a source of funds. Foreign exchange reserves correspond to this, and Japan held USD1.3trn in reserves as of the end of August. Of this amount, about USD1.2trn is foreign currency. Securities accounted for USD1.0368trn and deposits USD136.1bn. Securities are mainly likely to be investments in USTs, but based on materials published in the past, securities with a remaining maturity of less than one year that should be easy to sell due to their high cash ability and liquidity are estimated to account for 14% of holdings. In other words, about USD168bn of securities and USD136.1bn of deposits (totaling about USD300bn) could be considered as funds that could be immediately tapped for interventions. Of course, we cannot be certain of how flexibly securities and cash could be used to finance currency interventions, but considering Japan spent USD25bn at most on 22 September, we think the government still has considerable buying power, although we would not call the war-chest massive. Many people had been skeptical that the government would actually intervene in the currency markets despite the rise in the USD/JPY and Japanese authorities becoming increasingly clear that they would move in response. This means the intervention has already probably had a strong psychological impact. The USD/JPY could rise past 145 again, but we think further catalysts will be needed for it to test the 1998 high of 147.64.

Hawkish shift in US monetary policy stance nearing its limit

We think the driving force behind the USD/JPY's sharp rise over the last six months has been the Fed's increasingly hawkish monetary policy stance, the accompanying rise in UST yields, especially in the intermediate sector, and the strengthening of the dollar. Yen depreciation due to the sense of divergence in monetary policy in Japan and abroad was fueled by the change in the Fed's stance.

The outlook for policy rates through 2025 presented at the September FOMC meeting was higher than the market had expected (Figure 3). Combined with the UK gilt shock that followed, this resulted in the 2y UST yield temporarily rising past 4.30% and the 10y yield above 4.00%. The outlook for the policy rate shown in the dot plot therefore seems to have been largely factored in. Meanwhile, regional Fed reports have pointed to signs of a slowdown in the US economy and inflation, and leading economic indicators are also trending downward. The labor market remains tight, but higher mortgage rates are softening real estate prices. It appears that the Fed's stance of curbing inflation even if it means dampening the economy has already been put into practice. In addition, the 75bp rate hike in September has pushed the federal funds rate well above the neutral rate of interest, meaning it has entered positive territory even in real terms (Figure 4) and that monetary conditions in the US will tighten in earnest from here. In other words, the slowdown in the US economy looks poised to move into full gear. The Fed has also accelerated the scaling back of its balance sheet since September. These conditions are putting downward pressure on stock prices, with the S&P500 falling to its lowest level since December 2020. However, the Fed looks prepared to accept a further slide in stock prices judging by its current stance.

As noted in last month's report, the Fed's stance of prioritizing efforts to curb inflation, even if this means hurting the economy and stock prices, has been supported by public dissatisfaction with rising prices. Gasoline prices have fallen slightly and supply constraints have been resolved to some extent, but we think the economic slowdown and decline in share prices could ramp up from here given the Fed's rate hikes and balance sheet cut backs point to a phase of fully-fledged monetary tightening. The key question is therefore whether the Fed can maintain its hawkish stance. In the run-up to the mid-term elections in November, the Fed is likely to face increasing pressure to be more mindful of the economy. At the very least, the environment which supported the Fed's increasingly hawkish stance has changed. The Fed is likely to be even more cautious in its dialogue with the market given Powell's comments after the July meeting raised expectations of an early interest rate cut. However, like it or not, the market will be highly focused on changes in the Fed's monetary policy from now through to the end of the year. We suspect that in retrospect the September FOMC meeting will mark the peak of the Fed's hawkish tilt. We also expect the dollar's strength is approaching an apex, although we are not yet certain what the specific trigger will be.

The dollar's strength versus other currencies has gained momentum since the UK gilt rout, but US authorities have been downbeat on taking measures to weaken the dollar. The strong dollar is already putting pressure on the profits of large global companies and traditional domestic manufacturers. Even so, the general consensus that the dollar should be allowed to rise in order to curb imported inflation is unlikely to change. Treasury Secretary Janet Yellen, who was expected to step down after the midterm elections, has also announced that she is willing to remain in office. It is therefore hard to imagine that the US will suddenly shift to an exchange rate policy that approves of a weaker dollar.

BOJ unlikely to act

Meanwhile, the BOJ in September made no major changes to its monetary policy, which has been a factor behind the yen's weakness. The Japanese authorities have adopted monetary policy settings which seek to weaken the yen domestically, while at the same time pursuing an exchange rate policy to defend its value externally through intervention in the foreign exchange markets. Governor Kuroda defended this as an appropriate policy mix when challenged that the policies of the government and BOJ were inconsistent and contradictory. In addition, at his press conference following the monetary policy meeting, he stated that changes to forward guidance and interest rate hikes (adjustment of the yield curve control policy) would not be necessary for "the time being." When asked how long that meant he went off script and answered that it should be assumed to mean a period of two to three years (this is published in the minutes of the press conference). Kuroda's remarks will not bind the policy decisions of the BOJ executive once he leaves office in April next year, but they suggest the Bank is unlikely to adjust its policy settings or change forward guidance at least while he remains at the helm. We therefore do not expect actions from the BOJ to narrow the divergence in monetary policy between Japan and overseas over the next six months.

Nominal interest rates are being held down by yield curve control measures and are unlikely to rise, while expected inflation rates should remain elevated. We therefore expect the real interest rate to remain low and see little prospect of a full-fledged shift to a stronger yen in the near term (Figure 5).

In light of this, the next BOJ Governor will probably be tasked with adjusting monetary policy, which currently seems to be aimed at sustaining existing policies themselves. The governor of the Bank is appointed by the Diet and the nomination is likely to be made at the regular Diet session in January. However, expectations of a change in monetary policy could come to the fore again if the name of a specific candidate is revealed. We expect the US to shift to a more accommodative monetary policy stance at this time, meaning that the divergence in monetary policy will narrow from both directions if the BOJ also moves to adjust its policy settings under the new leadership. In other words, the narrowing of the divergence in monetary policy in Japan and overseas could become the theme for next year or next fiscal year. The risk of a rapid decline in the USD/JPY could also emerge.

The Japanese government on 30 September announced that it had formulated a package of comprehensive economic measures. Apparently, the main pillars of the package will be a response to the sharp rise in prices and efforts to increase wages. The reason behind rising import prices has recently shifted from commodity prices to the weak yen (Figure 6). It is reasonable to assume that the rise in import prices due to the weak yen will be passed through to consumers despite any measures taken this time. We see the risk that this could increase public dissatisfaction as it has in the US, which could have an impact on monetary policy even before Kuroda's term expires.
