Finance minister “calls out” the 1.8 trillion GPIF, triggering a sharp yen surge; Goldman Sachs douses the flames: but it’s just “an overreaction”

Japan’s Finance Minister Satsuki Katayama on Friday used a routine press conference to explicitly call on pension institutions—including GPIF, one of the world’s largest pension funds—to increase their investment in Japan’s domestic financial assets. The remarks, apparently prepared in advance, caught the market off guard: the yen surged against the US dollar in the short term to 161.29, and Japan’s government bond yield curve moved down overall by about 10 basis points.

Katayama’s comments were apparently prepared in advance. According to Bloomberg, citing people familiar with the matter, her remarks about GPIF had been drafted ahead of time. It is still not possible to confirm whether this statement amounts to a kind of indirect verbal intervention, but in terms of immediate impact, its effect on the yen’s exchange rate has been stronger than Japan’s central bank’s recent rate hikes and its ongoing verbal guidance.

GPIF manages assets worth as much as 293.6 trillion yen (about $1.81 trillion), with roughly half allocated overseas. Any real shift toward increasing domestic holdings would mean selling foreign currency and buying yen, directly boosting yen demand at the trading level. However, the cool analysis coming from major Wall Street banks is rapidly cooling the market’s optimism.

A pre-prepared “call-out”

Katayama’s remarks were made in response to a reporter’s question about the government’s investment plan. She said: “The top priority is to encourage households and pension funds, including GPIF, to increase investment in Japan’s financial assets. We plan to roll out policies that support this goal.”

The background to the speech is that Japanese Prime Minister Sanao Takashi announced an economic investment plan last month lasting 14 years with a total value of 370 trillion yen, with more than one quarter earmarked for artificial intelligence and the chip sector. Katayama emphasized that the government wants to “ensure that the public can directly benefit from Japan’s economic growth.”

It is also worth noting that the Takashi administration is known for supporting an accommodative monetary policy. An early draft of its economic policy platform initially prompted market concerns that the government was trying to influence the Bank of Japan’s independence, and it was later revised multiple times to allay worries. On Friday, Katayama also made clear that monetary policy should be handled independently by the Bank of Japan.

After the yen’s surge: Goldman Sachs and State Street raise questions about persistence

After Katayama’s remarks, the yen rose at one point to 161.29, before giving back part of the gains. Japan government bonds rebounded across the board, with yields down by 5 to 11.5 basis points above the middle of the curve.

However, in a report to clients, Goldman Sachs said bluntly that this bond-market rebound was an “overreaction.” The bank noted that the finance minister used the broad phrase “Japanese financial assets” and did not clearly commit to GPIF making a large-scale increase in holdings of Japanese government bonds. Goldman maintained its structurally bearish view on ultra-long-dated Japanese government bonds, arguing that the rebound does not represent a trend reversal.

On the FX front, Goldman analyst Karen Reichgott Fishman wrote that these comments “do not mean an actual shift in government policy.” Over the past year, investors’ expectations for Japan’s capital to flow back have repeatedly been raised (such as after an early election), but they have never materialized.

“We have long been skeptical about a significant yen-positive capital inflow emerging without a more favorable interest-rate spread environment—especially since GPIF still has return targets to meet.” Still, it also acknowledged that any meaningful inflow would be “one of the more credible paths,” given the yen’s severe undervaluation needing correction.

Kazushige Kaida, head of FX sales at State Street’s Tokyo branch, echoed a similarly cool stance: “The macroeconomic backdrop hasn’t changed, so it’s hard to see the yen strengthening over the long term. If the latest statement is simply indicating that the government is seeking to ease the pains of its re-inflation policies rather than abandoning those policies, then the big narrative of yen weakness will remain unchanged.”

GPIF: a giant ship adjusted every five years; a shift in the near term is unlikely

GPIF is regulated by the Ministry of Health, Labour and Welfare, not the Ministry of Finance. Its asset allocation parameters are adjusted once every five years. In March 2025, the fund decided to maintain the existing framework: domestic equities, domestic bonds, foreign equities, and foreign bonds each at 25%, and it narrowed the maximum allowable deviation for each asset class from the previous 6–8 percentage points to 5–6 percentage points.

Japan’s four public pension funds combined manage about 332 trillion yen in assets, led by GPIF. In the fiscal year ended March 31, GPIF recorded the third-highest annual return in history.

Yugo Tsuboi, chief strategist at Daiwa Securities, said that given GPIF’s massive asset-management scale, potential changes in allocation are “not to be ignored.” Katayama’s remarks “may help sustain the ‘triple up’ setup across Japan’s bond market, the yen, and stocks.”

Yukihiro Kawanishi, a senior strategist at Aizawa Securities, believed that a shift toward Japanese financial assets would be beneficial for Japan’s stock market and could also encourage overseas investors who have already positioned themselves in advance to add to their holdings.

However, from the standpoint of institutional procedures, any changes to GPIF’s investment strategy must go through established processes and take a long time to implement. Between the Ministry of Finance’s “call-out” and actual changes in asset allocation lies an entire set of institutional arrangements that take time—exactly the reality Goldman Sachs and State Street are betting on.
