Highlights
- 57% of surveyed economists now expect a Bank of Japan rate hike in September, up sharply from 5% in the prior survey.
- A narrow majority forecast rates reaching at least 1.50% by Q1 2027, the highest since the 1990s.
- 89% of economists say PM Takaichi's fiscal stance supports a faster pace of tightening.
- The shift matters for crypto because a hawkish BOJ threatens the yen carry trade that has funded risk-asset positioning.
A new economist survey shows a dramatic shift in expectations for Japanese monetary policy: 57% of respondents now expect the Bank of Japan to hike interest rates in September, up from just 5% in the prior poll, according to Coin Bureau. A narrow majority of those surveyed also forecast rates climbing to at least 1.50% by the first quarter of 2027, which would be the highest level in Japan since the 1990s. Separately, 89% of economists said Prime Minister Sanae Takaichi's fiscal stance is now supportive of faster BOJ tightening rather than an obstacle to it.
That marks a reversal from earlier in the year, when a Bloomberg survey found half of economists expected the BOJ to wait until December for its next move. Reporting from MUFG Research now projects the BOJ raising its policy rate to 1.25% as soon as September, with Governor Kazuo Ueda reportedly getting support for a hike from multiple directions — including, notably, from a Takaichi government that had been expected to resist tighter policy given its growth-focused agenda.
Why the Consensus Flipped So Fast
The swing from 5% to 57% in a single survey cycle is unusually large for a G7 central bank forecast. It reflects two forces converging: persistent inflation pressure in Japan that has outlasted BOJ officials' earlier “transitory” framing, and a political environment that has stopped fighting the central bank's tightening bias. Takaichi's government backing a hike removes what had been the single biggest source of uncertainty around BOJ timing, since a Japanese prime minister publicly at odds with the central bank has historically been enough to delay action by a full quarter or more.

The Crypto Angle: Carry Trade Risk
A BOJ that moves faster than expected has direct implications for crypto markets through the yen carry trade, where investors borrow cheaply in yen to fund purchases of higher-yielding assets abroad, including equities and, increasingly, digital assets. Rapid unwinds of that trade have historically coincided with sharp, correlated sell-offs across risk assets — a dynamic markets saw play out in past BOJ tightening surprises. With rates potentially reaching 1.50% by Q1 2027 rather than staying pinned near zero, funding costs for yen-based leverage rise meaningfully, and that pressure tends to show up first in the most liquid, most leveraged corners of crypto markets. It's a similar dynamic to how the PBOC's easing moves ripple into global liquidity conditions, just running in the opposite direction.
What to Watch Next
The next concrete checkpoint is the BOJ's September policy meeting, with some analysts now flagging September 18 specifically as a plausible hike date. Between now and then, yen volatility and any further comments from Takaichi's cabinet will be the clearest signals of whether this survey shift holds. A confirmed hike would also make the BOJ the first major central bank moving decisively toward tighter policy while the Fed weighs its own path, a divergence that crypto traders are already watching closely heading into the back half of the year.
