BoJ's Himono Testimony Looms as Yen Hits 38-Year Low

Bank of Japan Deputy Governor Shinichi Himono is scheduled to speak before Japan's parliament at 0000 GMT on June 22, 2026. The testimony comes with the Japanese yen trading at a 38-year low against the US dollar, a level that prompted fresh verbal intervention from Finance Minister Katayama. According to reporting by investinglive.com, Minister Katayama reiterated that authorities stand "ready to respond as needed" to excessive currency moves. The USD/JPY pair breached the critical 165.00 level in Asian trading, intensifying focus on the central bank's policy stance.

Context — Why this matters now

The USD/JPY exchange rate breaking above 165.00 marks its weakest point for the yen since the Plaza Accord era of December 1986. This depreciation persists despite the Bank of Japan's first interest rate hike in 17 years, enacted in March 2026. The widening interest rate differential with the United States remains the primary catalyst; the Federal Funds Rate sits at a 5.25-5.50% target, while the BoJ's policy rate remains below 0.50%. This gap creates a powerful incentive for capital to flow out of yen-denominated assets into higher-yielding US Treasury bonds, a dynamic known as the carry trade. The Ministry of Finance's verbal interventions have so far failed to alter this fundamental driver, increasing pressure on the BoJ to signal a more aggressive tightening path.

Data — What the numbers show

The yen has depreciated over 14% against the US dollar year-to-date, significantly underperforming other G10 currencies. The USD/JPY pair has moved from a 2026 opening level near 145.00 to a current high of 165.50. For comparison, the Euro is down approximately 4% against the dollar over the same period. Japanese government bond (JGB) yields have risen but remain low by global standards; the 10-year JGB yield trades around 1.10%, compared to the US 10-year Treasury yield of 4.35%. The scale of the move is evident in key support levels that have been breached.

Level	Significance	Status
160.00	Previous multi-decade high (Oct 2025)	Breached
165.00	Psychological Threshold	Breached
170.00	Next major psychological level	Uncharted Territory

Japan's core inflation has held above the BoJ's 2% target for over two years, with the latest print at 2.3%.

Analysis — What it means for markets / sectors / tickers

A weaker yen creates clear winners and losers within Japanese equities. Major exporters like Toyota Motor (7203.T) and Sony Group (6758.T) benefit significantly, as their overseas revenues are worth more when converted back to yen. Conversely, Japanese importers and utilities like Tokyo Electric Power (9501.T) face severe margin pressure from higher costs for dollar-denominated energy and raw materials. The currency's decline also pressures regional peers; the Korean won and Chinese yuan face competitive devaluation risks, which could negatively impact exporters like Samsung (005930.KS). A key risk to this analysis is that prolonged weakness could trigger an abrupt, disorderly reversal if the BoJ is forced into direct FX intervention, potentially causing a sharp snapback in the yen. Institutional flow data shows leveraged funds maintaining large short yen positions, betting on further depreciation.

Outlook — What to watch next

Immediate focus is on the tone of Deputy Governor Himono's testimony; any deviation from the BoJ's cautious communication will be scrutinized for hints of accelerated policy normalization. The next major data catalyst is the Tokyo Consumer Price Index release on June 27, a leading indicator for national inflation trends. The Bank of Japan's next policy meeting is scheduled for July 16-17, where pressure for another rate hike may intensify if yen weakness persists. Traders will monitor the 166.00 level as the next potential resistance for USD/JPY, with the 170.00 handle acting as a longer-term target if intervention fails to materialize. The 160.00 level is now viewed as a key support level following its breach.

Frequently Asked Questions

What does a weak yen mean for the Japanese economy?

A weak yen provides a short-term boost to large exporting corporations by making their goods cheaper overseas and increasing the yen-value of foreign profits. However, it significantly increases the cost of living for Japanese households by raising prices for imported food, energy, and consumer goods. This creates a bifurcated economy where corporate earnings may rise while real wages and consumer spending power decline.

Has the Bank of Japan intervened in the forex market recently?

The last confirmed direct intervention by the Japanese Ministry of Finance to support the yen occurred in October 2025, when USD/JPY was trading near the 160.00 level. The intervention, which involved selling US dollars and buying yen, was estimated to be over $60 billion. The effectiveness of such interventions is often temporary unless accompanied by a shift in fundamental monetary policy.

How do carry trades impact the yen's value?

In a carry trade, investors borrow Japanese yen at near-zero interest rates and sell the currency to buy higher-yielding assets like US Treasury bonds. This mass selling of yen to fund purchases of other currencies creates persistent downward pressure on the JPY. The trade remains profitable as long as the yen's depreciation and the interest rate differential outweigh the transaction costs.

Bottom Line

The yen's plunge to a 38-year low tests the BoJ's commitment to gradual policy normalization amid intense market pressure.
