Japan’s move to defend the yen is adding new pressure on the U.S. dollar while the Federal Reserve weighs whether to cut interest rates or keep them higher for longer.
Roger J. Kerr, executive chairman of Barrington Treasury Services, framed the Fed’s dilemma in his latest commentary for interest.co.nz as global oil pressure, currency volatility, and mixed U.S. economic signals collide.
“If they do not cut interest rates they could send the US economy into recession,” Kerr wrote.
But cutting rates carries its own risk.
“If they cut interest rates and resultant stronger economic activity keeps inflation well above 2,00%, they are outside their mandate,” Kerr wrote.
“The waiting game continues for the Fed,” Kerr added.
Fed Vote Shows Division
The Federal Reserve left interest rates unchanged at its April 29 meeting and kept language in its statement pointing toward possible future rate cuts, according to Kerr.
Three voting members dissented from keeping that forward guidance: Lorie Logan, Beth Hammack, and Neel Kashkari. Kerr described all three as Fed “hawks” who have warned about rising inflation and the need for tighter monetary policy.
Eight members voted to keep the easing bias, while Stephen Miran voted for rate cuts.
Fed Chairman Jerome Powell said after the April 29 meeting that higher energy prices would push up overall inflation in the near term, while the longer-term economic effects remain unclear.
Japan Moves To Defend Yen
The Fed’s dilemma comes as Japan moves to stop the yen from weakening beyond 160 to the U.S. dollar.
Japanese Finance Minister Satsuki Katayama warned markets last week that Japan was prepared to act against excessive yen volatility.
The Bank of Japan then bought yen and sold U.S. dollars, marking Japan’s first direct currency intervention in nearly two years, according to Kerr.
The yen strengthened from 160.70 to 155.50 against the dollar on April 30, its largest single-day move since December 2022. The yen later gave back some gains and closed the week near 157.00.
Kerr said Japan timed the move before Golden Week public holidays, when thinner trading can make intervention more powerful.
Bond Gap Matters For U.S. Dollar
Currency intervention alone may not push the dollar-yen exchange rate much lower unless the Bank of Japan also raises interest rates, Kerr argued.
Current estimates show the Bank of Japan preparing to lift its official interest rate from 0.75% to 1.00% in June.
Japan’s 10-year government bond yield has climbed to 2.50%, its highest level since February 1999, while the U.S. 10-year Treasury yield sits at 4.37%, according to Kerr.
That shrinking gap could matter for the United States. Japanese investment firms may move money out of U.S. bonds and back to Japan if the interest-rate advantage no longer justifies the currency risk.
That kind of shift would require investors to buy yen and sell U.S. dollars.
U.S. Economy Sends Mixed Signals
Kerr said the U.S. economy is sending conflicting signals in early 2026.
Core CPI and PCE inflation readings have largely matched forecasts over the first three months of the year. Tariff-related price increases from a year ago have started rolling out of annual inflation data, while shelter costs continue to decline.
Those trends could still leave the Fed room to cut rates this year if the Iranian war ends soon and oil prices fall.
The labor market is harder to read. The Trump administration’s immigration policies have reduced labor supply, while reduced demand has helped keep unemployment stable, according to Kerr.
At the same time, AI-related layoffs have hit software and technology companies. Hiring intentions in the recent ISM Manufacturing survey fell to 46.4, below forecasts of 49.0.
Annualized U.S. GDP growth of 2.00% in the March quarter came in slightly below forecasts. Business investment in data centers tied to AI dominated the GDP figures, while consumer spending grew at a slower 1.60% pace.
Kerr also cited a TransUnion report showing a more divided economy, with higher-income households benefiting from stronger investment portfolios while lower-income households face higher costs and rising debt burdens.
Housing is another pressure point. The 30-year Treasury yield has climbed to 5.00%, pushing fixed rates for new-build mortgages above 7.00%.
Dollar Faces New Test
For U.S. investors, Japan’s yen defense is not just a foreign currency story. It adds another test for the dollar, the bond market, and a Federal Reserve trying to avoid a policy mistake.
Kerr’s analysis leaves a central question for markets: whether the Fed can hold inflation in check without turning rate policy into a recession trigger.
