The U.S. dollar fell on Friday, August 21, poised to close the week lower as investors grew concerned that the U.S. Treasury’s efforts to calm bond markets could signal weak conviction in the greenback.
Today, the U.S. Dollar Index (DXY), which measures the U.S. currency against a basket of six of its peers, dropped roughly 0.25% to 98.64 which is its lowest level in the last three months.
The currency sell-off escalated after Treasury Secretary Scott Bessent announced a sudden policy shift to double the department’s liquidity-support buybacks of long-term government debt from $2 billion to $4 billion per operation, which could be ramped up further if necessary.
Financial Repression vs. Currency Value
The Treasury’s aggressive tactic initially aimed to provide relief to a battered fixed-income market after the 30-year Treasury yield hit a 19-year high of 5.31%. However, the relief proved short-lived; yields quickly rebounded back toward 5.26% as fading market confidence and deep fiscal deficits overrode the government’s intervention.
Consequently, capping yields to suppress mounting government borrowing costs has stripped the dollar of its critical interest-rate advantage. Jonas Goltermann, Chief Markets Economist at Capital Economics, warned that a “hint of financial repression” and “more unconventional policy is unhelpful, concerning the dollar. He also added that our coming months’ forecast signals a weak conviction for dollar rebound, according to a report from Reuters.
Deficit Fears Outweigh Safe-Haven Bids
The currency’s devaluation takes place amid an uncertain geopolitical environment. The risk of continuing conflict in the Middle East keeps global energy prices high and further obscures the medium-term inflation forecast.
Geopolitical supply shocks usually trigger safe-haven inflows into the dollar, but investors are less inclined to buy because of the high fiscal deficits and the long-term sustainability of U.S. national debt.
High-Stakes Setup for Jackson Hole
The Treasury’s market intervention sets up a tense environment for the Federal Reserve’s upcoming Jackson Hole symposium. Investors are awaiting for a key address from Fed Chair Kevin Warsh.
Economists caution that the Treasury’s liquidity measures could stoke persistent inflation, potentially forcing the Fed to prolong its hawkish monetary stance. Consequently, Chair Kevin Warsh’s upcoming address will be heavily scrutinized for any indications of how the central bank plans to safeguard its inflation-fighting credibility amid intensifying friction between fiscal intervention and monetary policy.
Yen Gains After Japan’s Core Inflation Accelerates
The Japanese yen gained 0.18% to 158.74 against the U.S. dollar on Friday after July data showed accelerating core consumer inflation, bolstering expectations for a Bank of Japan (BOJ) interest rate hike.
“The yen is certainly salvageable, but it’s not a one-way train,” said Roosevelt Bowman, senior investment strategist at Bernstein Private Wealth. “If the BOJ policy were seen as more symmetric—with the central bank pushing against any inflationary pressures—it would help the yen.”
While last month’s joint intervention by U.S. and Japanese authorities halted the currency’s slide, analysts stress that intervention alone cannot sustain long-term strength without monetary tightening.
Markets are now focused on the BOJ’s next policy meeting on September 17–18 for signals on further rate hikes.
USD/JPY Wobbles In a Narrow Range Before Next Breakout
Over the past two weeks, the USD/JPY pair has been wavering between the 100-and-200-day exponential moving averages (EMAs), marking a range from 157.7 to 159.72. The sideways action reflects broader market uncertainty amid geopolitical tension and U.S and Japan’s monetary policy.
The momentum indicator RSI at 42 highlights the current bearish momentum in this pair, signaling a potential challenge to the 200-day EMA. If the Japanese yen continues to hold its strength against the dollar, the currency pair could break below the 157.7 floor and extend its correction to 155.2.

Conversely, if the U.S. dollar manages to rebound and push the USD/JPY exchange rate above the 159.72 barrier, the pair could surge to the 161.23 ceiling.
