Vietnamese Dong Weakens as Dollar Holds Near One-Month High

Currency Movements in Hanoi

The Vietnamese dong weakened against the U.S. dollar on Wednesday morning, reflecting broader pressure on Asian currencies as the greenback maintained strength ahead of a pivotal Federal Reserve policy decision.

Vietcombank sold the dollar at VND26,530, representing a 0.02% increase from the previous day's close, according to the bank. In parallel markets, the currency depreciated 0.08% to approximately VND26,380.

The State Bank of Vietnam held its reference rate steady at VND25,293, a record high for the official benchmark. The central bank's decision to maintain the rate signals continued vigilance as external pressures mount on the dong.

Regional Currency Pressure

Vietnam's exchange rate movements come as the dollar traded at 101.38 against a basket of major currencies Wednesday, hovering near a one-month peak. Geopolitical tensions in the Middle East have bolstered demand for safe-haven assets, supporting dollar strength across emerging markets.

The dollar reached a 40-year high against the Japanese yen at 163.74, while the euro inched up just 0.03% to $1.1389 after touching a one-month low in the previous session. The Australian dollar fell 0.37% to $0.69475, and sterling eased 0.03% to $1.3287, near its weakest level since early July.

For Vietnam, the dong's slide reflects the broader challenge facing Asian central banks as they navigate dollar strength driven by U.S. monetary policy expectations. The country's export-dependent economy remains sensitive to currency fluctuations that affect trade competitiveness.

Fed Decision in Focus

Market participants across Asia are awaiting the Federal Reserve's interest rate announcement later Wednesday, with the policy decision expected to shape currency trajectories in the coming weeks.

OCBC strategist Sim Moh Siong noted that the Fed appears to be shifting in a more cautious direction regarding rate cuts. While no rate increase is anticipated at this meeting, the central bank's forward guidance will likely determine whether dollar strength persists.

"If the Fed stays on hold and provides a bit of a hawkish guidance, then I think the dollar is likely to stay supported," Sim said.

A hawkish Fed stance could extend pressure on the dong and other regional currencies, particularly if U.S. rate expectations diverge from easing cycles elsewhere in Asia. Vietnam's central bank has limited room to maneuver given inflation concerns and the need to maintain export competitiveness.

Vietnam's Currency Management

The State Bank of Vietnam has kept its reference rate at elevated levels in recent months, balancing the need to prevent excessive dong depreciation against the risk of tightening financial conditions too aggressively. The gap between the official rate and commercial bank rates reflects ongoing market pressure.

Vietnam's foreign exchange reserves and monetary policy toolkit will be tested if dollar strength persists through the remainder of 2026. The central bank has historically intervened in currency markets to smooth volatility, though sustained one-way pressure can strain reserves.

The dong's performance matters not only for inflation management but also for the confidence of foreign investors in Vietnamese equities and bonds. A stable currency environment supports capital inflows into the country's growing financial markets and manufacturing sector.

Wednesday's currency movements underscore the interconnected nature of Asian financial markets with U.S. monetary policy. As the Fed navigates its own inflation and growth challenges, the ripple effects continue to shape exchange rate dynamics from Hanoi to Jakarta.
