Why the Dollar and Asian Currencies Keep Bouncing Around

The dollar has been stuck in a holding pattern. The WSJ Dollar Index sat at 97.20 on July 10, 2026, having drifted down from 97.28 the day before and 97.64 just over two weeks earlier on June 25 The Wall Street Journal. Asian currencies have been range-bound — stuck between roughly the same levels — for three weeks now. But something underneath that apparent calm has shifted. The reasons pushing the dollar around have changed from one week to the next: Federal Reserve policy, then Middle East tensions, then back to investor appetite for riskier bets.

What's been moving the markets

For weeks in mid-June, the focus was the Fed. On June 17, the WSJ reported that Treasury bond yields and the dollar were rising together, an unusual pairing that typically means investors expect the Fed to raise rates sooner or stay higher for longer — not that they were fleeing to safety The Wall Street Journal. By June 25, that narrative held firm. The Dollar Index had climbed to 97.64, and the WSJ attributed the strength to expectations of Fed rate hikes The Wall Street Journal.

Then the Middle East escalated. On July 13, Reuters reported the dollar jumped on renewed U.S.-Iran attacks and fears of a Strait of Hormuz closure, with the yen weakening to 162.43 per dollar, up 0.46% on the day Reuters. That move stands out against the backdrop of a Reuters report from July 1 showing the yen had already fallen to a 40-year low earlier that week, with dollar traders gaining confidence even as most currency strategists still expected the dollar to weaken eventually Reuters. When a geopolitical shock hits, it can temporarily override the longer-term logic that normally guides currency trades.

The details matter

On July 6, the Dollar Index eased to 97.26, and the WSJ described the move as possible position adjustments — essentially traders rebalancing their bets at month-end or quarter-end The Wall Street Journal. The Indian rupee closed that day at 95.3950 per dollar, down 0.2%, with weak regional peers and downward momentum rather than any Indian-specific news driving the move, according to Reuters Reuters. Three days later, on July 9, the WSJ flagged Middle East tensions explicitly as the weight on regional currencies The Wall Street Journal.

Why energy-importing countries are vulnerable

The channel running from oil prices to Asian currencies isn't new. Back on May 21, Reuters reported that Asian currencies were already flashing warning signs of an oil shock, with the Indonesian rupiah at 17,700 per dollar and the Indian rupee approaching 97 Reuters. Here's the mechanical reason: countries that import a lot of oil, like India and Indonesia, see their trade deficits widen when oil prices spike. That happens at the exact moment when global risk-aversion is already pushing foreign investors to pull money out of Asian markets and move it back home. Both forces hit at once. The rupee's bounce back toward 95.40 from near 97 suggests that initial panic had eased before the latest Middle East tensions brought the same risk back into focus.

The bigger picture

The International Bank for Settlements flagged growing unease in FX markets back in March 2026, describing conditions as already tilted toward risk-off — a technical term meaning investors were pulling back from riskier bets BIS. MUFG Research, writing later that month, said Asian currency weakness was deepening, with both geopolitics and interest-rate differences working together to support the dollar MUFG Research. The pattern since then has been relief followed by relapse: the dollar softens on position adjustments or when investors feel brave enough to take risks again, then geopolitical or monetary-policy shocks push it back up.

For traders managing Asian currency portfolios, the key distinction is simple: Is the dollar genuinely in a new era, or is it just bouncing around within a range? Over the past month, nothing has pushed the index decisively outside the 97.20–97.64 band. What has shifted is why the dollar sits where it does — first Fed policy uncertainty, then Middle East conflict, now a tentative rebound in risk appetite. The rupee and rupiah both moved toward weaker levels (97 and 17,700 respectively) earlier this year, and those moves show how much damage a real Strait of Hormuz closure could inflict on energy-importing countries. The market has already priced in some version of that scenario once this year. Whether it happens again is a different question.
