Oil Tumbles 3.3%, Asian Currencies Rally as Trump Signals Iran Peace Breakthrough

Oil prices plunged and Asian currencies surged on Wednesday, May 6, 2026, after U.S. President Donald Trump announced he would pause the Project Freedom operation—a day-old military effort to escort ships through the Strait of Hormuz—citing "great progress" toward a "complete and final agreement" with Iran.

The abrupt shift in tone from the White House triggered a massive risk-on rally across global markets, with Brent crude tumbling 3.3% to $106 per barrel and oil-sensitive Asian currencies leading gains. The Korean won rose the most in nearly three weeks, while the Thai baht climbed as much as 0.8%—its biggest single-day increase since April 17.

Trump's Diplomatic Pivot Sends Oil Lower

Trump's announcement came via social media late Tuesday evening U.S. time, stating that Project Freedom would be paused "for a short period of time" based on requests from Pakistan and other mediating countries, as well as the "tremendous military success" and diplomatic momentum achieved so far.

The move marks an abrupt reversal from just days earlier, when Trump warned that the U.S. blockade of Iranian ports could last "months" and oil prices spiked to $126 per barrel—the highest level since 2022. That spike came after Iran escalated military actions in the Strait of Hormuz, hitting several vessels and setting a UAE oil port ablaze on Monday.

Brent crude (XBR/USD), which had jumped 6% earlier this week on those attacks, gave back those gains and more on Wednesday. West Texas Intermediate (WTI) crude fell 1.6% to $100.60 per barrel, retreating from recent multi-year highs.

The Strait of Hormuz, which carries roughly 20% of global oil supplies, has been effectively closed since late February when Iran seized control in response to U.S. military strikes. The closure triggered a global energy crisis, with oil prices more than doubling from pre-conflict levels around $80 per barrel.

Asian Currencies Rally on Risk-On Sentiment

Currency markets responded swiftly to the news, with oil-sensitive and risk-correlated Asian currencies posting their strongest gains in weeks.

The Korean won (KRW) led the rally, rising the most in almost three weeks against the U.S. dollar. The move was amplified by Samsung Electronics hitting a historic milestone: the South Korean tech giant's market capitalization crossed $1 trillion for the first time, driven by surging demand for AI microchips. Samsung shares jumped 14.8% in Seoul trading, pushing the Kospi index above 7,000 for the first time ever—a 6.6% single-day gain.

The Thai baht (THB) climbed 0.8%, its biggest increase since mid-April, as traders unwound bearish oil-shock positioning. Thailand, a net oil importer, stands to benefit significantly from lower crude prices and reduced cpi" title="Understanding inflation and CPI in forex">inflation pressures.

The Australian dollar (AUD/USD) also rallied, hitting a four-year high as the combination of easing oil prices and renewed risk appetite boosted the commodity-linked currency. Australia exports iron ore and coal to Asian manufacturing hubs, making the Aussie highly sensitive to regional growth sentiment.

The U.S. Dollar Index (DXY) weakened modestly as safe-haven demand ebbed, with market participants rotating back into risk assets and higher-yielding currencies.

Equity Markets Hit Record Highs

Global equity markets extended their rally, with multiple benchmarks hitting fresh all-time highs on the back of the Iran peace optimism and continued AI-sector momentum.

MSCI's All-Country World Index rose 0.4% to a new record, while its emerging markets benchmark and its broadest index of Asia-Pacific shares outside Japan jumped 2.8%—also setting new highs.

In Europe, the UK's FTSE 100 rose 1.7% in early trading, France's CAC 40 gained about 1%, and Germany's DAX climbed 1%. U.S. markets had already hit fresh records on Tuesday, with the S&P 500 up 0.8% and the Nasdaq Composite gaining 1%.

Bond Yields Ease, Gold Surges

The peace breakthrough also eased pressure on government bond markets, which had been selling off sharply on inflation fears tied to sustained high oil prices.

UK 30-year gilt yields—which hit their highest level since 1998 on Tuesday—dipped about 5 basis points to 5.68%. Lower oil prices reduce the risk of a prolonged inflation spike, which had forced central banks to signal potential rate hikes despite fragile economic growth.

Futures markets now expect about three 25-basis-point rate hikes by both the European Central Bank (ECB) and the Bank of England (BoE) over the next 12 months. The Federal Reserve is expected to remain on hold for the rest of 2026, with a 70% probability of a rate hike in 2027 if inflation remains elevated.

Meanwhile, gold (XAU/USD) surged nearly 2.5% to $4,667 per ounce, benefiting from both a weaker dollar and lingering geopolitical uncertainty. Despite the peace progress, analysts noted that the Strait of Hormuz remains effectively closed, and no formal agreement has been signed yet.

What Traders Should Watch Next

While Wednesday's rally reflects genuine optimism, analysts cautioned that the situation remains fluid and subject to rapid reversals.

"A dam of tension has eased with relief flooding into financial markets," said Susannah Streeter, chief investment strategist at Wealth Club. "But with the strait still effectively closed, government bond yields still remain well above their normal levels."

Mark Haefele, chief investment officer at UBS Wealth Management, noted Trump's comments marked an "abrupt shift" from recent days, but emphasized that sustained market relief depends on a formal peace agreement being finalized and signed.

Key levels to watch:

• Brent crude: Support at $100-105, resistance at $110-115. A break below $100 would signal confidence in a lasting peace deal.
• DXY: Watch for a sustained break below 103.50 if risk-on sentiment persists.
• AUD/USD: Four-year highs around 0.6850; next resistance at 0.6900.
• Gold: Support at $4,600; resistance at $4,700. Safe-haven demand may persist until a formal Iran deal is signed.

Traders should remain alert for any setbacks in the diplomatic process, renewed attacks in the Strait of Hormuz, or changes in Trump's tone. A collapse in peace talks could send oil prices surging back toward $120+ and trigger a sharp reversal in risk assets.

For now, markets are pricing in cautious optimism—but the rally's durability hinges on whether "great progress" translates into a signed, enforceable peace agreement in the coming days.
