Global Markets React to Hawkish Fed, Yen at 40-Year Low, and Plunging Oil Prices

At Warsh's first meeting as Fed chair in June, the FOMC voted 12-0 to leave the federal funds rate unchanged in a range of 3.50%–3.75% . The committee also launched a sweeping review of monetary policy frameworks, including new task forces on inflation, communications, and AI .

Market impact: The dollar held steady near 13-month highs as markets repriced expectations for a longer hold on rates . US Treasury yields rose under pressure from the hawkish Fed stance . Inflation measured by the personal consumption expenditures price index is projected at 3.6% for 2026, well above the 2% target .

Yen Plunges Past 162 to a 40-Year Low — Intervention Clock Ticking

The Japanese yen weakened beyond 162 per dollar, hitting a fresh 40-year low of 162.84 overnight on July 1–2 . This is the weakest level for the yen against the dollar since 1986 . The slide has been relentless: the yen traded near 160.80 in mid-June, slipped to 161.81 on June 19, breached 162 on June 30, and kept falling .

Traders are on high alert for intervention by Japanese authorities, with thin trading ahead of the US July Fourth holiday seen as a potential window for Tokyo to step in . Japan's Ministry of Finance has previously intervened to support the currency, but those efforts failed to halt its slide . The yen has weakened roughly 13% against the dollar over the past 12 months .

Oil Falls to 4-Month Lows on US-Iran Talks Progress

Oil prices fell more than 1% on July 1 to their lowest since March, with Brent crude settling at $71.57 per barrel (down 1.89%) and West Texas Intermediate at $68.58 . President Trump said US-Iran talks in Qatar "are going well," easing supply disruption fears .

The decline has been building for weeks. Brent crude dropped roughly 21% in June alone — its largest monthly decline since March 2020 . A US-Iran interim peace deal signed in mid-June reopened the Strait of Hormuz and signaled potential sanctions relief, allowing more Iranian oil exports . The US granted a 60-day waiver permitting certain exports of crude and fuel from Iran, referencing "constructive discussions" in Switzerland .

However, the outlook remains uncertain. Weekend missile exchanges between the parties have kept the situation fragile, and mixed diplomatic signals from Tehran have prevented a complete sell-off . Brent crude remained near $71 per barrel as of July 2, with the market pricing in a supply recovery but sensitive to any reversal in talks .

Asian Equities: Cautious Start to Q3

Asian share markets began the new quarter in a cautious mood on July 1. US-Iran talks hit new hurdles, and the yen's slide unnerved investors . Bond markets were also under pressure as US Treasury yields spiked .

Earlier in June, Asian tech stocks had taken a significant hit from a Wall Street AI rout. South Korea's KOSPI fell 8.3%, and Japan's Nikkei dropped 3.9% as the AI surge lost momentum . The 2-year Treasury yield surged to its highest level in 16 months during that period .

Emerging-Market Currencies and Bonds: A Mixed Picture

Foreign investors are piling back into Asian emerging-market bonds despite renewed Fed hawkishness, betting that regional central banks will keep rates elevated, making the debt attractive . Emerging Asian bonds are showing relatively less sensitivity to moves in Treasuries: the 30-day correlation between 5-year US yields and similar-dated emerging Asia yields is around 0.04, versus 0.34 for EMEA and 0.44 for Latin America .

Meanwhile, the strong dollar and rising US yields are keeping pressure on emerging-market currencies broadly, with the dollar index holding firm . The yen has been one of the biggest casualties of dollar strength .

Key Bottom Line

Markets are pricing a "higher for longer" Fed, a yen that may trigger Bank of Japan intervention at any moment, and oil that has already discounted a diplomatic breakthrough with Iran — but remains highly sensitive to any reversal in talks. Emerging Asian bonds are the one pocket of resilience, drawing foreign inflows on yield appeal despite the hawkish global backdrop.
