Global stock markets mostly rose on Wednesday and the dollar fell sharply after the US Treasury signaled action to push down government bond yields. This move eased fears that higher borrowing costs would weigh on economic growth worldwide. The announcement came as a surprise to markets, providing relief to equities that had been under pressure from rising sovereign yields.

## US Treasury's Move to Lower Yields

The US Treasury announced it would increase its sovereign bond buybacks by at least double to push down 30-year yields that had soared in recent days. This move was seen as a strong signal that the Treasury deemed higher US yields unacceptable. The shift in bond yields provided relief for equities, particularly tech companies that are heavily borrowing to fund AI investments.

## Market Reactions and Economic Context

After three straight losing sessions, Wall Street indices advanced, though the gains were modest. The S&P 500 ended up 0.2 percent. Oil prices continued to rise amid doubts about reopening the Strait of Hormuz to tanker traffic, exacerbating inflation fears that have rattled markets since the US-Iran war began nearly six months ago.

Minutes from the Federal Reserve's last meeting revealed that many policymakers believe interest rate hikes will be necessary if inflation does not decline. The meeting noted that economic activity had continued to expand at a solid pace, with business investment concentrated in AI industry expenditures.

## Geopolitical Tensions and Market Impact

Geopolitical tensions in the Middle East continued to influence market sentiments. US President Donald Trump's decision not to extend a 60-day truce with Iran dimmed prospects for a Middle East deal. The Strait of Hormuz remains a flashpoint, with Washington's naval blockade on Iran's ports and Tehran's attacks on commercial ships continuing. Iran's armed forces warned Gulf countries against assisting the US military, following the United Arab Emirates' decision to sever economic ties with Tehran.
