Investors just poured $2.76 billion into high-yield bond retail funds in a single stretch, driven overwhelmingly by ETF activity and a market mood that’s grown considerably sunnier since the Iran peace bid surfaced in May 2026.

The move is part of a much larger migration into fixed income. Bond ETFs collectively attracted over $300 billion in inflows during the first half of 2026.

Why high-yield bonds are suddenly everyone’s favorite trade

US high-yield corporate bonds are offering yields between 5.75% and 12.7% as of June 30, 2026, depending on credit rating. Credit quality across the high-yield segment has been improving, with default rates trending lower than in previous cycles.

The Iran peace bid, which gained traction in May 2026, has meaningfully reduced the risk premiums that had been baked into markets.
