Secondary bond market

The municipal bond market is "doing pretty good for the moment," said Jeff Timlin, a managing partner at Sage Advisory.

The risk Brightline Florida poses to the rest of the high-yield market may manifest in fund flows, investors said.

Over the past three trading sessions, MMD yields have been bumped nine to 12 basis points, while UST yields have fallen over 20 basis points on the front of the curve.

Some bondholders have retained legal counsel while others are in the dark about the company's plans.

"If the narrative takes hold that the Fed is behind the eight ball and will need to cut rates several times in the coming months to catch up to the realities of a weaker economy, we expect muni yields will drift lower alongside treasuries," Birch Creek strategists said.

Municipal yields fell four to seven basis points, depending on the curve, while UST yields rallied nine to 30 basis points, with the largest gains on the front end.

Tax-exempt munis have underperformed year-to-date, said David Hammer, a managing director and portfolio manager at PIMCO.

The FOMC held rates steady at the conclusion of its meeting Wednesday and offered no hints regarding a September move.

The muni market has "cheapened and steepened," which is a great opportunity for people still on the sidelines to get into the market again, said Jennifer Johnston, director of municipal bonds research at Franklin Templeton.

The asset class got a "much-needed boost" from inflows into muni mutual funds last week, said Birch Creek strategists.

Issuance for the week of July 28 is estimated at $11.035 billion, with $9.018 billion of negotiated deals and $2.017 billion of competitive deals on tap, according to LSEG.

The top five featured in the ranking handled deals totalling more than $84 billion in par value.

Investors added $571.5 million from municipal bond mutual funds in the week ended Wednesday, following $224.6 million of outflows the prior week, according to LSEG Lipper data.

The fund's sell-off in June shows the challenges of accurate pricing in the high-yield muni market.

Larger dealer networks lead to lower markups, but smaller networks show evidence of potential collusion and market manipulation, the paper said.

Longer-term munis have become more attractive, said Cooper Howard, a fixed income strategist at Charles Schwab.

There is a buyer base that is a little bit "skeptical" of longer maturities, but it's more of a retail response, said Adam Congdon, a director at Payden & Rygel.

While the cost of small trades is higher than institutional trades across all fixed-income markets, the gap is more pronounced in the municipal bond market.

The primary market saw "decent subscriptions" last week, but the entire primary calendar came at "healthy concessions to where evals had been marked on existing bonds," Birch Creek strategists said.

First Southern LLC failed to timely and accurately report on trades executed for an affiliated hedge fund, FINRA said.
