The Overnight Rate

Since 2007

The 10-year closed at its highest since June 2007 while October hike odds fell to 42%. Junk-rated companies now borrow at about 8%. PCE prints at 8:30.

Every banker knows that if he has to prove that he is worthy of credit, however good may be his arguments, in fact his credit is gone.

Walter Bagehot, Lombard Street, 1873

Bagehot meant banks. This week the proving is being done by the lower-rated end of corporate America, and the price of the argument is about 8%.

Threshold: 8:30

BEA publishes August PCE, the inflation gauge the Fed targets, at 8:30, alongside the third estimate of second-quarter GDP and corporate profits (BEA schedule). July’s core PCE, excluding food and energy, rose 0.2% on the month and 3.3% on the year. Headline was 0.2% and 3.7% (BEA). Trading Economics has the August core consensus at 0.3% and 3.4% (Trading Economics).

Same line as Monday’s issue: a core monthly print at 0.4% or more, or 0.1% or less, is news. Anything in between probably leaves October near a coin flip. The second estimate had GDP growing at a 1.5% annual rate and profits up $400.9 billion (BEA).

Who pays: the junk-rated borrower

ICE BofA’s high-yield index, the bonds of companies rated below investment grade, yielded 8.03% on Monday, from 7.46% a week earlier. Its spread over Treasuries went from 2.73 percentage points last Wednesday to 3.02 (FRED). Investment-grade companies yield 5.97%, and their spread barely moved, 0.77 to 0.83 (FRED). Strong borrowers are paying for higher Treasury yields; weaker ones pay a doubt premium on top.

The mechanism, once: a company refinancing a maturing bond pays the new yield on the whole amount for the life of the new bond. At last week’s 7.46%, a $100 million issue costs $7.46 million a year in interest. At Monday’s 8.03% it’s $8.03 million, $570,000 more, every year until it matures.

Payer: the lower-rated company with a bond coming due now. Payee: the bond buyer who waited a week. The yield only bites when the old bond rolls, so I’d argue the maturity calendar matters more here than a week of stock prices.

Net net: a junk-rated company that refinances this week pays about 0.6 points a year more than one that refinanced last week, and it keeps paying.
