When the Pipes Diverge, Who Moves?
The Federal Reserve’s switching evidence asks a precise question: when a middle-market firm takes a new loan, has its financing source changed from private credit to leveraged loans or in the other direction? This chapter explains what that observation counts, how relative market conditions trigger movement, and why a high switching share among eligible firms cannot be read as a universal escape route for PC-dependent borrowers.
The distinction matters because “switching” sounds like a simple transfer between two accounts. In the data, it is a change in financing source across consecutive loans, observed only when a firm takes another loan. The direction, timing and denominator determine what the percentage tells us.
What the switching measure counts
At each quarter, the Federal Reserve looks at firms with a new loan in the trailing twelve months. An LL-to-PC switch occurs when a firm’s prior loan was in the leveraged-loan market and its current loan is in private credit. A PC-to-LL switch is the reverse. The measure therefore follows a borrower through a sequence of financing events rather than comparing the total stock of PC and LL debt.
That design has two useful features. First, it captures a choice made when a firm actually needs new financing, not merely the possibility that two markets serve similar industries. Second, it allows the direction of movement to be compared with relative market conditions. If leveraged-loan investors demand a higher excess premium, the LL market is considered tighter in the Federal Reserve’s analysis. A firm that already has a route into PC may then use it for the next loan.
The design also imposes important limits. A firm with no new loan during the observation window does not appear as a switcher, even if its refinancing options have narrowed. A firm that is denied credit in both markets also does not create a completed transition. And a firm that has never borrowed in LL cannot appear in the LL-to-PC origin group. The chart describes observed financing choices among borrowers receiving new loans; it does not measure every company that needs money or every failed attempt to obtain it.
The denominator is equally important. The Federal Reserve calculates each direction using the number of firms with prior loans in the origin market. The LL-to-PC percentage is therefore a share of relevant prior LL borrowers, while the PC-to-LL percentage is a share of relevant prior PC borrowers. This differs from the cited Hinzen et al. approach, which uses the total number of issuers in the origin market. Two percentages that sound like the same switching rate can therefore answer different questions.
A simple timeline shows why the measure is useful. Suppose a firm takes an LL loan in one period and a PC loan in the next period. If both loans fall within the relevant trailing window, that sequence contributes to LL-to-PC switching. If the firm takes no new loan, its financing difficulty remains invisible to a completed-switch measure. If the firm renews with the same market, it remains in the same observed state even if the new loan is more expensive or has tighter covenants. The series is therefore a record of route changes, not a complete record of changing credit conditions.
