Bonds and loans get priced by institutions with deep research desks, and those desks tend to see trouble coming before the rest of us do. So when credit conditions tighten, when spreads widen or banks pull back on lending, it usually takes two to four months for that to bleed into equity and crypto prices. That lag is exactly what makes credit one of the more useful leading indicators you can watch.
What credit spreads actually tell you
A credit spread is the extra yield a corporate bond pays over a risk-free government bond. Tight spreads mean the credit market is relaxed and happy to take risk. Wide spreads mean it is stressed and demanding more compensation to hold the same paper.
The level matters, but the direction matters more. Spreads rising off a low base still tell you conditions are deteriorating, and that will eventually reach every risk asset. The gap between high-yield junk bonds and investment-grade is the most informative slice, because it captures how the market is pricing default risk on the shakiest borrowers.
If you trade crypto, the one external series I would keep on the screen is the ICE BofA US High Yield Index OAS. Under 300 basis points, credit is loose and risk-taking is supported. A spike above 500 means the stress is real enough to drag on all risk assets. Past 800, the credit market is basically pricing a recession.
What the banks are telling regulators
The Fed's Senior Loan Officer Opinion Survey, the SLOOS, just asks banks whether they are tightening or loosening lending standards. It has been a reliable lead on economic activity with something like a two-to-three-quarter head start. When a lot of banks report tightening, credit is getting harder to get, activity slows, and prices follow later.
It is quarterly, so it is slow. But it is dependable, and it sets the backdrop your position sizing should respect. Banks tightening means dial down risk. Banks easing means the environment is on your side.
The lending that never shows up in the surveys
Traditional metrics miss a growing chunk of lending that happens outside regulated banks. Private credit funds, direct lending platforms, and DeFi protocols all extend credit without ever touching a bank survey.
For crypto, DeFi lending is your native read. When stablecoin borrow rates are high, people want leverage and credit is loose. When those rates collapse, there is excess supply and no demand, and credit is tight. This one moves faster than any traditional metric and it maps more directly onto crypto price action, which is why it is worth checking often.
Credit events and how they spread
A single default can cascade if the entity that blows up is wired into everyone else. FTX is the obvious example. One credit event turned into cascading liquidations, frozen assets, and contagion into protocols and exchanges that looked completely unrelated on paper.
So watching the credit health of the big crypto counterparties, the exchanges, lenders, and stablecoin issuers, is the crypto version of watching CDS prices on major banks. When solvency questions start circling a major counterparty, trimming exposure early has usually been the right call, even the times the fear turned out to be overblown. At Blockcircle we lean on this the same way, treating counterparty stress as a reason to de-risk before it shows up in the tape.
Working it into your process
High-yield spreads weekly. SLOOS quarterly. DeFi rates daily or weekly. When all three read loose, the environment supports taking risk across crypto and prediction markets. When any one of them flips toward tightening, start peeling off exposure in small steps rather than waiting for the tightening to hit prices on its own.
