TechFlow news, on March 21, according to CoinDesk, the ICE/BofA US High Yield Index Option-Adjusted Spread (OAS), a key indicator of economic sentiment and corporate credit health, has retreated from recent highs, supporting a rebound in risk appetite for cryptocurrency and stock markets. However, analysts believe this relief may be short-lived.
The OAS measures the average yield difference between dollar-denominated high-yield corporate bonds and US Treasuries, adjusted for embedded options within the bonds. Widely regarded as a barometer of credit risk, a widening spread typically reflects growing investor concerns about corporate defaults or economic weakness.
Currently, the OAS has declined to 3.2% from a six-month high of 3.4% earlier this month, supporting renewed gains in Bitcoin (BTC) and the Nasdaq. Prior to this, the spread had surged by 100 basis points over four weeks through mid-March as Trump's tariff policies sparked recession fears, causing Bitcoin to fall below $80,000 and inflicting heavy losses on the Nasdaq.
However, analysts expect the OAS spread to widen further in the coming weeks as the negative impacts of Trump's tariff policies become more apparent. Hans Mikkelsen, Managing Director of Credit Strategy at TD Securities, stated in a recent client report: "We think this is just the beginning, and things will get worse before they get better."
From a technical analysis perspective, the OAS has broken above a three-year declining trendline, a highly cautionary signal for risk asset investors.
