The U.S. high-yield bond market saw a clear defensive trading pattern on Thursday. Just as the market's attention was focused on Treasury volatility following the first meeting with new Federal Reserve Chairman Kevin Warsh, more options money shifted to another point of pressure: the HYG ETF, which tracks junk bonds.
Put option trading was significantly higher.
A notable transaction that day showed an investor spending approximately $1.3 million to purchase 20,000 HYG put options expiring in January 2027 with a strike price of $75. According to ThinkorSwim data, the number of put options traded on HYG that day was approximately five times that of call options.
As of that day, the total trading volume of HYG options was approximately 226,000 contracts, of which about 190,000 were put options. This indicates that some funds are increasing their bets on a weakening of high-yield bond prices, or at least hedging credit market risk through options.
The change of leadership at the Federal Reserve leads to a revaluation of pricing.
The market is currently unable to pinpoint a single trigger for this round of bearish trading, but some participants are pointing to a change in Federal Reserve leadership. For bond traders, the market has had relatively fixed expectations regarding the policy path for a considerable period; however, with the change of chairman, this trading framework may need to be readjusted.
Zed Francis, co-founder and chief investment officer of Chicago-based investment firm Convexitas, said that bond traders have had a set policy script to follow for the past 20 years, but now they need to reassess the market, which may cause some buy-side funds to turn to the sidelines in the short term.
Falling oil prices increase pressure on the energy sector
Another factor mentioned is the continued decline in international oil prices. Following the peace agreement reached between the US and Iran, crude oil prices continued to fall, hitting their lowest level since March on Thursday. This change is particularly sensitive for the high-yield bond market, as energy companies have a significant presence in that sector.
According to iShares data, over 11% of the HYG ETF's assets are invested in the energy sector. If oil prices continue to decline, credit expectations for energy-related high-yield bonds may come under pressure, amplifying investor caution towards the entire high-yield bond sector.
From the perspective of the options structure at that time, the market was not merely trading interest rates themselves, but rather reassessing the interplay between credit risk, energy exposure, and policy expectations. High-yield bonds therefore became one of the more closely watched risk areas in this round of bond market volatility.
