## FAQ
#### What are “bond vigilantes,” and why are they now viewed as a source of pressure for the market?
“Bond vigilantes” refers to institutional investors that express dissatisfaction with inflationary monetary policies by selling government bonds (pushing yields higher). According to Will McGough, the current rise in yields reflects renewed market concerns about inflation pressure, as well as a test of Warsh’s policy stance as the incoming FED chair.
#### What is the transmission mechanism from U.S. Treasury yields breaking above 5.2% to Bitcoin?
According to reports, rising yields increase the returns on “safe” assets such as government bonds, reducing investors’ motivation to take risk in risk assets like crypto; at the same time, they raise borrowing costs across the economy, hurt expectations for future profits, and reduce the relative attractiveness of risk assets.
#### What is the current confirmed status of U.S.-Iran talks, and where do the two sides disagree?
According to the Wall Street Journal, citing regional mediators and U.S. officials, Iran’s position in the negotiations has not changed significantly compared with the proposals that previously failed to make progress. Iran’s core demands include ending hostilities, lifting sanctions, war reparations, and playing a supervisory role in the Strait of Hormuz; the U.S. still has clear disagreements with Iran on the issue of closing or pausing Iran’s nuclear program.
