➡️ Dollar privilege: The Fed controls the supply of US dollars and the world still queues to buy US Treasuries. Despite recent US Treasury sell-offs, there's little alternative as a reserve asset for central banks apart from Gold.
Why this might be a cause for concern
➡️ Confidence fragility: A tariff shock, inflation flare-up, or Trump's "Big Beautiful Bill" could jolt bond vigilantes awake. A sell-off could see this interest expense rise dramatically from this trillion dollar level.
➡️ More credit risk is now being priced in since Moody's downgrade, which could also make US debt more expensive to service in the future.
