Investors have been holding unhedged US dollar assets to capture both high yields and currency appreciation, a speculative strategy traditionally used for emerging market local currency bonds. This parallel indicates a shift in risk perception, where US assets are no longer seen as a pure safe haven.

Concerns over US term premium have receded partly because the Treasury buyer base has stabilized. The declining share of price-insensitive buyers (Fed, foreign investors, banks), which fell from 75% to 50% over a decade, has finally stopped falling, creating a more supportive demand backdrop.

A major shift in market technicals has occurred, with overseas investors becoming the dominant buyers of US corporate debt. Their share of net inflows jumped from a historical average of one-third to 45% in early 2024, providing a powerful tailwind for the asset class.

Foreign central banks, the Fed, and commercial banks—buyers who are insensitive to price—are shrinking their share of the Treasury market. This forces price-sensitive investors to absorb a massive supply of new debt, structurally increasing bond volatility and pushing institutions to adopt gold as a more reliable portfolio diversifier.

The sharp sell-off in short-term US yields was magnified by technical dynamics, not just fundamentals. Pre-existing long positions and systematic selling from Commodity Trading Advisors (CTAs), triggered when yields broke the 200-day moving average, created a snowball effect that pushed yields higher.

The failure of Silicon Valley Bank was not an isolated event but a predictable outcome of a global issue. Many entities, including pension funds and insurance companies, are "leveraged long" on government bonds whose values plummeted as interest rates rose.

Since 2022, highly leveraged hedge funds have bought 37% of net long-term Treasury issuance. This concentration makes the world’s most important market exceptionally vulnerable, as any volatility spike could trigger forced mass selling (degrossing) from these funds.

The dominance of leveraged hedge funds as the marginal buyers of long-term bonds means that during a crisis, bonds are sold off alongside equities. This forced de-leveraging negates their traditional safe-haven role, transforming them into a risk asset that falls during market stress.

For 40 years, falling rates pushed 'safe' bond funds into increasingly risky assets to chase yield. With rates now rising, these mis-categorized portfolios are the most vulnerable part of the financial system. A crisis in credit or sovereign debt is more probable than a stock-market-led crash.
