When a geopolitical crisis arises, investors buy U.S. Treasury bonds. This is an old rule in finance that is taught in introductory economics classes and repeated each time. Prices rise and yields fall as they flee to the security of government bonds. Through the Gulf War, September 11, and the 2008 financial crisis, it has operated in this manner for decades. The yield on the 10-year Treasury note has consistently served as an inverse fear gauge. Yields decrease as fear increases.
In 2026, that rule is ineffective. And one of the more concerning developments in the financial markets at the moment is that deviation from the anticipated pattern.

The benchmark 10-year Treasury yield has increased from about 3.96 percent to as high as 4.45 percent since the U.S. military strikes on Iran in late February. This is a negative development for investors who were relying on bonds as their traditional safe haven. On March 30, 2026, the yield was 4.394 percent, slightly lower than the previous session but still high enough to change borrowing costs for the whole economy. The 52-week range spans from a low of 3.864 percent to 4.632 percent, and there is currently genuine market tension regarding which end of that range the yield is moving toward.
The explanation includes the Iranian conflict, but not in the way that most people think. The term premium, the extra yield that investors demand to make up for holding long-term debt in situations where the future feels truly uncertain, is the direct mechanism rather than investor panic selling Treasury bonds.
Investors want more than just safety when geopolitical risk remains high for weeks instead of days, when oil prices rise to almost $99 per barrel, and when inflation expectations begin to rise once more. Higher yields are the result of this additional compensation. According to this reading, the bond market is not broken. It’s asking for more from a world it doesn’t completely trust.
Ordinary Americans are directly experiencing the collateral damage caused by that repricing. In just a few weeks, mortgage rates have increased from about 5.99 percent to over 6.6 percent, which means that a typical home loan will now cost more than $1,500 more annually. The price of gasoline has increased from $2.79 per gallon in late February to almost $3.79, further straining already tight household budgets on a daily basis.
There is a connection between these numbers. Expectations for inflation rise as oil prices rise. Treasury yields rise as inflation expectations rise. Mortgage rates rise in response to rising yields. From a military action in the Middle East to a homebuyer in Ohio doing math on a kitchen table, there is a cascade of consequences.
As this develops, there is a sense that the bond market is no longer, at least momentarily, the anchor it once was. This week, Bob Doll of Crossmark Global Investments made an appearance on CNBC, voicing doubts about whether bonds are even a good investment at the current price. This is the kind of cautious institutional commentary that resonates differently when it comes from a veteran of fixed incomes.
Following a poorly received bond auction, the two-year Treasury yield increased, indicating that demand is unstable even at the short end of the curve. Yields must increase to draw buyers when they avoid government debt auctions. That’s supply and demand operating exactly as intended; it just makes things more difficult.
The yield has been closely monitored by cryptocurrency markets, and for good reason. In comparison to other riskier assets, Bitcoin, which is currently trading close to $66,600, has demonstrated unexpected relative stability. However, the derivatives market reveals a more cautious picture, with traders paying high premiums for put options, effectively purchasing protection against a more severe decline.
The reasoning is simple: investors have a real alternative to volatile assets when the 10-year Treasury yields more than 4%, which was not the case when yields were close to zero. The argument for capital rotation is no longer theoretical. It is evident in Bitcoin ETF flows, which have seen net inflows of $1.13 billion since the start of the Iran escalation but experienced consecutive outflows in the last few days of March as macro pressure increased.
It’s important to keep in mind yields. During the early months of the pandemic, when the Federal Reserve was flooding the system with liquidity and no one knew how bad things would get, the 10-year hit its lowest point in March 2020 at 0.32 percent, a level that now seems almost unreal. Before a dramatic reversal, the all-time modern high of 5.02 percent was reached in October 2023.
Although the current level, which is in the mid-4 percent range, is neither extreme, the direction of travel is just as important as the level itself, and at the moment, the direction feels uneasy in a way that is difficult to ignore. It’s still unclear if yields are increasing in anticipation of a 5 percent retest or if a diplomatic development completely alters the equation. Like everyone else, the bond market is waiting for that response.
