US bond yields rise again, with 30-year rates nearing 5%, raising concerns about the deficit

    Market Concerns

    Current market concerns include the US deficit, which might be underestimated. The debate over the Republican budget suggests a potential budget deficit of 8-9% of GDP, even before considering a possible recession.

    The long-term bond market appears wary of the future outlook. If yields on 30-year bonds exceed 5% this week, it could negatively impact US equities.

    In essence, what we’ve seen recently is a disconnect between rising long-term US bond yields and the relative steadiness—if not resilience—of the dollar. Typically, elevated yields would support the currency via higher returns, but that hasn’t been the case of late. Instead, we’re seeing investors pay more attention to fiscal concerns. The noise around the federal deficit, currently running hotter than many estimates, seems to be weighing heavier on sentiment.

    Yields on long-dated Treasuries—particularly the 30-year—have climbed to their highest levels in months, nearing that symbolic 5% mark. If pierced and sustained, this would mark a strengthening expectation among bondholders that inflation could remain sticky, interest rates might stay elevated, or that fiscal slippage is now too large to ignore. Any of these would be sufficient reasons for yields to reprice upwards.

    Pressure On Equities

    When bond markets behave this way, there is a knock-on effect. Equity markets, especially in the US, feel the pressure from higher discount rates and reduced appetite for risk-sensitive sectors. It doesn’t take long for credit markets to become less accommodating. In an environment where such a funding backdrop intensifies, the equity risk premium tends to widen, putting stress on valuations.

    On balance, there appears to be little appetite right now for extending duration, especially into long-end fixed-income. This tells us something important: confidence in the fiscal path is thinning, just as debates over budget priorities grow louder. Bowman’s comments last week hinted that the Fed is unlikely to cut any time soon, only reinforcing the higher-for-longer narrative. That further steepens pressure for reallocation among change-sensitive strategies.

    From where we sit, these conditions underscore a high-sensitivity setting. Implied vols may not yet fully capture the probability of large moves, particularly if a misstep on spending negotiations throws a surprise. That introduces asymmetry, especially if options are priced with low convexity in mind.

    Should 30-year yields officially breach and hold above 5.00% by midweek, there is little near-term support likely to emerge for broader equity indexes. Moreover, funding rates in overnight swaps could become more active, raising the price of leverage, especially for shorter-term structured exposure.

    Instruments tracking SPX or NASDAQ remain vulnerable to repricing through deltas, particularly if bond-market stress triggers fresh selling across the curve. Risk-weighted positioning has already begun to shift incrementally towards cash and T-bills. These are not defensive for no reason—they reflect longer-term questions about treasury supply and auction absorption going forward.

    Boockvar made clear that the bond market is sending a warning, whether equities are listening or not. Based on last week’s close, the message is yet to fully register. This week, however, that could change quickly. We’ve seen before how equity volatility lags rate volatility by several sessions, then catches up abruptly.

    As for positioning, we are approaching a setup where gamma sensitivity returns to the fore. Consider that if volatility steepens across the wings, short-dated options could move sharply in-the-money on smaller underlying movements, leading to erratic pricing in dispersion trades. Those still playing short convexity will want tight management here.

    There is, to put it plainly, a recalibration happening in fixed-income. The lights are on in bond desks; they’re reading the same yield curves we are. A breach of 5% is not just a round number—it would mean the market is beginning to express disbelief in long-term policy direction. That disbelief could spill over into multi-asset pricing. For anyone with negative carry on exposure, the cost of hesitation may rise rapidly.
