Commercial Paper Market Shrinks as Credit Spreads Hit 75th Percentile Amid Rising Funding Costs

As of April 01, 2026, the total commercial paper outstanding stands at $1,333.8 billion, reflecting a significant weekly contraction. This represents a week-over-week decrease of $28.7 billion, continuing a downward trend also seen in the $63.2 billion monthly decline. The current market environment is characterized by a credit spread of 35 basis points between A2/P2 and AA-rated issuers. This spread sits at the 75th percentile of historical data, suggesting a higher-than-average level of perceived risk in the credit markets. Investors are closely watching these figures as the total volume sits in the lower half of its 52-week range of $1,288.7 billion to $1,472.7 billion. The release on April 03, 2026, highlights a period of cautious positioning among both issuers and institutional buyers.

Outstanding Amounts

The total volume of commercial paper outstanding has retreated to $1,333.8 billion, marking a notable shift in corporate borrowing patterns. This week's $28.7 billion decline suggests that companies may be letting paper mature without rolling it over into new debt. Over the last month, the market has seen a substantial $63.2 billion reduction, indicating a sustained cooling in short-term credit demand. Currently, the total outstanding amount is positioned toward the lower end of the 52-week range, which peaks at $1,472.7 billion. This contraction is primarily driven by the financial sector, which saw a sharp weekly drop of $31.9 billion. Such a decrease in outstanding volume often points to tightening financial conditions or a strategic shift toward alternative funding sources.

Interest Rates

Fed Funds: 3.64% | 3M T-Bill: 3.61%

Commercial paper rates are currently trading at a premium relative to benchmark interest rates, with the 30-day AA financial rate at 3.75%. This rate sits 11 basis points above the effective Fed Funds Rate of 3.64%, reflecting a modest liquidity premium. The overnight AA financial rate is slightly lower at 3.62%, while the 90-day AA financial rate climbs to 3.90%. This upward-sloping term structure indicates that lenders are demanding higher compensation for committing capital over longer horizons. Compared to the 3-month T-Bill rate of 3.61%, commercial paper offers a 14 basis point spread to investors. These rates suggest that while funding is available, the cost of capital for even the highest-rated corporate borrowers is rising relative to risk-free benchmarks.

Credit Spreads

The credit spread between A2/P2 nonfinancial paper and AA-rated nonfinancial paper currently stands at 35 basis points. This spread is a key indicator of credit quality differentiation, as it measures the extra yield required to hold lower-rated short-term debt. At 35 basis points, the spread has widened beyond the historical median of 24 basis points, signaling increased sensitivity to credit risk. This level places the market in the 75th percentile of historical stress, suggesting that lenders are becoming more selective. A widening spread typically indicates that investors are worried about the balance sheet health of tier-2 corporate issuers. If this spread continues to climb toward the historical high of 615 basis points, it would signal severe distress in the corporate funding landscape.

Credit Spread Trend

Historical Context

The current credit spread of 35 basis points is significantly higher than the historical median of 24 basis points, placing it in the 75th percentile. Historically, the commercial paper spread has fluctuated wildly, ranging from a low of -119 basis points to a peak of 615 basis points. Data from eight similar historical periods suggests that these spread levels often precede positive equity market performance. For instance, similar spreads in August 2025 and June 2025 were followed by three-month S&P 500 returns of +4.9% and +7.9%, respectively. The median forward return for the S&P 500 from these spread levels is +4.3% over one month and +6.9% over three months. In 75% of these historical parallels, the stock market was higher six months later with a median gain of 9.4%.

Sector Breakdown

The commercial paper market is currently dominated by financial issuers, who account for $540.9 billion or 41% of the total outstanding. However, this sector saw the largest weekly decline, shedding $31.9 billion in volume. Nonfinancial corporations represent 27% of the market with $354.0 billion outstanding, also experiencing a weekly contraction of $10.3 billion. In contrast, Asset-Backed Commercial Paper (ABCP) was the only segment to grow, increasing by $13.2 billion to reach $431.1 billion. ABCP now makes up 32% of the total market, reflecting a potential shift toward collateralized short-term borrowing. The divergence between shrinking unsecured financial paper and growing asset-backed paper suggests a preference for secured structures among lenders.

Funding-Sensitive Stocks

Funding-sensitive stocks, particularly in the banking and financial services sectors, may face headwinds as financial CP outstanding contracts sharply. Banks rely on this market for short-term liquidity management, and a $31.9 billion weekly drop could signal a tightening of their internal lending capacity. Corporate issuers in the nonfinancial sector may also see their margins squeezed as the cost of rolling over short-term debt increases. Asset managers who run money market funds are likely seeing higher yields, which could attract more inflows but also increase the cost of capital for borrowers. The widening A2/P2 spread specifically impacts mid-sized companies that lack the gold-plated credit ratings of their larger peers. Investors should monitor companies with high short-term debt-to-equity ratios, as they are most vulnerable to these rising spreads.

Market Implications

The contraction in total commercial paper outstanding suggests a broader tightening of credit conditions within the financial system. As the spread vs Fed Funds sits at +11 basis points, the plumbing of the money markets is showing signs of moderate friction. Money market funds, which are the primary buyers of this paper, may be demanding higher yields to offset perceived risks in the corporate sector. This environment often leads to banks becoming more conservative with their own balance sheets, potentially slowing the pace of commercial and industrial loans. The 75th percentile spread level indicates that while we are not in a crisis, the margin for error in the credit markets is narrowing. If the trend of shrinking outstanding volume persists, it could lead to a liquidity crunch for firms that rely heavily on the overnight and 30-day markets.
