InfoMoney reported that DI futures rates ended the week with cumulative gains of more than 250 basis points—equivalent to 2.5 percentage points in seven days. According to the outlet, the move occurred during the first week following Lula's victory in the presidential race. For investors, the message is straightforward: the cost of capital in Brazil has gotten more expensive, and almost no asset class emerges from this type of repricing untouched.
What Did InfoMoney Report About DI Rates This Week?
InfoMoney noted that Interbank Deposit (DI) futures contracts accumulated gains of over 250 basis points throughout the week, a performance the outlet attributes to the first week following Lula's victory in the presidential contest. In normal markets, a move of this size is distributed over months—at a pace of 25 to 50 basis points per Copom meeting, which takes place every 45 days. Concentrating this jump into a single week, without any formal decision from the Central Bank, is the market acting on its own.

Why Is a Jump of This Magnitude Outside of Copom Unusual?
When the DI curve moves without a Central Bank meeting during the period, the market is pricing risk on its own. Participants—banks, asset managers, and international funds holding Brazilian assets—are signaling that they demand higher returns to stay in Brazil. It is the price of uncertainty: the less the market believes the incoming administration will maintain control over public spending, the higher the interest rate it demands in exchange for financing the country's debt and businesses.
Fitch had already put the issue on the table even before the election results: the warning regarding fiscal uncertainty and public debt in post-election Brazil signaled precisely the risk that the DI curve is now quantifying. When long-term interest rates rise without a clear fiscal anchor, the curve steepens—a sign that the market does not believe the tightening cycle will end anytime soon. That is the backdrop for this week.
How Does This Change Fixed Income, FIIs, and Equities?
The answer depends on the type of asset. Investors in floating-rate instruments—such as Tesouro Selic, CDBs, and LCIs tied to the CDI—have the wind at their back: as the DI rises, the yields on these investments adjust upward automatically. Those who concentrated their portfolios in floating-rate assets navigate this week without significant damage, and monthly statements will reflect the higher rate in the coming months.
For holders of fixed-rate bonds, the scenario is different. When the yield curve rises, a bond purchased previously at a lower rate loses value on the secondary market—because any investor would prefer to wait for the more profitable paper available now. Investors who redeem before maturity face this difference as a loss. Those who hold to maturity receive what was originally agreed upon, and that is what ultimately matters—but this week's mark-to-market valuation turned negative. The same logic applies to Tesouro IPCA+ bonds: real yields have widened, which pressures current holders but creates an entry opportunity for those seeking long-term inflation protection with a higher yield.
For equity FIIs—shopping malls, logistics warehouses, and corporate office buildings—the impact is direct pressure on unit prices. The logic comes down to competition: when fixed income pays more, investors demand higher yields from real estate investment funds as well. Because rents do not rise at the same speed, the adjustment happens through the unit price, which falls. In a week when the U.S. dollar also surged following Lula's victory, the dual effect weighed on the sector. The outlook differs for paper FIIs with portfolios indexed to the CDI or IPCA: the underlying receivables yield more when the DI rises, meaning the fund can benefit from the exact same movement that harms equity-focused funds.
For equities, the picture is mixed. Companies with high CDI-indexed debt pay more to roll over their liabilities, and the market discounts that in their stock prices. Growth companies, whose future cash flows are discounted to present value using a higher rate, also suffer. On the other side, banks tend to benefit from higher interest rates, as their operating spreads hold steady or expand. The Ibovespa, which reached 206,000 points in the post-election historic rally, contains sectors with opposing reactions in this cycle—and the net result will depend on how much of the DI movement is accompanied by earnings revisions.
If you are invested in floating-rate assets, the week was favorable: your returns will rise alongside the DI. If you hold long-term fixed-rate bonds or Tesouro IPCA+ securities, your mark-to-market valuation turned negative—and that only matters if you need to redeem before maturity. For equity FIIs, downward pressure on unit prices is likely to persist as long as long-term interest rates remain elevated. The decision to reposition or hold depends on which asset classes make up your portfolio and what your time horizon is.
What to Watch in the Coming Days
Three fronts will determine whether this trend reverses or deepens. First, the incoming administration's fiscal signals: any announcement of spending without an equivalent revenue source or of changes to the existing fiscal framework is likely to steepen the curve further. Second, the response from Copom—if medium- and long-term inflation expectations become unanchored, the Central Bank may need to signal Selic rate hikes sooner than anticipated. Third, the behavior of U.S. interest rates: when the 10-year Treasury yield pulled back to 5.09%, relief spread to emerging markets—another pullback would provide breathing room for Brazil, while a new surge would export additional pressure to our yield curve.
Fiscal announcements from the incoming government—any uncompensated spending or changes to the fiscal framework serve as a catalyst for a further widening of the curve. If enacted, fixed-rate bonds and equity FIIs will suffer more than this week's move has already imposed.
Upcoming Copom meeting—the Central Bank will need to signal whether long-term expectations have become unanchored. An early Selic rate hike deepens the trend; a pause paired with stable anchoring stabilizes the short end of the curve.
Curve steepening—if long-term maturities (5 to 10 years) rise faster than short-term ones (up to 1 year), the curve is pricing in structural fiscal risk rather than just short-term inflation. This is the sign that the market distrusts the new government's fiscal commitment—and it is the hardest to reverse.
