TREASURY WRAP: T-NOTE FUTURES (U6) SETTLE 9 TICKS LOWER AT 108-16

Treasury yields rise as long end briefly pares post-buyback rally. At settlement, 2-year +2.1bps at 4.183%, 3-year +2.8bps at 4.264%, 5-year +4.3bps at 4.382%, 7-year +4.9bps at 4.524%, 10-year +5.1bps at 4.692%, 20-year +4.2bps at 5.218%, 30-year +4.0bps at 5.229%. THE DAY: Treasury yields rose across the curve on Thursday, with the 30-year briefly returning to levels seen before Wednesday's Treasury buyback announcement. The belly and long end led the move higher, resulting in a steeper curve and reversing some of the flattening seen following the Treasury's decision to increase long-end liquidity-support buybacks. Treasury futures briefly took another leg higher after US Treasury Secretary Bessent told CNBC that the upsized long-end buybacks could exceed USD 4bln per operation, consistent with the "at least" USD 4bln language announced on Wednesday. Bessent reiterated that the programme is intended to enhance liquidity in thinner areas of the curve, although he acknowledged that part of the move is about signalling. When asked what the Treasury could do if long-end yields continued to rise, Bessent said it has a large toolkit but provided little additional detail. Despite the initial move higher in futures during his remarks, the move subsequently reversed, with Treasuries settling lower across the curve. The reversal suggests the buyback announcement may help dampen pressure at the long end but, at least so far, has not fundamentally altered the underlying direction of yields - in fitting with remarks from ING on Wednesday. On corporate issuance, the Treasury Secretary said that corporate issuance is "yield agnostic" and noted that, as a company, he would consider increasing issuance in the 5-year. Meanwhile, he will also soon be announcing an increased focus on fiscal consolidation, noting the US will grow itself out of the debt burden, stressing the USD 40tln debt figure is not a magic number. Elsewhere, Fed's Musalem reiterated that he favoured raising rates in July, arguing that hiking now could avoid the need for larger moves further down the line. Meanwhile, Fed's Daly reiterated that she favoured holding rates and believes policy is currently in a good place. Economic data were mixed, with Initial Jobless Claims remaining low, while Continuing Claims for the preceding week rose. The 30-year TIPS auction was strong again. The 1.8bp stop-through, above-average bid-to-cover, exceptionally strong indirect participation and very low dealer allocation pointed to very strong demand, with the substantially higher real yield on offer likely helping attract investors to long-end inflation-protected duration. Crude prices were also firmer amid reports that the Houthis are preparing to enter a new phase of escalation against Saudi Arabia. Meanwhile, Iranian Supreme Leader adviser Rezaei said the best response to Trump's escalation of economic warfare would be to withdraw from the Nuclear Non-Proliferation Treaty, which legally commits Iran to maintaining a peaceful nuclear programme. US President Trump also reportedly told his team that the chances of reaching a deal with Iran are slim and ordered a freeze on talks for several weeks.
