1. Report Industry Investment Rating - The rating for treasury bonds is "Oscillating" [4] 2. Core Viewpoints of the Report - This week (May 12 - May 18), treasury bond futures fluctuated weakly due to factors such as the unexpected progress of China - US trade negotiations and marginal convergence of the capital market. Looking ahead to next week, the capital market is expected to see a slight increase in interest rates during the tax period, and the market sentiment will remain weak. Although the curve is expected to steepen in the long - term, the process will be tortuous, and there is a possibility of flattening in the short - term [13][15] 3. Summary According to the Directory 3.1 One - Week Review and Views 3.1.1 This Week's Trend Review - Treasury bond futures fluctuated weakly. On Monday, due to the unexpected statement of China - US trade negotiations, futures opened lower, then strengthened slightly and finally weakened significantly. On Tuesday, they turned from weak to strong. On Wednesday, they declined slightly. On Thursday, long - term futures performed strongly. On Friday, the curve flattened bearishly in the morning and the decline narrowed in the afternoon. As of May 16, the settlement prices of 2 - year, 5 - year, 10 - year, and 30 - year treasury bond futures main continuous contracts were 102.368, 105.695, 108.460, and 118.880 yuan respectively, with changes of +0.012, +0.005, - 0.015, and - 0.520 yuan compared to last weekend [13] 3.1.2 Next Week's Views - The capital market will be the focus. During the tax period, the capital market is expected to be slightly tighter, and the market sentiment will be weak. Although the curve is expected to steepen in the long - term, the process is tortuous, and there may be a slight flattening in the short - term. The capital interest rate is expected to rise slightly during the tax period, and the market's concern about the capital market persists [15] 3.2 Weekly Observation of Interest - Bearing Bonds 3.2.1 Primary Market - This week, 77 interest - bearing bonds were issued, with a total issuance of 939.5 billion yuan and a net financing of 707.974 billion yuan. The net financing of local government bonds increased slightly, while that of inter - bank certificates of deposit decreased [23] 3.2.2 Secondary Market - Treasury bond yields increased. As of May 16, the yields of 2 - year, 5 - year, 10 - year, and 30 - year treasury bonds were 1.48%, 1.55%, 1.68%, and 1.88% respectively, up 4.73, 6.80, 4.60, and 4.25 bp from last weekend. The 10Y - 1Y spread widened, while the 10Y - 5Y and 30Y - 10Y spreads narrowed [27] 3.3 Treasury Bond Futures 3.3.1 Price, Trading Volume, and Open Interest - Treasury bond futures fluctuated weakly. The trading volumes of 2 - year, 5 - year, 10 - year, and 30 - year treasury bond futures increased, while the open interests decreased [35][38] 3.3.2 Basis and IRR - The opportunity for the cash - and - carry strategy decreased significantly. The basis of each variety is expected to gradually return to a normal level [42] 3.3.3 Inter - Delivery and Inter - Variety Spreads - The inter - delivery spreads of each variety generally widened in the opposite direction and are expected to gradually converge to 0 in the oscillation. However, the time for deploying this strategy is limited [47] 3.4 Weekly Observation of the Capital Market - This week, the central bank's open - market operations had a net withdrawal of 475.1 billion yuan. As of May 16, capital interest rates such as R007, DR007, SHIBOR overnight, and SHIBOR 1 - week all increased. The average daily trading volume of inter - bank repurchase increased [51][53] 3.5 Weekly Overseas Observation - The US dollar index strengthened slightly, and the 10Y US Treasury yield rose slightly. As of May 9, the US dollar index increased by 0.56% to 100.9828, and the 10Y US Treasury yield rose 6 bp to 4.43%. The spread between China and the US 10Y Treasury bonds was inverted by 275 bp [60] 3.6 Weekly Observation of High - Frequency Inflation Data - This week, industrial product prices rose across the board, while agricultural product prices showed mixed trends [64] 3.7 Investment Recommendations - Next week, with weak market sentiment, short - term defense is recommended. Aggressive investors can consider buying long - term varieties on dips. In the long - term, the curve is expected to steepen, but the process is tortuous. The opportunity for the cash - and - carry strategy has decreased significantly, and attention can be paid to the strategy of the basis returning to 0. The strategy of widening the inter - delivery spread can be tried, with a quick - in - quick - out approach [2][65]
