固定收益点评:融资依然存在放缓压力

1. Report Industry Investment Rating No industry investment rating is provided in the report. 2. Core View of the Report - The financing situation shows a slow - down pressure, while the supply of funds increases, and the bond market is expected to gradually recover. The positive stance of the Central Economic Work Conference on macro - policies helps ease market adjustment pressure. The future interest rate trend depends on whether fiscal policies can drive the recovery of social financing growth. If the fiscal strength is limited and the social financing growth rate continues to decline, the interest rate will fall. The slowdown in real - estate sales leads to more residents' savings flowing into fixed - income assets, which is beneficial for the bond market [5][20]. 3. Summary by Related Content Credit Situation - In November, the loan growth rate continued to slow down, with obvious bill - padding characteristics. New credit was 39 billion yuan, 19 billion yuan less than the same period last year, and the new credit scale has been lower than the same period last year for 5 consecutive months. Corporate credit increased by 61 billion yuan, mainly due to the increase in short - term loans. Corporate medium - and long - term loans increased by 17 billion yuan, 4 billion yuan less than the same period last year, while bill financing increased by 33.42 billion yuan, 21.19 billion yuan more than the same period last year. Resident loans decreased by 20.63 billion yuan, 47.63 billion yuan more than the same period last year, which is consistent with the slowdown in real - estate sales [1][8]. Social Financing Situation - In November, new social financing was 2.49 trillion yuan, 159.7 billion yuan more than the same period last year, and the year - on - year growth rate of social financing stock was 8.5%, the same as last month. Corporate bonds contributed significantly to the year - on - year increase in social financing, with a net financing of 41.69 billion yuan, 17.88 billion yuan more than the same period last year. Government bond issuance was stable, with a new scale of 1.2041 trillion yuan, a slight year - on - year decrease of 104.8 billion yuan under a high base [2][10]. - Looking ahead, the social financing growth rate may face pressure. The increase in social financing growth rate in the first half of this year was mainly driven by the year - on - year increase in government bonds. However, the fiscal increment scale next year may not reach this year's level. It is expected that the social financing growth rate may slow down from the current 8.5% to about 7.5% by June next year [3][11]. M1 and M2 Situation - In November, the year - on - year growth rate of M2 was 8.0%, 0.2 percentage points lower than last month, which was consistent with the slowdown in deposit growth. The year - on - year growth rate of M1 also declined, dropping from 6.2% to 4.9%, and its two - year compound growth rate was stable at about 2%, indicating that the fluctuations were mainly due to the base effect [3][13]. Deposit Situation - In November, new deposits were 1.4 trillion yuan, 760 billion yuan less than the same period last year. Fiscal deposits decreased by 5 billion yuan, 19 billion yuan more than the same period last year. Resident deposits increased by 67 billion yuan, 12 billion yuan less than the same period last year, and corporate deposits increased by 64.53 billion yuan, 9.47 billion yuan less than the same period last year. Non - bank deposits increased by 8 billion yuan, 10 billion yuan less than the same period last year. The slowdown in deposit growth may be due to the central bank's increased capital injection [4][15].
