May NY world sugar #11 (SBK22) on Wednesday closed down -0.17 (-0.91%), and May London white sugar #5 (SWK22) closed down -0.10 (-0.02%). Sugar prices Wednesday closed moderately lower, with NY sugar falling to a fresh 1-1/2 week low.  Weakness in crude prices (CLJ22) Wednesday weighed on sugar prices.  Lower crude prices undercut ethanol prices and may prompt Brazil's sugar mills to divert more cane crushing to sugar production rather than ethanol, thus boosting sugar supplies. A negative factor for sugar is the outlook that larger sugar crop sizes in India and Thailand will offset reduced sugar production in Brazil.  Last Friday, the Indian Sugar Mills Association (ISMA) raised its India 2021/22 sugar production estimate to 33.3 MMT from a Jan estimate of 31.5 MMT and predicted India's 2021/22 sugar exports would jump to a record 7.5 MMT.   India is the world's second-largest sugar producer. Also, the Thailand Office of the Cane & Sugar Board reported Jan 10 that Thailand 2021/22 sugar production during Dec 7-Jan 6 rose +58% y/y to 1.9 MMT.  Thailand is the world's second-largest sugar exporter. In a bullish factor, the International Sugar Organization (ISO) recently cut its global 2021/22 sugar deficit estimate to -1.93 MMT from a November estimate of -2.55 MMT. Reduced sugar output in Brazil is bullish for prices after Unica reported Tuesday that 2021/22 Center-South sugar production Oct through Feb was 32.038 MMT, down -16.2% y/y.  Also, the sugar content in the sugarcane crushed fell -1.5% y/y to 142.96 kg/ton from 145.09 kg/ton a year earlier.   Sugar has underlying support from the recent damage to Brazil's sugar crops from frost and drought.  Conab, on Nov 23, cut its Brazil 2021/22 sugar production estimate to 33.9 MMT from an Aug forecast of 36.9 MMT, down -17.9% y/y.  Conab projects Brazil's 2021/22 sugarcane crushing will fall to 525 MMT, down -13% y/y and the lowest in 10 years.
